我在 Mac OS X 10.8.2 和 Python 2.7.2 上使用 django 版本 1.5c1

我在model.py文件中定义了以下模型：

class MyFile(models.Model):
    filename = models.FileField(upload_to = '%Y/%m/%d')

并通过在文件中添加以下行将其注册到自动管理界面admin.py：

class FileAdmin(admin.ModelAdmin):
    list_display = ('filename',)
    fields = ('filename',)

admin.site.register(MyFile, FileAdmin)

使用管理网络界面向数据库添加新File对象时，我总是收到以下错误消息：

Environment:

Exception Type: TypeError at /admin/mytest/myfile/add/
Exception Value: 'FieldFile' object is not subscriptable

该文件保存在正确的位置，但没有任何内容添加到数据库中。有关如何解释此'FieldFile' object is not subscriptable错误消息的任何线索？

亲切的问候，汉斯
