[web2py] last_run_time as argument for a scheduled function
Hi, a question about the scheduler: The scheduler calls a function f() 12 times per hour. db.scheduler_task knows the last_run_time and next_run_time. I want to call the function f with these two values as arguments. Is there a simple way? Regards, Martin --

[web2py] Re: last_run_time as argument for a scheduled function
absolutely not clear what you want, but i guess a simple db(db.scheduler_task.function_name = 'yourfunction').select(db.scheduler_task.next_run_time, db.scheduler_task.last_run_time) will fetch the values to use in that function call you need.

[web2py] compute field doesn't work on update
Other users have the same problem and, sorry but I can't find my solution;
i tried with readable=true and writable=true, to update all the field
interested in the compute function, to comment the line in DAL.py, but
nothing.
I have this table:
db.define_table('magazzino',
Field('id_tipo', 'integer',default=0),
Field('p_p','double', default=0.0),
Field('pp_tot','double', writable=True, readable=True, compute=lambda
r: r['id_tipo']==0 and r['p_p']*1 or r['p_p']*r['id_tipo']*-1),
)
If I edit a row with a FORM the compute field works but if I edit it in a
function with ajax don't...
def modArtPrice():
newPp = 100
articolo = db.magazzino[request.vars.id]
articolo.id_tipo=articolo.id_tipo

what version do you have? Something else is wrong.
By the way your code contains some hidden characters:

[web2py] Re: Exposing validators as JSON?
+1
would a 'json:reference mytable' field type similar to 'list:reference
mytable' or perhaps a format=lambda row: row.json() be possible?

That would be cool, perhaps you could add a class to the fields and key
off the classes. Or, have the validation function append error messages to
a list and return that as json?

How do I expose validators as JSON?
I am not using web2py views in any capacity. Instead I am using
AngularJS.
So with web2py I am exposing my models RESTfully as JSON, and then
consuming them with AngularJS.
To reduce double-typing, how do I send field validators such as
`IS_EMAIL` as JSON?
# Model
db.define_table(
'foo',
Field('email', requires=IS_EMAIL())
)
# Controller
@service.json
def foo_form():
return dict(my_foo_form=crud.create(db.foo))
# Output I want
{ 'my_foo_form': { 'type': 'form', 'fields' { 'email',
'validator:IS_EMAIL'}, 'csrf': uid } }
With this I can then write the equivalent functions in JavaScript and
attach them to their corresponding fields.
How do I do this with web2py?
Thanks for all suggestions,
Alec Taylor

Its high on our list as well. That plus a denser edit/create/view layout similar to Scubism's Solid Form. --
