factorygirl創建錯誤

當我用pry在控制檯中調試時，我運行了brief = Factory（：brief，：project => Factory（：project））這個命令。它應該是工作的，但是我得到了這個錯誤。factorygirl創建錯誤

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"

爲什麼會發生此錯誤，我該如何解決？

編輯：我加了我廠的文件

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

請添加您的工廠定義代碼的問題。 – 2013-04-06 01:20:21

我添加了工廠文件。 – 2013-04-06 01:28:26

它看起來像project工廠自動創建brief。因此Factory(:brief,:project => Factory(:project))將嘗試創建與同一個項目相關的兩個摘要。第二個失敗的原因是您在briefs表中的project_id列有一個唯一的約束。

有了您已經定義了你大概可以做你正在試圖撬動做工廠：

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

或者只是：

brief = Factory(:project).brief
