This code demonstrates two simple techniques:
so-called "dynamic" forms, in which the form is created at run time by the model
using a widget (forms.widgets.HiddenInput) for a field of the form. I feel like this could be highlighted more in the documentation. You need to do something similar to get a textarea (forms.CharField(widget=forms.widgets.Textarea()) and it took me too long to figure this out.
There are, no doubt, good reasons not to do what I'm doing here the way I'm doing it. Peanut gallery?

from django import forms hiddenValues = forms.Form() value0 = 17 hiddenValues.fields['value0'] = forms.CharField(initial=value0, widget=forms.widgets.HiddenInput()) # pass the form to your template # render it as you like, e.g. with form.as_p
