React-Redux-Firebase - populate item with another item

问题

I am using react-redux-firebase. This is how my firebase data looks like once user submit the form:

It pushes information to "contacts" and images to "uploadedFiles"(also used for file Storage path). I really want to have it as one item. Something like:

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

I feel like I should use Populate, but I can not find how to populate one item with another. Will really appreciate any suggestion and useful links.

Here is the code: 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';
import { connect } from 'react-redux';
import { compose, bindActionCreators } from 'redux';
import { firebaseConnect, dataToJS, getFirebase } from 'react-redux-firebase';

// Path within Database for metadata (also used for file Storage path)

      const firebase = getFirebase();
    // Uploads files and push's objects containing metadata to database at dbPath
    // uploadFiles(storagePath, files, dbPath)
    firebase.uploadFiles(filesPath, files, filesPath);
}

  onFileDelete(file, key) {
      const firebase = getFirebase();
    // Deletes file and removes metadata from database
    // deleteFile(storagePath, dbPath)
    firebase.deleteFile(file.fullPath, `${filesPath}/${key}`);
  }

  render() {
    const { uploadedFiles } = this.props
    return (
      <div>
        <Dropzone onDrop={this.onFilesDrop}>
          <div>
            Drag and drop files here
            or click to select
          </div>

              <h3>
                Uploaded file(s):
              </h3>
              {
                map(uploadedFiles, (file, key) => (
                  <div key={file.name + key}>
                    <span>{file.name}</span>
                    <button onClick={() => this.onFileDelete(file, key)}>
                      Delete File
                    </button>
                  </div>
                ))
              }
            </div>
          }

    );
  }
}

Uploader.propTypes = {
    firebase: PropTypes.object.isRequired,
    uploadedFiles: PropTypes.object

export default compose(
  firebaseConnect([
    filesPath
  ]),
  connect(

      uploadedFiles: dataToJS(firebase, filesPath)
    })
  )

      firebase
      .push('contacts', values)

    //   .push('contacts', Object.assign({}, values, { img: 'here I need to pass uploadedFiles' }))

      .then(() => {
        browserHistory.push('/');
    });
}
    render() {

            const uploadArr = uploadedFiles&&Object.values(uploadedFiles);
            const fileToAdd = uploadedFiles&&uploadArr[uploadArr.length-1].downloadURL

            console.log('uploadedFiles!', uploadedFiles&&fileToAdd);
      return (
            <div className="container">
                <AddContactForm onSubmit={this.submit} />
            </div>
      );
    }
}

export default compose(

    { path: 'contacts', queryParams: ['orderByValue'] },
    { path: 'uploadedFiles', queryParams: ['orderByValue'] }

  connect(
    (state) => ({

I would suggest to follow the React Redux "Way" of dealing with Firebase and that to create an Action that deals with Firebase which i am not sure if i am missing it in your code or not. However, when you upload the files in storage you need to set the URI into your Firebase database reference. you should get a URI as a result when you upload a file into the Firebase Storage.

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]
        });
      });

}
