Rails 設計登錄不工作 (Rails devise sign in not working)

問題描述

Rails 設計登錄不工作 (Rails devise sign in not working)

我有一個問題 ‑ 最近我使用 devise gem 創建了用戶。可悲的是，“sign_in”按鈕並不能真正正常工作 ‑ 在訪問 sin_in 頁面並單擊登錄按鈕後沒有任何反應！如果我輸入用於登錄的電子郵件和密碼都沒關係。我檢查了日誌，單擊註冊按鈕後，日誌或運行服務器的終端上沒有任何變化！所以我猜它沒有發送任何請求？但問題只有在我第一次訪問登錄頁面後才會出現，刷新後一切正常。請幫助我，我不知道是什麼導致了這種奇怪的行為。

編輯：奇怪的是，我注意到只有在從我的主頁進入登錄頁面後才會出現問題 ‑ 如果我只是通過輸入其地址而不是單擊瀏覽器中的鏈接來進入登錄頁面，它就可以工作。但是兩個操作後的地址是一樣的，所以我不知道...有我的歡迎視圖：

<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： 應用程序控制器：

 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

遷移：

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

User.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

路由：

Rails.application.routes.draw do

  root to: 'welcome#index'
  devise_for :users

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

end

和gemfile：

參考解法

方法 1:

Looks like turbolinks problem.

1. Remove turbolinks gem from your Gemfile
2. Run bundle install
3. In app/views/layouts/application.html.haml set turbolinks to false like that:

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

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

or remove them.

1. remove //= require turbolinks from app/assets/javascripts/application.js
2. Restart server

方法 2:

"By default, all internal HTML links will be funneled through Turbolinks, but you can opt out by marking links or their parent container with data‑no‑turbolink. For example, if you mark a div with data‑no‑turbolink, then all links inside of that div will be treated as regular links. If you mark the body, every link on that entire page will be treated as regular links."

<div id="some‑div" data‑no‑turbolink> <a href="/">Home (without Turbolinks)</a> </div>
