To do this is reasonably straightforward.
First create your form, as described in the docs you referred to already.
Then, in your controller you need to instantiate an object that contains
the data you want to pre-fill with. Here's a simple example (showing how
you might get an existing user's record from the database):
edit_user_form = UserForm("edit_user_form", action="updateuser")
@expose("myapp.templates.user_form")
def edituser(self, **kw):
"""Page showing a form to edit an existing user"""
# get user record from database
user_id = kw['user_id']
my_user = DBSession.query(User).filter_by(id=user_id).one()
# set up a form in the template's context
pylons.c.form = edit_user_form
# return all the data you want in the template
return dict(my_user=my_user)
Then, in your template (templates/user_form.html) you need to do something
like this:
${tmpl_context.form(my_user)}
bo.
