模型定義調試在Django

我的模型定義如下，當我運行python manage.py sql應用程序時，它什麼也沒有。我的應用程序名稱是應用程序。當我將模型的內容更改爲教程https://docs.djangoproject.com/en/1.5/intro/tutorial01/時，它提供了正確的sql語句，因此它必須在下面的模型中出現一些錯誤，任何人都可以指出它嗎？模型定義調試在Django

您是否正確導入模型？另外，運行python manage.py syncdb是否會出現錯誤消息？ –

是的，如果我將內容更改爲教程中的模型，它會變得正確。 – young001

這不是我問的。您是否從django.db導入模型中導入了模型，並且在運行syncdb時是否收到錯誤消息？ –

app_label設置爲'backupcenter1'，將其刪除。

app_label = 'backupcenter1'意味着，據Django所知，此型號不屬於您的application應用程序，而是屬於backupcenter1應用程序。因此，爲什麼它不顯示在application應用程序的SQL輸出中。

此外，請注意application是一個應用程序的可怕的名字，你可能想要改變它。

如果我運行python manage.py sql backupcenter1，它會告訴CommandError：無法找到帶有標籤backupcenter1的應用程序。你確定你的INSTALLED_APPS設置是正確的嗎？ – young001

@ young001我認爲'app_label'告訴Django這個模型屬於'backupcenter1'，但它不是一個你有的應用程序，因此是錯誤的。你嘗試刪除'app_label'嗎？ –

@ young001這似乎表明該應用程序未在INSTALLED_APPS中列出您的設置，這很可能是問題 –
