Question

我正在关注有关rails的设计和cancan集成的教程。 https://github.com/RailsApps/rails3-bootstrap-devise-cancan 我注意到当用户登录闪存通知时会导致页面在关闭后重新加载。我在日志中看到了这一点：重定向到“根路径”已完成302

这是我的路线文件

App::Application.routes.draw do

resources :videos do
collection do
  post "delete_selected_item"
 end
end

unauthenticated do
  root :to => 'external#index'
  match '/features' => 'external#features'
  match '/pricing' => 'external#pricing'
end

devise_scope :user do
  match '/sign_up' => 'devise/registrations#new'
  match '/sign_in' => 'devise/sessions#new'
end

devise_for :users

authenticated :user do
  root :to => "dashboard#index"
  match 'dashboard/videos' => 'videos#index'
  match 'dashboard/statistics' => 'statistics#index'
  match 'dashboard/analytics' => 'analytics#index'
  resources :users
end

post "zencoder-callback" => "zencoder_callback#create", :as => "zencoder_callback"

end

布局代码：

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title><%= content_for?(:title) ? yield(:title) : "BriteVid" %></title>
<meta name="description" content="<%= content_for?(:description) ? yield(:description) :  "BriteVid" %>">
<meta name="csrf-token" content="<%= form_authenticity_token %>" />
<meta name="csrf-param" content="authenticity_token" />
<%= stylesheet_link_tag "application", :media => "all" %>

<%= javascript_include_tag "application" %>
<link href="<%= image_path("favicon.ico") %>" rel="shortcut icon" />
<%= csrf_meta_tags %>
<%= yield(:head) %>
</head>

<body class="<%=params[:controller].parameterize%> <%=params[:action].parameterize%>">

<div class="navbar navbar-inverse navbar-fixed-top">
 <div class="navbar-inner">
   <div id="nav_header">
    <%= render 'dashboard/internal_header' %>
   </div>
  </div>
</div>
<%= render 'layouts/shared/alerts' %>
  <div id="wrap">
  <div id="main" role="main">
  <%= render 'dashboard/dashnav' %>
     <%= yield %>
     <% if Rails.env.production? %>  <%= render 'layouts/shared/ga' %><% end %> 
   </div>
 </div>
<%= render 'layouts/shared/chat' %>
</body>

</html>

Flash消息代码

<div class="container">
  <% if user_signed_in? %>
    <% flash.each do |name, msg| %>
      <div class="alert-<%= name == :notice ? "success" : "error" %> fade in">
      <a class="close" data-dismiss="alert" href="">x</a>
      <center><%= content_tag :div, msg, :id => "flash_#{name}" %></center>
    </div>
  <% end %>
 <% end %>
</div>

Answer 1

更改此

<a class="close" data-dismiss="alert" href="">x</a>

到这个

<a class="close" data-dismiss="alert" href="#">x</a>

现在，该页面将不再重定向到根网址。

<强> [编辑]

href=""标记中的空<a>重新加载页面。所以，您可以将其更改为以下内容：

href="#"在浏览器历史记录中添加了一个额外的条目（例如，在回扣时很烦人）。
href="javascript:;"似乎没有任何问题（除了看起来凌乱无意义）

Answer 2

您确定正确包含bootstrap javascript文件吗？

在application.js中应该是那一行：

//= require bootstrap

关闭Flash通知导致页面重定向
