Reuse query from other model

Is it possible to reuse query methods from different models?

I already have the following model:

class Profile
  belongs_to :user

  def self.search_by_name(search)
    # Some query code...
    # Returns Profile::ActiveRecord_Relation
  end
end

Now I want to implement a similar method: User.search_by_name.

class User
  has_one :profile

  def self.search_by_name(search)
    Profile.search_by_name(search).joins(table_name)
    # Should return User::ActiveRecord_Relation
  end
end

How can I make User.search_by_name to return User::ActiveRecord_Relation? Current solution is returning Profile::ActiveRecord_Relation.

Use Concerns.

app/models/concerns/query.rb

module Query
  extend ActiveSupport::Concern

  module ClassMethods
    def search_by_name(search)
      # Some query code...
    end
  end
end

Then include Query in your Profile and User models.

I can only guess what you try to accomplish but I think your looking for merge

class User
  has_one :profile

  def self.search_by_name(search)
    joins(:profile).merge(Profile.search_by_name(search))
  end
end
