FactoryGirl不会输出与build_attributes的关联

Question

我可能在这里做了一些非常愚蠢的事情，但我无法通过测试，因为FactoryGirl.attributes_for未输出关系字段。

这里是我的project厂：

FactoryGirl.define do 
    factory :project do 
    status 'active' 
    loan_amount 5000 
    start_date Time.now 
    end_date Time.now + 2.week.to_i 
    description "Sample Project" 
    user 
    end 
end 

这里是我试图让这个测试通过测试：

let(:user) { FactoryGirl.create(:user) } 
let(:project_attributes) { FactoryGirl.attributes_for(:project, user: user) } 

it 'assigns a newly created project as @project' do 
    post :create, { project: project_attributes } 
    expect(assigns(:project)).to be_a(Project) 
    expect(assigns(:project)).to be_persisted 
end 

这是project_attributes输出：

{:status=>"active", :loan_amount=>5000, :start_date=>2015-12-21 12:07:32 -0800, :end_date=>2016-01-04 12:07:32 -0800, :description=>"Sample Project"} 

这给了我一个错误：

@messages={:user=>["can't be blank"]}> 

任何想法？为什么FactoryGirl在使用attributes_for时不输出用户？

Answer 1

它看起来像你的:project工厂定义是有点关闭。如果项目belongs_to用户，工厂需要说association :user，如

factory :project do 
    status 'active' 
    loan_amount 5000 
    start_date Time.now 
    end_date Time.now + 2.week.to_i 
    description "Sample Project" 
    association :user 
end
