Question

我想为Rspec测试创建一个Active Record模型。

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

有没有办法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/对我的案例不起作用：

更新方法：

update_column和其他更新方法不起作用，因为我想创建一个对象，当对象不存在时我不能使用更新方法。

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）之后{WithdrawalRequest.class.skip_callback（：before_create）}

NoMethodError：未定义的方法`skip_callback＆＃39;对于类：类

跳过回拨

WithdrawalRequest.skip_callback(:before_create)

withdrawal_request = WithdrawalRequest.create(withdrawal_params)

WithdrawalRequest.set_callback(:before_create)

失败/错误：WithdrawalRequest.skip_callback（：before_create）

NoMethodError：未定义的方法`_before_create_callbacks＆＃39;对于＃

我也试过

WithdrawalRequest.skip_callbacks = true

哪个也行不通。

----------编辑-----------

我的工厂功能编辑为：

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，以便我可以引用它。这些都是更好的做法吗？

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
