[PYTHON] [Django] Give Form a dynamic initial value from Model

environment Python 3.5.0 Django 1.9.2

`forms.py`


class CakeForm(forms.Form):
    cake_num = IntegerField(label='Number of cakes', min_value=0)

    class Meta:
        model = Cake

`views.py`


def edit(request, store_id):
	#If you can get cake, set the initial value
	try:
		cake = Cake.objects.get(store=store_id)
		cake_form = CakeForm(initial = {
		    'cake_num': cake.cakenum    #initial value
		})
	#If cake cannot be obtained, the initial value is not set.
	except:
		cake_form = CakeForm()

In such cases, you would normally use ModelForm. .. ..
