rails_json_field

A friendly way for users to edit JSON fields in Rails forms.

Add this line to your application's Gemfile:

gem 'rails_json_field'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_json_field

Note: This gem currently requires jQuery to work.

Include the following in your javascript manifest:

//= require rails_json_field

Now you're able to use it in forms:

= form_for @foo do |f|
  = f.json_field :bar

Some future features include:

• Removing the jQuery dependency (if possible)
• Custom class names
• Better default styling
• Nested objects
• Array objects

A special thank you to the john_hancock gem for showing me how to structure this kind of gem.
