Question

我遇到以下问题：当我转到http://lvh.me:3000或http://www.lvh.me:3000时，我收到此错误：

无法找到子域名为
的商店
app / controllers / application_controller.rb：8：在`set_current_store'

使用子域名，效果很好（如果我转到http://store.lvh.me，它会完美运行。只有根不起作用）。

这是我的代码：

url_helper.rb

module UrlHelper
  def with_subdomain(subdomain)
    subdomain = (subdomain || "")
    subdomain += "." unless subdomain.empty?
    [subdomain, request.domain].join
  end
end

application_controller.rb

class ApplicationController < ActionController::Base
  before_filter :set_current_store
  include UrlHelper
  protect_from_forgery

  private
    def set_current_store
      @current_store = Store.find_by_subdomain!(request.subdomains.first)
    end
end

的routes.rb

  resources :stores

  constraints(Subdomain) do
    match '/' => "stores#show"
    resources :stores
    resources :pages, path: "strani"
  end

  root to: "stores#index"

subdomain.rb

class Subdomain
  def self.matches?(request)
    request.subdomain.present? && request.subdomain != "www"
  end
end

Answer 1

删除!上的爆炸find_by_subdomain并提供默认子域

e.g：

@current_store = Store.find_by_subdomain(request.subdomains.first) || default_subdomain

无法找到存储子域名=的商店
