Ruby on Rails before_render filter

Adds missing before_render filter

Bypasses Rails filtering mechanism to ensure simplicity and compatibility with Rails 3, 4 and 5.

Install

Gemfile

gem 'rails_before_render'

Example

We will add filter that will dump @product to json

• if we are in development
• params[:debug] is present
• @product is defined

class AppllicationController

  before_render_filter do
    if Rails.env.development? && params[:debug]
      render json: @product.to_h if @product
    end
  end

end
