我有一个问题 - 最近我用devise gem创建了User。可悲的是，＆＃34; sign_in＆＃34;按钮不能正常工作 - 访问sin_in页面并点击登录按钮后没有任何反应！如果我输入用于登录的电子邮件和密码并不重要。我检查了日志，点击注册按钮后，日志或运行服务器的终端上没有任何变化！所以我猜它不会发送任何请求？但问题发生在我第一次访问登录页面后，刷新后所有工作都按预期工作。请帮助我，我不知道是什么原因导致这种奇怪的行为。
编辑：奇怪的是，我注意到只有在从我的主页面登录页面后才会出现问题 - 如果我只是通过键入地址而不是点击浏览器链接中的单词继续登录页面就可以了。但是两个动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>
有我的档案：
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

看起来像turbolinks问题。
false，如下所示： = stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => false
= javascript_include_tag 'application', 'data-turbolinks-track' => false
或删除它们。
//= require turbolinks

@JakubKopyś以下是从turbolinks中排除单链接而不删除gem的好方法（来自turbolinks github repo）：
“默认情况下，所有内部HTML链接都将通过Turbolinks进行汇总，但您可以通过使用data-no-turbolink标记链接或其父容器来选择退出。例如，如果您使用data-no-turbolink标记div ，然后该div内的所有链接都将被视为常规链接。如果您标记正文，则整个页面上的每个链接都将被视为常规链接。“
<div id="some-div" data-no-turbolink>
<a href="/">Home (without Turbolinks)</a>
</div>
