Question

我正在使用铁路3.1.0,我很想知道,能否处理<条码>以下:save和<条码>仅次于_destroy的“平等”。这就是说,在<0>和<代码>之后,我需要使用同样的方法。

此时,我必须单独处理这些反馈,即使这些反馈能够做到同样:

after_save do |record|
  # Make a thing
end

after_destroy do |record|
  # Make the same thing as in the  after_save  callback
end

因此,there 是处理<条码>的一条途径,仅次于_save和<条码> 之后的“destroy“平等”?。

Answer 1

Instead of a block give after_save and after_destroy a method name of your model as a symbol.

class ModelName < AR
  after_save :same_callback_method
  after_destroy :same_callback_method

  def same_callback_method
    # do the same for both callbacks
  end
end

Answer 2

为了在储蓄和销毁之后执行同样的呼吁,可在<条码>之后使用<条码>。

after_commit do |record|
  # Is called after creating, updating, and destroying.
end

Answer 3

class Foo < ActiveRecord::Base
  after_save :my_callback
  after_destroy :my_callback

  private
  def my_callback
    #Do stuff
  end
end
