Question

我的django应用程序涉及将许多数据文件写入服务器，我的用户模型类的一部分看起来像这样

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))

在我的本地服务器上运行时，我在app / uploads / gameservice / userdata / sgi-singapore /中将文件保存为dummy_1.bin，dummy_2.bin，dummy_3.bin ...等，它工作正常

然而，当我部署到heroku时，它似乎无法检索数据..我得到这样的错误

media root = / app / uploads /

当我输出保存时，似乎是正确的，

我该如何解决这个问题？

Answer 1

我上传的文件竟然是json文件，我最终将它们切换到文本字段并将这些文件上传到数据库而不是上传的目录文件。这完全解决了我的问题。如果有人有兴趣
