我正在尝试迁移到django中的postgresql数据库,以复制将要迁移到的生产环境。
我想我已经设置了postgresql数据库OK - 并将django中的设置文件更改为以下内容:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'teamexchange',
'USER': 'oliver',
'PASSWORD': '',
'HOST': '127.0.0.1',
'PORT': '',
}
}
但是当我尝试使用manage.py来迁移表和重新上载数据时
e.g:
python3 manage.py migrate --run-syncdb
我收到以下错误:
Traceback (most recent call last):
File "/Users/olivermonaghan-coombs/.virtualenvs/my_django_environment/lib/python3.6/site-packages/django/db/backends/utils.py", line 85, in _execute
return self.cursor.execute(sql, params)
psycopg2.ProgrammingError: relation "teamapp_team" does not exist
LINE 1: SELECT "teamapp_team"."team_code" FROM "teamapp_team"
^
The above exception was the direct cause of the following exception:

我试过了:
但我仍然得到同样的错误。
任何帮助非常感谢
