The most basic approach is to extend the setUpWidgets() method:

    def setUpWidgets(self, ignore_request=False):
        super(MyFormClass, self).setUpWidgets(ignore_request=ignore_request)
        self.form_fields['firstname'].setRenderedValue(u'David')

Other ways to initialize the fields are documented in the form.txt
file in the zope.formlib package.  The add and edit forms usually do
the right thing for simple cases, and more elaborate form
initialization is pretty straightforward.
