Just replace render for display:
${name1.display()}
However, If planning to build a form, *don't* place your field
widget's in the template like this, use a form or else you'll lose
all advantages of input validation. If you need to precisely layout
your fields in the template you can:
a) Edit the form's template, *my* preferred method:
class MyForm(Form):
template = """
<form xmlns:py="http://purl.org/kid/ns#"; ...>
${display_field_for(item1)}<br /><hr />
${display_field_for(item2)}
</form>
"""
# the the template is somewhat simpplified, the form tag needs extra
attributes
b) Layout the fields in your page's template, good to work with
designers so they can edit the template file in their favorite editor:
-- controllers.py
@expose("mytpl")
def show_form(self)
return dict(myform=MyForm())
-- mytpl.kid --
<form ...>
${myform.display_field_for(item1)}
....
</form>
Sorry If this last piece of information wasn't what you were looking
for, I'm just guessing... ;)
