更改名称后工厂失败

Question

我有一个工厂，当它的符号为:notification_event时工作正常，但是当我将其名称更改为player_notification_event时它会失败并显示错误

  

未初始化的常量PlayerNotificationEvent。

另外，我的其他工厂:property_notification_event也失败了，并出现了错误

  

未初始化的常量PropertyNotificationEvent。

失败的工厂

  factory :player_notification_event do
    notification_eventable_type 'Player'
    association :notification_eventable, factory: :player
    unread_count 1
    last_notif_unread_count 0
    last_email_message_count 0
    last_email_time 5.hours.ago
    last_notif_time 3.hours.ago
  end

  factory :property_notification_event do
    notification_eventable_type 'Property'
    association :notification_eventable, factory: :property
    unread_count 1
    last_notif_unread_count 0
    last_email_message_count 0
    last_email_time 5.hours.ago
    last_notif_time 3.hours.ago
  end

失败的规格

  let(:player_notification_event) { create :player_notification_event }
  let(:property_notification_event) { create :property_notification_event }

  it 'sends email to player' do
    player = player_notification_event.notification_eventable
    allow(UnreadMessagesMailer).to receive_message_chain(:player_email, :deliver_now!)

    described_class.perform
    expect(UnreadMessagesMailer).to have_received(:player_email)
  end

  it 'sends email to property' do
    property = property_notification_event.notification_eventable
    allow(UnreadMessagesMailer).to receive_message_chain(:property_email, :deliver_now!)

    described_class.perform
    expect(UnreadMessagesMailer).to have_received(:property_email)
  end

通过规范

  let(:player_notification_event) { create :notification_event }

  it 'sends email to player' do
    player = player_notification_event.notification_eventable
    allow(UnreadMessagesMailer).to receive_message_chain(:player_email, :deliver_now!)

    described_class.perform
    expect(UnreadMessagesMailer).to have_received(:player_email)
  end

通过工厂

  factory :notification_event do
    notification_eventable_type 'Player'
    association :notification_eventable, factory: :player
    unread_count 1
    last_notif_unread_count 0
    last_email_message_count 0
    last_email_time 5.hours.ago
    last_notif_time 3.hours.ago
  end

您可以在此处使用继承，而不是复制整个工厂。

  

[...]最好为每个类定义一个基本工厂，   创建它所需的属性。然后，创建更具体的   从此基本父级继承的工厂。工厂定义是   仍然是代码，因此请使其保持干燥。   maps.FrozenMap

factory :notification_event do
  unread_count 1
  last_notif_unread_count 0
  last_email_message_count 0
  last_email_time 5.hours.ago
  last_notif_time 3.hours.ago

  factory :player_notification_event do
    notification_eventable_type 'Player'
    association :notification_eventable, factory: :player
  end

  factory :property_notification_event do
    notification_eventable_type 'Property'
    association :notification_eventable, factory: :property
  end
end

由于模型类是从父类factory :notification_event派生的，因此您无需手动指定它。

factory_bot的默认值是查找与factory中的第一个参数同名的类，如果您未显式传递class（请检查{{3} }。试试这个：

factory :player_notification_event, class: NotificationEvent do ...
