我尝试将Devise用于我的Rails应用程序.我可以注册并登录但是当我转到我的其他页面“构建”时,我收到以下错误：
Devise::MissingWarden in Home#show Devise could not find the
Warden::Proxy@H_403_6@ instance on your request environment. Make sure that
your application is loading Devise and Warden as expected and that the
Warden::Manager@H_403_6@ middleware is present in your middleware stack. If
you are seeing this on one of your tests,ensure that your tests are
either executing the Rails middleware stack or that your tests are
using theDevise::Test::ControllerHelpers@H_403_6@ module to inject the
request.env['warden']@H_403_6@ object for you.
这是我的控制器：
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
private
# Overwriting the sign_out redirect path method
def after_sign_out_path_for(resource_or_scope)
build_path
end
end
这是我的两个部分观点：
<!-- views/devise/menu/_login_items.html.erb -->
<% if user_signed_in? %>
<li>
<%= link_to('logout',destroy_user_session_path,:method => :delete) %>
</li>
<% else %>
<li>
<%= link_to('Login',new_user_session_path) %>
</li>
<% end %>
和
<!-- views/devise/menu/_registration_items.html.erb -->
<% if user_signed_in? %>
<li>
<%= link_to('Edit registration',edit_user_registration_path) %>
</li>
<% else %>
<li>
<%= link_to('Register',new_user_registration_path) %>
</li>
<% end %>
调试之后,我发现问题来自我的“show”控制器中的这一行：template = HomeController.render(‘layouts / _template’)
谢谢你的帮助.
