Ruby on Rails Devise编辑注册路由错误

Question

我正在使用Ruby 2.0.0和Rails 4.0.2。 当我单击“编辑配置文件”页面上的“提交”按钮时，出现以下路由错误：

路由错误

没有路由匹配[PATCH]“ / users / sign_in”

我不完全了解devise路由的工作方式，因为我看到的route.rb文件中唯一相关的行是devise_for：users。 这是我的一些文件。 谢谢。

/config/routes.rb

SampleApplication::Application.routes.draw do

  resources :pins

  devise_for :users

  root 'pages#home'
  get 'about' => 'pages#about'
  get 'contact' => 'pages#contact'

end

/models/user.rb

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable, #:recoverable, 
        :rememberable, :trackable, :validatable

  has_many :pins
end

/views/devise/registrations/edit.html.erb

<h2>Edit <%= resource_name.to_s.humanize %></h2>

<%= simple_form_for(resource, :as => resource_name, :url => session_path(resource_name), html:          {class: 'form-horizontal'}) do |f| %>

  <%= f.error_notification %>

  <%= f.input :password, label: "New Password", autocomplete: "off" %>
  <%= f.input :password_confirmation, label: "New Password", autocomplete: "off" %>
  <%= f.input :current_password %>

  <div class="form-actions">
    <%= f.submit "Update", class: "btn btn-primary"%>
  </div>
<% end %>

<h3>Cancel my account</h3>

<p>Unhappy? <%= link_to "Cancel my account", registration_path(resource_name), :confirm => "Are      you sure?", :method => :delete %>.</p>

<%= link_to "Back", :back %>

您的simple_form指向错误的提交URL。

它说

<%= simple_form_for(resource, :as => resource_name, :url => session_path(resource_name), html:          {class: 'form-horizontal'}) do |f| %

但url应指向user_registration_path ，而不是session_path ，因此

<%= simple_form_for(resource, :as => resource_name, :url => user_registration_path(resource_name), html:          {class: 'form-horizontal'}) do |f| %
