Ruby 在 Rails Devise 上 - 无法注销

Question

我对 Rails (v4.0.0) 和 Devise (v3.5.2) 上的 Ruby (v2.0.0) 有点陌生，出于某种原因，我无法退出已注册。但是，如果我手动进入 MySQL2 数据库并完全删除用户，我的 Sign Up/Sign In 页面将再次可用。

我没有触及我的 session_store.rb 初始值设定项或其他任何东西。我陷入困境，需要先解决这个问题，然后才能继续前进。

非常感谢帮助。

我的注册表单的逻辑非常简单：

<% if user_signed_in? %>
    <%= current_user.email %> / <%= link_to "Sign Out", destroy_user_session_path, method: :delete %>
<% else %>
    <%= link_to "Sign Up", new_user_registration_path %> / <%= link_to "Log In", new_user_session_path %>
<% end %>

我的devise.rb文件也配置为使用:delete :

config.sign_out_via = :delete

我的 Gemfile 中有 JQuery:

# jQuery
gem 'jquery-rails'
gem 'jquery-ui-rails'

我在 application.js:

中对它们进行了初始化

//= require jquery
//= require jquery_ujs
//= require jquery.ui.all
//= require jquery.details
//= require jquery.textchange

我的routes.rb配置正确（注释掉的“#devise_for :users”说明两种方法我都试过了，none 有效）：

Selfstarter::Application.routes.draw do
root :to => 'home#index'
  #devise_for :users
  devise_for :users do
  get '/users/sign_out' => 'devise/sessions#destroy'
  end
...
end

我的 rake routes 反映了：

                  Prefix Verb     URI Pattern                     Controller#Action
                    root GET      /                               home#index
        new_user_session GET      /users/sign_in(.:format)        devise/sessions#new
            user_session POST     /users/sign_in(.:format)        devise/sessions#create
    destroy_user_session DELETE   /users/sign_out(.:format)       devise/sessions#destroy
           user_password POST     /users/password(.:format)       devise/passwords#create
       new_user_password GET      /users/password/new(.:format)   devise/passwords#new
      edit_user_password GET      /users/password/edit(.:format)  devise/passwords#edit
                         PATCH    /users/password(.:format)       devise/passwords#update
                         PUT      /users/password(.:format)       devise/passwords#update
cancel_user_registration GET      /users/cancel(.:format)         devise/registrations#cancel
       user_registration POST     /users(.:format)                devise/registrations#create
   new_user_registration GET      /users/sign_up(.:format)        devise/registrations#new
  edit_user_registration GET      /users/edit(.:format)           devise/registrations#edit
                         PATCH    /users(.:format)                devise/registrations#update
                         PUT      /users(.:format)                devise/registrations#update
                         DELETE   /users(.:format)                devise/registrations#destroy

user.rb 型号：

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

database.rb 以防万一：

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: dbname
  pool: 5
  username: dbusername
  password: dbpass
  #socket: /opt/local/var/run/mysql5/mysqld.sock

我不知道接下来要采取什么步骤，并且搜索了 Google 和 Stack Overflow。我什么也没找到。

我还想提一下，我真的很想遵守 RESTful 约定，并且尽可能不使用 :get 方法。

Answer 1

我终于找到了解决办法。我只需要将 <%= csrf_meta_tags %> 添加到我的 application.html.erb header 标签中，它就像一个魅力。
