我无法迁移我的代码。我在MySql中创建了一个数据库和一个表,但由于某种原因我不得不卸载MySql,当我再次安装它时,我将用户名更改为root。现在它一直在说
(1045,“访问被拒绝用户'djanu'@'localhost'(使用密码:否)”)
当我尝试迁移时。我在第一次安装时将用户命名为djanu,并尝试向root用户授予权限,但同样的消息不断弹出。
这是我在settings.py中的代码
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'applics',
'USER': 'root',
'Password': '531010',
'HOST': '',
'PORT': '',
}
}
当我使用python manage.py migrate或者甚至是runserver 时,和我的代码
(myproject) C:\Users\home\myproject\collapp>python manage.py migrate

答案 0 :(得分:0)
这种情况多次发生在我身上。可能的解决方案是从迁移文件夹中删除所有迁移,然后运行manage.py migrate。
