You will need a dynamically generated form as you don't know ahead of
time how many Products you might have.
Here's something to get you started (hastily put together and
completely untested):
import django.newforms as forms
import django.newforms import widgets
from products import models
class MyForm(forms.Form):
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__(*args, **kwargs)
i = 0
for p in models.Product.objects.select_related().all():
self.fields['product_%s' % i] = forms.CharField(
widget=widgets.HiddenInput(),
initial=p.pk)
self.fields['checkbox_%s' % i] =
forms.CheckboxField(initial=False)
self.fields['name_%s' % i] = forms.CharField(initial=p.name)
self.fields['price_%s' % i] =
forms.DecimalField(initial=p.price)
options = p.option_set.all()[:1] # assumes at most one Option
per product
if options:
self.fields['checkbox_%s' % i].initial = True
self.fields['name_%s' % i].initial = options[0].name
self.fields['price_%s' % i].initial = options[0].price
i += 1
Note that the above assumes your model class names to be Product and
Option (singular). It's good practice to not use plural names. Also
the above assumes at most one Option per product.
