Django表单集__init __（）获得了意外的关键字参数'额外'

我创建了两个模型w_orders（workorders）和tobjects。我有两个模板，一个仅用于创建工作单，并且可以正常工作，另一个模板包含工作单和对象的数据。 tobjects与表w_orders相关，我希望能够为一个工作订单创建x个对象。对于每个工作单，将自动创建一个对象。到目前为止，我已经创建了模板，但是我还不太清楚如何仅显示特定工作订单的相关对象。例如，对于第1个工作单，我得到了为其他工作单创建的对象。同样，我无法添加或编辑与工作单相关的对象。这是我的代码：

models.py 

class w_orders(models.Model): 
    Id = models.BigAutoField(primary_key=True)
    datedefwo = models.DateField(default=datetime.now)
    datesched = models.DateField(blank=True, null=True)
    datefinished = models.DateField(blank=True, null=True)
    sign = models.BigIntegerField(blank=True, null=True)
    statusid = models.BigIntegerField(blank=True, null=True, default=1, choices=STATUS_CHOICES)
    typeid = models.BigIntegerField(blank=True, null=True, default=1, choices=TYPE_CHOICES)
    comments = models.CharField(max_length=254, blank=True, null=True)
    navid = models.BigIntegerField(blank=True, null=True)
    navkonsid = models.CharField(max_length=12, blank=True, null=True)
    navname = models.CharField(max_length=254, blank=True, null=True)
    navcustadr = models.CharField(max_length=254, blank=True, null=True)
    navdebt = models.FloatField(blank=True, null=True)
    navpropcode = models.CharField(max_length=254, blank=True, null=True)
    navdepcode = models.CharField(max_length=254, blank=True, null=True)
    navphoneno = models.CharField(max_length=254, blank=True, null=True)
    navreasoncomp = models.CharField(max_length=254, blank=True, null=True)
    nightshift = models.BooleanField(default=False)
    priority = models.BigIntegerField(blank=True, null=True)
    stid = models.BigIntegerField(blank=True, null=True)
    mapurl = models.CharField(max_length=254, blank=True, null=True)

    def __unicode__(self):
        return self.Id




class tobjects(models.Model): 
    oid = models.BigAutoField(primary_key=True)
    wid = models.ForeignKey(w_orders, on_delete=models.CASCADE)
    objtypegisid = models.BigIntegerField(blank=True, null=True, default=1)
    objgisid = models.BigIntegerField(blank=True, null=True, default=1)
    condgenid = models.BigIntegerField(blank=True, null=True, default=1)
    condriskid = models.BigIntegerField(blank=True, null=True, default=1)
    condratsid = models.BigIntegerField(blank=True, null=True, default=1)
    condmhcoverid = models.BigIntegerField(blank=True, null=True, default=1)
    condmhwallid = models.BigIntegerField(blank=True, null=True, default=1)
    condpipehydrsid = models.BigIntegerField(blank=True, null=True, default=1)
    condpipehydreid = models.BigIntegerField(blank=True, null=True, default=1)
    condpipedepvolsid = models.BigIntegerField(blank=True, null=True, default=1)
    condpipedepvoleid = models.BigIntegerField(blank=True, null=True, default=1)
    condpipedepconssid = models.BigIntegerField(blank=True, null=True, default=1)
    condpipedepconseid = models.BigIntegerField(blank=True, null=True, default=1)
    txt = models.CharField(max_length=254, blank=True, null=True)

    def __unicode__(self):
        return self.oid

    @receiver(post_save, sender=w_orders)
    def ensure_order_exists(sender, **kwargs):
        if kwargs.get('created', False):
