Ruby on rails Facebook omniauth登录上的多个Rails应用程序路由问题

我目前正在维护一个Rails项目，该项目需要将其乘客机架中间件切换到Unicorn。我遇到了一个问题，Unicorn似乎不太支持子域，所以我有一个如下的解决方法

require_relative '../lib/route_scoper'

MyProject::Application.routes.draw do
  scope RouteScoper.root do
    get "pages/welcome"

    mount RailsAdmin::Engine => '/admin', as: 'rails_admin'

    devise_for :users, controllers: { omniauth_callbacks: "omniauth_callbacks" }

    root to: "pages#welcome"

    resources :categories, only: [:index, :show]
    resources :counties, only: [:index], defaults: { format: :json }
    resources :products, only: [:show] do
      resources :votes, only: [:create]
    end

    resources :tickets, only: [:new, :create]
  end
end

根据这篇文章，我做了一个变通办法

一切正常，除了我们的Facebook登录似乎有路由问题

Started GET "/my_project"
Processing by Devise::CasSessionsController#service as HTML
Redirected to http://events.staging.mainsite/users/auth/facebook
Filter chain halted as :sync_fb_user rendered or redirected
Completed 302 Found in 49.8ms (ActiveRecord: 0.0ms)

Rails项目的域名如下

http://events.staging.mainsite/my_project

它总是将我重定向到

http://events.staging.mainsite/users/auth/facebook

页面显示未找到错误消息404

它用于在旧版本的URL处进行路由，如下所示

Redirected to /my_project/users/auth/facebook

我不确定是否可以覆盖omniauth路径来修复此问题，或者只是修改

路由.rb

以指向正确的登录路径，谢谢您的帮助。

我刚刚解决了这个问题，我必须为我的设备添加一个路径 然后将其移出RouteScope

devise_for :users, controllers: { omniauth_callbacks: "omniauth_callbacks" }, path: "#{RouteScoper.root}/users"
