[Fixed]-Django form with fields from two different models


The other answers on this page involve tossing away the benefits of model forms and possibly needing to duplicate some of the functionality you get for free.

The real key is to remember that one html form != one django form. You can have multiple forms wrapped in a single html form tag.

So you can just create two model forms and render them both in your template. Django will handle working out which POST parameters belong to each unless some field names clash – in which case give each form a unique prefix when you instantiate it.


class CompanyForm(forms.ModelForm):
    class Meta:
        fields = [...]
        model = Company

class AccountForm(forms.ModelForm):
    class Meta:
        fields = [...]
        model = Account


if request.method == 'POST':

    company_form = CompanyForm(request.POST)
    account_form = AccountForm(request.POST)

    if company_form.is_valid() and account_form.is_valid():

        return HttpResponseRedirect('/success')        

        context = {
            'company_form': company_form,
            'account_form': account_form,

    context = {
        'company_form': CompanyForm(),
        'account_form': AccountForm(),

return TemplateResponse(request, 'your_template.html', context)


<form action="." method="POST">
    {% csrf_token %}
    {{ company_form.as_p }}
    {{ account_form.as_p }}
    <button type="submit">


In your forms.py

from django import forms

class YourForm(forms.Form):
    title = forms.CharField()
    first_name = forms.CharField()
    last_name = ...

In your views.py

from forms import YourForm
from django import views
from models import Company, Account

class YourFormView(views.FormView)
    template_name = 'some_template.html'
    form_class = YourForm
    success_url = '/thanks/'

    def form_valid(self, form):
        title = form.cleaned_data['title']
        # do your processing here using Company and Account
        # i.e. company = Company.objects.create(title=title, ...)
        #      account = Account.objects.get_or_create(
        #      user=..., company=company ...)
        #      ... more processing
        # Call company.save() and account.save() after adding
        # your processed details to the relevant instances
        #  and return a HttpResponseRedirect(self.success_url)

    def is_valid(self):
        # don't forget to validate your fields if need be here

As usual the docs are pretty helpful.
