Question

我正在使用react-redux-firebase。这是用户提交表单后我的firebase数据的样子：

它将信息推送到＆＃34;联系人＆＃34;和图像到＆＃34; uploadedFiles＆＃34;（也用于文件存储路径）。我真的想把它作为一个项目。类似的东西：

contacts = {
 kydfsdcfasdfsadf :{
   email: "user@gmail.com",
   firstName: Tom,
   lastName : "Smith",
   uploasedFiles:{
     downloadURL:"dsfsdfsdsdvsdfgdsfgds",
     fullPath:"dfsdfsdf",
     mame:"q34deser4wefwsdf"
   }
 }
}

我觉得我应该使用Populate，但我找不到如何用另一个项填充一个项目。非常感谢任何建议和有用的链接。

这是代码： AddContactForm.js

import { Field, reduxForm } from 'redux-form';
import { browserHistory } from 'react-router';
import Uploader from '../components/Uploader';

const capitalize = value => value.charAt(0).toUpperCase() + value.substring(1);
const lower = value => value && value.toLowerCase();


const AddContactForm = props => {
    const { handleSubmit } = props;
    return (
      <div>
          <h1> Add New Contact</h1>
          <hr />
            <form onSubmit={handleSubmit}>
              <div>
                <label htmlFor="firstName">First Name</label>
                <Field name="firstName" component="input" type="text" normalize={capitalize} />
              </div>
              <div>
                <label htmlFor="lastName">Last Name</label>
                <Field name="lastName" component="input" type="text" normalize={capitalize} />
              </div>
              <div>
                <label htmlFor="email">Email</label>
                <Field name="email" component="input" type="email" normalize={lower} />
              </div>
              <Uploader />
              <button type="submit">Submit</button>
              <button onClick={() => { browserHistory.push('/'); }} >Cancel</button>
            </form>
        </div>
    );
};

AddContactForm = reduxForm({
  // a unique name for the form
  form: 'contact'
})(AddContactForm)

export default AddContactForm;

Uploader.js

import React, { Component } from 'react';
import PropTypes from 'prop-types';

我建议遵循React Redux＆＃34; Way＆＃34;处理Firebase以及创建一个处理Firebase的Action，我不确定我是否在代码中遗漏了它。但是，当您在存储中上传文件时，需要将URI设置为Firebase数据库引用。当您将文件上传到Firebase存储时，您应该获得一个URI。

export function createAccount(data, picture) {
  const { fname, lname, email, password, image } = data;

      storage.child(`/${picture.name}/${new Date().getTime()}`).put(image[0]).then((snapshot) => {
        database.ref('contacts').child(youruserID).set({
         email: "user@gmail.com",
   firstName: Tom,
   lastName : "Smith",
          uploadedfile: snapshot.metadata.downloadURLs[0]
        });
      });

}
