How to alias a class method in rails model?

Question

I want to alias a class method on one of my Rails models.

  def self.sub_agent    id = SubAgentStatus.where(name: "active").first.id    where(type: "SubAgent",sub_agent_status_id: id).order(:first_name)       end 

If this was an instance method, I would simply use alias_method, but that doesn't work for class methods. How can I do this without duplicating the method?

Answer 1

You can use:

class Foo      def instance_method           end       alias_method :alias_for_instance_method, :instance_method     def self.class_method    end       class <<self        alias_method :alias_for_class_method, :class_method    end    end   

OR Try:

self.singleton_class.send(:alias_method, :new_name, :original_name) 

Answer 2

I can confirm that:

class <<self   alias_method :alias_for_class_method, :class_method end 

works perfectly even when it is inherited from a base class. Thanks!
