CONTROLLER
I think I kinda figured out the problem. The order of defining tables
seems matter. Tables to be referenced need to be defined before the
referencing tables. Guess it's a rookie mistake.
I don't think it's a matter of table definition order. Maybe there aren't
any referenced records in
I did added it in grid, my controller is :
@auth.requires_login()
def rent():
grid=SQLFORM.grid(db.company, user_signature=False,
editable = auth.has_permission('edit','auth_user'),
deletable = auth.has_permission('delete','auth_user'))
return
well, when you plan to use cache you do it because:
a) the additional roundtrip is negligible
b) using the cache means your database is not used
I'll explain it further
A query that takes 0.18ms to get computed on the database side can very
well end up in 18sec as soon as your database gets

Thanks for the very clear explanation.
I made the following:
t0 = time.time()
rows = cache.memcache ('q1', lambda : q1(query))
t1 = time.time()
rows2 = cache.memcache('q2', lambda: q2(query))
rows2 = [r for r in rows2 if (r.end_point.gathered_on -
r.start_point.gathered_on
so, q1 is now always faster than q2 ... seems that the bits you were
missing are in fact the ones that auto-set the cache-key based on the query
string
cache.ram is always faster than anything else, cause it stores a pointer to
the result, doesn't have to pickle/unpickle the result and

As I understand it, the table does not have to exist when using the
'reference sometable' syntax. Or anyway that's how it's supposed to work.
I'm not 100% confident in it, though so I always make it a practice to
create the reference tables first.
On Monday, March 25, 2013 6:31:16 AM UTC-4,
In your function you can do db.whatever_table._enable_record_versioning()
. Record versioning is automatic on update so you can still use your
original onupdate callback.
check here and search for 'archive'

Dear all,
I started to use scheduler. I've created a simple starting example task:
https://github.com/ilvalle/scapp/blob/master/models/scheduler.py
and with the great niphlod's plugin cs_monitor_plugin I created an initial
repetitive task.
However, although I set repeats: 0 and period: 300,
I think the period starts as the last execution ends.
Sometimes I miss the feature to start the task exactly at fixed interval
rater than fixed interval starting after the last run ends but I can live
without it. :) It's a great tool anyway :-D
