ruby-on-rails – Rails 4子域不适用于生产

开发领域：

> mydomain.dev
> api.mydomain.dev
> account.mydomain.dev

生产域(Ngnix with Passenger)：

> app.mydomain.com(www.mydomain.com和mydomain.com显示其他页面,而不是应用程序)
> api.mydomain.com
> account.mydomain.com

我的config / routes.rb看起来像这样：

Rails.application.routes.draw do
    namespace :api,constraints: { subdomain: 'api' },path: '/',defaults: { format: :json } do
        namespace :v1 do
            resources :clients,only: [:create,:show]
        end
    end

    namespace :account,constraints: { subdomain: 'account' },path: '/' do
        get '/:locale' => 'welcome#index',locale: /en|pt/
        root 'welcome#index'

        scope "(:locale)",locale: /en|pt/ do
            get :sign_in,to: 'sessions#new'
            post :sign_in,to: 'sessions#create'
        end
    end

    get '/:locale' => 'welcome#index',locale: /en|pt/
    root 'welcome#index'

    scope "(:locale)",locale: /en|pt/ do
        resource :session,only: [:new,:create,:destroy]
        get :login,to: 'sessions#new',as: :login
    end
end

我的ngnix虚拟主机文件：

server {
    listen 80;
    listen [::]:80;

    # SSL configuration
    #
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name mydomain.com api.mydomain.com account.mydomain.com;

    passenger_enabled on;
    passenger_ruby /home/username/.rvm/gems/ruby-2.2.2@myapp/wrappers/ruby;

    root /var/sites/mydomain.com/current/public;

    ssl on;
    ssl_certificate /etc/nginx/ssl/mydomain.com/server.crt;
    ssl_certificate_key /etc/nginx/ssl/mydomain.com/server.key;
}

问题是,在我的开发机器(localhost)或开发环境中,它的工作非常好,正如我想的那样.但在生产中我得到了错误：“您正在寻找的页面不存在.”,使用此日志信息：

参观：https://account.mydomain.com/en/sign_in

在其他作品中,account.mydomain.com和api.mydomain.com仍然充当我的主域“mydomain.com”(作为同一个域).

更新：

我在我的页面上添加了这个代码：

<%= request.domain.inspect %><br>
<%= request.subdomain.inspect %>

访问：http://api.mydomain.co.ao
结果我得到了：

As Domain: “co.ao”

As Subdomain: “api.mydomain”

但我的子域名只有：api

怎么了？
