I asked the same question in the web2py-users-brazil<http://groups.google.com/group/web2py-users-brazil?hl=pt-BR> .
And this was the suggestion: ########################### db.t_hospital.f_group.requires = IS_IN_DB(db.t_city, 't_city.id', db.t_city.f_group, zero=T('[Choose an item from the list]')) db.t_hospital.f_city.requires = IS_IN_DB(db.t_city, 't_city.id', db.t_city.f_name, zero=T('[Choose an item from the list]')) ########################### But I have an error: --------------------------------------------- Traceback (most recent call last): File "/home/www-data/web2py/gluon/restricted.py", line 194, in restricted exec ccode in environment File "/home/www-data/web2py/applications/indicadores/controllers/ default.py", line 39, in <module> File "/home/www-data/web2py/gluon/globals.py", line 149, in <lambda> self._caller = lambda f: f() File "/home/www-data/web2py/gluon/tools.py", line 2456, in f return action(*a, **b) File "/home/www-data/web2py/applications/indicadores/controllers/ default.py", line 26, in hospital_manage form = SQLFORM.grid(db.t_hospital,onupdate=auth.archive, columns=columns, details=True, editable=True, deletable=True) File "/home/www-data/web2py/gluon/sqlhtml.py", line 1445, in grid _class='web2py_form' File "/home/www-data/web2py/gluon/sqlhtml.py", line 862, in __init__ inp = self.widgets.options.widget(field, default) File "/home/www-data/web2py/gluon/sqlhtml.py", line 217, in widget options = requires[0].options() File "/home/www-data/web2py/gluon/validators.py", line 459, in options self.build_set() File "/home/www-data/web2py/gluon/validators.py", line 440, in build_set fields = [f for f in self.dbset.db[self.ktable]] File "/home/www-data/web2py/gluon/dal.py", line 4921, in __getattr__ return self[key] File "/home/www-data/web2py/gluon/dal.py", line 4865, in __getitem__ return dict.__getitem__(self, str(key)) KeyError: 'db' --------------------------------------------- 2011/11/17 DenesL <denes1...@yahoo.ca> > > It sound like you need to create three tables instead, > one for cities, one for groups and one for city-group combos. > > On Nov 17, 6:52 am, Renato Ramiro <renato....@gmail.com> wrote: > > In my application, I have two tables: City and Hospital. > > > > In the table City, there are two fields: name and group. > > And the table Hospital, there are name, number of beds, number of medics, > > and city (foreign key). > > > > Through the wizard, I did this (below): > > > > Field('f_city', type='reference t_city', > > label=T('City')), > > > > And manually I added this (below) > > > > Field('f_group', type='reference t_city', > > label=T('Group')), > > > > At the moment of creating a Hospital, I have two combobox.
