我被困住了。我需要你的帮助，拜托。即使我使用了经过验证的路径rake routes

user_queue_videos GET    /users/:user_id/queue_videos(.:format)          queue_videos#index

我收到以下错误：

ActionController::RoutingError at /videos
No route matches {:controller=>"queue_videos"}

视图中的链接

%li= link_to "My Queue", user_queue_videos_path

路线.rb

  resources :users, only: [:new, :create] do
    resources :queue_videos
  end

queue_videos_controller

  class QueueVideosController < ApplicationController
    before_filter :require_user

    def index
      @videos = current_user.my_queued_videos
    end

  end

我尝试使用member routes但它不起作用，所以我拿走了但它仍然没有呈现索引模板......

第二次尝试：当我放

  class QueueVideosController < ApplicationController
    before_filter :require_user

    def index
      @user.id = current_user.id #current_user is defined in ApplicationController
      @videos = current_user.my_queued_videos
    end

  end

在视野中

  %li= link_to "My Queue", user_queue_videos_path(@user.id)

它给了我以下错误：

RuntimeError at /videos
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id

第三次尝试：然后我尝试了以下操作： 在视图中

  %li= link_to "My Queue", user_queue_videos_path(current_user.id)

它给了我以下错误：

NoMethodError at /users/1/queue_videos

undefined method `id=' for nil:NilClass

注意：在 ApplicationController

  class ApplicationController < ActionController::Base
    protect_from_forgery

    helper_method :logged_in?, :current_user

    def current_user
      @current_user ||= User.find(session[:user_id]) if session[:user_id]
    end

    def logged_in?
      !!current_user
    end

    def require_user
      unless logged_in?
        flash[:error] = "You don't have permission to do this"
        redirect_to root_path
      end
    end
  end

根据您的rake routes输出，routes.rb您需要传递user_id因为是用户的成员。例如：

%li= link_to "My Queue", user_queue_videos_path(current_user.id)

希望这可以帮助！
