Question

有评论按钮。你应该能够对帖子的节目页面（对该特定帖子的评论索引）或评论的节目页面进行评论

访问此网址时会出现此错误：

... /帖/ 1 /评论/ 1

No route matches {:action=>"upvote", :controller=>"comments", :post_id=>#<Comment id: 1, title: "This is kinda good!", content: "Testing comment", user_id: 1, post_id: 1, created_at: "2014-04-09 21:35:19", updated_at: "2014-04-09 21:35:19">, :id=>nil, :format=>nil} missing required keys: [:id]

当我访问时查看评论列表和按钮：

... /帖/ 1 /

出现类似错误，但

... #<Comment id: nil, title: nil, content: nil, user_id: nil ...

喜欢按钮

<%= link_to "Like", like_post_comment_path(@comment), method: :put, :remote => true %>

路由

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

comments_controller

def upvote
    @post = Post.find(params[:post_id])
    @comment = Comment.find(params[:id])
    @comment.liked_by current_user
    render "update_likes"
  end

当我运行rake路线时

like_post_comment PUT      /posts/:post_id/comments/:id/like(.:format)        comments#upvote                                                                          
dislike_post_comment PUT      /posts/:post_id/comments/:id/dislike(.:format)     comments#downvote

Answer 1

更改

<%= link_to "Like", like_post_comment_path(@comment), method: :put, :remote => true %>

要

<%= link_to "Like", like_post_comment_path(@comment.post_id, @comment), method: :put, :remote => true %>

根据您的路线：

like_post_comment PUT      /posts/:post_id/comments/:id/like(.:format)        comments#upvote

您需要路线中的:post_id和:id。

Answer 2

路线为like_post_comment PUT /posts/:post_id/comments/:id/like(.:format) comments#upvote，这意味着它需要:post_id和:id参数，如下所示：

<%= link_to "Like", like_post_comment_path(:id => @comment.id, :post_id => @post.id), method: :put, :remote => true %>

没有路线匹配{：action =＆gt;＆＃34; upvote＆＃34;，：controller =＆gt;＆＃34;评论＆＃34;，：post_id =＆gt;＃
