Rspe c 'черта не зарегистрирована ошибка при использовании Faker

0 голосов
/ 09 апреля 2020

Я пытаюсь использовать Faker в FactoryBot в моих тестах Rails API.

Проблема, с которой я сталкиваюсь, продолжает вызывать эту ошибку: 

KeyError:
       Trait not registered: "first_name"

Пока что как я могу сказать, я все настроил правильно, по крайней мере, на основе документов Faker'd. Насколько я могу судить, у меня есть две фактические черты, valid_user и invalid_user, которые я установил так ... 

  let(:valid_attributes) { FactoryBot.attributes_for :api_v1_user, :valid_user }
  let(:invalid_attributes) { FactoryBot.attributes_for :api_v1_user, :invalid_user }

, которые связаны с фабрикой :api_v1_user.

Что я пропустил или сделал неправильно?

Полная ошибка: 

8) /api/v1/users PATCH /update with invalid parameters renders a JSON response with errors for the api/v1_user
     Failure/Error: let(:invalid_attributes) { FactoryBot.attributes_for(:api_v1_user, :invalid_user) }

Попробуйте заключить в скобки nil. FactoryBot исключил поддержку атрибутов stati c в версии 5 , поэтому, если вы используете более новую версию, это будет вашей проблемой. Теперь требуются скобки. 

trait :invalid_user do
  first_name { nil }
end
