我無法加載在Heroku上一個Rails應用程序5由於以下按Heroku的Rails的5無法在Heroku上部署由於::的ActionView ::模板錯誤

ActionView::Template::Error (undefined methodfind_asset' for nil:NilClass)

我相信我找到了導致問題的代碼，主題預編譯資產，以及何時生產heroku有問題併產生錯誤。我找不到任何明確的解決方案，heroku將無法進一步幫助我，並建議Stack並不確定是否有另一種方式在應用程序上獲得預期的效果。我試圖刪除find_assets方法，它在本地工作，但在heroku上導致H10錯誤。

Thanks for reaching out. A 200 status response indicates the request has succeeded, so the log you shared isn't the error. That said, I went ahead and monitored your app while loading the root page and found the following:

我看到了同樣的問題，在軌道上建立紅寶石的Heroku。

如果你使用上面的語句來檢查，如果資產存在，除去小to_s最終因爲nil.to_s =「」 = TRU

有這樣的同樣的問題。有關更多詳細信息，請嘗試。 `undefined method `find_asset' for nil:NilClass`
