【解决方案1】：

您可以定义upload_to 函数。

def upload_to(instance, filename):
    return 'pic/%s/%s' % (instance.user, filename)

class MedicalRecord(models.Model):
    title = models.CharField(max_length=200)
    date_time = models.DateTimeField()
    user = models.CharField(max_length=200)
    record_file = models.ImageField(upload_to=upload_to)
