just a suggestion :
in models : database uri, database migration, lazy tables, define table,
web2py built in menu
in controllers : import the module, using grid
in views : extend layout, and the variable return by controller
e.g. very easy n simple application (not more than 100 lines)
*models/db.py*
db = DAL('sqlite://shop.sqlite', pool_size = 30, check_reserved = ['all'],
migrate = True, fake_migrate_all = False, lazy_tables = True)
*models/db_wizard_0_bank.py*
db.define_table('bank',
Field('name'),
auth.signature,
format = '%(name)s')
*models/menu.py*
if auth.has_membership(role = 'Finance'):
response.menu += [
(T('Finance'), False, URL('default', 'index'), [
(T('Master'), False, URL('finance_master', 'index'), [
(T('Bank'), False, URL('finance_master', 'bank'), []),
]),

]

auth.requires(auth.has_membership(role = 'Finance'))(lambda: None)()
has_membership_manager = auth.has_membership('Manager')
editable = has_membership_manager

def bank():
return master.grid_0(db.bank, editable, deletable)

if db(db.auth_permission).isempty() and
db(db.auth_membership).isempty():
