React Rails form data

React component that serializes arbitrary JS objects into hidden fields for Ruby on Rails

Background

Created by UsabilityHub as a helper to serializes JS objects used by React into hidden form fields. The fields are named so that they are interpreted correctly by Rails. Can handle complex nested objects.

Install

npm install react-rails-form-data --save

Usage

import React from 'react'
import RailsFormData from 'react-rails-form-data'

export default class FormDataExample({ uri }) {
  const data = {
    name: 'Jane Smith',
    dateOfBirth: '1991-01-01',
    favoriteColors: ['red', 'magenta']
  }

  return (
    <form action={uri}>
      <RailsFormData path='person' data={data} />
      <button type='submit'>
        Post {data.name}'s data to {uri}.
      </button>
    </form>
  )
}

<form action='http://example.com/people'>
  <div style='display: none;'>
    <input type='hidden' name='person[name]' value='Jane Smith' />
    <input type='hidden' name='person[dateOfBirth]' value='1992-01-01' />
    <input type='hidden' name='person[favoriteColors][]' value='red' />
    <input type='hidden' name='person[favoriteColors][]' value='magenta' />
