redux-form - 带有 FieldArray 组件的 asyncBlurFields [英] redux-form - asyncBlurFields with FieldArray Component

问题描述

我想知道如何在 FieldArray 内的 Field 组件上触发异步验证.我有类似的东西:

class MyForm 扩展组件 {构造函数(道具){超级(道具)}使成为() {const { handleSubmit } = this.props返回 (<form onSubmit={handleSubmit}><字段名称=名称"类型=文本"组件={RenderInputField}/><字段数组名称=爱好"组件={渲染爱好}/></表单>)}}MyFormBase = reduxForm ({表格:'我的表格'，证实，异步验证，asyncBlurFields: ['name', 'hobbies.hobby']})(MyFormBase)

使用 RenderHobbies 作为:

const RenderHobbies = ({fields}) =>(<div>{fields.map((hobby, index) => ({<字段name={`${hobby}.hobby`}组件={RenderInputField}/>}))}

)导出默认 RenderHobbies

这不起作用.异步验证将针对模糊上的名称"而不是hobbies.hobby"触发.正确的语法是什么?

解决方案

我正在寻找的语法是:

asyncBlurFields: ['hobbies[].hobby']

很简单，我只是在文档中找不到它.我通过 this thread

找到了它

I'm wondering how to get async validation to trigger on a Field component inside of a FieldArray. I have something like:

class MyForm extends Component {
  constructor(props) {
    super(props)

  }

  render() {
    const { handleSubmit } = this.props

    return (
      <form onSubmit={handleSubmit}>  
        <Field
          name="name"
          type="text"
          component={RenderInputField}
        />
        <FieldArray
          name="hobbies"
          component={RenderHobbies}
        />
      </form>
    )
  }
}

MyFormBase = reduxForm ({
  form: 'MyForm',
  validate,
  asyncValidate,
  asyncBlurFields: ['name', 'hobbies.hobby']
})(MyFormBase)

With RenderHobbies as:

const RenderHobbies = ({fields}) => (
  <div>
    {fields.map((hobby, index) => ({
      <Field
        name={`${hobby}.hobby`}
        component={RenderInputField}
      />
    }))}
  </div>
)

export default RenderHobbies

This doesn't work. async validation will fire for "name" on blur but not "hobbies.hobby". What would the correct syntax for that be?

解决方案

The syntax I was looking for was:

asyncBlurFields: ['hobbies[].hobby']

Pretty simple, I just couldn't find it anywhere in the docs. I found it by going through this thread
