使用 device 和 carrierwave gem 时出现以下错误:

undefined method `user_media_index_path'
.Showing .../user_medias/new.html.erb where line #3 raised:

我在 user_media 模型中添加了 user_id 索引

我已经成功地为单个模型实现了文件上传,但我不知道如何使用单独的模块来实现。

新的.html

form_for @media, :html =>{:multipart =>true} do |f|
  Upload an Image  f.file_field :image
  f.submit 
end

这是使用设备 gem 生成的用户模型:

用户.rb

class User < ActiveRecord::Base

  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  attr_accessible :email, :password, :password_confirmation, :remember_me

  has_many :user_media, dependent: :destroy

end

它是存储用户媒体(如图像等)的模型;我现在仅将其用于图像,但为了将来添加更多类型的媒体,我创建了此 user_media 模型

用户媒体.rb

class UserMedia < ActiveRecord::Base
  attr_accessible :anudio, :image, :video
  belongs_to :user

  mount_uploader :image, MediaUploader
end

当要求创建上传图像的操作时,它会被重定向到这里

用户媒体控制器

class UserMediasController < ApplicationController
  def new
    @media = UserMedia.new
  end

  def create
    @media=current_user.user_media.build(params[:media])

    if @media.save
      render'index'
    else
      render'new'
    end
  end
end

路线详情如下:

路线.rb

Projectx::Application.routes.draw do
  get "dashboard/index"
  resources :dashboard, :UserMedias
  get "home/index"
  devise_for :users

  root :to => 'home#index'

  match 'uploder' =>'UserMedias#new'

添加@peter建议的资源后,rake routes 会输出这一切
