Using forms with models

How would I display form based on models when I am using composition with them? As an example

class House(models.Model):
    number_of_roommates = models.IntegerField(default=0)

class Posting(models.Model):
    title = models.CharField(max_length=150)
    description = models.CharField(max_length=500)
    house = models.OneToOneField(House)

I am stumped on what the view should be like. Right now I have two form classes for each of the Models.

def form_view(request):

    if request.method == "POST":
        Post = Posting(request.POST) ##Not really sure what to do here
        house = House(request.POST)
        if form.is_valid():
            post = form.save(commit=False)
            post.save()
            return redirect('co_op.views.list_view')
    else:
        descriptionForm = PostDescription()
        houseForm = HouseDescription()
    return render(request, 'co_op/form_view.html', { 
                                                    'descForm' : descriptionForm, 'houseForm' : houseForm,})
