acts_as_votable按鈕不更新

問題如上，無法獲得「喜歡」按鈕的工作，發佈更改如下。先謝謝你。我已經修改了路線，模型視圖，控制器如下。acts_as_votable按鈕不更新

充當可投票遷移

class ActsAsVotableMigration < ActiveRecord::Migration 
def self.up 
create_table :votes do |t| 

    t.references :votable, :polymorphic => true 
    t.references :voter, :polymorphic => true 

    t.boolean :vote_flag 
    t.string :vote_scope 

    t.timestamps 
end 

add_index :votes, [:votable_id, :votable_type] 
add_index :votes, [:voter_id, :voter_type] 
add_index :votes, [:voter_id, :voter_type, :vote_scope] 
add_index :votes, [:votable_id, :votable_type, :vote_scope] 
end 

def self.down 
drop_table :votes 
end 
end

路線=

resources :users do 
    resources :posts do 
    member do 
    post :like 
    end 
resources :comments 
end 
end

模型

(User)has_many :posts 
(Post)has_many :comments 
(Post)belongs_to :user 
(Comment)belongs_to :post

控制器（公告）

def like 
@post= Post.find(params[:id]) 
@post.liked_by current_user 
redirect_to :back 
flash[:notice]="Liked!" 
end

指數（職位）

<%= link_to like_user_post_path(post.user,post), :method => :post ,:class =>"" do%> 
     <span class="btn btn-primary editlike"> 
     <%=post.likes.size %> 
<i class="icon-heart "> 
</i></span><%end %>
