我有模型關聯如下:軌與各協會ActiveRecord的驗證

 class Group < ActiveRecord::Base 
     has_many :group_links, :dependent => :destroy 
    end 

     class GroupLink < ActiveRecord::Base 
     belongs_to :group 
     validates_presence_of :group_id 
     validates_presence_of :url, :message => "We need a url to create a link" 
     validates_uniqueness_of :url, :message => "A link with this url already exists" 
     validates_presence_of :text, :message => "We need a text to create a link" 
     validates_uniqueness_of :text, :message => "A link with this text already exists" 
     end 

我希望它像每個組的組鏈接應該是唯一的工作。然而,它的工作方式是,即使某些其他組擁有簡化組鏈接,它也會拋出驗證錯誤。

我在做什麼錯?

在此先感謝,

我用:範圍=>:GROUP_ID我唯一的驗證來得到這個工作
