[web2py] Re: form fields
SQLFORM shows the values of non-writable fields but does not put those values into HTML form widgets, so they are not submitted with the form. A couple of options: - Instead of setting writable=False, specify a custom widget for the fields with the HTML readonly attribute set to true (e.g., widget=lambda f, v: SQLFORM.widgets.string.widget(f, v, _readonly=True)). With this approach, be sure to validate the non-writable values as well, as a malicious user can still submit modified values. - Create a separate object (e.g., a DAL Row) containing the non-writable field values, and make that object available within the onvalidation function (since those values are not changeable within the form, there is no reason the values must come from the form submission).

[web2py] Re: Form fields in DB showing a 0 value
Niphold, thanks for that info, but this is what I have;
db.define_table(
'order_bus',
Field('depart_from'),
Field('arrive_to'),
Field('date', 'date'),
Field('time', db.depature_times), # drop-down select time options
Field('no_of_passengers', db.tickets), # drop-down options to select
number of positions
Field('posted_on', 'datetime', readable=False, writable=False),
Field('posted_by', readable=False, writable=False))
db.order_bus.depart_from.widget = SQLFORM.widgets.autocomplete(request, db.
route.city, id_field=db.route.id, limitby=(0,10), min_length=2)
db.order_bus.arrive_to.widget = SQLFORM.widgets.autocomplete(request, db.
route.city, id_field=db.route.id, limitby=(0,10), min_length=2)
I like to point out that something very strange happens;
When I select the depart_from and arrive_to fields, the auto complete
options appear, and then I can choose a city. When the form is submitted,
the route.id for the arrive_to field that was selected on the form, appears
in the depart_from column in the order_bus db table. In addition to that,
the arrive_to db table table shows 0. So I am not sure as what is really
going on.

You need to pass the id_field argument

[web2py] Re: Form fields in DB showing a 0 value
please use format as record representation or set it on IS_IN_DB form
validation.
e.g. if you want to show city as a drop down menu in order_bus form :
db.define_table(
'route',
Field('city'),
Field('country_iso'), format = '%(city)s')
db.order_bus.depart_from.requires = IS_IN_DB(db, 'route.id', '%(city)s', zero
= T('choose one'))
db.order_bus.arrive_to.requires = IS_IN_DB(db, 'route.id', '%(city)s', zero
= T('choose one'))
