factorygirl创建错误

当我用pry在控制台中调试时，我运行了brief = Factory（：brief，：project => Factory（：project））这个命令。它应该是工作的，但是我得到了这个错误。factorygirl创建错误

ActiveRecord::RecordNotUnique: PG::Error: ERROR: duplicate key value violates unique constraint "index_briefs_on_project_id" 
    DETAIL: Key (project_id)=(15389) already exists. 
    : INSERT INTO "briefs" ("project_id", "duration", "brand_name", "brand_info", 
"customer_info", "competitor_info", "desired_impression", "competencies", "preferences", 
"examples", "notes", "created_at", "updated_at", "channel_id") VALUES (15389, 14, NULL, 
'brand info', NULL, NULL, NULL, NULL, NULL, NULL, NULL, 
'2013-04-06 01:07:04.717364', '2013-04-06 01:07:04.717364', NULL) RETURNING "id"

为什么会发生此错误，我该如何解决？

编辑：我加了我厂的文件

brief_factory.rb

Factory.define :brief, :class => Brief do |b| 
    b.brand_info 'brand info' 
    b.duration 14 
end

project_factory.rb

Factory.define :project, :class => Project do |p| 
    p.association :owner, :factory => :customer 

    p.title 'project title' 
    p.description 'project description' 
    p.stage :brief_completed 
    p.contest_type :standard 

    p.brief Factory.build(:brief) 
    p.association :project_type, :factory => :project_type 
end

请添加您的工厂定义代码的问题。 – 2013-04-06 01:20:21

我添加了工厂文件。 – 2013-04-06 01:28:26

它看起来像project工厂自动创建brief。因此Factory(:brief,:project => Factory(:project))将尝试创建与同一个项目相关的两个摘要。第二个失败的原因是您在briefs表中的project_id列有一个唯一的约束。

有了您已经定义了你大概可以做你正在试图撬动做工厂：

project = Factory(:project) 
brief = project.brief

或者只是：

brief = Factory(:project).brief
