为演示者自定义工厂女孩 linting

Question

如果我让 factory-girl 为演示者执行标准检查，它会失败，并抱怨 save! 没有实现。

是否可以自定义 Presenter 的 linting，使其仅检查是否可以成功构建 Presenter，而不保存它？

主持人

class PostPresenter
  def initialize(post)
    @post = post
  end
end

工厂

FactoryGirl.define do
  factory :post_presenter do
    post
    initialize_with { new(post) }
  end
end

Answer 1

您可以将 skip_create 添加到工厂以完全跳过 to_create 块（通常调用 #save!）。

FactoryGirl.define do
  factory :post_presenter do
    skip_create
    post
    initialize_with { new(post) }
  end
end

或者，您可以实施自定义 to_save 回调：

to_save { post.save! }
