Well, it's best to render fields from a formulator form using the
element's member function .render().  You can pass a string value to
it to set that form element's value attribute, if applicable, or
recreate what the user submitted with the form, by using
.render_from_request(request).

However, if you're looking to get the Id of the formulator element:

field.getId()

and if you need the name of the field to have the 'field_' prefix, use
a python expression and concatenate to the Id.

'field_' + field.getId()

HTH.
