这是我的model.py

from django.db import models

class Flower(models.Model):
    name = models.CharField(max_length = 30)
    price = models.IntegerField()
    image = models.ImageField(upload_to = 'static/media')
    def __unicode__(self):
        return self.name

urls.py

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

    urlpatterns = patterns('',
        # Examples:
        url(r'^$', 'site1.views.home', name='home'),
        # url(r'^mysite1/', include('mysite1.foo.urls')),

        # Uncomment the admin/doc line below to enable admin documentation:
        # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

        # Uncomment the next line to enable the admin:
        url(r'^admin/', include(admin.site.urls)),
    )

admin.py

from django.contrib import admin
from site1.models import Flower

admin.site.register(Flower)

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。

【问题讨论】：

您的模型看起来不错。您能否提供更多详细信息 - 例如完整的回溯，您如何尝试访问它？为什么url中有site1？
仍然无法提供上述信息。能否给出admin.py里面的目录结构和代码？
是的，正如 Sholomitcky 所说 - 我猜你是在执行 syncdb 之后添加了 ImageField。清除 db 并再次执行 syncdb。你应该没事。

【解决方案1】：

根据 *Exception Value: no such column: site1_flower.image* 我想，你在 syncdb 之后添加了图像字段。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
