React + Redux - フォームコンポーネントで CRUD を処理する最適な方法は何ですか? 質問する

私は見つけたリダックスフォームパッケージ。本当に良い仕事をしてくれます!

だから、戻ってきたとReact-Redux。

まず、フォーム コンポーネントを作成する必要があります (当然のことですが)。

import React from 'react';
import { reduxForm } from 'redux-form';
import validateContact from '../utils/validateContact';

class ContactForm extends React.Component {
  render() {
    const { fields: {name, address, phone}, handleSubmit } = this.props;
    return (
      <form onSubmit={handleSubmit}>
        <label>Name</label>
        <input type="text" {...name}/>
        {name.error && name.touched && <div>{name.error}</div>}

        <label>Address</label>
        <input type="text" {...address} />
        {address.error && address.touched && <div>{address.error}</div>}

        <label>Phone</label>
        <input type="text" {...phone}/>
        {phone.error && phone.touched && <div>{phone.error}</div>}

        <button onClick={handleSubmit}>Submit</button>
      </form>
    );
  }
}

ContactForm = reduxForm({
  form: 'contact',                      // the name of your form and the key to
                                        // where your form's state will be mounted
  fields: ['name', 'address', 'phone'], // a list of all your fields in your form
  validate: validateContact             // a synchronous validation function
})(ContactForm);

export default ContactForm;

import React from 'react';
import { connect } from 'react-redux';
import { initialize } from 'redux-form';
import ContactForm from './ContactForm.react';

class App extends React.Component {

  handleSubmit(data) {
    console.log('Submission received!', data);
    this.props.dispatch(initialize('contact', {})); // clear form
  }

  render() {
    return (
      <div id="app">
        <h1>App</h1>
        <ContactForm onSubmit={this.handleSubmit.bind(this)}/>
      </div>
    );
  }

}

export default connect()(App);

import { combineReducers } from 'redux';
import { appReducer } from './app-reducers';
import { reducer as formReducer } from 'redux-form';

let reducers = combineReducers({
  appReducer, form: formReducer // this is the form reducer
});

export default reducers;

export default function validateContact(data, props) {
  const errors = {};
  if(!data.name) {
    errors.name = 'Required';
  }
  if(data.address && data.address.length > 50) {
    errors.address = 'Must be fewer than 50 characters';
  }
  if(!data.phone) {
    errors.phone = 'Required';
  } else if(!/\d{3}-\d{3}-\d{4}/.test(data.phone)) {
    errors.phone = 'Phone must match the form "999-999-9999"'
  }
  return errors;
}

componentWillMount() {
  this.props.dispatch(initialize('contact', {
    name: 'test'
  }, ['name', 'address', 'phone']));
}

ContactForm = reduxForm({
  form: 'contact',                      // the name of your form and the key to
  fields: ['name', 'address', 'phone'], // a list of all your fields in your form
  validate: validateContact             // a synchronous validation function
}, state => ({
  initialValues: {
    name: state.user.name,
    address: state.user.address,
    phone: state.user.phone,
  },
}))(ContactForm);
