私はRubyでカスタム作成された小さなCMSに取り組んでおり、WebサイトはMongrelを使用して実行されています。残念ながら、私はRubyにまったく精通していません。ウェブサイトの一部が最近機能を停止しました（更新などに関連していないため、原因はわかりません）

Railsログの「production.log」を確認すると、次のように表示されます。

app / views / static /frontpage.rhtmlの25行目のActionView::TemplateError（nil：NilClassの未定義のメソッド `name'）：22：<％Tabloid.find（：all、：limit => 4、：order = >'date DESC'）。each do | tabloid |％> 23：24：<％= link_to tabloid.title、：controller =>'tabloid'、：action =>'show'、：id => tabloid.id％ > 25：

<％= tabloid.date.strftime（ "％d of％B、％Y"）％>作成者：<％= Profile.find（：first、：conditions => ["user_id =？"、tabloid.user_id]） .name％> <％= Profile.find（：first、：conditions => ["user_id =？"、tabloid.user_id]）。surname％>

26：

<％= RedCloth.new（truncate（tabloid.texto、250））。to_html％>

27：<％（tabloid.texto.size> 250％> 28の場合）：

<％= link_to "続きを読む>"、：controller =>'tabloid'、：action =>'show'、：id => tabloid.id％>

など。Mongrelログは実際にはしばらく更新されていません。問題が何であるか、またはどこで掘り続けるべきかについての指針はありますか？
