我通过 Django 将 MySQL 数据库连接到项目。在settings.py
文件中,我规定了以下内容:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'mydb',
'USER': 'root',
'PASSWORD': '1',
}
}
接下来,为了测试配置,我执行以下命令:
>>> from django.db import connection
>>> cursor = connection.cursor()
控制台给了我以下信息:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/django/db/__init__.py", line 11, in <module>
if settings.DATABASES and DEFAULT_DB_ALIAS not in settings.DATABASES:
File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 53, in __getattr__
self._setup(name)
File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 46, in _setup
% (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
请帮帮我。我最近开始学习 Django。
