How watch any changes of payload in useForm?

14 Replies

Hi @tingadev. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To watch changes in the form payload when using useForm in refine, you can utilize the watch function provided by React Hook Form. Here's how you can do it: 1. First, destructure the watch function from the useForm hook:

const { watch } = useForm();

const { watch } = useForm();

2. Then, you can use the watch function to observe changes in specific fields or the entire form:

// Watch the entire form
const formValues = watch();

// Watch specific fields
const specificField = watch("fieldName");

// Watch the entire form
const formValues = watch();

// Watch specific fields
const specificField = watch("fieldName");

The watch function allows you to subscribe to form data changes. It will trigger re-renders when the watched values change, similar to controlled components in React. Here's an example of how you might use it:

import { useForm } from "@refinedev/react-hook-form";

const MyComponent = () => {
  const { watch } = useForm();
  
  // Watch the entire form
  const formValues = watch();
  
  console.log(formValues); // This will log the current form values whenever they change

  return (
    // Your form JSX here
  );
};

import { useForm } from "@refinedev/react-hook-form";

const MyComponent = () => {
  const { watch } = useForm();
  
  // Watch the entire form
  const formValues = watch();
  
  console.log(formValues); // This will log the current form values whenever they change

  return (
    // Your form JSX here
  );
};

It's important to note that using watch will cause re-renders, so use it judiciously, especially with large forms. For more detailed information on using watch with React Hook Form in refine, you can refer to the React Hook Form blog post (https://refine.dev/blog/react-hook-form/#watching-form-fields-in-react-hook-form-with-watch). React Hook Form Documentation (https://refine.dev/blog/react-hook-form/#how-react-hook-form-works) also provides more context on how React Hook Form works within refine. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

How can I watch any fiels form after edit action? How can I watch any fiels form after edit action? @kapa.ai

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To watch form fields after an edit action in refine using useForm, you can utilize the watch function provided by React Hook Form. Here's how you can do it: 1. First, make sure you're using the useForm hook from @refinedev/react-hook-form:

import { useForm } from "@refinedev/react-hook-form";

import { useForm } from "@refinedev/react-hook-form";

2. When initializing useForm, specify the edit action and resource:

const {
  refineCore: { onFinish, formLoading, queryResult },
  register,
  handleSubmit,
  watch
} = useForm<IProduct, HttpError, FormValues>({
  refineCoreProps: {
    resource: "products",
    action: "edit",
    id: 123, // The ID of the record being edited
  },
});

const {
  refineCore: { onFinish, formLoading, queryResult },
  register,
  handleSubmit,
  watch
} = useForm<IProduct, HttpError, FormValues>({
  refineCoreProps: {
    resource: "products",
    action: "edit",
    id: 123, // The ID of the record being edited
  },
});

3. Now you can use the watch function to observe changes in specific fields or the entire form:

// Watch the entire form
const formValues = watch();

// Watch specific fields
const nameField = watch("name");
const materialField = watch("material");

// Watch the entire form
const formValues = watch();

// Watch specific fields
const nameField = watch("name");
const materialField = watch("material");

4. You can use these watched values in your component to react to changes:

useEffect(() => {
  console.log("Form values changed:", formValues);
}, [formValues]);

useEffect(() => {
  console.log("Name changed:", nameField);
}, [nameField]);

useEffect(() => {
  console.log("Form values changed:", formValues);
}, [formValues]);

useEffect(() => {
  console.log("Name changed:", nameField);
}, [nameField]);

Here's a more complete example:

import { useForm } from "@refinedev/react-hook-form";
import { useEffect } from "react";

const EditPage = () => {
  const {
    refineCore: { onFinish, formLoading, queryResult },
    register,
    handleSubmit,
    watch
  } = useForm<IProduct, HttpError, FormValues>({
    refineCoreProps: {
      resource: "products",
      action: "edit",
      id: 123,
    },
  });

  const formValues = watch();

  useEffect(() => {
    console.log("Form values changed:", formValues);
  }, [formValues]);
return (
    <form onSubmit={handleSubmit(onFinish)}>
      <input {...register("name")} />
      <input {...register("material")} />
      <button type="submit">Submit</button>
    </form>
  );
};

import { useForm } from "@refinedev/react-hook-form";
import { useEffect } from "react";

const EditPage = () => {
  const {
    refineCore: { onFinish, formLoading, queryResult },
    register,
    handleSubmit,
    watch
  } = useForm<IProduct, HttpError, FormValues>({
    refineCoreProps: {
      resource: "products",
      action: "edit",
      id: 123,
    },
  });

  const formValues = watch();

  useEffect(() => {
    console.log("Form values changed:", formValues);
  }, [formValues]);
return (
    <form onSubmit={handleSubmit(onFinish)}>
      <input {...register("name")} />
      <input {...register("material")} />
      <button type="submit">Submit</button>
    </form>
  );
};

This approach allows you to watch for changes in your form fields after the edit action has loaded the initial data. The watch function will trigger re-renders when the watched values change, allowing you to react to these changes in your component. For more detailed information on using useForm with React Hook Form in refine, you can refer to the React Hook Form useForm documentation (https://refine.dev/docs/packages/react-hook-form/use-form/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Why are s added after sidebar resource names like this? How can I remove that? I didn't add it like this.

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- The addition of "s" to resource names in the sidebar is due to Refine's default behavior of pluralizing resource names. This is done to make the UI more user-friendly and consistent with common naming conventions. However, if you want to prevent this pluralization, you have a few options: 1. You can use the textTransformers option in the <Refine> component to customize how resource names are displayed. Here's how you can disable the pluralization:

const App = () => (
  <Refine
    // ...
    options={{
      textTransformers: {
        plural: (text) => text,
      },
    }}
  />
);

const App = () => (
  <Refine
    // ...
    options={{
      textTransformers: {
        plural: (text) => text,
      },
    }}
  />
);

This will prevent Refine from pluralizing the resource names in the sidebar as documented here (https://refine.dev/docs/core/refine-component/#texttransformers). 2. Alternatively, you can provide a custom label in the meta property of your resource definition. This label will be used instead of the automatically pluralized resource name:

resources={[
  {
    name: "post",
    list: "/posts",
    meta: {
      label: "Post", // This will be used in the sidebar instead of "Posts"
    },
  },
]}

resources={[
  {
    name: "post",
    list: "/posts",
    meta: {
      label: "Post", // This will be used in the sidebar instead of "Posts"
    },
  },
]}

This approach is mentioned in the FAQ section of the Refine documentation (https://refine.dev/docs/guides-concepts/faq/#how-to-hide-items-from-the-sider-component). 3. If you're using a custom Sider component, you can also handle the resource names manually without relying on Refine's automatic pluralization. By using one of these methods, you can control how resource names appear in your sidebar and prevent the automatic addition of "s" to your resource names. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to create a searchbar to filter the table content

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To create a searchbar to filter table content in refine, you can use the useTable hook along with a search form. Here's how you can implement it: 1. First, import the necessary components and hooks:

import { useTable } from "@refinedev/antd";
import { Form, Input, Button, Table } from "antd";

import { useTable } from "@refinedev/antd";
import { Form, Input, Button, Table } from "antd";

2. In your component, use the useTable hook and destructure the tableProps and searchFormProps:

const { tableProps, searchFormProps } = useTable({
  resource: "your-resource",
  onSearch: (values) => {
    return [
      {
        field: "name",
        operator: "contains",
        value: values.name,
      },
    ];
  },
});

const { tableProps, searchFormProps } = useTable({
  resource: "your-resource",
  onSearch: (values) => {
    return [
      {
        field: "name",
        operator: "contains",
        value: values.name,
      },
    ];
  },
});

3. Create a search form using Ant Design components:

<Form {...searchFormProps} layout="inline">
  <Form.Item name="name">
    <Input placeholder="Search by name" />
  </Form.Item>
  <Form.Item>
    <Button htmlType="submit">Search</Button>
  </Form.Item>
</Form>

<Form {...searchFormProps} layout="inline">
  <Form.Item name="name">
    <Input placeholder="Search by name" />
  </Form.Item>
  <Form.Item>
    <Button htmlType="submit">Search</Button>
  </Form.Item>
</Form>

4. Render your table using the tableProps:

<Table {...tableProps} columns={yourColumns} />

<Table {...tableProps} columns={yourColumns} />

Here's a complete example:

import React from "react";
import { useTable } from "@refinedev/antd";
import { Form, Input, Button, Table } from "antd";

export const ProductTable: React.FC = () => {
  const { tableProps, searchFormProps } = useTable({
    resource: "products",
    onSearch: (values) => {
      return [
        {
          field: "name",
          operator: "contains",
          value: values.name,
        },
      ];
    },
  });

  return (
    <div>
      <Form {...searchFormProps} layout="inline">
        <Form.Item name="name">
          <Input placeholder="Search by name" />
        </Form.Item>
        <Form.Item>
          <Button htmlType="submit">Search</Button>
        </Form.Item>
      </Form>
      <Table {...tableProps} columns={yourColumns} />
    </div>
  );
};

import React from "react";
import { useTable } from "@refinedev/antd";
import { Form, Input, Button, Table } from "antd";

export const ProductTable: React.FC = () => {
  const { tableProps, searchFormProps } = useTable({
    resource: "products",
    onSearch: (values) => {
      return [
        {
          field: "name",
          operator: "contains",
          value: values.name,
        },
      ];
    },
  });

  return (
    <div>
      <Form {...searchFormProps} layout="inline">
        <Form.Item name="name">
          <Input placeholder="Search by name" />
        </Form.Item>
        <Form.Item>
          <Button htmlType="submit">Search</Button>
        </Form.Item>
      </Form>
      <Table {...tableProps} columns={yourColumns} />
    </div>
  );
};

This implementation creates a search bar that filters the table content based on the "name" field. When the user enters a search term and submits the form, the onSearch function is called, which returns a filter object that refine uses to fetch the filtered data. You can customize the search fields and filter logic according to your needs. For more detailed information and examples, you can refer to the refine documentation on table search (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-table/#search). Open table-antd-table-filter example from refine (https://github.com/refinedev/refine/blob/master/examples/table-antd-table-filter/README.md) provides a complete example of implementing table filtering with a search bar. Remember to adjust the resource name, column definitions, and search fields according to your specific use case. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai create search filter for this code to filter users: import React from "react"; import { DeleteButton, EditButton, List, ShowButton, useTable, } from "@refinedev/antd"; import type { BaseRecord } from "@refinedev/core"; import { Space, Table, Input, Row, Col } from "antd"; const { Column } = Table; const { Search } = Input; export const UsersList = () => { const { tableProps, setFilters } = useTable({ syncWithLocation: true, onSearch: (searchText) => [ { field: "name", operator: "contains", value: searchText, }, ], }); return ( <div> <List> <Row style={{ marginBottom: 16 }}> <Col span={12}> <Search placeholder="Search by name or email" enterButton onSearch={handleSearch} style={{ width: 300 }} /> </Col> </Row> <Table {...tableProps} rowKey="id"> <Column dataIndex="name" title="Name" /> <Column dataIndex="phonenumber" title="Phone Number" /> <Column dataIndex="email" title="Email" /> <Column dataIndex="role" title="Role" /> <Column title="Actions" dataIndex="actions" render={(, record: BaseRecord) => ( <Space> <EditButton hideText size="small" recordItemId={record.id} /> <ShowButton hideText size="small" recordItemId={record.id} /> <DeleteButton hideText size="small" recordItemId={record.id} /> </Space> )} /> </Table> </List> </div> ); };

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To create a search filter for the given code to filter users, you can modify the existing UsersList component to use the setFilters function from useTable hook. Here's how you can implement it: 1. First, let's modify the useTable hook to include both name and email in the search:

const { tableProps, setFilters } = useTable({
  syncWithLocation: true,
  onSearch: (params) => [
    {
      operator: "or",
      value: [
        { field: "name", operator: "contains", value: params.q },
        { field: "email", operator: "contains", value: params.q },
      ],
    },
  ],
});

const { tableProps, setFilters } = useTable({
  syncWithLocation: true,
  onSearch: (params) => [
    {
      operator: "or",
      value: [
        { field: "name", operator: "contains", value: params.q },
        { field: "email", operator: "contains", value: params.q },
      ],
    },
  ],
});

2. Now, let's create a handleSearch function to use setFilters:

const handleSearch = (value: string) => {
  setFilters([{ field: "q", operator: "eq", value }]);
};

const handleSearch = (value: string) => {
  setFilters([{ field: "q", operator: "eq", value }]);
};

3. Finally, update the Search component to use the handleSearch function:

<Search
  placeholder="Search by name or email"
  enterButton
  onSearch={handleSearch}
  style={{ width: 300 }}
/>

<Search
  placeholder="Search by name or email"
  enterButton
  onSearch={handleSearch}
  style={{ width: 300 }}
/>

Here's the complete updated code:

import React from "react";
import {
  DeleteButton,
  EditButton,
  List,
  ShowButton,
  useTable,
} from "@refinedev/antd";
import type { BaseRecord } from "@refinedev/core";
import { Space, Table, Input, Row, Col } from "antd";

const { Column } = Table;
const { Search } = Input;

export const UsersList = () => {
  const { tableProps, setFilters } = useTable({
    syncWithLocation: true,
    onSearch: (params) => [
      {
        operator: "or",
        value: [
          { field: "name", operator: "contains", value: params.q },
          { field: "email", operator: "contains", value: params.q },
        ],
      },
    ],
  });

  const handleSearch = (value: string) => {
    setFilters([{ field: "q", operator: "eq", value }]);
  };
return (
    <div>
      <List>
        <Row style={{ marginBottom: 16 }}>
          <Col span={12}>
            <Search
              placeholder="Search by name or email"
              enterButton
              onSearch={handleSearch}
              style={{ width: 300 }}
            />
          </Col>
        </Row>
        <Table {...tableProps} rowKey="id">

                <ShowButton hideText size="small" recordItemId={record.id} />
                <DeleteButton hideText size="small" recordItemId={record.id} />
              </Space>
            )}
          />
        </Table>
      </List>
    </div>
  );
};

import React from "react";
import {
  DeleteButton,
  EditButton,

          { field: "email", operator: "contains", value: params.q },
        ],
      },
    ],
  });

  const handleSearch = (value: string) => {
    setFilters([{ field: "q", operator: "eq", value }]);
  };
return (
    <div>
      <List>

              enterButton
              onSearch={handleSearch}
              style={{ width: 300 }}
            />
          </Col>
        </Row>
        <Table {...tableProps} rowKey="id">
          <Column dataIndex="name" title="Name" />
          <Column dataIndex="phone_number" title="Phone Number" />
          <Column dataIndex="email" title="Email" />
          <Column dataIndex="role" title="Role" />
          <Column
            title="Actions"
            dataIndex="actions"
            render={(_, record: BaseRecord) => (
              <Space>
                <EditButton hideText size="small" recordItemId={record.id} />
                <ShowButton hideText size="small" recordItemId={record.id} />
                <DeleteButton hideText size="small" recordItemId={record.id} />
              </Space>
            )}
          />
        </Table>
      </List>
    </div>
  );
};

This implementation creates a search bar that filters the table content based on both the "name" and "email" fields. When the user enters a search term and submits the form, the handleSearch function is called, which uses setFilters to update the table filters. The useTable hook then fetches the filtered data based on these filters. For more information on using filters with useTable, you can refer to the refine documentation on table filtering (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-table/#filtering). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
