Can custom_store and custom_retrieve take parameters when they are called
using Field, e.g.:
db.define_table('table',
Field('file', 'upload', custom_store=store_file(file,
db.table.new_filename),
custom_retrieve=retrieve_file(db.table.new_filename))?
Field('new_filename','string')

Do your smartgrid forms require you to be logged in? The add buttons won't
show unless you're logged in...

Thanks for the helpful clarification! However, neither method will
