Question

如上所述，无法获得“喜欢”按钮工作，发布的更改如下。先感谢您。我修改了路线，模型视图，控制器如下。

充当可投票的迁移

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

路线=

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

指数（公告）

  <%= 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 %>

如果你想制作漂亮的投票系统，你可以使用这些宝石

我在我的应用上使用了thumbs_up并且工作得很好

acts_as_votable按钮不更新
