Adding two objects with one django form

Question

Just to mention, English is not my native language.
So my question is, I have a form in Python/Django, that adds a simple object with name and function, example:
Function: programmer
Name: Carlos
What I want to do is to make things simple for the user when he adds several users with the same function, so I thought, when the user do something like this...
Function: programmer
Name: Dean,Seth,Roman,Ross,Joey,Chandler
...my form would add 6 objects, but the problem is that when I do this, python/django always tries to use the same ID/PK(example: tries to add all 6 members with id/pk=1).
I've done a little manuever(in Brasil we call gambiarra), so my code does this(after splitting objects):
form2.name = nombre
form2.pk = primary+1
form2.save()
primary=form2.pk
This basically consists in using this var called primary to change the value of PK and saving to Postgres. It worked, now Dean is pk/id 1....Chandler is pk/id 6, and all in one form.
But, I'm not that lucky, so when I go to add another name, like George, the system tries to use pk=2.
Does anyone knows to resolve this thing without this manuever or how to improve this manuever to solve completely?

My code (just to remind, I'm a python beginner):
objnet = form.save(commit=False)
if ',' in objnet.netaddr:
listaips = objnet.netaddr.split(',')
codeon = 1
nomecomum=objnet.nome
for ip in listaips:
objnet.netaddr = ip
objnet.nome = nomecomum + "_" + str(codeon)
objnet.save()
codeon+=1
else:
objnet.save()

Explanation:
I have a form with an IP field(netaddr) and a char field(nome)....if contains a ',' in IP field, it will add more than one object, example:
nome = carlos
netaddr = 2.2.2.2,3.3.3.3
it should add carlos_1 in my DB with IP 2.2.2.2, and carlos_2 with IP 3.3.3.3. And the code really does that, but, he adds carlos_1 and then, he tries to add carlos_2, he does with the same PK, so instead of adding another element, he overwrites carlos_1, so in my DB now there's only carlos_2.

Thank you

You have such problem because objnet always link to one object (since form.save() returns object)

Quick fix:

if ',' in objnet.netaddr:
    listaips = objnet.netaddr.split(',')
    codeon = 1

    for ip in listaips:
        objnet = form.save(commit=False)
        objnet.netaddr = ip
        objnet.nome = objnet.nome + "_" + str(codeon)
        objnet.save()

        codeon+=1
else:
    form.save()
