问题描述
我正在尝试使用弹性beantalk部署网站并将其连接到Postgres数据库。尝试在Django中进行迁移时，出现错误。
我已经能够成功建立本地Postgres数据库。 我已经尝试了一段时间没有运气了。
这是错误日志

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

这是我的项目.settings.py文件的数据库部分：
from .base import *
DEBUG = config('DEBUG',cast=bool)
ALLOWED_HOSTS = ['localhost','127.0.0.1','http://cliquefit-dev.ap-southeast-2.elasticbeanstalk.com','*******']
AUTH_PASSWORD_VALIDATORS = [
{'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator'},{'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator'},{'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator'},{'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator'}
]
DATABASES = {

}
}
这是我的Django配置文件
