ruby-on-rails - 如何使用 Rails 5 中的 Application.renderer.render 和设计

Question

我想实时制作我的应用程序

这是我的错误

ActionView::Template::Error (Devise could not find the Warden::Proxy instance on your request environment. Make sure that your application is loading Devise and Warden as expected and that the Warden::Manager 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 the Devise::Test::ControllerHelpers module to inject the request.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。

我想我为我的情况找到了解决方案。

定义 renderer_with_signed_in_user ApplicationController 中的类方法.

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

然后您可以从 Rails 应用程序的其他部分进行渲染，如下所示:

renderer = ApplicationController.renderer_with_signed_in_user(user)
renderer.render template: 'notifications/show', layout: false, locals: { foo: 'bar' }
