This is the code in my controller
form = SQLFORM.factory(Field('list_name', 'string', label='List Name'), db.
project, table_name='project',upload=URL('download'))
for t in db.project:
query = (t.id == request.vars.id)
__copydata(db(query).select(limitby=(0,1)).first(), form.vars, t.fields)
and this is in view
<div>{{=form}}</div>
