跳过创建 Rails 的回调

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（如果我没记错的话，我认为这些方法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？

我之前尝试过的一些解决方案/不适用于我的情况：

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，而当对象不存在时我不能使用更新方法。

Factory Girl and After Build：

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

失败/错误：after(:build) { WithdrawalRequest.class.skip_callback(:before_create) }

无方法错误： 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)

失败/错误：WithdrawalRequest.skip_callback(:before_create)

NoMethodError:undefined method `_before_create_callbacks' for #

How to save a model without running callbacks in Rails

我也试过

WithdrawalRequest.skip_callbacks = true

这也不起作用。

--------- 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。这些中的任何一个都是更好的做法吗？

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

Answer 1

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
