Hello everyone! --------------------------------------------------------------------------------------------------------------------- This is my model: db.define_table('autori', Field('nome_autore', 'string', length=300), Field('bio', 'text'))
db.define_table('case_discografiche', Field('nome_casa_discografica', 'string', length=300), Field('bio_casa_discografica', 'text')) db.define_table('generi', Field('genere_musicale','string', length=300)) db.define_table('songs', Field('titolo', 'string', length=300)) db.define_table('albums', Field('autore', db.autori), Field('titolo', 'string', length=600), Field('genere','string', length=300), Field('tracklist','text'), Field('casa_discografica', db.case_discografiche), Field('copertina', 'upload')) db.define_table('songs_albums', Field('song_relation', db.songs), Field('album_relation', db.albums)) db.autori.nome_autore.requires = IS_NOT_EMPTY(), IS_LOWER(), IS_NOT_IN_DB(db, 'autori.nome_autore') db.case_discografiche.nome_casa_discografica.requires = IS_NOT_EMPTY (), IS_LOWER(), IS_NOT_IN_DB(db, 'case_discografiche.nome_casa_discografica') db.generi.genere_musicale.requires = IS_NOT_EMPTY(), IS_LOWER(), IS_NOT_IN_DB(db, 'generi.genere_musicale') db.albums.autore.requires = IS_IN_DB(db, db.autori.id,'%(nome_autore) s') db.albums.titolo.requires = IS_NOT_EMPTY(), IS_LOWER() db.albums.genere.requires = IS_IN_DB(db,db.generi.id, '% (genere_musicale)s') db.albums.casa_discografica.requires = IS_IN_DB (db,db.case_discografiche.id,'%(nome_casa_discografica)s') ---------------------------------------------------------------------------------------------------------------- A song can be in many albums and an album has many songs so we need a many to many relationship here. For this reason I've created the table "songs_albums" where there are relationships between albums and songs. But I can't figure out how to update this relationship table using crud! Can you help me please? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "web2py-users" group.
