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):
  File "./manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)

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：

    raise ImproperlyConfigured('You need to specify NAME in your Django settings file.')
django.core.exceptions.ImproperlyConfigured: You need to specify NAME in your Django settings file.

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

django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

我目前在客户端上使用：

  • Ubuntu 14.04.1 LTS
  • Python 2.7.6
  • Django 1.7.8
  • pyodbc == 3.0.10
  • 的django-pyodbc == 0.2.8

服务器我到达的是：

  • Microsoft Server 2003正在运行：MSSQL 2005

以下是/etc/odbcinst.ini：

[FreeTDS]
    Description = TDS driver (Sybase/MS SQL)
    Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
    Setup = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so
    CPTimeout =
    CPReuse =

双重检查路径，所有文件都存在

这是我的/etc/odbc.ini：

[ODBC Data Sources]
ODBCNAME = Microsoft SQL Server

[VCOE]
Driver = FreeTDS
Description = VOIP Legacy Database
Trace = No
Servername = VOIP
Database = VOIP

[Default]
Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so

这是我的/etc/freetds/freetds.conf：

[VOIP]
host = 142.117.139.***
port = 1433
tds version = 8.0

1 个答案:

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！
