Rails的设计引擎SIGN_OUT链接错误

Question

我已经安装在我的引擎装置和后加在我application.html.erb文件中的以下内容：

<div id="user_nav"> 
    <% if user_signed_in? %> 
     Signed in as <%= current_user.email %>. This cannot be cheese? 
     <%= link_to "Sign out", destroy_user_session_path, :method => :delete %> 
    <% else %> 
     <%= link_to 'Register', new_user_registration_path %> or <%= link_to 'Sign in', new_user_session_path %> 
    <% end %> 
</div> 

这表明No route matches "https://stackoverflow.com/users/sign_out"，它显示了

<%= link_to 'Register', new_user_registration_path %> or <%= link_to 'Sign in', new_user_session_path %> 

错误

错误消息NameError in Devise::Sessions#new

undefined local variable or method `destroy_user_session_path' for #<#<Class:0x007fb4da2e9618>:0x007fb4da2db9a0>

Answer 1

您综合OmniAuth在设计，所以如果用户提供了正确的凭据设计将创建会话，从你的问题我理解会话创建成功，所以如果你想清楚会议刚刚创建的控制器（你启动会话）一个动作，并给

redirect_to "https://stackoverflow.com/users/sign_out" 

或

尝试

redirect_to destroy_user_session_path 

我希望这将工作

Answer 2

试试这个：

<%= link_to "Sign out", destroy_user_session_path, :method => :get %> 

，并确保你有下面一行在你config/initializers/devise.rb

config.sign_out_via = :get
