Controller extension?

Question

Ruby on Rails

Hello. And do not tell me how to do it right if I want to add methods to the controller, for example, sending data
1) include the Mailer module
2) create a separate Mailer class based on ApplicationController and already create subclasses
3) create a separate Mailer class, and create instances of Mailer in the controller. new?
Or is there a better solution, thanks?

Maybe this will help you rusrails.ru/action-mailer-basics ?
In general, I think that in the controller there should be only a call to the "container" (where some calculations take place, getting data from the database, for example, trailblazer, dry solve this problem) and rendering the received, i.e. Literally 3-4 lines of code.
Here is an example from triblazer:

class Song::Create < Trailblazer::Operation
  step    Model( Song, :new )
  step    :assign_current_user!
  step    Contract::Build( constant: MyContract )
  step    Contract::Validate()
  failure :log_error!
  step    Contract::Persist()

  def log_error!(options)
    # ..
  end

  def assign_current_user!(options)
    options["model"].created_by =
      options["current_user"]
  end
end
####
result = Song::Create.({ title: "The Feeling Is Alright" }, "current_user": current_user)
result.success? #=> true
