我正在使用Postgres和Django。 我将localhost上的服务器更改为Amazon EC2。
然而，当我去'python manage.py makemigrations'或'python manage.py makemigrations myapp'时，我出现了以下错误： Relation [table_name]不存在。
数据库中不会创建关系/表。
Settings.py：
INSTALLED_APPS = [
'myapp',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.sites',
]
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'freguesia',
'USER': 'postgres',
'PASSWORD': 'xxxxx',
'HOST': 'localhost',
'PORT': '',
}
}
错误：

The above exception was the direct cause of the following exception:
