描述

我定义了作者、产品和事件工厂。并且产品可以具有 author_id 值或 null。和事件可以有 product_id 值或空值。我定义了以下关联但没有用。你能告诉我如何定义关联吗？

factory :author do
    first_name FFaker::Name.first_name
    last_name FFaker::Name.last_name
end

factory :product do
    name Faker::Book.title
    factory :product_with_author do
        author
    end
end

factory :event do
name FFaker::Lorem.words
start_time Time.now-3.hours
end_time Time.now+1.hour
    
    factory :upcoming_event do
        is_active true
        product_with_author #I want a product with an author field, "undefined Method Error"
        # I also tried followings but not working, and I have no idea how to define this
        # product :product_with_author (Require Class but Symbol assigned error)
        # product product_with_author  (Implicit Conversion error)
    end

product 

end

Answer 1

我不确定这些关联，但像这样的东西应该有用。它通过为产品定义关联和工厂来为产品创建作者。至于事件，您可以在 before(:create) 或 after(:create) 或 before(:build) 或 after(:build) 中执行此操作。正如我在代码片段中所述，我不知道您的关联，但您可以在该块中将事件传递给产品，反之亦然。

我发现这个 cheatsheet 对我的工厂机器人问题很有帮助

factory :author do
  first_name FFaker::Name.first_name
  last_name FFaker::Name.last_name
end

factory :product do
  name Faker::Book.title
  association :author, factory: :author
end

factory :event do
  name FFaker::Lorem.words
  start_time Time.now-3.hours
  end_time Time.now+1.hour

  factory :upcoming_event do
    after(:create) do |event, evaluator|
      # I'm not sure how event and product are associated
      create(:product)
    end
    
  end
end
