db.tablename.fieldname.readable = False # SAFE
def test():
db.tablename.fieldname.readable = False # NOT SAFE
*models.py*
def on_define_tablename(table):
table.fieldname.readable = False # SAFE
db.define_table('tablename',
Field('fieldname'),
on_define = on_define_tablename)
BUT things like on_define = on_define_tablename
are no longer necessary in web3py. Tables are defined when the files are
imported not at every request (like in web2py) and therefore you do not
need optimization tricks any more.
