我一直試圖讓這個主題開放給予edX工作（基於Django的），我得到這個錯誤在管理日誌 -Django的錯誤 - AttributeError的：「CourseOverview」對象有沒有屬性「start_datetime_text」
AttributeError: 'CourseOverview' object has no attribute 'start_datetime_text'
整個錯誤是這樣的 -

問題（一說是給錯誤 - course.html.py）的文件是在這裏 https://pastebin.com/0S79hhDa
您是否需要運行數據庫遷移？這些往往導致類似這樣的錯誤。 –
將您的文件名改爲course.py – Exprator
@Exprator你確定嗎？我認爲目錄中的所有文件都被命名爲[*] .html.py，其他文件工作正常 –
