此代码适用于其他人的本地计算机 - 我们尚未在生产中运行它。但我的工作没有用。同事表示我需要创建一个数据库。在使用mysql之前,我使用的是sqlite,它不需要这个。
当我运行python manage.py runserver时,这就是我得到的:
XX-MacBook-Pro:xx xx$ python manage.py runserver

django.db.utils.OperationalError: (1049, "Unknown database 'testdb'")
我的设置文件包含:
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
...
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'testdb',
'USER': ‘xx’,
'PASSWORD': ‘xx’,
'HOST': 'localhost'
}
}
我测试了用户,密码并知道它们有效。我的MySQL功能齐全。
如果我删除了DATABASES'NAME',我会得到:
django.db.utils.OperationalError: (1046, 'No database selected')
答案 0 :(得分:1)
据推测,您已经通过进入mysql shell测试了用户名和密码。所以你可以再做同样的事情,从那里做CREATE DATABASE testdb
。
