How can i map two table ids using django views

from django.http import HttpResponse
from django.shortcuts import render
from .models import Author, Book
from .forms import AuthorForm, BookForm


def home(request):
    if request.method == 'POST':
        form = BookForm(request.POST)
        aform = AuthorForm(request.POST)
        if form.is_valid():
            book = form.save()
            aform.save(commit=False)
            aform.book = book
            aform.save()
            return HttpResponse('sucess')
    form = BookForm()
    aform = AuthorForm()
    return render(request, 'home.html', {
        'form': form,
        'aform': aform
    })

<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    {{ aform.as_p }}
    <input type="submit">
</form>
