Grouping actions

You can use the stage method to group multiple methods into one execution group.

INFO

Usage of the position option for make will sort only in stage.

stage do
  make :create_user!
  make :create_blog_for_user!
  make :create_post_for_user_blog!
end

Option only_if

Before calling methods inside stage, the condition described in only_if will be checked.

stage do
  only_if ->(context:) { Settings.features.preview.enabled }
  
  make :create_user!
  make :create_blog_for_user!
  make :create_post_for_user_blog!
end

Option only_unless

stage do
  only_unless ->(context:) { Settings.features.preview.disabled }
  
  make :create_user!
  make :create_blog_for_user!
  make :create_post_for_user_blog!
end

The opposite of the only_if option.

Option wrap_in

Group of methods in stage can be wrapped in something. For example, it could be ActiveRecord::Base.transaction from Rails.

stage do
  wrap_in ->(methods:, context:) { ActiveRecord::Base.transaction { methods.call } }
  
  make :create_user!
  make :create_blog_for_user!
  make :create_post_for_user_blog!
end

Option rollback

If an exception occurs in one of the methods in the group or in wrap_in, this can be handled using the rollback method.

stage do
  wrap_in ->(methods:, context:) { ActiveRecord::Base.transaction { methods.call } }
  rollback :clear_data_and_fail!
  
  make :create_user!
  make :create_blog_for_user!
  make :create_post_for_user_blog!
end

# ...

def clear_data_and_fail!(e)
  # ...

  fail!(message: "Failed to create data: #{e.message}")
end
