Question

所以，这是我的问题。我有一个名为AdminNotifications的模型。它属于AdminUser模型。有一个QuorumAdminNotification模型，它继承自使用STI的AdminNotification。它目前是空的。当我运行我的规范时，我在所有测试中都会出现此错误：

Failure/Error: Unable to find matching line from backtrace
     ActiveRecord::StatementInvalid:
       PG::Error: ERROR:  column "admin_user" of relation "admin_notifications" does not exist
       LINE 1: ...admin_notifications" ("type", "event", "message", "admin_use...
                                                                    ^
       : INSERT INTO "admin_notifications" ("type", "event", "message", "admin_user", "created_at", "updated_at", "id") VALUES

（'Quorum'，'达到'，'已达到Quorum'，'admin'，'2012-08-28 14：50：43'，'2012-08-28 14：50：43'，853808134）

如果我将继承列设置为不存在的列，则所有测试都会通过。

有谁知道为什么会这样？

以下是相关代码：

应用程序/模型/ admin_notification.rb

class AdminNotification < ActiveRecord::Base
  belongs_to :admin_user

  attr_accessible :message, :model, :record_id, :type

  scope :addressed, where('admin_user_id IS NOT NULL')
  scope :unaddressed, where('admin_user_id IS NULL')

  def addressed?
    !admin_user.nil?
  end
end

规格/模型/ admin_notification_spec.rb

describe AdminNotification do
  fixtures :admin_notifications

  describe "#addressed?" do
    it "should return false if admin_user is not set" do
      AdminNotification.new.should_not be_addressed
    end

    it "should return true when admin_user is set" do
      notification = AdminNotification.new
      notification.stub(:admin_user).and_return(mock(AdminUser, nil?: false))
      notification.should be_addressed
    end
  end

  describe "addressed scope" do
    it "returns all addressed notifications" do
      AdminNotification.addressed.should == admin_notifications(:addressed1, :addressed2)
    end
  end

  describe "unaddressed scope" do
    it "returns all unaddressed notifications" do
      AdminNotification.unaddressed.should == admin_notifications(:unaddressed1, :unaddressed2)
    end
  end
end

规格/装置/ admin_notification.yml

unaddressed1:
  type: Quorum
  event: reached 
  message: "Quorum has been reached"

unaddressed2:
  type: Quorum
  event: test 
  message: "Test message"

addressed1:
  type: Quorum
  event: reached 
  message: "Quorum has been reached"
  admin_user: admin

addressed2:
  type: Quorum
  event: reached 
  message: "Quorum has been reached"
  admin_user: admin

应用程序/规格/ admin_users.yml

admin:
  email: admin@example.com
  password: password
  password_confirmation: password

谢谢！

修正了它。

问题在于灯具中的类型字段

应该是

QuorumAdminNotification

不

仲裁

在STI模型上运行我的规范时获取Active :: Record :: StatementInvalid
