python - 连接mysql到Django-python

Question

当我尝试将 MySQL 连接到 python Django 框架以访问数据库并运行命令 python manage.py syncdb 时，出现以下错误。我已经创建了数据库名称 mysite 并更改为这样的设置:

DATABASES = {
    'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'mysite',
    'USER':'root',
    'PASSWORD':'sobita1',
    'HOST':'',
    'PORT':'',
    }
}

回溯:

python manage.py syncdb

Answer 1

我有一个类似的错误:

super(Connection, self).init(*args, **kwargs2) django.db.utils.OperationalError: (1045, "Access denied for user 'root'@'localhost' (using password: YES)")

解决方法:

1) 我删除了我提供的密码，但我再次遇到这样的错误:

File "C:\Users\Rooman\AppData\Local\Programs\Python\Python37\lib\site-packages\django\db\backends\mysql\operations.py", line 146, in last_executed_query query = query.encode(errors='replace') AttributeError: 'bytes' object has no attribute 'encode'

2) 在operations.py中使用decode代替encode

    query = query.decode(errors='replace')

3) 最后运行命令:

    python manage.py makemigrations

    python manage.py migrate

    python manage.py runserver
