ruby-on-rails - NameError: 未初始化的常量工厂

Question

我正在按照本教程开始使用工厂女孩 rspec 在 Rails 上使用 TDD，但我遇到了这个问题，我无法理解。

这是我的“工厂”.rb (events.rb)

require 'faker'

FactoryGirl.define do
   factory :event do
     name "HIGH"
     genre "house, techno, idb"
     venue_name "Westbourne Studios"
     venue_address "4-6 Chamberlayne Road"
     venue_postcode "NW103JD"
     begin_time "10pm"
     end_time "2am"
     user_id 2
     description "A Super massive party with loads of everything you would want around."
     status true
     venue_id nil
   end
end

这是event_spec.rb：

require 'spec_helper'
require 'factory_girl_rails'

describe Event do

it "has a valid factory" do
  Factory.create(:event).should be_valid
end

  it "is invalid without a name"
  it "is invalid without a genre"
  it "is invalid without a venue_name"
  it "is invalid without a venue_address"
  it "is invalid without a venue_postcode"
  ...

 end

我已经设置了模型，迁移了等等。当我运行“rspec spec/models/event_spec.rb”时，我收到以下错误：

Failures:

1) Event has a valid factory
 Failure/Error: Factory.create(:event).should be_valid
 NameError:
   uninitialized constant Factory
 # ./spec/models/event_spec.rb:7:in `block (2 levels) in <top (required)>'

 Finished in 0.1682 seconds

 Failed examples:

 rspec ./spec/models/event_spec.rb:6 # Event has a valid factory

Answer 1

尝试以这种方式使用它：

FactoryGirl.create(:event).should be_valid

我想，我记得，它只是旧版本的 gem 中的“工厂”。如果您查看最近的 Factory Girl 的“入门”指南，则只有“FactoryGirl”的调用。

Answer 2

如果您创建文件 spec/support/factory_girl.rb 的内容：

RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
end

然后你可以简单地使用：

create(:event)
build(:book)

代替：

FactogyGirl.create(:event)
FactogyGirl.build(:book)

我在使用工厂机器人时遇到了同样的错误，为了补充 Stefan 的回答，我遇到了这个小备忘单。
