Rails 3 - 工厂女孩宝石 - belongs_to和has_one关系

Question

我有用户和教师模型.教师belongs_to用户和用户has_one教师.我也有工厂女孩文件中的代码:

Factory.define :user do |user|
  user.user_login "Another User"
  user.user_role "admin"
  user.password "foobar"
end

Factory.sequence :user_login do |n|
  "person-#{n}"
end

Factory.define :teacher do |teacher|
  teacher.teacher_last_name   'Last'
  teacher.teacher_first_name  'First'
  teacher.teacher_middle_name 'Middle'
  teacher.teacher_birthday    '01.11.1980'
  teacher.teacher_category    'First category'
  teacher.teacher_sex         'm'
end

当我尝试在我的规范中创建一名教师时:

@teacher = Factory(:teacher)

然后我收到错误:

Failure/Error: @teacher = Factory(:teacher)
     ActiveRecord::RecordInvalid:
       Validation failed: User can't be blank

据我所知,这是因为我不告诉Factory我的老师belongs_to用户.我该如何解决这个问题？

Answer 1

您应该定义关联:

Factory.define :teacher do |teacher|
  ...
  teacher.user
end

Factory Girl有精彩的教程,我建议你看一下.

PS为什么要将这些奇怪的前缀(user_,teacher_)添加到模型属性中？它看起来很丑陋,所以你肯定做错了什么.
