我收到以下錯誤轉儲格式錯誤：的Rails 3.2.10符號（0×46）
模型：
dump format error for symbol(0x46)
已實施以下方法應用後
def common_friends(user)
(self.following & user.following).count
end
def top_5_by_shared_friends
following.sort_by{|user| common_friends(user)}.reverse.first(5)
end
在我看來：
<%= render :partial => 'users/user_profile_summary', :collection => @shared_friends, :as => :user %>
在我的控制器：
@shared_friends = @current_user.top_5_by_shared_friends
現在我只當我渲染部分在我看來，這個錯誤信息。即如果我刪除了「呈現部分」行，應用程序就會正常加載，除非它不顯示我想要的內容。
看到應用程序堆棧跟蹤如下：

我已經確定了錯誤的原因：
在我的部分的一個部分，我呼籲：
<li class = "follower_count"><%= pluralize(user.followers.count, "follower") %></li>
只需放置user.followers.count就會產生錯誤。這顯然與我的模型方法相沖突，但我不明白爲什麼。
這裏是關係模型 - 追隨者依賴於：reverse_relationship，我認爲有錯誤發生，但我不知道爲什麼會發生在這裏只而不是節目裏我也呼籲追隨者的其他部分：
has_many :relationships, :foreign_key => "follower_id", :dependent => :destroy
has_many :reverse_relationships, :foreign_key => "followed_id", :dependent => :destroy, :class_name => "Relationship"
has_many :following, :through => :relationships, :source => :followed
has_many :followers, :through => :reverse_relationships, :source => :follower
