tag_count 方法为我的 GroupsController 中的所有记录提供相同的值:
@group_blog_tags=@group.blog.blog_posts.tag_counts
在哪里
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
但无论我选择哪个组,它总是获取标签表中的第一条记录。
我究竟做错了什么?

@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!
