嗨,我使用设计我的用户身份验证
我已经按照各种教程在弹出窗口中获取登录但是我没有成功,任何人都可以告诉我们如何详细说明.我已经尝试了各种教程,但没有任何工作,每一件事都重定向到登录页面.
我是铁路的新手请帮忙.
这是我的new.html.erb
<%= form_for(:user,:html => {:id => 'login_form'},:url => user_session_path,:remote => :true,:format => :json) do |f| %> <%= f.email_field :email,:autofocus => true,:placeholder => "email",:id => 'login_email' %> <%= f.password_field :password,:placeholder => "password",:id => 'login_password' %> <% if devise_mapping.rememberable? -%> <div><%= f.check_Box :remember_me %> <%= f.label :remember_me %></div> <% end -%> <div><%= image_submit_tag('modals/account/login_submit.png') %></div> <% end %>
<% if user_signed_in? %> <p>Welcome <%= current_user.email %></p> <%= link_to "Sign out",destroy_user_session_path,:method => :delete %> <% else %> <p>You are not signed in.</p> <%= link_to "Sign in",new_user_session_path,:remote => :true %> <% end %>
解决方法
首先,你想要
pop-up or a pop-over吗?
弹出窗口是新的Windows,让人想起90年代的广告,而弹出式窗口(有时称为模态)是UI中的集成元素,基本上只是黑暗背景上的div
所有Web 2.0站点都使用弹出窗口来增强可用性,而弹出窗口则会减损体验:)

我们已经实现了您所寻求的功能(点击this development site顶部的“登录”)
你需要做好几件事才能完成这项工作 – 我会在这里为你详细说明:
路线
#config/routes.rb devise_for :users,:path => '',:controllers => {:sessions => 'sessions',:registrations => 'registrations'},:path_names => { :sign_in => 'login',:password => 'forgot',:confirmation => 'confirm',:unlock => 'unblock',:registration => 'register',:sign_up => 'new',:sign_out => 'logout'}
第一步是对您的路线进行排序
虽然Devise有good routing documentation,但您需要自定义路由以包含自定义会话/注册控制器,以及您想要的任何自定义路径
路线中最重要的部分是(你需要自定义控制器!):
:controllers => {:sessions => 'sessions',:registrations => 'registrations'}
控制器
接下来,您需要向会话和注册控制器添加ajax响应功能.即使Devise在每次安装时添加了这些控制器,它们仍然是隐藏的,如果你想添加功能,你必须扩展它们
这是我们的会议和注册控制器(可删除此代码的许多内容,但它现在适用于我们):

使用Javascript
最后,您只需要能够处理来自Ajax的响应:
//app/assets/javscripts/application.js $(document).on('submit','#login_form',function(e) { //do stuff here }).on('ajax:success',function(e,data,status,xhr) { //do stuff here }).on('ajax:error',xhr) { //do stuff here });
