Ruby on Rails FactoryGirl不生成具有多個關聯的工廠

Question

我的student_status標識存儲不同的關聯。例如，student_status_id爲1意味着學生處於活動狀態，所以我生成這些不同的id是不可或缺的。我試過創建一個沒有student_status_id 1的FactoryGirl用戶，代碼打破了告訴我沒有status_id。此外，如何使用FactoryGirl來生成說7的status_id？

FactoryGirl.define do 
    factory :user do 
    first_name 'example' 
    last_name 'user' 
    email 'example@user.com' 
    username 'example' 
    password 'abcdef' 
    password_confirmation 'abcdef' 
    birthdate DateTime.new(1990,9,1,17) 
    student 
    end 
end 

FactoryGirl.define do 
    factory :student_status do 
    name 'Active' 
    student 
    end 
end  

FactoryGirl.define do 
    factory :student do 
    points 20 
    session_minutes 120 
    weekly_session_minutes 120 
    can_schedule_self false 
    next_monthly_cycle DateTime.new(2015,9,1,17) 
    student_status_id 1 
    end 
end 

這裏的表在我的架構中定義

create_table "student_statuses", force: :cascade do |t| 
    t.string "name" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    end 

    create_table "students", force: :cascade do |t| 
    t.integer "user_id" 
    t.integer "lesson_id" 
    t.integer "points" 
    t.integer "student_status_id" 
    t.date  "next_monthly_cycle" 
    t.integer "session_minutes",  default: 0, null: false 
    t.date  "next_session_minutes" 
    t.date  "next_session_schedule" 
    t.integer "weekly_session_minutes", default: 0, null: false 
    t.boolean "can_schedule_self",  default: true, null: false 
    end 

Answer 1

所以，你有一個1：1的關聯，例如student_id在student_status表中，而student_status_id在students表中同時出現？

試試這個：

FactoryGirl.define do 
    factory(:student) do 
    points 20 
    session_minutes 120 
    weekly_session_minutes 120 
    can_schedule_self false 
    next_monthly_cycle DateTime.new(2015,9,1,17) 
    association(:status, factory: :student_status) 
    end 
end 

FactoryGirl.define do 
    factory(:student_status) do 
    name { ['Active', 'Inactive', 'SomeOther'].sample } 
    end 
end 

此外，請確保您在Student類有這樣的：

belongs_to :student_status 

之後，從鐵軌控制檯試試這個：

FactoryGirl.load 
student = FactoryGirl.create(:student) 
puts student.status # => should return actual random status
