Rails 设备登录不起作用

Question

我有一个问题 - 最近我用 devise gem 创建了用户。遗憾的是，“sign_in”按钮并没有真正正常工作 - 访问 sin_in 页面并单击“sign in”按钮后没有任何反应！如果我输入电子邮件和密码进行登录并不重要。我检查了日志，单击注册按钮后，日志中或运行服务器的终端上没有任何更改！所以我猜它不会发送任何请求？但问题仅在我第一次访问登录页面后出现，刷新后一切按预期工作。请帮助我，我不知道什么可能会导致这种奇怪的行为。

编辑：奇怪的是，我注意到只有在从主页前往登录页面后才会出现问题 - 如果我只需输入其地址而不是单击浏览器中的链接来进入登录页面，它就会起作用。但是两个操作之后的地址是相同的，所以我不知道......有我欢迎的观点：

<div id="homepage">
  <header class="cf">
    <h1 class="logo"><%= link_to "E-LEARN", "#" %></h1>
    <nav>
      <ul>
        <li><%= link_to "Watch guides", root_path %></li>
        <% unless user_signed_in? %>
          <li><%= link_to "Log In", new_user_session_path %></li>
        <% else %>
          <li><%= link_to "Log Out", destroy_user_session_path, method: :delete %></li>
          <li><%= link_to "Settings", edit_user_registration_path %></li>
          <li><%= link_to "My Account", current_user %></li>
        <% end %>
        <li><%= link_to "Add tutorial", "#" %></li>
      </ul>
    </nav>
  </header>
  <div class="wrapper-skinny" id="welc">
    <h1>Learn programming from others, or share your experience with novices.</h1>
  </div>
  <div class="buttons">
    <%= link_to "Learn something", new_user_registration_path , class: "button button-highlight" %>
    <%= link_to "Share experience", "#", class: "button button-dark"%>
  </div>
</div>

有我的文件：
应用程序控制器：

 class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
  before_filter :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:username, :description, :email, :password, :password_confirmation, :current_password) }
  end
end

移民：

class DeviseCreateUsers < ActiveRecord::Migration
  def change
    create_table(:users) do |t|
      ## Database authenticatable
      t.string :email,              null: false, default: ""
      t.string :encrypted_password, null: false, default: ""

      ## Recoverable
      t.string   :reset_password_token
      t.datetime :reset_password_sent_at

      ## Rememberable
      t.datetime :remember_created_at

      ## Trackable
      t.integer  :sign_in_count, default: 0, null: false
      t.datetime :current_sign_in_at
      t.datetime :last_sign_in_at
      t.string   :current_sign_in_ip
      t.string   :last_sign_in_ip

      ## Confirmable
      # t.string   :confirmation_token
      # t.datetime :confirmed_at
      # t.datetime :confirmation_sent_at
      # t.string   :unconfirmed_email # Only if using reconfirmable

      ## Lockable
      # t.integer  :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts
      # t.string   :unlock_token # Only if unlock strategy is :email or :both
      # t.datetime :locked_at


      t.timestamps null: false
    end

    add_index :users, :email,                unique: true
    add_index :users, :reset_password_token, unique: true
    # add_index :users, :confirmation_token,   unique: true
    # add_index :users, :unlock_token,         unique: true
  end
end

用户.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  has_many :guides
  validates :username, presence: true, length: { minimum: 5 }
end

路线：

Rails.application.routes.draw do

  root to: 'welcome#index'
  devise_for :users

  resources :users, only: [:show, :index] do
    resources :guides
  end

end

Answer 1

看起来像涡轮链接问题。

1. 从 Gemfile 中删除 Turbolinks gem
2. 运行捆绑安装
3. 在 app/views/layouts/application.html.haml 中将 Turbolinks 设置为false这样：

= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => false

= javascript_include_tag 'application', 'data-turbolinks-track' => false

或删除它们。

4. //= require turbolinks从 app/assets/javascripts/application.js 中删除
5. 重启服务器
