创建Rails时跳过回调

before-filter callback ruby-on-rails

我想为Rspec测试创建一个活动记录模型。

然而,这个模型有回调,即:before_create和after_create方法(如果我没有错的话,我认为这些方法被称为回调,而不是验证)。

有没有一种方法可以在不触发回调的情况下创建对象?

我以前尝试过的一些解决方案/不适用于我的案例:

更新方法:

update_column和其他更新方法将无法工作,因为我想创建一个对象,并且当对象不存在时,我无法使用更新方法。

工厂女孩和后期建造:

FactoryGirl.define do
  factory :withdrawal_request, class: 'WithdrawalRequest' do
    ...
    after(:build) { WithdrawalRequest.class.skip_callback(:before_create) }
  end
end

失败/错误:在(:build){撤回请求.class.skip_callback(:before_create)}之后

无方法错误: 类的未定义方法“skip_callback”:类

Skip callbacks on Factory Girl and Rspec

跳过回调

WithdrawalRequest.skip_callback(:before_create)

withdrawal_request = WithdrawalRequest.create(withdrawal_params)

WithdrawalRequest.set_callback(:before_create)

失败/错误:撤回请求.skip_callback(:before_create)

How to save a model without running callbacks in Rails

我也试过了

WithdrawalRequest.skip_callbacks = true

这也不管用。

----------编辑-----------

我的工厂功能被编辑为:

after(:build) { WithdrawalRequest.skip_callback(:create, :before, :before_create) }

我的before_create函数如下所示:

class WithdrawalRequest < ActiveRecord::Base
  ...
  before_create do
    ...
  end
end

----------编辑2-----------

我将before_create更改为一个函数,以便可以引用它。这两者中的任何一种都是更好的做法吗?

class WithdrawalRequest < ActiveRecord::Base
  before_create :before_create
  ...
  def before_create
    ...
  end
end

根据参考答案:

FactoryGirl.define do
  factory :withdrawal_request, class: 'WithdrawalRequest' do
    ...
    after(:build) { WithdrawalRequest.skip_callback(:create, :before, :callback_to_be_skipped) }
   #you were getting the errors here initially because you were calling the method on Class, the superclass of WithdrawalRequest

    #OR
    after(:build) {|withdrawal_request| withdrawal_request.class.skip_callback(:create, :before, :callback_to_be_skipped)}

  end
end
