tornadowebに沿ってDjangoを使用しているこの関数を検討してください
def MeetingRecord(userid,mtngid,mesg):
obj = Usage()
obj.name = userid
obj.meeting_id = mtngid
obj.action = mesg
# obj.participantid = participantid
obj.save()
こちらがモデルです
class Usage(models.Model):
user = models.ForeignKey('User',related_name = 'usage_user',null = True)
meeting = models.ForeignKey('Meeting',related_name = 'meeting_usages',null = True)
participant= models.ForeignKey('Participant',related_name = 'meeting_participant_id',null = True)
date = models.DateTimeField(auto_now = True)
action = models.CharField(max_length = 500)
miscellaneous = models.CharField(max_length = 500)
私はこのメソッドを次のような竜巻クラスから呼び出しています
MeetingRecord(check_user_exist,mtng,mesg)
しかし、私は次のトラックバックを得ています

useridがUserクラスのインスタンスであり、mtngidが会議クラスのインスタンスであることを確認したいと思います。
このエラーが発生する理由を教えてください。
