I'm trying to create library system and have a little problem. Here's my
current model:
db.define_table('tags',
Field('name'),format='%(name)s')
db.define_table('copies',
Field('is_active','boolean',default=True))
db.define_table('book',
Field('title',requires=IS_NOT_EMPTY(), label='Tytuł'),
Field('author', requires=IS_NOT_EMPTY(), label='Autor'),
Field('isbn', 'integer', requires=IS_LENGTH(13), label='ISBN'),
Field('release_year', 'integer', requires=IS_INT_IN_RANGE(-3000,
request.utcnow.year+1), label='Rok wydania'),
Field('format', label='Format'),
Field('cover', 'upload', requires = IS_EMPTY_OR(IS_IMAGE()),
label='Okładka'),
Field('publisher', label='Wydawca'),
Field('tags', 'list:reference tags', label='Tagi'),
Field('copies', db.copies),
auth.signature)
db.book.tags.widget = SQLFORM.widgets.checkboxes.widget
Here is what I want to achieve: when a user adds new 'book' table record,
he types number of copies of that book and that amount of records is
automatically created in 'copies' table. Then a user will be able to loan a
specific copy of a book (i will probably be able to figure this part out
thanks to library example) but only for specific period. If you have other
ideas on how to solve my problem, please share.
Also less important but i would like to change the style of my tags widget,
so it would display either set number of tags per row or just display
maximum number that will fit in screen.
Thanks in advance for all replies.
