This is in trunk but instead of
db.define_table('person',
Field('name'),
Field('gender'),
Field('birthdate', 'date'))
db.define_table('animal',
Field('name'),
Field('gender'),
Field('birthdate', 'date'))
# Bind the function to tables.
# Note the use of "self".
# Due to this decorator, we're "inside" the instance.
@make_member_of(db.person, 'just_men')
@make_member_of(db.animal, 'just_males')
def get_just_gender_equals_m(self):
return self._db(self.gender == 'm').select()
# Use the function as a regular table method.
db.person.just_men()
db.animal.just_males()
You instead do:
@db.person.add_method.just_men
@db.animal.add_method.just_males
def get_just_gender_equals_m(self):
return self._db(self.gender == 'm').select()
db.person.just_men()
db.animal.just_males()
I really love this!
