**CrudFilter**: This type can be either a `LogicalFilter` or a `ConditionalFilter`.```typescript type CrudFilter = LogicalFilter | ConditionalFilter;``` **Source** (<https://refine.dev/docs/core/interface-references#crudfilter>)
**CrudFilters**: This is an array of `CrudFilter`.```typescript type CrudFilters = CrudFilter[];``` **Source** (<https://refine.dev/docs/core/interface-references/#crudfilters>)

### Example Usage

When you need to create filters for a table, you can define them using the

CrudFilters

CrudFilters type. Here’s an example from a

useTable

useTable

hook:

import { HttpError } from "@refinedev/core";
import { Dayjs } from "dayjs";

const { searchFormProps } = useTable<IPost, HttpError, { title: string; createdAt: [Dayjs, Dayjs] }>({
    onSearch: (params) => {
        const filters: CrudFilters = [];
        const { q, createdAt } = params;

        filters.push(
            {
                field: "q",
                operator: "eq",
                value: q,
            },
            {
                field: "createdAt",
                operator: "gte",
                value: createdAt ? createdAt[0].toISOString() : undefined,
            },
            {
                field: "createdAt",
                operator: "lte",
                value: createdAt ? createdAt[1].toISOString() : undefined,
            },
        );

        return filters;
    },
});

import { HttpError } from "@refinedev/core";
import { Dayjs } from "dayjs";

const { searchFormProps } = useTable<IPost, HttpError, { title: string; createdAt: [Dayjs, Dayjs] }>({
    onSearch: (params) => {
        const filters: CrudFilters = [];
        const { q, createdAt } = params;

        filters.push(
            {
                field: "q",
                operator: "eq",
                value: q,
            },
            {

            },
        );

        return filters;
    },
});

import { HttpError } from "@refinedev/core";
import { Dayjs } from "dayjs";

const { searchFormProps } = useTable<IPost, HttpError, { title: string; createdAt: [Dayjs, Dayjs] }>({

Extending Filters for Deep Filtering

K

kapa.ai•6/10/24, 8:12 AM

If you need to perform deep filtering, especially with providers like Strapi, you might need to transform the filter format. Here’s an example of how you can handle deep filters:

const filter = [
    {
        field: "chef[restaurants][stars]",
        operator: "eq",
        value: "John",
    },
];

const filter = [
    {
        field: "chef[restaurants][stars]",
        operator: "eq",
        value: "John",
    },
];

const filter = [
    {
        field: "chef[restaurants][stars]",
        operator: "eq",
        value: "John",
    },
];

const filter = [
    {
        field: "chef[restaurants][stars]",
        operator: "eq",
        value: "John",
    },
];

This converts to:

/api/restaurants?filters[chef][restaurants][stars][$eq]=5

/api/restaurants?filters[chef][restaurants][stars][$eq]=5

/api/restaurants?filters[chef][restaurants][stars][$eq]=5

/api/restaurants?filters[chef][restaurants][stars][$eq]=5
Source (https://github.com/refinedev/refine/issues/2127)

Helper Functions for Strapi

To make it easier, you can use helper functions to transform Strapi filters into refine filters:

import { strapiToRefineFilters } from "@pankod/refine-strapi-v4";

import { strapiToRefineFilters } from "@pankod/refine-strapi-v4";

import { strapiToRefineFilters } from "@pankod/refine-strapi-v4";

import { strapiToRefineFilters } from "@pankod/refine-strapi-v4";

To achieve the functionality of using the

icontains

icontains

icontains

icontains operator, which is not directly available, you can use the

contains

contains

contains

contains operator as a workaround. The

contains

contains

contains

contains operator performs a case-insensitive search by default in many systems. Here’s how you can implement it using the

onSearch

onSearch

onSearch

onSearch function:

Example Code

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
  id: number;  
  title: string;  
}  
  
const PostCreate: React.FC = () => {  
  const { selectProps } = useSelect<ICategory>({  
    resource: "categories",  
    onSearch: (value) => [  
      {  
        field: "source_name",  
        operator: "contains",  // Use "contains" as a workaround for "icontains"
        value,  
      },  
    ],  
  });  
  
  return (  
    <Select  
      placeholder="Select a category"  
      style={{ width: 300 }}  
      {...selectProps}  
    />  
  );  
};

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
  id: number;  
  title: string;  
}  
  
const PostCreate: React.FC = () => {  
  const { selectProps } = useSelect<ICategory>({  
    resource: "categories",  
    onSearch: (value) => [  
      {  
        field: "source_name",  
        operator: "contains",  // Use "contains" as a workaround for "icontains"
        value,  
      },  
    ],  
  });  
  
  return (  
    <Select  
      placeholder="Select a category"  
      style={{ width: 300 }}  
      {...selectProps}  
    />  
  );  
};

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
  id: number;  
  title: string;  
}  
  
const PostCreate: React.FC = () => {  
  const { selectProps } = useSelect<ICategory>({  
    resource: "categories",  
    onSearch: (value) => [  
      {  
        field: "source_name",  
        operator: "contains",  // Use "contains" as a workaround for "icontains"
        value,  
      },  
    ],  
  });  
  
  return (  
    <Select  
      placeholder="Select a category"  
      style={{ width: 300 }}  
      {...selectProps}  
    />  
  );  
};

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
  id: number;  
  title: string;  
}  
  
const PostCreate: React.FC = () => {  
  const { selectProps } = useSelect<ICategory>({  
    resource: "categories",  
    onSearch: (value) => [  
      {  
        field: "source_name",  
        operator: "contains",  // Use "contains" as a workaround for "icontains"
        value,  
      },  
    ],  
  });  
  
  return (  
    <Select  
      placeholder="Select a category"  
      style={{ width: 300 }}  
      {...selectProps}  
    />  
  );  
};

Explanation

Operator: The
```
contains
```
contains
```
contains
```
contains
operator is used to perform a case-insensitive search. This is a common approach when
```
icontains
```
icontains
```
icontains
```
icontains
is not available.
onSearch Function: The
```
onSearch
```
onSearch
```
onSearch
```
onSearch
function is used to set the search value and apply the filter.

### Additional Information

If you need more advanced filtering capabilities or if your backend supports custom operators, you might need to handle this on the server side or extend the refine framework to support custom operators.

For more information, you can refer to the useSelect documentation (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-select/#onsearch).

@kapa.ai how do i filter a column which has relational data like customer name and i wanrt to put a filter that uss contains to search it select: "*,agent(id,name),customer(id,name),company(id,name)"

To filter a column with relational data, such as a customer name, using the

contains

contains

contains

contains operator, you can structure your query to include the relational fields. Here's how you can achieve this:

Example Code

When dealing with relational data, you typically need to specify the path to the relational field in your filter. Here's an example of how you might set up such a filter:

import { useTable } from "@refinedev/core";

const { filters, setFilters } = useTable({
    filters: {
        initial: [
            {
                field: "customer.name",  // Specify the path to the relational field
                operator: "contains",   // Use the "contains" operator for filtering
                value: "John Doe",      // The value you are searching for
            },
        ],
    },
});

// To update the filters dynamically
setFilters([
    {
        field: "customer.name",
        operator: "contains",
        value: "Jane Doe",
    },
]);

import { useTable } from "@refinedev/core";

const { filters, setFilters } = useTable({
    filters: {
        initial: [
            {
                field: "customer.name",  // Specify the path to the relational field
                operator: "contains",   // Use the "contains" operator for filtering
                value: "John Doe",      // The value you are searching for
            },
        ],
    },
});

// To update the filters dynamically
setFilters([
    {
        field: "customer.name",
        operator: "contains",
        value: "Jane Doe",
    },
]);

import { useTable } from "@refinedev/core";

const { filters, setFilters } = useTable({
    filters: {
        initial: [
            {
                field: "customer.name",  // Specify the path to the relational field
                operator: "contains",   // Use the "contains" operator for filtering
                value: "John Doe",      // The value you are searching for
            },
        ],
    },
});

// To update the filters dynamically
setFilters([
    {
        field: "customer.name",
        operator: "contains",
        value: "Jane Doe",
    },
]);

import { useTable } from "@refinedev/core";

const { filters, setFilters } = useTable({
    filters: {
        initial: [
            {
                field: "customer.name",  // Specify the path to the relational field
                operator: "contains",   // Use the "contains" operator for filtering
                value: "John Doe",      // The value you are searching for
            },
        ],
    },
});

// To update the filters dynamically
setFilters([
    {
        field: "customer.name",
        operator: "contains",
        value: "Jane Doe",
    },
]);

Explanation

Field Path: Use the dot notation (
```
customer.name
```
customer.name
```
customer.name
```
customer.name
) to specify the path to the relational field you want to filter.
Operator: The
```
contains
```
contains
```
contains
```
contains
operator is used to perform a case-insensitive search on the specified field.
Dynamic Updates: You can dynamically update the filters using the
```
setFilters
```
setFilters
```
setFilters
```
setFilters
function.

### Additional Considerations

Backend Support: Ensure that your backend supports filtering on relational fields and that the API is set up to handle such queries.
Data Provider: Depending on the data provider you are using, you might need to adjust the query format to match the provider's requirements.

For more detailed information on filtering and relational data handling, you can refer to the useTable documentation (https://refine.dev/docs/data/hooks/use-table/#filtering).

Let me check the knowledge base for you again. One moment!

K

kapa.ai•10/19/24, 5:58 PM

----------------------
When you encounter issues with unexpected columns appearing or fields like customer names showing as blank, it could be due to several reasons related to how the data is being fetched and displayed. Here are some potential causes and solutions:

Potential Causes

Incorrect Field Path: Ensure that the field path specified in your filter matches the structure of the data returned by your API. If the path is incorrect, it might not fetch the expected data.
Data Population: If you're using a data provider like Strapi, make sure that the related fields are properly populated. This is often done using the
```
populate
```
populate
```
populate
```
populate
parameter in your query.
API Response Structure: Check the structure of the API response to ensure it includes the relational data. If the API does not return the expected fields, they will appear blank.
Table Configuration: Ensure that your table configuration correctly maps the data fields to the table columns. If there are mismatches, it might display incorrect or unexpected columns.

### Solutions

**Verify API Query**: Double-check your API query to ensure it includes the necessary relational data. For example, using `populate` in Strapi:```typescriptconst { tableProps } = useTable({ meta: { populate: ["customer", "agent", "company"], // Ensure these are correctly populated },});```
**Check Field Paths**: Make sure the field paths in your filters and table columns match the API response structure. For example:```typescript{ field: "customer.name", operator: "contains", value: "John Doe",}```
**Inspect API Response**: Use tools like Postman or browser developer tools to inspect the API response and verify that it includes the expected data.

K

kapa.ai•10/19/24, 5:58 PM

Adjust Table Columns: Ensure your table columns are correctly configured to display the data. For example:

<Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

<Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

<Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

<Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

If these steps do not resolve the issue, you might need to review the API documentation or consult with your backend team to ensure the data is being provided as expected. For more information on handling relational data, you can refer to the useTable documentation (https://refine.dev/docs/data/hooks/use-table/#filtering).

To address the issue where searching by customer name results in extra columns or records being displayed, you should ensure that your filtering logic and table configuration are correctly set up. Here are some steps and considerations to help you resolve this:

Steps to Resolve

Ensure Correct Filter Configuration:
- Make sure that the filter is correctly targeting the relational field. For example, if you are filtering by
```
customer.name
```
  customer.name
```
customer.name
```
  customer.name
  , ensure that the field path is correct and matches the API response structure.

   const { filters, setFilters } = useTable({
       filters: {
           initial: [
               {
                   field: "customer.name",  // Ensure this matches the API response
                   operator: "contains",
                   value: "John Doe",
               },
           ],
       },
   });

   const { filters, setFilters } = useTable({
       filters: {
           initial: [
               {
                   field: "customer.name",  // Ensure this matches the API response
                   operator: "contains",
                   value: "John Doe",
               },
           ],
       },
   });

   const { filters, setFilters } = useTable({
       filters: {
           initial: [
               {

                   value: "John Doe",
               },
           ],
       },
   });

   const { filters, setFilters } = useTable({
       filters: {
           initial: [
               {
                   field: "customer.name",  // Ensure this matches the API response
                   operator: "contains",
                   value: "John Doe",
               },
           ],
       },
   });

**Verify API Response**:
- Use tools like Postman or browser developer tools to inspect the API response. Ensure that the response includes the
```
customer.name
```
  customer.name
```
customer.name
```
  customer.name
  field and that it is populated correctly.
**Check Table Column Configuration**:
- Ensure that your table columns are configured to display the correct data fields. If there are extra columns, they might be due to incorrect column definitions.

   <Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

   <Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

   <Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

   <Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

**Filter Logic**:
- Ensure that the filter logic is correctly applied and that it filters out records that do not match the search criteria. If the logic is incorrect, it might include records that should be excluded.
**Backend Filtering**:
- If the filtering is done server-side, ensure that the backend logic correctly implements the
```
contains
```
  contains
```
contains
```
  contains
  operator and returns only the matching records.

**Populate Relational Data**: If using a data provider like Strapi, ensure that relational data is populated using the `populate` parameter.
**Debugging**: Add console logs or use debugging tools to trace the data flow and identify where the filtering logic might be failing.

If these steps do not resolve the issue, you may need to consult the API documentation or backend team to ensure the data is being provided and filtered as expected. For more detailed information on filtering and relational data handling, you can refer to the useTable documentation (https://refine.dev/docs/data/hooks/use-table/#filtering).

When using Supabase as a data provider in refine, and you encounter issues with filtering relational data, you need to ensure that your query and filter setup are correctly configured to handle relational fields. Here’s how you can address this:

Steps to Filter Relational Data with Supabase

Ensure Correct Field Path:
- When filtering by a relational field such as
```
customer.name
```
  customer.name
```
customer.name
```
  customer.name
  , ensure that the field path is correctly specified in your filter configuration.

   const { filters, setFilters } = useTable({
       filters: {
           initial: [
               {
                   field: "customer.name",  // Ensure this matches the structure of your Supabase data
                   operator: "contains",
                   value: "John Doe",
               },
           ],
       },
   });

   const { filters, setFilters } = useTable({
       filters: {
           initial: [
               {
                   field: "customer.name",  // Ensure this matches the structure of your Supabase data
                   operator: "contains",
                   value: "John Doe",
               },
           ],
       },
   });

   const { filters, setFilters } = useTable({
       filters: {
           initial: [
               {
                   field: "customer.name",  // Ensure this matches the structure of your Supabase data
                   operator: "contains",
                   value: "John Doe",
               },
           ],
       },
   });

   const { filters, setFilters } = useTable({
       filters: {
           initial: [
               {
                   field: "customer.name",  // Ensure this matches the structure of your Supabase data
                   operator: "contains",
                   value: "John Doe",
               },
           ],
       },
   });

**Verify Supabase Query**:
- Ensure that your Supabase query is correctly set up to include the necessary relational data. You might need to adjust your query to ensure it fetches the related fields.
**Check Table Column Configuration**:
- Make sure your table columns are set up to display the correct data fields. If there are extra columns, they might be due to incorrect column definitions.

   <Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

   <Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

   <Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

   <Table.Column dataIndex={["customer", "name"]} title="Customer Name" />

**Inspect API Response**:
- Use tools like Postman or browser developer tools to inspect the API response from Supabase. Ensure that the response includes the
```
customer.name
```
  customer.name
```
customer.name
```
  customer.name
  field and that it is populated correctly.
**Backend Filtering**:
- If the filtering is done server-side, ensure that the Supabase query correctly implements the
```
contains
```
  contains
```
contains
```
  contains
  operator and returns only the matching records.

**Supabase Client Configuration**: Ensure that your Supabase client is correctly configured and that you have access to the necessary relational data.
**Debugging**: Add console logs or use debugging tools to trace the data flow and identify where the filtering logic might be failing.

For more detailed information on using Supabase with refine, you can refer to the Supabase data provider documentation (https://refine.dev/docs/data/packages/supabase/). If you have further questions or need additional customization, feel free to ask!

To handle column filtering manually with Supabase as your data provider, you can bypass the built-in filtering mechanisms and implement your own logic. Here’s a step-by-step guide on how to achieve this:

Manual Filtering Steps

Fetch Data Manually:
- Use the Supabase client to fetch data manually, applying your filter logic directly in the query.

   import { createClient } from '@supabase/supabase-js';

   const supabase = createClient('your-supabase-url', 'your-anon-key');

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Adjust the select statement to include relational data
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   import { createClient } from '@supabase/supabase-js';

   const supabase = createClient('your-supabase-url', 'your-anon-key');

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Adjust the select statement to include relational data
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   import { createClient } from '@supabase/supabase-js';

   const supabase = createClient('your-supabase-url', 'your-anon-key');

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Adjust the select statement to include relational data
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   import { createClient } from '@supabase/supabase-js';

   const supabase = createClient('your-supabase-url', 'your-anon-key');

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Adjust the select statement to include relational data
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

Update State with Filtered Data:
- Once you have fetched the data, update your component’s state to reflect the filtered results.

   const [filteredData, setFilteredData] = useState([]);

   const handleSearch = async (searchValue: string) => {
       const data = await fetchFilteredData(searchValue);
       setFilteredData(data);
   };

   const [filteredData, setFilteredData] = useState([]);

   const handleSearch = async (searchValue: string) => {
       const data = await fetchFilteredData(searchValue);
       setFilteredData(data);
   };

   const [filteredData, setFilteredData] = useState([]);

   const handleSearch = async (searchValue: string) => {
       const data = await fetchFilteredData(searchValue);
       setFilteredData(data);
   };

   const [filteredData, setFilteredData] = useState([]);

   const handleSearch = async (searchValue: string) => {
       const data = await fetchFilteredData(searchValue);
       setFilteredData(data);
   };

Render the Filtered Data:
- Use the filtered data to render your table or list component.

   return (
       <Table dataSource={filteredData} rowKey="id">
           <Table.Column title="Customer Name" dataIndex={['customer', 'name']} />
           {/* Add other columns as needed */}
       </Table>
   );

   return (
       <Table dataSource={filteredData} rowKey="id">
           <Table.Column title="Customer Name" dataIndex={['customer', 'name']} />
           {/* Add other columns as needed */}
       </Table>
   );

   return (
       <Table dataSource={filteredData} rowKey="id">
           <Table.Column title="Customer Name" dataIndex={['customer', 'name']} />
           {/* Add other columns as needed */}
       </Table>
   );

   return (
       <Table dataSource={filteredData} rowKey="id">
           <Table.Column title="Customer Name" dataIndex={['customer', 'name']} />
           {/* Add other columns as needed */}
       </Table>
   );

Supabase Query: The
```
ilike
```
ilike
```
ilike
```
ilike
function is used for case-insensitive filtering, which is similar to the
```
contains
```
contains

contains
operator.
Manual Fetching: By manually fetching data, you have full control over the query and can ensure that only the desired records are returned.
State Management: Use React state to manage and display the filtered data.

This approach allows you to handle filtering manually, giving you more flexibility and control over the data retrieval process. If you need further customization or encounter issues, you can refer to the Supabase documentation (https://supabase.io/docs) for more details on querying and filtering data.

----------------------
To manually handle column filtering in your example using Supabase, you can follow these steps. This approach involves fetching data directly from Supabase with custom filtering logic and then updating your component's state to display the filtered results.

Step-by-Step Guide

Set Up Supabase Client:
- Ensure you have the Supabase client set up in your project.

   import { createClient } from '@supabase/supabase-js';

   const supabase = createClient('your-supabase-url', 'your-anon-key');

   import { createClient } from '@supabase/supabase-js';

   const supabase = createClient('your-supabase-url', 'your-anon-key');

   import { createClient } from '@supabase/supabase-js';

   const supabase = createClient('your-supabase-url', 'your-anon-key');

   import { createClient } from '@supabase/supabase-js';

   const supabase = createClient('your-supabase-url', 'your-anon-key');

Create a Function to Fetch Filtered Data:
- Write a function that queries Supabase with the desired filter. Use the
```
ilike
```
  ilike
```
ilike
```
  ilike
  function for case-insensitive filtering.

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Adjust the select statement to include relational data
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Adjust the select statement to include relational data
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Adjust the select statement to include relational data
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Adjust the select statement to include relational data
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

Manage State for Filtered Data:
- Use React state to store and manage the filtered data.

```typescript
import React, { useState } from 'react';

const MyComponent = () => {
const [filteredData, setFilteredData] = useState([]);

const handleSearch = async (searchValue: string) => {
const data = await fetchFilteredData(searchValue);
setFilteredData(data);
};

To ensure that only relevant results are displayed and irrelevant results are filtered out, you need to make sure that your filtering logic is correctly implemented and that the data returned from Supabase matches your expectations. Here’s how you can refine the process:

Steps to Ensure Relevant Results

Verify Supabase Query:
- Double-check your Supabase query to ensure it is correctly filtering the data based on the
```
customer.name
```
  customer.name
```
customer.name
```
  customer.name
  field. Use the
```
ilike
```
  ilike
```
ilike
```
  ilike
  function for case-insensitive matching.

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Ensure this matches your table structure
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Ensure this matches your table structure
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Ensure this matches your table structure
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

   const fetchFilteredData = async (searchValue: string) => {
       const { data, error } = await supabase
           .from('your_table_name')
           .select('*, customer:customer_id(name)') // Ensure this matches your table structure
           .ilike('customer.name', `%${searchValue}%`); // Use ilike for case-insensitive filtering

       if (error) {
           console.error('Error fetching data:', error);
           return [];
       }

       return data;
   };

**Check Data Structure**:
- Ensure that the data structure returned by Supabase includes the
```
customer.name
```
  customer.name
```
customer.name
```
  customer.name
  field and that it is correctly populated. Use tools like Postman or browser developer tools to inspect the API response.
**Update State with Filtered Data**:
- Use React state to store only the filtered data and ensure that your component renders this data.

```typescript
import React, { useState } from 'react';

const MyComponent = () => {
const [filteredData, setFilteredData] = useState([]);

const handleSearch = async (searchValue: string) => {
const data = await fetchFilteredData(searchValue);
setFilteredData(data);
};

### Additional Tips

- **Debugging**: Add console logs in the

fetchFilteredData` function to verify the data being returned and ensure it matches your filter criteria.

Backend Logic: If the issue persists, review the backend logic to ensure it supports the filtering operations you are performing.

By following these steps, you should be able to filter out irrelevant results and display only the data that matches your search criteria. If you continue to experience issues, consider reviewing the Supabase documentation (https://supabase.io/docs) for more insights into querying and filtering data.

To customize the action of a delete button in a view list using refine, you can override the default behavior by providing your own function to handle the delete action. Here’s how you can achieve this:

Steps to Customize the Delete Button Action

**Use the `DeleteButton` Component**:
- The
```
DeleteButton
```
  DeleteButton
```
DeleteButton
```
  DeleteButton
  component can be customized by passing a custom
```
onClick
```
```
onClick
```
  handler.
**Implement Custom Delete Logic**:
- You can implement your own logic for the delete action by using the
```
useDelete
```
  useDelete
```
useDelete
```
  useDelete
  hook from
```
@refinedev/core
```
```
@refinedev/core
```
  .

### Example Code

Here’s an example of how you can customize the delete action in a list view:

``typescript
import React from "react";
import { useTable, useDelete } from "@refinedev/core";
import { Table, Button } from "antd";

const PostList: React.FC = () => {
    const { tableProps } = useTable();
    const { mutate } = useDelete();

    const handleDelete = (id: number) => {
        // Custom delete logic
        mutate(
            {
                resource: "posts",
                id,
            },
            {
                onSuccess: () => {
                    // Custom success handling
                    console.log(

``typescript
import React from "react";
import { useTable, useDelete } from "@refinedev/core";
import { Table, Button } from "antd";

const PostList: React.FC = () => {
    const { tableProps } = useTable();
    const { mutate } = useDelete();

    const handleDelete = (id: number) => {
        // Custom delete logic
        mutate(
            {
                resource: "posts",
                id,
            },
            {
                onSuccess: () => {
                    // Custom success handling
                    console.log(

``typescript
import React from "react";
import { useTable, useDelete } from "@refinedev/core";
import { Table, Button } from "antd";

const PostList: React.FC = () => {
    const { tableProps } = useTable();
    const { mutate } = useDelete();

    const handleDelete = (id: number) => {
        // Custom delete logic
        mutate(
            {
                resource: "posts",
                id,
            },
            {
                onSuccess: () => {
                    // Custom success handling
                    console.log(

``typescript
import React from "react";
import { useTable, useDelete } from "@refinedev/core";
import { Table, Button } from "antd";

const PostList: React.FC = () => {
    const { tableProps } = useTable();
    const { mutate } = useDelete();

    const handleDelete = (id: number) => {
        // Custom delete logic
        mutate(
            {
                resource: "posts",
                id,
            },
            {
                onSuccess: () => {
                    // Custom success handling
                    console.log(

Post with ID ${id} deleted successfully.`);
},
onError: (error) => {
// Custom error handling
console.error("Error deleting post:", error);
},
}
);
};
