FactoryGirl Rspec 和 SQLite3::ConstraintException

Question

我正在尝试创建一些关联的工厂，但事件不起作用：

factories.rb

  factory :user, class: User do
    first_name 'John'
    last_name 'Doe'
    email { "#{first_name}.#{last_name}@example.com".downcase } 
    username 'johndoe'
    password 'johndoe'
    password_confirmation 'johndoe'

    association :account_id, factory: :account 
  end

  factory :account, class: Account do
    #id is the only field
  end

  factory :event, class: Event do
    name 'Go to the Dentist'
    start_date "#{Time.now.next_month}"  
    end_date "#{Time.now+1.hour.next_month}" 
    copyright "#{Time.now.year}" 

    association :account_id, factory: :account  
  end 

controller_spec.rb

before(:each) do
  @request.env["devise.mapping"] = Devise.mappings[:user]
  @user = FactoryGirl.create(:user_profile, :username => 'johndoe' )
  sign_in @user
  @acct = FactoryGirl.create(:account, :id => @user.account_id)
  @event = FactoryGirl.create(:event, :account_id => @acct.id)
end

但这条事件线是一切都出错的地方。即使我使用@user.account_id 为事件设置：account_id，它也会失败并出现以下错误：

Failure/Error: @event = FactoryGirl.create(:event, :account_id => @acct.id)
     ActiveRecord::StatementInvalid:
       SQLite3::ConstraintException: constraint failed: INSERT INTO "event" ("account_id", "copyright", "created_at", "deleted", "end_date", "info", "name", "start_date", "type", "updated_at") VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
     # ./spec/controllers/controller_spec.rb:13:in `block (3 levels) in <top (required)>'

非常感谢您对此提供的任何建议！

我认为您收到约束异常的原因是您的表中已经有一些数据与您尝试添加的信息相冲突。

您可能想删除所有数据，然后尝试 rspec 测试用例。
