所以我尝试加载一个预先填充了我商店值的Redux表单。但是,除了null
之外,我无法获得任何回报。现在已经在这几个小时了,并且已经阅读了几个尝试不同事物的SO示例,并认为我只是在墙上。
遵循此Redux Form Initializing from State example
有一个父组件正在呈现作为表单的子组件。为了简洁起见,将最少的代码放在一起并尽可能使名称通用。一切都很好,但我认为问题依赖于没有正确连接到我的商店。或者我应该只是在componentWillMount
?
父组件:
import React, { Component } from 'react';
import { connect } from 'react-redux';
import { fetchUser } from '../actions/usersActions';
import ChildForm from './ChildForm.jsx'
@connect((store) => {
return{
user: store.users.user
}
})
export default class Parent extends Component{
componentWillMount(){
this.props.dispatch(fetchUser(this.props.match.params.id))
}
submit = (values) => {//do some stuff}
render(){
return(
<ChildForm onSubmit={this.submit} />
);
}
}
ChildForm:
import React, { Component } from 'react';
import { connect } from 'react-redux';
import { Field, reduxForm } from 'redux-form';
import { user } from './reducers/usersReducer.js';
class ChildForm extends Component{
render(){
console.log('FORM STATE >>>>>>>>>>', this.state); //Returns NULL
const { handleSubmit } = this.props;
return(
<form onSubmit={handleSubmit}>
<div>
<label htmlFor="firstName">First Name</label>
<Field name="first_name" component="input" type="text"/>
</div>
<button type="submit">Submit</button>
</form>
);
}
}
ChildForm = reduxForm({
form: 'childForm',
enableReinitialize : true // I found this in another SO Example
})(ChildForm);
ChildForm = connect(
state => ({
user: state.user,
initialValues: state.user
}),
{ fetchUser }
)(ChildForm)
export default ChildForm;
usersReducer.js
export default function reducer(state={
user: {},
}, action){
switch (action.type){
case "FETCH_USER_FULFILLED":{
return{
...state,
user: action.payload
}
}
}
return state;
}
所以这就是我现在所处的位置。可以获取页面,表单和提交所有工作。但是,我似乎无法弄清楚如何将我的Store值输出到表单字段中。任何帮助将不胜感激。

看起来所有内容都已正确连线,但我没有在商店中提取正确的对象。
ChildForm = connect(
state => ({
initialValues: state.users.user
}),
{ fetchUser }
)(ChildForm)
......总是很少
