Question

我的评论嵌套在嵌入游戏中的帖子中。我不能为我的生活弄清楚如何添加评论。我得到一个未定义的方法。

 Showing /Users/***/Documents/TestRoutes/app/views/posts/show.html.erb where line #31 raised:

undefined method `post_comments_path' for #<#<Class:0x007fb2159834a0>:0x007fb215980228>

34:     <%= f.text_field :commenter %>

<%= form_for([@post, @post.comments.build]) do |f| %>

   resources :games do
      resources :posts do
        resources :comments
      end
    end

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

class Comment < ActiveRecord::Base
  belongs_to :post
  attr_accessible :body, :commenter
end

class Post < ActiveRecord::Base
  attr_accessible :post, :title, :game_id, :user_id
  belongs_to :user
  belongs_to :game
  has_many :comments

是完整的帖子/评论路线吗？

   resources :games do
      resources :posts do
        resources :comments
      end
   end

如果是这样，你也应该指定游戏，比如

<%= form_for([@game, @post, @post.comments.build]) do |f| %>

重定向行

相同

redirect_to game_post_path(@post)

没有游戏，很可能会引发错误
