添加acts_as_votable投票到帖子和評論，路由問題？

Question

我想在我的rails應用程序的帖子和評論中使用acts_as_votable投票系統。我目前產生了我comments#upvote和comments#downvote一些明顯不當的路線，在這裏，他們都低於：

upvote_post PUT /posts/:id/upvote(.:format)     comments#upvote 

downvote_post PUT /posts/:id/downvote(.:format)    comments#downvote 

但他們路由都需要像/posts/comment/:id/downvote。這裏是我目前如何做我的路線

resources :posts do 
    member do 
    put "like", to: "posts#upvote" 
    put "dislike", to: "posts#downvote" 
    end 
    resources :comments 
    member do 
    put "upvote", to: "comments#upvote" 
    put "downvote", to: "comments#downvote" 
    end 
    end 

此外，我需要兩張選票表，因爲我希望這兩個評論和帖子可投票？ 這裏是我的我的意見控制器如果需要的話：

class CommentsController < ApplicationController 
    before_filter :authenticate_user!, :except => [:index, :show] 
    def index 
    @post = Post.find(params[:post_id]) 
    @user = User.find(params[:user_id]) 
    @comments = @post.comments.order('created_at desc') 
    end 

    def new 
    @post = Post.find(params[:post_id]) 
    @comment = @post.comments.new(params[:id]) 

    end 


    def create 
     @post = Post.find(params[:post_id]) 
     @comment = @post.comments.create(comment_params) 

     @comment.post_id = @post.id 
     @comment.user_id = current_user.id 

    if @comment.save 
     redirect_to post_comments_path(@post) 
    else 

     redirect_to new_post_comment_path(post) 
    end 
    end 

    def destroy 
    end 

    def upvote 
    @post = Post.find(params[:post_id]) 
    @comment = @post.comments.find(params[:id]) 
    @comment.upvote_by current_user 
    redirect_to post_comments_path(@post) 
    end 

    def downvote 
    @post = Post.find(params[:post_id]) 
    @comment = @post.comments.find(params[:id]) 
    @comment.downvote_by current_user 
    redirect_to post_comments_path(@post) 
    end 


private 

    def comment_params 
    params.require(:comment).permit(:body, :post_id, :user_id) 
    end 
end 

感謝您的幫助

正如你可能不想窩你的路由如此之深的規則。而評論投票並不需要知道帖子的id，只是評論。你也可能會發現，而不是有一個單獨的方法爲上下具有投票控制器投票轉到VotesController，只是處理它有

所以，我會做這樣的事情：

resources :posts do 
    resources :comments, only: [:new, :create, :destroy] 
    resources :votes, only: [:create, :update, :destroy] 
end 

resources :comment do 
    resources :votes, only: [:create, :update, :destroy] 
end 

，如果你想擁有的投票是在兩個多態關係，在這種情況下你ApplicationsController你要等的方法那是：

def find_model 
    params.each do |name, value| 
     if name =~ /(.+)_id\z/ 
     return $1.classify.constantize.find(value) 
     end 
    end 
    nil 
    end 

# VotesController 

def create 
    model = find_model 
    if model 
    # do stuff 
    end 
end 

如果你有單獨表決表，你可以跳過這最後一部分。

也有類似的問題，通過改變

put "like", to: "posts#upvote" 
put "dislike", to: "posts#downvote 

固定它

get "like", to: "posts#upvote" 
get "dislike", to: "posts#downvote" 

posts_controller

def upvote 
    @post.upvote_by current_user 
    redirect_to :back 
end 

def downvote 
    @post.downvote_by current_user 
    redirect_to :back 
end 

展後頁

<%= link_to "like", like_post_path(@post), method: :get %> 
<%= link_to "dislike", dislike_post_path(@post), method: :get %> 

希望這有助於
