Question

当我尝试注册我的应用程序时，我一直收到此错误，我正在使用设计进行身份验证;

    NoMethodError in Devise::Registrations#new


undefined method `registration_path' for #<#<Class:0x007fe45c6c35e8>:0x007fe45d9ffd78>
Extracted source (around line #3):

  <h2>Sign up</h2>

  <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
    <%= devise_error_messages! %>

    <div><%= f.label :email %><br />

当我运行rake routes时，我得到了;

                  Prefix Verb   URI Pattern                    Controller#Action
        new_user_session GET    /users/sign_in(.:format)       devise/sessions#new

                         PUT    /users(.:format)               devise/registrations#update
                         DELETE /users(.:format)               devise/registrations#destroy

注册链接代码;

<%= link_to "Sign up", new_user_registration_path%>

更新感谢ParaPenguin，注册字段现在可以正常工作，但是当我点击提交时，我不断遇到这个问题

No route matches [POST] "/users/sign_up"

    new_user_session_path    GET     /users/sign_in(.:format)    devise/sessions#new
user_session_path    POST    /users/sign_in(.:format)    devise/sessions#create
destroy_user_session_path    DELETE  /users/sign_out(.:format)   devise/sessions#destroy
user_password_path   POST    /users/password(.:format)   devise/passwords#create

PATCH    /users(.:format)    devise/registrations#update
PUT  /users(.:format)    devise/registrations#update
DELETE   /users(.:format)

更新2-Gjaldon要求我包含我的用户模型和路线 我的用户模型

    class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
end

的routes.rb

Document::Application.routes.draw do
  devise_for :users
   root "pages#home"
  get "about" => "pages#about"
   get "prices" => "pages#prices"
  get "faq" => "pages#faq", :as => :faq
  get "terms" => "pages#terms"
  get "view" => "pages#view"
  get "policy" => "pages#policy"
  get "contact" => "pages#contact"
  get "works" => "pages#works"

Answer 1

您可以在routes.rb中提供Devise的路线以及您的用户模型的设计代码吗？

以下任一项可能会解决您的问题：

重新启动Rails服务器。这样，Rails就会看到新文件和Devise对Rails所做的更改。
您是否覆盖了Devise :: Registrations＃new action？如果是这样，您需要更换以下视图代码：

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>

使用：

<%= form_for(resource, :as => resource_name, :url => user_registration_path) do |f| %>

在devise_registrations/edit.html.erb视图中，您的form_for代码如下所示：

<%= form_for(resource, :as => resource_name, :url => edit_user_registration_path(resource_name, :method => :put) do |f| %>

您的rake routes实际上为您提供了您需要提交的路线。请记住，相应的控制器和操作显示在rake routes输出中的Controller＃action列下。 edit操作中的表单应始终提交到update操作，如果您坚持使用Rails约定，则new操作中的表单应始终提交到create操作。如果您决定在另一个操作中创建表单以创建记录，请确保将表单提交给create操作。

Answer 2

尝试从

更改registration_path(resource_name)

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>

到new_registration_path(resource_name)。这可以解决错误，但我不确定，这是可能的。它似乎只适合你，因为文件设置对我的设计来说运行得很好。
