First of all notice that if you use web2py2.8.2 you can do this:
db.define_table('store_catalog',
Field('title'),
Field('slug',requires=IS_SLUG(),compute=lambda row:
IS_SLUG.urlify(row.title)),
Field('parent_id','reference store_catalog'))
def menu_rec(items): return
[(x.title,None,URL('action',args=x.slug),menu_rec(x.children)) for x in
items or []]
response.menu = menu_rec(db(db.store_catalog).select().as_tree())
And you get a recursive menu with arbitrary depth and a web interface to
edit it with slugs.
