我正在尝试构建一个 API，学生将在其中提出问题，而老师将回答该问题。对于提问和回答，我使用的是博文方式。现在，我的问题是我正在尝试从序列化程序发送邮件。但是当我想检测帖子作者时，我无法做到这一点。我可以发送选定的用户，但不能从模型发送。如果有人可以帮助我，那将非常有帮助。非常感谢。
这些是 add_question 模型并回答问题模型 ---
class add_question(models.Model):
title = models.CharField(max_length=250, blank=False)
description = models.TextField(blank=True, null=True)
is_answered = models.BooleanField(default=False)

created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
created_by = models.ForeignKey(User, blank=False, on_delete=models.CASCADE)
STATUS = (
('Published', 'Published'),
('Suspended', 'Suspended'),
('Unpublished', 'Unpublished'),

RESOLUTION = (
('Resolved', 'Resolved'),
('Unresolved', 'Unresolved'),

return self.title
class add_questionFile(models.Model):

file = models.FileField('files', upload_to=path_and_rename, max_length=500, null=True, blank=True)
这些是序列化程序
