python 2.7 - Flexible number of form fields in Django forms -

i create form contains several fields this

class mainform(forms.form):     name = forms.charfield(label='name')     comment = forms.charfield(label='comment')

right have 1 field "comment". want have option user can add more comment fields form through website.

so need to:

1) define form more flexible such there can n comment fields. (default n=1)

2) define method add new comment fields.

3) define utility functions, cleaning form fields, flexible can handle dynamic number of comment fields.

i ideas of how set in clean way.

formsets solution this:

it handle 1 , 3 cleanly. have had write javascript in past inject fields in form when clicking add. after submit django takes care of rest.
