Question

我正在尝试关注Ryan Bates多态模型教程（Rails 3），以在我的照片模型中实现注释。我在尝试为照片创建新评论时遇到了麻烦，因为我在Rails 4中并且我必须处理：评论强参数。

错误：＃＆lt;＃：0x00000107c8a200＆gt;

的未定义方法`user_comments_path'

我有嵌套资源

  #Nesting Resources
  resources :users do
    resources :photos do
      resources :comments
      resources :tags
    end
  end

所以路线应该是/ users / friendly-id / photos / friendly-id / comments，但是它构造得很糟糕，我的表格中有<%= form_for [@user, @commentable, @comment] do |f| %>。

照片控制器

#create
    def show
        @photo = Photo.friendly.find(params[:id])
        @user = @photo.user
        @tag = Tag.new
        @tag.photo_id = @photo.id
        @category = Category.all
        @commentable = @photo
        @comments = @commentable.comments
        @comment = Comment.new
        @zone = Zone.all
        respond_to do |format|
            format.html #show.html.erb
            format.json {render json: @photo}
        end
    end

表格

<%= form_for [@user, @commentable, @comment] do |f| %>
  <% if @comment.errors.any? %>
    <div class="error_messages">
      <h2>Please correct the following errors.</h2>
      <ul>
      <% @comment.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

评论控制器

class CommentsController < ApplicationController
  before_filter :load_commentable

  def index
    @comments = @commentable.comments
  end


  def new
    @comment = @commentable.comments.new
  end

  def create
    @comment = @commentable.comments.new(comment_params)
    if @comment.save
      redirect_to @commentable, notice: "Comment created."
    else
      render :new
    end
  end

private

  def load_commentable
    resource, id = request.path.split('/')[1, 2]
    @commentable = resource.singularize.classify.constantize.find(id)
  end

  def comment_params 
    require(:comment).permit(:photo_id, :user_id, :content)
  end


  ###Error 2: When I put friendly.id instead of only id in `load_commentable` method I get a Forbidden Attribute error.
end

请有人帮忙！谢谢
