这是我的错误
ActionView::Template::Error (Devise could not find the
Warden::Proxyinstance on your request environment.
Make sure that your application is loading Devise and Warden as expected and that theWarden::Managermiddleware 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::ControllerHelpersmodule to inject therequest.env['warden']object for you.)
1: -if user_signed_in?
2: .ui.popup.computer{id:”post#{post.id}user#{post.user.id}”,style:”padding:0px”}
3: .ui.card
4: .image
我不知道该怎么办
请帮帮我.
解决方法
在ApplicationController中定义renderer_with_signed_in_user类方法.
class ApplicationController < ActionController::Base
...
def self.renderer_with_signed_in_user(user)
ActionController::Renderer::RACK_KEY_TRANSLATION['warden'] ||= 'warden'
proxy = Warden::Proxy.new({},Warden::Manager.new({})).tap { |i|
i.set_user(user,scope: :user,store: false,run_callbacks: false)
}
renderer.new('warden' => proxy)
end
...
end
然后你可以从Rails应用程序的其他部分渲染,如下所示：
renderer = ApplicationController.renderer_with_signed_in_user(user)
renderer.render template: 'notifications/show',layout: false,locals: { foo: 'bar' }
