我正试图在我的django项目的mssql数据库上执行sudo ./manage.py dumpdata
,但一直得到:
Traceback (most recent call last):

pyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')
我完成了https://code.google.com/p/django-pyodbc/wiki/FreeTDS中提到的配置,我得到了所有测试工作(FreeTDS和ODBC)。
这是我当前的settings.py
数据库配置:
DATABASES = {
...
'vcoe':
{
'ENGINE' : 'sql_server.pyodbc',
'NAME' : 'VOIP',
'USER' : '******',
'PASSWORD' : '******',
'OPTIONS' : {
'driver': 'FreeTDS',
'dsn': 'VCOE',
}
}
}
DATABASE_ENGINE = 'sql_server.pyodbc'
DATABASE_NAME = 'VOIP'
DATABASE_USER = '******'
DATABASE_PASSWORD = '******'
DATABASE_OPTIONS = {
'driver': 'FreeTDS',
'dsn': 'VCOE', # ODBC DSN name defined in your odbc.ini
}
当我尝试运行./manage.py test
时,我得到:

我尝试删除DATABASES = {...}
部分,只留下DATABASE_XXX
,但获取:

答案 0 :(得分:0)
您正在使用不再维护的非常非常旧的django-pyodbc版本。这是最后一次更新于2011年。我在使用dumpdata
和dbshell
时遇到了旧版本的问题。我建议使用这个版本,积极维护,这在几个Django项目中对我来说非常有效:
https://github.com/michiya/django-pyodbc-azure
注意,要安装它,你必须这样做,因为你没有使用Django 1.8:
pip install django-pyodbc-azure<1.8
偏离主题:如果你刚刚开始一个项目,我建议你使用Django 1.8.x.虽然Django 1.7.x仍然受支持,但Django 1.8.x是一个长期版本,这意味着它将至少支持三年。祝你好运!
