  insert_before_action :new_action2, after: :action1
end

SamplesController.__callbacks[:process_action].map(&:filter) #=> [:new_action1, :action1, :new_action2, :action2]

SamplesController.delete_before_action :new_action1

SamplesController.__callbacks[:process_action].map(&:filter) #=> [:action1, :new_action2, :action2]

Model

Example:

class Sample < ActiveRecord::Base
  before_save :action1
  before_save :action2

  insert_before_save :new_action1, before: :action1
  insert_before_save :new_action2, after: :action1
end

Sample.__callbacks[:save].map(&:filter) #=> [:new_action1, :action1, :new_action2, :action2]

Sample.delete_before_save :new_action1

Sample.__callbacks[:save].map(&:filter) #=> [:action1, :new_action2, :action2]

Supported callbacks are validation, save, create, update and destroy.

Example:

class SampleJob < ActiveJob::Base
  before_perform :action1
  before_perform :action2

  insert_before_perform :new_action1, before: :action1
  insert_before_perform :new_action2, after: :action1
end

SampleJob.__callbacks[:perform].map(&:filter) #=> [:new_action1, :action1, :new_action2, :action2]

SampleJob.delete_before_perform :new_action1

SampleJob.__callbacks[:perform].map(&:filter) #=> [:action1, :new_action2, :action2]

Supported callbacks are enqueue and perform.

Example:

class SampleMailer < ActionMailer::Base
  before_deliver :action1
  before_deliver :action2

  insert_before_deliver :new_action1, before: :action1

end

SampleMailer.__callbacks[:deliver].map(&:filter) #=> [:new_action1, :action1, :new_action2, :action2]

SampleMailer.delete_before_deliver :new_action1
