没有返回正确

我的Django应用程序的Django FileField或路径包括编写许多数据文件到服务器，我的用户模型类的一部分，我的本地服务器，我得到保存为dummy_1文件上运行时，看起来像这样没有返回正确

class UserData(models.Model): 
    email = models.EmailField() 
    course_id = models.IntegerField() 
    data = models.FileField(upload_to=make_user_data_path) 

def make_user_data_path(instance, filename): 
    username, domain = instance.email.split('@') 
    name = username + '.bin' 
    return os.path.normpath(os.path.join('gameservice', 'userdata', domain, name))

。 bin，dummy_2.bin，dummy_3.bin ...等在app/uploads/gameservice/userdata/sgi-singapore /，它工作正常

但是，当我部署到heroku它似乎无法检索数据..我得到这样的错误

media root =/app/uploads/

文件似乎不会被保存在服务器上，heroku运行猫/app/uploads/gameservice/userdata/sgi-singapore.com/krislee.bin返回没有这样的文件或目录 – henghonglee 2012-03-13 09:53:00
