私は sitemap_generator ( https://github.com/kjvarga/sitemap_generator ) gem を使用しており、開発環境ではコードが正常に動作しているように見えますが、本番環境で実行しようとすると、次のエラーが発生します。

private method `split' called for nil:NilClass

これは実稼働環境 (私のマシンと実稼働サーバーの両方) でのみ発生し、開発ではすべて正常に動作します。config/sitemap.rb にある私のサイト マップ コードは次のとおりです。

SitemapGenerator::Sitemap.default_host = "https://www.mysite.com"
SitemapGenerator::Sitemap.create do
  # The root path '/' and sitemap index file are added automatically for you.
  # Links are added to the Sitemap in the order they are specified.

本番環境で rake タスクを実行すると、上記のエラーが発生します。スタック トレース全体を次に示します。

これを引き起こす生産と開発の間に違いはありません。あなたが提供できる助けをいただければ幸いです！

編集:これは、パスの生成に問題があるように思われることをおそらく追加する必要があります。すべてのパスを削除すると、これがうまく機能します。問題は、パスが正しく、このコードが開発中に正常に実行されることです。本番環境でパスが生成されない理由がわかりません。

ここでの問題は、リクエストのコンテキスト外で rake タスクを実行しているため、操作するホストがないことです。ソースから:

例外は次の場所で発生します: https://github.com/mbleigh/subdomain-fu/blob/v0.5.4/lib/subdomain-fu.rb#L65

nil ホストを分割しようとしていることがわかります。https://github.com/mbleigh/subdomain-fu/blob/v0.5.4/lib/subdomain_fu/url_rewriter.rb#L6へのスタック トレースをたどる

渡されたホストが

options[:host] || default_url_options[:host]

通常、default_url_options[:host]リクエストの Host ヘッダーから入力されますが、これはリクエストの外部にあるため、操作するホスト ヘッダーはありません。あなたがする必要があるのは次のいずれかです：

  1. default_url_optionsアプリケーションコントローラーでオーバーライドしてデフォルトのホストを設定します: http://guides.rubyonrails.org/action_controller_overview.html#default-url-options
  2. または、呼び出し元のルート オプションに :host を渡しますmotorsport_event_organization_path。

最初のオプションがおそらく最も簡単です。
