Question

我有一个没有问题的网站。这是路线文件：

Testpager::Application.routes.draw do
  devise_for :users
  resources :news,      only: [:index, :show]
  resources :documents, only: [:index, :show]

  namespace :admin do
    resources :documents, only: [:index, :show, :destroy, :edit, :update, :new, :create]
    resources :news,      only: [:index, :show, :destroy, :edit, :update, :new, :create]
    get "admin" => 'documents#index'
  end

  get "contacts/index"
  get "services/index"
  get "index/index"
  get "admin/index"

  root 'index#index'
end

我想添加一个注册系统。要做到这一点，我正在使用Devise。

我的行动是：

我安装了Devise gem。
跑rails g devise:install

将此添加到application.html.erb：

<p class="notice"><%= notice %></p>
<p class="alert"><%= alert %></p>

跑rails g devisw User
跑rake db:migrate
跑rails server
我打开了网址http://localhost:3000/users/sign_up

我收到以下错误消息：

ActionController::UrlGenerationError in Devise::Registrations#new
Showing /home/kalinin/rails/testpager/app/views/shared/_nav_main.html.erb where line #6 raised:
No route matches {:action=>"index", :controller=>"devise/index"}
Extracted source (around line #6):      
    <ul>
        <li>
            <%= link_to 'index', controller: "index", action: "index" %>
        </li>
Trace of template inclusion: app/views/layouts/application.html.erb

这是控制器：

class IndexController < ApplicationController
  def index
  end
end

IndexController的视图存在。

查看此链接关于向设计注册添加自定义字段：http://jacopretorius.net/2014/03/adding-custom-fields-to-your-devise-user-model-in-rails-4.html。您需要做的是设置一个继承自Devise :: RegistrationsController的注册控制器。这个快速教程易于阅读和理解。
