我有一个在我的电脑上缓慢构建起来的项目,它正常运行。现在我想将它放到服务器上,但我遇到了以下错误:
django.db.utils.ProgrammingError: relation "django_content_type" does not exist
我无法找出问题所在,Stackoverflow上的帖子建议删除迁移并重新创建,但我已经尝试过却仍然存在相同的问题。如果您能指导我应该查找什么,我将不胜感激。
下面是错误追溯:

文件中(看起来您有一个),将url_patterns = [...]
放在try-Except
结构内,并在 Exception 部分设置urlpatterns=[]
。您的错误可能是因为代码尝试处理尚未设置的数据库而导致的。 - Alain
