Then what's wrong with just doing:
widget=lambda field, value, row=row: lazy_options_widget(field=field,
on_key='no_table_master_field__selected',
off_key='master_field__unselected',
where=lambda master_field: (db.lookuptable.master_field == row.master_field
),
trigger=request.vars.master_field,
orderby=
db.lookuptable.id,
...
)
