将 Django 应用程序发布到 Azure 时出现服务器错误

Question

我正在尝试使用 MSSQL 服务器将我的 Django 应用程序发布到 Azure。我正在使用 django-azure-pyodbc 和 pyodbc 进行连接，虽然它在本地工作，但每当我使用 mssql 发布时，我都会收到内部服务器错误，尽管发布成功。如果我使用预打包的 sqllite3 服务器发布，它就可以工作。我正在使用 Python 3.4、Django 1.8.4、pyodbc 3.0.10 和 django-pyodbc-azure 1.8.3.0 的虚拟环境。我的settings.py文件如下

DATABASES = {
   'default': {
        'ENGINE': 'sql_server.pyodbc',
        'NAME': 'db_name',
        'USER': 'u_name',
        'PASSWORD': 'p_word',
        'HOST': 'host.database.windows.net',
        'PORT': '',
    }
}

我已将 Web 应用程序的传出 IP 地址添加到服务器，希望这是问题所在，但事实并非如此。检查诊断日志后，我发现了比 500 错误更详细的解释，但我不确定我是否理解它。

Answer 1

我真的不知道 Azure 是如何工作的，但我在混合使用 32 位和 64 位 driver/python 组合时遇到了这个错误。尝试使用 x64 位版本的 python 和驱动程序。

Answer 2

我无法重现您的问题，但我对您的软件包和版本进行了测试。我使用 Visual Studio 将 Django 应用程序发布到 Azure Web Apps，它运行良好。以下是我的步骤供您参考： 1，创建一个空的 Web App 并从本地 Git repo

设置部署

2、在Visual Studio中创建一个Django应用程序，添加python3.4的虚拟环境，然后安装python包，这里是requirements.txt中的内容： Django==1.8.4 pyodbc==3.0.10 django-pyodbc-azure==1.8.3.0

3、Azure上修改数据库设置为MSSQL，本地按F5测试

4、右击Django应用项目名，点击publish部署

部署完成后，它会自动在默认浏览器中浏览您的应用程序。

Answer 3

问题是我的出版同事在他的环境中使用 64 位版本的 python。很简单，但我很感激你的帮助。
