ruby-on-rails – 如何创建管理子域以管理Rails中的子域

我使用的是AuthLogic和 this blog post中涵盖的子域方法,一切都运行良好,并且符合预期.我想弄清楚的是如何创建一个像“admin”或“host”这样的子域,它将使用AuthLogic进行身份验证的用户(这可能是微不足道的,无需提及)来管理子域.基本上,所有子域都将正常运行,除了admin.site.com,它将转到自己的控制器和布局.

dhh建议只是引入一个例外来重定向,但是我不确定那里发生了什么,对我来说这似乎不是很简单,任何想法？

编辑
我认为我使用AuthLogic的事实在这里非常重要,因为子域逻辑不会在任何地方转发用户,一旦经过身份验证,AuthLogic会将用户发送到/ account – 所以我的问题可能与如何告知AuthLogic不同的地点有关user是root用户,登录admin子域.

这是我们迄今为止实现的代码

Company Model

class Company < ActiveRecord::Base
  has_many :users
  has_many :brands, :dependent => :destroy

  validates_presence_of     :name, :phone, :subdomain
  validates_format_of       :subdomain, :with => /^[A-Za-z0-9-]+$/, :message => 'The subdomain can only contain alphanumeric characters and dashes.', :allow_blank => true
  validates_uniqueness_of   :subdomain, :case_sensitive => false
  validates_exclusion_of    :format, :in => %w( support blog billing help api www host admin manage ryan jeff allie), :message => "Subdomain {{value}} is not allowed."
  before_validation         :downcase_subdomain

  protected
    def downcase_subdomain
      self.subdomain.downcase! if attribute_present?("subdomain")
    end
end

SubdomainCompanies Module

module SubdomainCompanies
  def self.included( controller )
    controller.helper_method(:company_domain, :company_subdomain, :company_url, :company_account, :default_company_subdomain, :default_company_url)
  end

  protected

    # TODO: need to handle www as well
    def default_company_subdomain
      ''
    end

    def company_url( company_subdomain = default_company_subdomain, use_ssl = request.ssl? )
      http_protocol(use_ssl) + company_host(company_subdomain)
    end

    def company_host( subdomain )
      company_host = ''
      company_host << subdomain + '.'
      company_host << company_domain
    end

    def company_domain
      company_domain = ''
      company_domain << request.domain + request.port_string
    end

    def company_subdomain
      request.subdomains.first || ''
    end

    def default_company_url( use_ssl = request.ssl? )
      http_protocol(use_ssl) + company_domain
    end      

    def current_company
      Company.find_by_subdomain(company_subdomain)
    end

    def http_protocol( use_ssl = request.ssl? )
      (use_ssl ? "https://" : "http://")
    end 
end

Application Controller

class ApplicationController < ActionController::Base
  include SubdomainCompanies

  rescue_from 'Acl9::AccessDenied', :with => :access_denied

  helper :all # include all helpers, all the time
  protect_from_forgery # See ActionController::RequestForgeryProtection for details
  helper_method :current_user_session, :current_user, :current_company_name
  filter_parameter_logging :password, :password_confirmation 
  before_filter :check_company_status

  protected

    def public_site?
      company_subdomain == default_company_subdomain
    end

    def current_layout_name
      public_site? ? 'public' : 'login'
    end

    def check_company_status
      unless company_subdomain == default_company_subdomain
        # TODO: this is where we could check to see if the account is active as well (paid, etc...)
        redirect_to default_company_url if current_company.nil? 
      end
    end
end

查看 subdomain-fu,它允许您根据子域路由到不同的控制器和操作.关于这个问题我做了 Railscasts Episode.

它可能看起来像这样.

# in routes.rb
map.manage_companies '', :controller => 'companies', :action => 'index', :conditions => { :subdomain => "admin" }

这需要在路由列表中足够高,以便在它之前没有其他匹配.
