To set initial values for a select component in Refine, you can use the

useSelect

useSelect

hook. This hook sends a request via

useMany

useMany

, gets the data, and marks the default value as selected. Here is an example of how you can use it:

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",  
 defaultValue: 11,  
 });  
  
 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",  
 defaultValue: 11,  
 });  
  
 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",  
 defaultValue: 11,  
 });  
  
 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",  
 defaultValue: 11,  
 });  
  
 return <Select placeholder="Select a category" style={{ width: 300 }} {...selectProps} />;  
};

In this example, the

defaultValue

defaultValue

prop is used to set the initial value of the select component. The

useSelect

useSelect

hook is used with the

resource

resource

prop set to "categories" and the

defaultValue

defaultValue

prop set to 11. This means that the select component will initially display the category with the id of 11.

For more information, refer to the Refine documentation on useSelect (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-select#how-to-ensure-defaultvalue-is-included-in-the-options).

Sorry @yasuaki_jp, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist:

Perhaps try again in 15mins?

should I use defaultValueQueryResult?

The

defaultValueQueryResult

defaultValueQueryResult

defaultValueQueryResult

defaultValueQueryResult is a property returned by the

useSelect

useSelect

hook in Refine. It represents the result of the query of a

defaultValue

defaultValue

record.

However, based on the information provided in the extracts, it's not typically used to set the initial value of a select component. Instead, you would use the

defaultValue

defaultValue

property when calling the

useSelect

useSelect

hook to set the initial value.

Here's an example:

const { selectProps } = useSelect({
  resource: "categories",
  defaultValue: 1, // or [1, 2]
});

const { selectProps } = useSelect({
  resource: "categories",
  defaultValue: 1, // or [1, 2]
});

const { selectProps } = useSelect({
  resource: "categories",
  defaultValue: 1, // or [1, 2]
});

const { selectProps } = useSelect({
  resource: "categories",
  defaultValue: 1, // or [1, 2]
});

In this example, the

defaultValue

defaultValue

is set to 1, which means the select component will initially display the category with the id of 1.

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

I can't see setting default value with "defaultValue" key and value.

To set a default value for a select component in Refine, you can use the

defaultValue

defaultValue

property in the

useSelect

useSelect

hook. This property allows you to set a default value or values for the select component.

Here's an example of how you can use it:

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",  
 defaultValue: 11,  
 });  
  
 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",  
 defaultValue: 11,  
 });  
  
 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",  
 defaultValue: 11,  
 });  
  
 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",  
 defaultValue: 11,  
 });  
  
 return <Select placeholder="Select a category" style={{ width: 300 }} {...selectProps} />;  
};

In this example, the

defaultValue

defaultValue

is set to 11, which means the select component will initially display the category with the id of 11.

If you're facing issues with setting the default value, it could be due to the fact that the

defaultValue

defaultValue

might not be visible among the currently displayed options if the select component has many entries and pagination is required. To prevent this, a separate

useMany

useMany

query is sent to the backend carrying the

defaultValue

defaultValue

and added to the options of the select component, ensuring that the default values are always present in the current array of options.

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

I gave up getFields Instead I will use setState.

Sure, you can use the

setState

setState

setState

setState function to manage your component's state in React. This is a common approach for handling state changes in functional components. Here's a basic example:

import React, { useState } from 'react';

function Example() {
  // Declare a new state variable, which we'll call "count"
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
}

import React, { useState } from 'react';

function Example() {
  // Declare a new state variable, which we'll call "count"
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
}

import React, { useState } from 'react';

function Example() {
  // Declare a new state variable, which we'll call "count"
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
}

import React, { useState } from 'react';

function Example() {
  // Declare a new state variable, which we'll call "count"
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
}

In this example,

useState

useState

is a Hook that allows you to add React state to function components. We're calling it here with the initial state. In our example above, it's 0 because our counter starts from zero. The

setCount

setCount

setCount

setCount function allows us to update the state.

Remember, the

setState

setState

setState

setState function in functional components doesn't merge the old and new state as it does in class components. It replaces the old state with the new one. So if you have multiple state variables, you should call

setState

setState

setState

setState for each one separately.

For more information, you can refer to the React documentation on useState (https://reactjs.org/docs/hooks-state.html).
