python - Django:TypeError: 'x' 是此函数的无效关键字参数

Question

下面的 View 有效，它利用“update_or_create”功能，当某些东西存在并因此更新记录时非常出色。但是，如果它不存在并且必须使用创建选项来创建新记录，我会收到以下错误:

TypeError at /selectteams/1025/3/

'soccerseasonid_id' is an invalid keyword argument for this function

查看下方:

if request.method == 'POST':

    form = SelectTwoTeams(request.POST,user=request.user)

    if form.is_valid():

    teamSelection1, created = UserSelection.objects.update_or_create(user_id=currentUserID,
                                     fixturematchday=fixturematchday,
                                     soccerseason_id=soccerseason,
                                     teamselection1or2=1,
                                     defaults={"campaignno":11,
                                           "teamselection1or2":1,
                                           "teamselectionid_id":request.POST['team1'],
                                           "user_id":currentUserID,
                                           "fixturematchday":fixturematchday,
                                           "soccerseasonid_id":soccerseason})

    teamSelection2, created = UserSelection.objects.update_or_create(user_id=currentUserID,
                                     fixturematchday=fixturematchday,
                                     soccerseason_id=soccerseason,
                                     teamselection1or2=2,
                                     defaults={"campaignno":11,
                                           "teamselection1or2":2,
                                           "teamselectionid_id":request.POST['team2'],
                                           "user_id":currentUserID,
                                           "fixturematchday":fixturematchday,
                                           "soccerseasonid_id":soccerseason})

下面的模型:

class StraightredSeason(models.Model):
    seasonid = models.IntegerField(primary_key = True)
    seasonyear = models.CharField(max_length = 4)
    seasonname = models.CharField(max_length = 36)

    def __unicode__(self):
        return self.seasonid

    class Meta:
        managed = True
        db_table = 'straightred_season'

class UserSelection(models.Model):
    userselectionid = models.AutoField(primary_key=True)
    campaignno = models.CharField(max_length=36,unique=False)
    user = models.ForeignKey(User, related_name='selectionUser')
    teamselection1or2 = models.PositiveSmallIntegerField()
    teamselectionid = models.ForeignKey('straightred.StraightredTeam', db_column='teamselectionid', related_name='teamID')
    fixturematchday = models.IntegerField(null=True)
    soccerseason = models.ForeignKey('straightred.StraightredSeason', db_column='soccerseasonid', related_name='fixture_seasonUserSelection')


    class Meta:
        managed = True
        db_table = 'straightred_userselection'

如有任何帮助，我们将不胜感激，非常感谢，Alan。

Answer 1

看起来它使用的是您指定的“soccerseasonid_id”而不是“soccerseason_id”的默认值。 “soccerseason_id”应该有效。
