错误acts_as_taggable_on_steroids - tags_counts方法

Question

的TAG_COUNT方法给出了所有的记录 在我GroupsController我有相同的价值：

@group_blog_tags=@group.blog.blog_posts.tag_counts 

其中

 class Group < ActiveRecord::Base 
     has_one :blog, :as => :owner, :dependent => :destroy 


     class Blog < ActiveRecord::Base 
      has_many :blog_posts, :order => "blog_posts.created_at desc", :dependent => 
      :destroy 

但它始终是取第一个记录在标签表中，不管我选择哪个组。

我在做什么错？

@group=Group.find(45) => #<Group id: 45, name: "Royal P&O Princess", description:

     @group.blog.blog_posts.tag_counts   => [#<Tag id: 1, name: "acticity 
    stream message">]  


     Trying another group: 
     Group.find(40).blog.blog_posts.tag_counts => [#<Tag id: 1, name: "acticity 
     stream message">] 

它总是获取与结果相同的记录！

Answer 1

我认为一个组“belongs_to”是一个博客，而不是“has_one”。

编辑

您必须指定组和博客之间的关系。它可以是这样的情况：

• A组HAS_ONE博客，博客belongs_to的一组
• A组的has_many博客，belongs_to的一组
• A组belongs_to的博客，博客HAS_ONE组
一个博客
• A组belongs_to的博客，博客的has_many组
• A组has_one_and_belongs_to_many博客，博客has_one_and_belongs_to_many组

A x belongs_to y意味着您的x表中有一个y_id。

A x has_one y或x has_many y指定每个x的y的数量。

一个x has_and_belongs_to_many y意味着x有许多y和y的has_many x。
