undefined local variable or method `authenticate_admin'

NameError in BlogsController#new

Answer 1

In this case Helpers are accessible in your Views not in Controllers.

Solution is to move your methods from admins_helper.rb to ApplicationController and set them as helper_methods. You will be able to access them in your Controllers and Views.

Example:

class ApplicationController < ActionController::Base

  # Helpers
  helper_method :authenticate_admin

  def authenticate_admin
    deny_admin_access unless admin_signed_in?
  end 

end

Read documentation about helper_method:
