设计中没有方法错误::注册#new [英] NoMethodError in Devise::Registrations#new

问题描述

当我尝试注册我的应用程序时，我不断收到此错误，我正在使用 devise 进行身份验证；

I keep getting this error when I try to sign up on my application, I am using devise for authentication;

    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；

When I run rake routes I get;

                  Prefix Verb   URI Pattern                    Controller#Action

                         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，注册字段现在可以使用了，但是当我点击提交时，我不断遇到这个问题

UPDATE Thanks to ParaPenguin the sign up field works now, but when I click submit I keep getting this problem

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

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"

推荐答案

你能否在你的 routes.rb 中提供你的设计路线和你的用户模型的设计代码?

Could you provide your routes for Devise in your routes.rb and the devise code for your User model?

以下任一方法可能会解决您的问题:

It's either one of the following that might fix your problem:

1. 重启你的 Rails 服务器.这样，Rails 就会看到 Devise 对 Rails 所做的新文件和更改.

1. Restart your Rails server. This way, Rails will see the new files and changes Devise has made to Rails.

您是否覆盖了 Devise::Registrations#new 操作?如果是这样，您需要替换下面的视图代码:

Did you override the Devise::Registrations#new action? If so, you will need to replace your view code below:

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

与:

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

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

In your devise_registrations/edit.html.erb view, your form_for code would look like:

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

你的 rake 路由 实际上为你提供了你需要提交的路由.请记住，相应的控制器和动作显示在 rake routes 输出的 Controller#action 列下.edit 操作中的表单应始终提交给 update 操作，new 操作中的表单应始终提交给 create action 如果你坚持 Rails 约定.如果您决定在另一个操作中使用表单来创建记录，请确保将表单提交给 create 操作.

Your rake routes actually provides you with the routes you need to submit to. Just keep in mind that the corresponding controller and action is displayed under the Controller#action column in the output of rake routes. The form in edit action should always submit to the update action and the form in new action should always submit to the create action if you stick to the Rails conventions. If you decide to have a form in another action for creating a record, then make sure to have the form submit to the create action.
