當在STI模型上運行我的規範時獲取Active :: Record :: StatementInvalid

所以，這是我的問題。我有一個名爲AdminNotifications的模型。它屬於AdminUser模型。有一個使用STI從AdminNotification繼承的QuorumAdminNotification模型。它目前是空的。當我跑我的天賦，我得到的所有測試這個錯誤：當在STI模型上運行我的規範時獲取Active :: Record :: StatementInvalid

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

（「仲裁」，「達」，「定額已經達到了」，「管理」，「2012-08-28 十四點50分43' 秒，‘2012-08-28十四點50分43秒’，853808134）

如果我繼承列設置爲一個不存在的列的所有測試都通過了。

有沒有人知道爲什麼會發生這種情況？

下面是相關代碼：

應用程序/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

規格/型號/ 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

規格/夾具/ 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

app/spec/admin_users.yml

admin: 
    email: [email protected] 
    password: password 
    password_confirmation: password

謝謝！
