Question

I want a method within

class User < ActiveRecord::Base
  def global_user_id
    User.find_by_username("Global_User").id
  end
end

which returns the current global user ID. I want it to be run using User.global_user_id rather than something like User.new.global_user_id

How would I do this?

I’m needing the user ID in other models and right now its stuck in class resources which I dont think is the best spot.

Answer 1

The key is the self. in the name, it means that this function is a static one tied to the class and not to an instance of it.

class User < ActiveRecord::Base
  def self.global_user_id
    find_by_username("Global_User").id
  end
end
