django - MultiValueDictKeyError django 表单集

Question

我正在尝试从表单集中发布数据，但出现了 MultiValueDictKeyError

查看

            from django.forms.models import modelformset_factory
            BetFormset = modelformset_factory(Bet, form=Bets, extra=0, max_num=1)
            if request.method == 'POST':
                data = BetFormset(request.POST, prefix='bet')

表格

class Bets(ModelForm):
    error_css_class = 'error'
    exclude = ['',]
    class Meta:
        model = Bet
        widgets = {
            'amt': TextInput(attrs={'class':'bet_amt',}),
            'status': HiddenInput(),
            'parlay':CheckboxInput(attrs={'class':'parlay'}),
            'user':HiddenInput(),
            'offer':HiddenInput(),
            'bet_cat':HiddenInput(),
            }

型号

class Bet(models.Model):
    BET_STATUS = (
        (1, 'Open'),
        (2, 'Submitted'),
        (3, 'Paid'),
     )
    BET_CATS = (
        ('STAGE', 'Stage Winner'),
        ('GC', 'General Classification'),
        ('MTN', 'King of the Mountains'),
        ('SPRNT', 'Sprinter'),
        ('YTH', 'Youth'),
     )
    amt = models.FloatField(null=True, blank=True,verbose_name="bet amount mBtC")
    user = models.ForeignKey(User)
    offer = models.ForeignKey("StageRider")
    status=models.IntegerField(max_length=1,choices=BET_STATUS,default=1)
    parlay=models.BooleanField(null=False, blank=False, default=False)
    bet_cat = models.CharField(null=False, max_length=10,blank = False, choices = BET_CATS)
    class Meta:
        unique_together = ("user","status","offer","bet_cat")
        ordering = ['id']

模板

<form action="" method="post" enctype="multipart/form-data" >

Parlay Amt: <input id="parlay_amt" class="bet_amt" type="text" name="parlay_amt"> <br>

{% csrf_token %}

<table class="table table-striped" id="bet_table"><thead><th>Bet</th><th>Odds</th<th>Amount</th<th>Parlay

key

u'bet-0-id'

Answer 1

我不知道这是否是“真正的”解决方案，但如果我将 id 作为隐藏字段添加到表单中，则不再有错误
