To extend CRUD filters in refine, you can utilize the
CrudFilter
and CrudFilters
types. Here’s a step-by-step guide on how to work with and extend these filters:
Understanding CrudFilter
and CrudFilters
1. CrudFilter: This type can be either a LogicalFilter
or a ConditionalFilter
.
Source (https://refine.dev/docs/core/interface-references#crudfilter)
2. CrudFilters: This is an array of 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
type. Here’s an example from a useTable
hook:
Source (https://refine.dev/docs/advanced-tutorials/search/table-search)
Extending Filters for Deep Filtering
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:
This converts to: /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:

@kapa.ai i want to use icontains which is not present in place of
onSearch: (value: any) => {
const { title } = value;
return [
{
field: 'source_name',
operator: 'icontains',
value: title,
},
];
},
how to achieve this
Let me check the knowledge base for you. One moment! :books:
----------------------
To achieve the functionality of using the
icontains
operator, which is not directly available, you can use the contains
operator as a workaround. The contains
operator performs a case-insensitive search by default in many systems. Here’s how you can implement it using the onSearch
function:
Example Code
Explanation
- Operator: The contains
operator is used to perform a case-insensitive search. This is a common approach when icontains
is not available.
- onSearch Function: The 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).
If you have any further questions or need additional customization, feel free to ask!

@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)"
Let me check the knowledge base for you again. One moment! :books:
----------------------
To filter a column with relational data, such as a customer name, using the
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:
Explanation
- Field Path: Use the dot notation (customer.name
) to specify the path to the relational field you want to filter.
- Operator: The 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
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).
If you have any further questions or need additional customization, feel free to ask!

@kapa.ai when i am doing it like this it gives the data but also shows some columns that shouldnt be there with other fileds names and cutomer name as blank why?
Let me check the knowledge base for you again. One moment! :books:
----------------------
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
1. 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.
2. 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
parameter in your query.
3. 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.
4. 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:
- Check Field Paths: Make sure the field paths in your filters and table columns match the API response structure. For example:
- Inspect API Response: Use tools like Postman or browser developer tools to inspect the API response and verify that it includes the expected data.
- Adjust Table Columns: Ensure your table columns are correctly configured to display the data. For example:
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).

@kapa.ai this is my code , whenever i search by customer name i get some extra column in whcih the name is not the same so it's not shown but other records are shown which should not be there only records which contain those should be there
Let me check the knowledge base for you again. One moment! :books:
----------------------
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
1. Ensure Correct Filter Configuration:
- Make sure that the filter is correctly targeting the relational field. For example, if you are filtering by
customer.name
, ensure that the field path is correct and matches the API response structure.
2. Verify API Response:
- Use tools like Postman or browser developer tools to inspect the API response. Ensure that the response includes the customer.name
field and that it is populated correctly.
3. 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.
4. 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.
5. Backend Filtering:
- If the filtering is done server-side, ensure that the backend logic correctly implements the contains
operator and returns only the matching records.
Additional Considerations
- 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).

@kapa.ai it's not working how can i handle this column filtering manualy
Let me check the knowledge base for you again. One moment! :books:
----------------------
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
1. Fetch Data Manually:
- Use the Supabase client to fetch data manually, applying your filter logic directly in the query.
2. Update State with Filtered Data:
- Once you have fetched the data, update your component’s state to reflect the filtered results.
3. Render the Filtered Data:
- Use the filtered data to render your table or list component.
Explanation
- Supabase Query: The
ilike
function is used for case-insensitive filtering, which is similar to the 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.

@kapa.ai i want to customise the action of delete button in the view list how do i do that
Let me check the knowledge base for you again. One moment! :books:
----------------------
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
1. Use the
DeleteButton
Component:
- The DeleteButton
component can be customized by passing a custom onClick
handler.
2. Implement Custom Delete Logic:
- You can implement your own logic for the delete action by using the useDelete
hook from @refinedev/core
.
Example Code
Here’s an example of how you can customize the delete action in a list view:
Explanation
- Custom handleDelete
Function: This function uses the useDelete
hook to perform the delete operation. You can add custom logic for success and error handling within this function.
- Button Component: The Button
component from Ant Design is used to trigger the custom delete logic. You can replace this with any button component you prefer.
- Table Configuration: The Table
component is configured to render the delete button in the "Actions" column, allowing you to customize the action for each row.
By following this approach, you can fully customize the delete action in your list view to suit your application's requirements. If you need further customization, you can refer to the useDelete documentation (https://refine.dev/docs/data/hooks/use-delete/) for more details.
