I am trying to use a custom Material-UI Autocomplete
component and connect it to react-hook-form
.
TLDR: Need to use MUI Autocomplete with react-hook-form Controller without defaultValue
My custom Autocomplete
component takes an object with the structure {_id:'', name: ''}
it displays the name and returns the _id
when an option is selected. The Autocomplete
works just fine.
<Autocomplete
options={options}
getOptionLabel={option => option.name}
getOptionSelected={(option, value) => option._id === value._id}
onChange={(event, newValue, reason) => {
handler(name, reason === 'clear' ? null : newValue._id);
}}
renderInput={params => <TextField {...params} {...inputProps} />}
/>
In order to make it work with react-hook-form
I've set the setValues
to be the handler for onChange
in the Autocomplete
and manually register the component in an useEffect
as follows
useEffect(() => {
register({ name: "country1" });
},[]);
This works fine but I would like to not have the useEffect
hook and just make use of the register somehow directly.
Next I tried to use the Controller
component from react-hook-form
to proper register the field in the form and not to use the useEffect
hook
<Controller
name="country2"
as={
<Autocomplete
options={options}
getOptionLabel={option => option.name}
getOptionSelected={(option, value) => option._id === value._id}
onChange={(event, newValue, reason) =>
reason === "clear" ? null : newValue._id
}
renderInput={params => (
<TextField {...params} label="Country" />
)}
/>
}
control={control}
/>
I've changed the onChange
in the Autocomplete
component to return the value directly but it doesn't seem to work.
Using inputRef={register}
on the <TextField/>
would not cut it for me because I want to save the _id
and not the name
HERE is a working sandbox with the two cases. The first with useEffect
and setValue
in the Autocomplete
that works. The second my attempt in using Controller
component
Any help is appreciated.

After the comment from Bill with the working sandbox of MUI Autocomplete, I Managed to get a functional result
<Controller
name="country"
as={
<Autocomplete
options={options}
getOptionLabel={option => option.name}
getOptionSelected={(option, value) => option._id === value._id}
renderInput={params => <TextField {...params} label="Country" />}
/>
}
onChange={([, { _id }]) => _id}
control={control}
/>
The only problem is that I get an MUI Error
in the console
- Material-UI: A component is changing the uncontrolled value state of Autocomplete to be controlled.*
I've tried to set an defaultValue
for it but it still behaves like that. Also I would not want to set a default value from the options array due to the fact that these fields in the form are not required.
The updated sandbox HERE
Any help is still very much appreciated

接受的答案(可能)适用于有bug的自动完成版本。我认为bug在那之后的一段时间被修复了,这样解决方案就可以稍微简化了。
在使用react-hook-form和material-ui时,这是非常有用的参考/代码和框:是吗?
从上面的链接,我修改了自动完成的例子:
用法:
control
来自useForm(}
的返回值注意,我将
null
作为defaultValue
传递,因为在我的例子中,这个输入是不需要的。如果你离开defaultValue
,你可能会从material-ui库中得到一些错误。更新日期:
根据Steve在评论中提出的问题,这是我呈现输入的方式,以便它检查错误:
其中
errors
是react-hook-form
的formMethods
的对象:fkaflof62#
所以,我修复了这个问题。但是它揭示了我认为是自动完成中的一个错误。
首先......具体到您的问题,您可以通过向
<Controller>
添加 defaultValue 来消除MUI Error
。但这只是另一轮问题的开始。问题在于,
getOptionLabel
、getOptionSelected
和onChange
的函数有时会传递值(即本例中的_id
),有时会传递选项结构--正如您所期望的那样。下面是我最终想到的代码:

我不知道为什么上面的答案对我不起作用,这里是对我起作用的最简单的代码,我使用
Controller
的render
函数与onChange
根据所选的一个来更改值。vsikbqxv5#
多亏了所有其他的答案,截止到2022年4月15日,我已经能够弄清楚如何让它工作,并在
TextField
组件中呈现标签:在我的例子中,
options
是一个{code: 'US', label: 'United States'}
对象的数组,最大的区别是getOptionLabel
,我想当你打开列表(option
是一个对象),当选项在TextField
中呈现(当选项是一个字符串),以及当没有选择任何东西时,都需要考虑getOptionLabel
。j9per5c46#
我已经使它工作得很好,包括如下所示的多个标签选择器。它将与mui 5和react-hook-form 7工作得很好

代替使用控制器,借助register,setValue的useForm和value,onChange的Autocomplete我们可以达到同样的结果。
