Add this line to your application's Gemfile:

gem 'frondit', github: 'jpmobiletanaka/frondit'

And then execute:

$ bundle

Add to your ApplicationController

include Frondit

And then call from any controller you want:

frondit `policy`, [ only: `rules list, on: `actions list`, record: `record` ]

policy is a class_name or underscored class_name: Admin::PostPolicy or admin/post_policy

For example:

before_action :set_post
...
frondit :post_policy, only: %i[show? edit? update?], on: %i[index show], record: :@post
frondit AuthorPolicy, on: :index, record: :@post
frondit :book_policy, record: :@post
frondit Admin::PostPolicy
...
def set_post
  @post = Post.find(params[:post_id])
end

record should be string/symbol with variable name which available before action.

You should declare before_action method with assigning variable before call frondit.

If your variable is @post, you should pass :@post or "@post" to frondit

After that your policies will be accessed from JS

policies() // => Array

Particular policy:

policy('PostPolicy') // => Object
policy('PostPolicy').index // => true
policy('PostPolicy').edit // => false

Be careful, always use Pundit policies and his authorize method in your controllers while using Frondit. Frondit isn't secure because of JS constrains.

Frondit supports Ruby 2.2 , Rails. 4.1
