Hello.
I've make a many to many to many relationship but I've got problems on
select results.
Is it the correct way to do it?
My DB:
db.define_table('ceo_schemes',
Field('name', type='string', requires=IS_NOT_EMPTY()),
format='%(name)s')
db.define_table('overrides',
Field('name', type='string', requires=IS_NOT_EMPTY()),
format='%(name)s')
db.define_table('override_codes',
Field('code1', type='string'),
Field('code2', type='string'),
format='%(code1)s %(code2)s')
db.define_table('ceo_schemes_and_overrides_and_override_codes',
Field('ceo_scheme', 'reference ceo_schemes'),
Field('override', 'reference overrides'),
Field('override_code', 'reference override_codes'))
My controller:
override =
db((db.ceo_schemes_and_overrides_and_override_codes.ceo_scheme ==
ceo_scheme.id) & (db.ceo_schemes_and_overrides_and_override_codes.override
== override_id)).select()
In my view I can see this result with BEAUTIFY(response._vars):
override:"ceo_schemes_and_overrides_and_override_codes"."id"
"ceo_schemes_and_overrides_and_override_codes"."ceo_scheme"
"ceo_schemes_and_overrides_and_override_codes"."override"
"ceo_schemes_and_overrides_and_override_codes"."override_code"302_DWithout
20
But in the controller if I call:
override_code =
override.ceo_schemes_and_overrides_and_override_codes.override_codes.code1
The ticket is :
'Rows' object has no attribute
'ceo_schemes_and_overrides_and_override_codes'
Someone knows why? Is is the way that I've done the 3 tables relations ship
that's wrong?
Thanks.
