ruby-on-rails - 登录后将用户定向到各自的子域

Question

我的用户能够注册该应用程序并被定向到他们在屏幕中键入的相应子域。我希望在重新登录时将它们重定向回同一个子域。我没有收到任何错误，但是当我重新登录系统时，不会在 url 前面插入子域。

application_controller.rb

skip_before_action :verify_authenticity_token
def after_sign_in_path_for(resource_or_scope)
   root_url(:subdomain => resource.subdomain) 
end 

def after_sign_out_path_for(resource_or_scope)
  root_url(subdomain: false)
end 

路线.rb

class SubdomainPresent
  def self.matches?(request)
    subdomains = %w{ www admin }
    request.subdomain.present? && !subdomains.include?(request.subdomain)
  end
end

class SubdomainBlank
   def self.matches?(request)
    request.subdomain.blank?
   end
end

Rails.application.routes.draw do

resources :accounts
devise_for :users, controllers: { registrations: 'accounts', sessions: 'sessions' } 
get 'contact-us', to: 'contacts#new', as: 'new_contact'

constraints(SubdomainBlank) do
    root 'visitors#new'
    get 'about', to: 'pages#about'
    get 'services', to: 'pages#services'
    resources :contacts, only: :create
    resources :visitors, only: [:new, :create]
end 

constraints(SubdomainPresent) do
    root 'tasks#index', as: :subdomain_root
    resources :users do
      resource :profile
    end
    resources :tasks
    resources :deals
    resources :companies
end

end
