I need to pass some values from a CMS to a rails view. I should check these values are defined in the CMS. These values are meant to be use in all pages, hence the use of application_controller.rb. As of now Im using a method to check for the existence of a favicon, but this will result in a new validation method for every field (addres, email, phone, etc…).

class ApplicationController < ActionController::Base   before_action :set_constants    def set_favicon     if Fae::Option.instance.try(:favicon).nil?       @favicon = ''     else       @favicon = Fae::Option.instance.favicon.asset.url     end   end   def set_constants    set_favicon    @company            = {       address:       CompanyInfo.instance.address.content,       email:         CompanyInfo.instance.email.content,       phone:         CompanyInfo.instance.phone.content,       facebook_url:  CompanyInfo.instance.facebook_url.content,       instagram_url: CompanyInfo.instance.instagram_url.content,       youtube_url:   CompanyInfo.instance.youtube_url.content   }   end  end
