未定義的方法`index_path」使用關係

Question

我開始使用設備和carrierwave寶石以下錯誤：

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

我在user_media車型增加了指數上的user_id

我已經成功地實現文件上傳爲單模型，但我不知道如何與一個單獨的模塊做到這一點。

new.html

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

這是使用設備寶石產生的用戶模型：

user.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 

其模型來存儲用戶媒體像圖像等我;現在使用此僅適用於圖像 但爲futu再添加更多類型的媒體我創造了這個user_media模型

user_media.rb

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

    mount_uploader :image, MediaUploader 
end 

這是其重定向當被問及對於將圖像上載

創建行動

user_medias_controller

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 

個

路由細節：

的routes.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' 

耙路輸出這一切都將通過@peter

錯誤點建議資源丟失後在你的路線文件中路由。添加到您的路線

resources :user_medias
