当我使用 redux-form 5.3.1 时，我能够访问我的动作创建者。但由于我需要 Material-UI，我将其更新为 6.0.0-rc.3。

从 5.3.1 到 6.0.0 的变化：

  • 从 render() 中删除的字段：

const { handleSubmit, fields: { email, password, passwordConfirm }} = this.props;

  • 从输入中删除了错误验证：

{email.touched && email.error && <div className="error">{email.error}</div>}

  • 从导出默认值中删除了字段数组：

export default reduxForm({ form: 'signup', fields: ['email', 'password', 'passwordConfirm'], validate }, mapStateToProps, actions)(Signup);

  • 为 Material-UI 组件添加了包装器：

import { renderTextField, renderCheckbox, renderSelectField, renderDatePicker } from '../material-ui-wrapper';

代码：

1 - console.log(this.props) 不记录任何操作创建者- 应该记录 signupUser 函数

'use strict';
import React, { Component } from 'react';
import { reduxForm, Field } from 'redux-form';
import * as actions from '../../actions';

import { renderTextField } from '../material-ui-wrapper';

import {Card, CardActions, CardHeader, CardText} from 'material-ui/Card';
import FlatButton from 'material-ui/FlatButton';

class Signup extends Component {
  handleFormSubmit(formProps) {
    console.log(this.props);
    this.props.signupUser(formProps);
  }

  renderAlert() {
    if (this.props.errorMessage) {
      return (
        <div className="error">
          {this.props.errorMessage}
        </div>
      );
    }
  }

  render() {
    const { handleSubmit, pristine, submitting } = this.props;
    return (
      <form id="form" onSubmit={handleSubmit(this.handleFormSubmit.bind(this))}>
        <Card>
          <CardHeader title="Cadastre-se"/>
          <CardText>
            <Field name="email" component={renderTextField} label={"Email"} fieldType="text"/>
            <Field name="password" component={renderTextField} label={"Senha"} fieldType="password"/>
            <Field name="passwordConfirm" component={renderTextField} label={"Confirmação de senha"} fieldType="password"/>
            {this.renderAlert()}
          </CardText>
          <CardActions>
            <FlatButton type="submit" label="Criar!"/>
          </CardActions>
        </Card>
      </form>
    );
  }
}

function validate(formProps) {
  const errors = {};

  if (!formProps.email || !/^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i.test(formProps.email)) {
    errors.email = 'Por favor, informe um email válido';
  }

  if (formProps.password !== formProps.passwordConfirm) {
    errors.password = 'Senhas devem ser iguais.';
  }

  if (!formProps.password) {
    errors.password = 'Por favor, informe uma senha.';
  }

  if (!formProps.passwordConfirm) {
    errors.passwordConfirm = 'Por favor, confirme a sua senha.';
  }

  return errors;
}

function mapStateToProps(state) {
  return { errorMessage: state.auth.error };
}

export default reduxForm({
  form: 'signup',
  validate
}, mapStateToProps, actions)(Signup);

编辑

改变：

export default reduxForm({ form: 'signup', validate }, mapStateToProps, actions)(Signup);

至：

Signup = reduxForm({ form: 'signup', validate })(Signup); export default Signup = connect(mapStateToProps, actions)(Signup);

它奏效了。这是解决此问题的最正确方法吗？

代替：

export default reduxForm({
  form: 'signup',
  validate
}, mapStateToProps, actions)(Signup);

利用：

Signup = reduxForm({
form: 'signup',
validate})(Signup);

export default Signup = connect(mapStateToProps, actions)(Signup);

PS：可能是一个解决方法

您可以使用 compose 如下

import { compose } from 'redux'
....
export default compose(
    reduxForm({
      form: 'survey',
    }),
    connect(mapStateToProps, actions)
)(Signup)

要将这些值放入您的 redux-form-decorated 组件中，您需要自己 connect() 到 Redux 状态，并将数据缩减器映射到 initialValues 属性。

您可以使用构造函数将方法与现有道具绑定。你不需要传递动作和初始状态。

class Signup extends Component {

  constructor(props) {
     super(props);
     this.handleSubmit = this.handleSubmit.bind(this)
   }

   handleSubmit(formProps) {
     console.log(this.props);
     this.props.signupUser(formProps);
  }
  render() {

  const { handleSubmit, pristine, submitting } = this.props;

  return (

  <form id="form" onSubmit={this.handleFormSubmit}>
    <Card>
      <CardHeader title="Cadastre-se"/>
      <CardText>
        <Field name="email" component={renderTextField} label={"Email"} fieldType="text"/>
        <Field name="password" component={renderTextField} label={"Senha"} fieldType="password"/>
        <Field name="passwordConfirm" component={renderTextField} label={"Confirmação de senha"} fieldType="password"/>
       </CardText>
        <CardActions>
          <FlatButton type="submit" label="Criar!"/>
        </CardActions>
      </Card>
    </form>
   );
  }
 }
}
Signup = reduxForm({
 form: 'signup',
 validate})(Signup);

export default Signup = connect()(Signup);
