Question

我已在我的引擎上安装了设备并在application.html.erb文件中应用了以下内容：

<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>

它显示No route matches "/users/sign_out"并显示

的错误

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

错误讯息NameError in Devise::Sessions#new

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

引擎路线：

Fd::Engine.routes.draw do
devise_for :users,:controllers => { :omniauth_callbacks => "omniauth_callbacks" }, :class_name => "Fd::User", module: :devise
end

Answer 1

试试这个：

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

并确保您的config/initializers/devise.rb

下面有一行

config.sign_out_via = :get

Answer 2

你在设计中集成了OmniAuth，所以如果用户提供正确的凭证，设计会创建会话，从你的问题我理解会话已成功创建，所以如果你想要清除会话只是在控制器中创建一个动作（你开始会话）并给

redirect_to "/users/sign_out"

或

尝试

redirect_to destroy_user_session_path

我希望这会起作用

Rails设计引擎Sign_out链接错误
