內容類型錯誤

Question

我正在使用Django 1.8，並且我有一個應用程序在此上完美運行。但現在我遷移整個數據庫，每當我試圖在管理訪問記錄我得到這個錯誤：

我曾與1.7開始的項目，但在我到1.8，一個應用程序沒有被運行問題。不過，我之前沒有遷移整個項目。我可以從遷移歷史中看到，此遷移對auth應用進行了遷移。但即使我在此之前遷移，我也會遇到同樣的錯誤。

在切換到1.8之前，我有這個或類似的錯誤，但它不是名稱字段的問題。而且我無法刪除數據庫中的django_content_types表，因爲auth已鏈接到此表。我能以某種方式解決此問題嗎？

因此，確保開發服務器和生產服務器在Django 1.8上運行後，一切運行良好。我在啓動腳本的環境路徑中遇到了一些困惑。
