Django多站點：ValueError：尚未設置SITE_ID

Question

我最近有一台新計算機，並一直在嘗試設置我的開發環境，現在我需要開發一個Django項目。 不過，我一直運行到這下面的錯誤，每當我嘗試做python manage.py runserver ， makemigrations ， migrate等，我不明白為什么。

Traceback (most recent call last):

ValueError: SITE_ID has not been set.

我檢查了settings.py並發現SITE_ID = 1所以我假設這就是它想要的？ （我對Django也很陌生，對不起！）

在此先感謝您的幫助！

Answer 1

使用django- SITE_ID ，您需要按以下步驟設置SITE_ID

from multisite import SiteID
SITE_ID = SiteID()

Answer 2

從命令行介紹您的環境：

$ export SITE_ID = 1
