Rails アプリケーションはローカルで正常に動作し、正常にデプロイされているようです。ルート ルートは、ウェルカム スプラッシュ ページに移動します。そのページには、次のコードによって生成された組織モデルのインデックスへのリンクがあります。

<%= link_to("Organizations", organizations_path, :class => "button_blue") %>

a2 ホスティングによってホストされている運用サーバーでそのリンクをクリックしようとすると、次のエラーが表示されます。

Started GET "/database/organizations.shtml" for 11.222.33.444 at Sat Oct 05 00:10:35 -0400 2013

ActionController::RoutingError (No route matches [GET] "/database/organizations.shtml"):
  actionpack (3.2.13) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'
  ...

開発中のように「/organizations」ではなく「/database/organizations」を取得しようとするのはなぜですか? アドレス バーの URL は " http://database.mysite.com/organizations " です。サイトがサブドメイン database.mysite.com にあるという事実と何か関係がありますか? Rails アプリにプライマリ ドメインを使用できないため、これを回避するにはどうすればよいですか?

それだけの価値があるので、実行したときに得られるものは次のとおりです

RAILS_ENV=production bundle exec rake routes | grep organization

サーバー上:

                  organizations GET    /organizations(.:format)                            organizations#index
                                POST   /organizations(.:format)                            organizations#create
               new_organization GET    /organizations/new(.:format)                        organizations#new
              edit_organization GET    /organizations/:id/edit(.:format)                   organizations#edit
                   organization GET    /organizations/:id(.:format)                        organizations#show
                                PUT    /organizations/:id(.:format)                        organizations#update
                                DELETE /organizations/:id(.:format)                        organizations#destroy

ここに私のroutes.rbがあります:

MyApp::Application.routes.draw do

  root :to => 'application#index'

  resources :grantmakers, :grant_records, :events, :organizations

end

これが私のconfig/environments/production.rbです:

MyApp::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # Code is not reloaded between requests
  config.cache_classes = true

  # Full error reports are disabled and caching is turned on
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Disable Rails's static asset server (Apache or nginx will already do this)
  config.serve_static_assets = false

  # Compress JavaScripts and CSS
  config.assets.compress = true

  # Don't fallback to assets pipeline if a precompiled asset is missed
  config.assets.compile = true

  # Generate digests for assets URLs
  config.assets.digest = true

  # Defaults to nil and saved in location specified by config.assets.prefix
  # config.assets.manifest = YOUR_PATH

  # Specifies the header that your server uses for sending files
  # config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
  # config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx

  # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
  # config.force_ssl = true

  # See everything in the log (default is :info)
  # config.log_level = :debug

  # Prepend all log lines with the following tags
  # config.log_tags = [ :subdomain, :uuid ]

  # Use a different logger for distributed setups
  # config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)

  # Use a different cache store in production
  # config.cache_store = :mem_cache_store

  # Enable serving of images, stylesheets, and JavaScripts from an asset server
  # config.action_controller.asset_host = "http://assets.example.com"

  # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
  # config.assets.precompile += %w( search.js )

  # Disable delivery errors, bad email addresses will be ignored
  # config.action_mailer.raise_delivery_errors = false

  # Enable threaded mode
  # config.threadsafe!

  # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation can not be found)
  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners
  config.active_support.deprecation = :notify

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  # config.active_record.auto_explain_threshold_in_seconds = 0.5
end

そして、ここに私のapplication_controller.rbがあります:

class ApplicationController < ActionController::Base
  protect_from_forgery

  def index
  end

  before_filter :basic_http_authentication

  private

  def basic_http_authentication
    if Rails.env.production?
      authenticate_or_request_with_http_basic do |username, password|
        username == '---' && password == '---'
      end
    end
  end
end

どうもありがとうございました。
