我想在服务器上部署本地工作,但是当我运行python manage.py时,我遇到了psycopg2的问题。迁移时出错 - psycopg2 Django
设置:
DATABASES = {
'default':{
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': '******',
'USER': '*****',
'PASSWORD': '**********',
'HOST': '*******',
'PORT': '5432'
}
}
模型有问题

我在这里错过了什么?
你为什么认为这是导致问题的用户模型?你能否展示你的国家模式?此外,都是在同一个Django应用程序中的模型? –
@MananMehta嘿,因为这个:申请profile.0001_initial。一切工作正常使用sqlite开发服务器本地。这只在使用psycopg2时才会发生。但即时通讯也添加国家模型 –
@AndreMendes你有没有尝试我在答案中提出的建议? –
