    urlpatterns = patterns('',

        # url(r'^mysite1/', include('mysite1.foo.urls')),

        # Uncomment the admin/doc line below to enable admin documentation:

Exception Type: DatabaseError at /admin/site1/flower/
Exception Value: no such column: site1_flower.image

我想从管理面板将图像上传到我的站点数据库，这样我就可以在任何我想要的地方查看这些图像。但我遇到了一个错误：

DatabaseError at /admin/site1/flower/
no such column: site1_flower.image
Request Method: GET
Request URL:    http://127.0.0.1:8000/admin/site1/flower/
Django Version: 1.4.3
Exception Type: DatabaseError
Exception Value:    
no such column: site1_flower.image

我该如何克服这个问题。

根据 *Exception Value: no such column: site1_flower.image* 我想，你在 syncdb 之后添加了 image 字段。因此，图像字段在 db 中不存在。最简单的方法是完全删除 Flower 模型并再次运行 syncdb。或者您可以在您的数据库中手动创建此字段。但最好的方法是使用django south
