Set filter before_action for ActiveAdmin controller

Question

I want to add before_action filter to ActiveAdmin controller.

Could I do something like this:

before_action :set_product, only: [:show, :edit, :update, :destroy]

private

def set_product
  @product = Product.find_by_name(params[:name])
end

Solution 1

You can access the controller from within the controller do ... end DSL:

ActiveAdmin.register User do

  before_action :set_product, only: [:show, :edit, :update, :destroy]

  controller do
    def set_product
      @product = Product.find_by_name(params[:name])
    end
  end

end

Solution 2

You can store it in the config: config/initializers/active_admin.rb

ActiveAdmin.setup do |config|
  def do_something_awesome
  end

  config.before_action :do_something_awesome      
end

For newer versions of activeadmin, before_filter should be within the controller block.

@OscarBarrett No, it works for me for the latest version of Active Admin (at the moment of writing this).
