Change field names in Python WTForms -

so got form exists of repeating row of fields, it's defined this:

class simpledatarow(form):     title = stringfield('title')     label = stringfield('name')   class simpledataform(form):     fields = fieldlist(formfield(simpledatarow)) 

after initialize form, , append entries corresponding data:

fields = dbsession.query(field).filter_by(app=request.currentapp).all()  form = simpledataform() field in fields:     form.fields.append_entry(field) 

then want render fields browser, trouble because of field naming in wtforms. when rendering fields assigned name , id of fields-0-title & fields-0-label, , each row of data 0 incremented 1.

what rather have wtform takes id of field object, , uses when assigns names , id's fields. field object looks this:

class field(base):     __tablename__ = 'sys_fields'     id = column(integer, primary_key=true)     label = column(string(64))     title = column(string(64)) 

so there way change pattern wtforms uses name fields in fieldlist's? ideally want naming pattern this: {prefix_}{label}_{id}

you can give prefix when instantiating form class. in case like:

form = simpledataform(prefix=<your prefix string>)
