我是编程和学习Web开发的新手。我安装了:
-Django 1.9
-postgresql 9.5
-psycopg2(使用whl文件)db api用于Windows 7操作系统上的postgresql。
不是虚拟环境。
我已在我的 settings.py 文件中为我的项目设置了数据库连接,如下所示。
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'Test',
'User': 'postgres',
'PASSWORD': 'admin',
'HOST': 'localhost',
'PORT': '5432',
}
}
但是当我运行迁移时,我遇到了以下问题。我想将postgres连接到我的django
请参阅以下错误:

我已经用python脚本检查了psycopg2是否能够在postgresql中连接数据库,但是当我从django项目运行迁移时,它无法正常运行并出现上述错误。
答案 0 :(得分:1)
您的数据库配置:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'Test',
'User': 'postgres',
'PASSWORD': 'admin',
'HOST': 'localhost',
'PORT': '5432',
}
}
应该是:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'Test',
'USER': 'postgres',
'PASSWORD': 'admin',
'HOST': 'localhost',
'PORT': '5432',
}
}
请注意,User
应为USER
