Question

我目前正在为应用程序使用DRF。我设法将.jpg文件发送到服务器，并使用request.FILES进行检索。但是，当我尝试将对象的照片设置为图像时，会出现unicode错误。请帮助。

示例用法：-我已经从request.FILES中检索了照片，并打印了file.jpg

@staticmethod
    def create_user_type(user_type, data, photo):
        if user_type == "Driver":
            driver = Driver.objects.create(**data)
            driver.photo = photo
            driver.save()
            return driver

models.py

class Person(SoftDeletionModel):
    name = CharField(max_length=64)
    email = CharField(blank=True, null=True, max_length=64)
    contact_no = PositiveIntegerField()
    address = CharField(max_length=256)
    birth_date = DateField()
    sex = CharField(max_length=1, choices=SEX)
    photo = FileField(default='client/src/images/users.png', null=True)


class Driver(Person):
    user = OneToOneField(User, on_delete=models.CASCADE, null=True)
    application_date = DateField()
