 没有路由匹配[POST]/ users / sign_up

更新2-Gjaldon要求我添加我的用户模型和路线
我的用户模型

  class User< ActiveRecord :: Base 
＃包含默认设计模块。其他可用的是：
＃：confirmable，：lockedable，：timeoutable和：omniauthable 
 devise：database_authenticatable，：可注册，
：可恢复，可记忆，可追溯，可验证
结束
  

Routes.rb

  Document :: Application.routes.draw do 
 devise_for：users 
 rootpages＃home
 getabout=> page＃about
 getprices=> pages＃prices
 getfaq=> page＃faq，：as => ：faq 
 getterms=> pages＃terms
 getview=> pages＃view
 getpolicy=> pages＃policy
 getcontact=> pages＃contact
 getworks=> page＃works
  

解决方案

设计您的路线和您的用户模型的设计代码？

以下可能会解决您的问题：

1. 重新启动Rails服务器。这样，Rails将会看到Devise已经对Rails做出的新文件和更改。




2. 你是否覆盖了Devise ::注册＃新操作？如果是这样，您将需要更换下面的视图代码：

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

with：

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

在您的 devise_registrations / edit.html.erb view，您的form_for代码将如下所示：

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

您的 rake路线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控制器＃操作列中 rake路线的输出。编辑操作中的表单应始终提交给更新操作和新表单操作应始终提交到创建操作，如果您坚持Rails约定如果您决定在创建记录的另一个操作中使用表单，请确保将表单提交到创建操作。

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>

When I run rake routes I get;

Sign up link code;

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

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

DELETE   /users(.:format)   

Update 2-Gjaldon asked me to include my user model and routes My user model

    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"

解决方案

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

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

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

2. 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| %>

with:

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

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| %>

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.
