You'll need to wrap the widget in someting that gets the attribute you
want. Try something along the lines of:
from operator import attrgetter
def attrwidget(attr, widget):
_get_attr = attrgetter(attr)
def getter(obj):
return widget.display(_get_attr(obj))
return getter
sortable_person_list = PaginateDataGrid(
fields=[
PaginateDataGrid.Column('name',
attrwidget('name', TextField('name')),
'Name',
options=dict(sortable=True)),
PaginateDataGrid.Column('age',
attrwidget('age', TextField('age')),
'Age',
options=dict(
sortable=True,
reverse_order=True)),
])
A bit too much redundancy (specifying 'name' three times) but it does
the trick
