from django import forms

from .models import Customer, Vms, Vmspecs

class SignUpForm(forms.ModelForm):

        class Meta:

                model = (Customer, Vms, Vmspecs)

so I changed it a bit after doing some more research however formb, and formc don't display, if I change the 'formb' to 'form' it will overwrite the first one and only display the second one.

This is how i read the forignekey associate between multiple forms to be. 

from django.shortcuts import render

from django.http import HttpResponse

from vmware.models import Customer

from django.shortcuts import render_to_response

from vmware.models import Vms

from .forms import SignUpForm

from .forms import VmForm

from .forms import VmSpecForm

from vmware.models import Vmspecs

from django.views.decorators.csrf import csrf_protect

from django.template import Template, RequestContext

#@csrf_protect

def index(request):

        form = SignUpForm(request.POST or None)

        formb = VmForm(request.POST or None)

        formc = VmSpecForm(request.POST or None)

        if form.is_valid():

                save_it = form.save(commit=False)

                save_it.save()

                save_itb = formb.save(commit=False)

                save_itc = formc.save(commit=False)

                save_itb.CUSTOMERID = save_it

                save_itb.save()

                save_itc.VMID = save_itb

                save_itc.CUSTOMERID = save_it

                save_itc.save()

        customers = Customer.objects.all()

        ctx = { 'customers':customers, 'form':form, 'formb':formb, 'formc':formc}

        return render_to_response('index.html', ctx, context_instance=RequestContext(request)) 

<form action='' method='POST'> {% csrf_token %}

     {{ form.as_p }}

     {{ formb.as_P }}

     {{ formc.as_P }}

     <p><input type="submit" value="Add"></p>

</form>

Why not just do this? (Sorry for the crappy indentation.. tab doesn't work on here for some reason)

models.py:

 

class SignUpForm(forms.ModelForm):

        class Meta:

                model = Customer

 

class VmForm(forms.ModelForm):

        class Meta:

                model = Vms

class VmSpecForm(forms.ModelForm):

        class Meta:

                model = Vmspecs 

views.py

def index(request):

       if request.POST:

        form = SignUpForm1(request.POST or None)

        formb = VmForm(request.POST or None)

        formc = VmSpecForm(request.POST or None)

        if form.is_valid() and formb.is_valid() and formc.is_valid()

                form.save()

                formb.save()

                formc.save()

else

load template and forms etc..

Does that work if they all have forignekey associations with each other?

[G Z]

I tried it it doesn't work because they keys don't associate when you click save.
