Django formsets __init__() got an unexpected keyword argument 'extra' - django

Question

I have created two models w_orders(workorders) and tobjects. I have two templates, one is only for creating a workorder and this works fine and one other template which contains data of both workorders and objects. tobjects is related to the table w_orders and I want to be able to create x number of objects for a workorder. For every workorder an object is created automatically. So far I have created the template and I can't quite figure how to display only the related objects for a certain workorder. For example for workorder no 1 I get the objects that are created for other workorders. As well I cannot add or edit an object related to the workorder. This is my code:
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
