跳过创建时的回调 Rails

Question

我想为 Rspec 测试创建一个 Active Record 模型。

不过，这个模型有回调，即：before_create和after_create方法（我觉得这些方法叫回调不验证如果我没记错的话）。

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/对我的情况不起作用：

更新方法：

update_column等更新方法将不起作用，因为我想创建一个对象，当对象不存在时我无法使用更新方法。

工厂女工和改造后：

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

Failure/Error: after(:build) { WithdrawalRequest.class.skip_callback(:before_create) }

没有方法错误： Class:Class

的未定义方法 `skip_callback'

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)

Failure/Error: WithdrawalRequest.skip_callback(:before_create)

NoMethodError：#

的未定义方法“_before_create_callbacks”

How to save a model without running callbacks in Rails

我也试过了

WithdrawalRequest.skip_callbacks = true

哪个也不行。

------------编辑------------

我的工厂函数被编辑为：

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
