Question

我的django项目早先使用过sqlite，但现在我们已将其更改为使用Postgresql。以下是新设置：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'vader',
        'USER': 'root',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

我创建了一个db vader和root用户作为其所有者。现在，当我尝试使用以下命令应用迁移时：

python manage.py migrate

我收到以下错误：

django.db.utils.OperationalError: fe_sendauth: no password supplied

这是说没有提供密码，但我不知道在哪里传递密码。我有什么想法可以解决这个问题吗？

Answer 1

您需要将数据库用户密码添加到settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'vader',
        'USER': 'root',

        # Add password here 
        'PASSWORD': '',


        'HOST': 'localhost',
        'PORT': '5432',
    }
}

Answer 2

您需要像这样删除PASSWORD，HOST和PORT：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'vader',
        'USER': 'root'
    }
}

然后再次进行迁移。

无法将django迁移应用于postgres数据库
