useAutocomplete loading

How can I set a useEffect hook that runs once the useAutocomplete axios request completes.

Hi @.chasel. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The useEffect hook in React allows you to perform side effects in function components. It is a combination of componentDidMount, componentDidUpdate, and componentWillUnmount lifecycle methods from class components. It runs asynchronously and is commonly used to make API requests. Here is a basic syntax of useEffect:

import React, { useEffect } from 'react';  
  
function MyComponent() {  
 useEffect(() => {  
 // Side effect logic goes here  
 console.log('Component rendered!');  
 // Cleanup function (optional)  
 return () => {  
 console.log('Component unmounted!');  
 };  
 }, []); // Empty dependencies array, runs only on mount  
 return (  
 <div>  
 {/* Component JSX */}  
 </div>  
 );  
}

import React, { useEffect } from 'react';  
  
function MyComponent() {  
 useEffect(() => {  
 // Side effect logic goes here  
 console.log('Component rendered!');  
 // Cleanup function (optional)  
 return () => {  
 console.log('Component unmounted!');  
 };  
 }, []); // Empty dependencies array, runs only on mount  
 return (  
 <div>  
 {/* Component JSX */}  
 </div>  
 );  
}

The useEffect hook runs once the component is fully loaded initially, and then every time there's a change in the component's state. If you want it to run once the useAutocomplete axios request completes, you would need to set a state variable when the axios request completes and include that state variable in the dependency array of the useEffect hook. However, the provided extracts do not include a specific example of using useEffect with useAutocomplete in refine. For more detailed information, you may want to refer to the refine documentation (https://refine.dev/docs) or the React documentation on useEffect (https://reactjs.org/docs/hooks-effect.html). Please note that the useAutocomplete hook in refine is used to manage Material UI <Autocomplete> component when records in a resource need to be used as select options. It uses the useList hook for fetching data. You can find more details about useAutocomplete in the refine documentation (https://refine.dev/docs/api-reference/mui/hooks/useAutocomplete/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I am getting a uncontrolled to controlled error in my code but followed the controlled autocomplete steps in the docs.

Let me check the knowledge base for you. One moment! :books: ---------------------- The "uncontrolled to controlled" error typically occurs when you switch an input field from being uncontrolled (no value prop) to controlled (having a value prop). This is a common issue in React and it's important to ensure that your input fields are either fully controlled or uncontrolled. In the context of the useAutocomplete hook in refine, it's used to manage Material UI <Autocomplete> component. Here's a basic usage example from the provided extracts:

import { useAutocomplete } from "@refinedev/mui";  
import { Autocomplete, TextField } from "@mui/material";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { autocompleteProps } = useAutocomplete<ICategory>({  
 resource: "categories",  
 });  
  
 return (  
 <Autocomplete  
 {...autocompleteProps}  
 getOptionLabel={(item) => item.title}  
 isOptionEqualToValue={(option, value) =>  
 value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()  
 }  
 placeholder="Select a category"  
 renderInput={(params) => (  
 <TextField  
 {...params}  
 label="Category"  
 margin="normal"  
 variant="outlined"  
 required  
 />  
 )}  
 />  
 );  
};

import { useAutocomplete } from "@refinedev/mui";  
import { Autocomplete, TextField } from "@mui/material";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { autocompleteProps } = useAutocomplete<ICategory>({  
 resource: "categories",  
 });  
  
 return (  
 <Autocomplete  
 {...autocompleteProps}  
 getOptionLabel={(item) => item.title}  
 isOptionEqualToValue={(option, value) =>  
 value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()  
 }  
 placeholder="Select a category"  
 renderInput={(params) => (  
 <TextField  
 {...params}  
 label="Category"  
 margin="normal"  
 variant="outlined"  
 required  
 />  
 )}  
 />  
 );  
};

In this example, the Autocomplete component is controlled by the autocompleteProps provided by the useAutocomplete hook. If you're getting a "uncontrolled to controlled" error, it might be because you're trying to control the value of the Autocomplete component manually while also using autocompleteProps from useAutocomplete. You should ensure that the Autocomplete component is fully controlled by autocompleteProps and not manually setting or changing the value prop. If you're still facing issues, it would be helpful to review the refine documentation (https://refine.dev/docs/api-reference/mui/hooks/useAutocomplete/) and ensure that your implementation aligns with the examples and guidelines provided. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai That code is not requiring the user to select an input though. For example in my code here:

<Autocomplete
                    {...patientAutocompleteProps}
                    getOptionLabel={(item) => item.name}
                    isOptionEqualToValue={(option, value) =>
                        option?.patient_id?.toString() === value?.patient_id?.toString()
                    }
                    placeholder="Select a category"
                    renderInput={(params) => (
                        <TextField
                            {...params}
                            label="Category"
                            margin="normal"
                            variant="outlined"
                            required
                        />
                    )}

<Autocomplete
                    {...patientAutocompleteProps}
                    getOptionLabel={(item) => item.name}
                    isOptionEqualToValue={(option, value) =>
                        option?.patient_id?.toString() === value?.patient_id?.toString()
                    }
                    placeholder="Select a category"
                    renderInput={(params) => (
                        <TextField
                            {...params}
                            label="Category"
                            margin="normal"
                            variant="outlined"
                            required
                        />
                    )}

A user does not have to select an option before submitting the form which is causing errors

kapa.ai•13mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The required prop in the TextField component of Material UI doesn't prevent form submission. It only provides a visual indication that the field is required. If you want to prevent form submission until a user selects an option, you need to implement form validation. Unfortunately, the provided extracts do not include specific examples or guidelines on how to implement form validation with the useAutocomplete hook in refine. However, you can use libraries like react-hook-form or formik to manage your form state and validation. In the context of react-hook-form, you can use the Controller component to wrap your Autocomplete component and use the rules prop to make the field required. Here's a basic example:

import { Controller } from 'react-hook-form';

// Inside your component
const { handleSubmit, control, formState: { errors } } = useForm();

return (
  <form onSubmit={handleSubmit(onSubmit)}>
    <Controller
      name="category"
      control={control}
      rules={{ required: 'Category is required' }}
      render={({ field }) => (
        <Autocomplete
          {...field}
          {...patientAutocompleteProps}
          getOptionLabel={(item) => item.name}
          isOptionEqualToValue={(option, value) =>
            option?.patient_id?.toString() === value?.patient_id?.toString()
          }
          placeholder="Select a category"
          renderInput={(params) => (
            <TextField
              {...params}
              label="Category"
              margin="normal"
              variant="outlined"
              error={!!errors.category}
              helperText={errors.category?.message}
              required
            />
          )}
        />
      )}
    />
    <button type="submit">Submit</button>
  </form>
);

import { Controller } from 'react-hook-form';

// Inside your component
const { handleSubmit, control, formState: { errors } } = useForm();

return (
  <form onSubmit={handleSubmit(onSubmit)}>
    <Controller
      name="category"
      control={control}
      rules={{ required: 'Category is required' }}
      render={({ field }) => (
        <Autocomplete
          {...field}
          {...patientAutocompleteProps}
          getOptionLabel={(item) => item.name}
          isOptionEqualToValue={(option, value) =>
            option?.patient_id?.toString() === value?.patient_id?.toString()
          }
          placeholder="Select a category"
          renderInput={(params) => (
            <TextField
              {...params}
              label="Category"
              margin="normal"
              variant="outlined"
              error={!!errors.category}
              helperText={errors.category?.message}
              required
            />
          )}
        />
      )}
    />
    <button type="submit">Submit</button>
  </form>
);

In this example, the rules prop is used to make the field required and display an error message when the field is not filled. The error and helperText props in the TextField component are used to display the error state and message. Please note that this is a general example and might need adjustments based on your exact use case and setup. For more detailed information, you may want to refer to the react-hook-form documentation (https://react-hook-form.com/api/useform/controller) or the refine documentation (https://refine.dev/docs). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
