[web2py] Re: autodelete image computed field
Any success on getting the computed thumbnail image to autodelete? I'm
having trouble with this too, where an update of a new thumbnail will not
delete the old file.

the problem is when i delete a row, image(big image) is deleteing from

any solutions are welcome :), thx

Hi,
How do I auto close a JS Bootstrap modal window that has simple form
and then update a grid on the calling main page??? I am using
Bootstrap modal window.
Model:
db.define_table('department', Field('name'))
db.define_table('office', Field('name'), Field('department',
db.department))
Controller:
def add_department():
form=SQLFORM(db.department)
if ..:

def add_office():
form = SQLFORM(db.office)
if ...:
...
else:
add_department.load:
{{=form}}
add_office.load:
{{=form}}
What I want in the view is to be able to add a company using a
bootstrap modal window after clicking on save close the modal window
and update a grid with a new company added in the same window. Also I
when i add office modal window, in the dropbox i want to see the just
added company without refreshing the main winnow but using ajax.
Any ideas pointer...thanx in advance...

Save your code into a file in the static folder, and include in your views

Re: [web2py] Re: Optimized way to use web2py Scheduler
Thanks Niphold for your informative response so If i understood correctly, in my case , I don't need to start 10 different workers as all these 10 tasks will have different time period to run hence one worker will be sufficient to perform the required tasks and in any case, suppose I have to run more than one tasks at the same time period then I should go to the approach of starting more than one workers.

Re: [web2py] Re: Optimized way to use web2py Scheduler
yep. The only limit to having a single scheduler for all your tasks is that it's allowed to have only one running task in a single point in time. NB: no task is discarded at all, only the concurrency is avoided, e.g.: if you have five tasks scheduled for 9.00 AM you'll get all your five tasks executed but they will be serialized one after another, so, let's say, the fifth one will be started on 9.05AM . If you have, e.g. two tasks that need to run every 5 minutes and each one takes 5 minutes to finish, one scheduler will not be able to perform all the iterations you need, so you need to start 2 of them. --

updated to sent to they are not included the next time the scheduler runs
the script.
This seems to work just fine.
It's when I inject a new message (which by default has a message status set
to unsent) via a bash script. The message inserts fine but my script that
posts it to the IRC channel doesn't not post anything but simply updates
it's status to sent without actually sending it. By sending it I mean post
a message over sockets.
Here is my model for sending unsent messages:

db.messages.message, db.messages.uid):
message_id = row.id
message_message = row.message
message_uid = row.uid
#socket connection already opened earlier in the script
s.send(PRIVMSG %s :%s - %s\r\n % (channel, message_uid,
message_message))
print message %s has been sent % message_id

[web2py] Re: OperationalError: database is locked
if you can, use a separate db for the scheduler. SQLite doesn't handle well
concurrent writes (with default operational capabilities), so having the
scheduler operating on the same database of your insertion of messages
can lead to locks.
Just do
db = DAL('whatever.db')
db2 = DAL('whatever_scheduler.db')
db.define_table('messages', .)
from gluon.scheduler import Scheduler
mysched = Scheduler(db2)
and to queue tasks you can then use
db2.scheduler_tasks.validate_and_insert()
or, with the new API
mysched.queue_task(***)

for sqlite =3.7 you can do

Re: [web2py] Re: Help with db query
Assuming that request.args contains the right values, this should work:
category = request.args[1].replace('_', ' ')
query = (db.Supplements.Category == category) ((db.Supplements.Users ==
request.args[0]) | (db.Supplements.Users == Both))
records = db(query).select()
Notes:
- contains does not work as it's intended only for fields defined as list
types,
- the alternative is to use belongs as Niphlod suggested yesterday.

[web2py] Capturing field changes with _after_update and smartgrid
I'm missing something. I have a table where I want to react to changes to a particular field. I'm trying to use the _after_update callback check for this. However, using this it appears to me that I am only seeing the data values after the update. I can't see what they were before the update so I don't know which fields we actually updated. Is there a 'bef'ore' buffer available that I'm missing? I'm trying to capture changes made using a smartgrid. Any tips would be appreciated. -Jim --

[web2py] Routing help with url helper
Hi,
i am having the basic routing where i omitted the application name in url.
Below is the content of my routes.py
default_application = 'init'
default_controller = 'default'
default_function = 'index'
routes_in = (
( '/$c/$f' , '/init/$c/$f' ),
( '/$c/$f/$anything' , '/init/$c/$f/$anything' )
)
routes_out = [(x, y) for (y, x) in routes_in]
But when i generate a url via URL helper
{{=URL(f='temp.json', hmac_key=, user_signature=True)}}
This will generate a URL with application name which means that application
name will be treated as controller and I will get a HTTP 404.
So either i create my URL manually, but then i wouldn't be able to use
digitally signed url or I should modify the routes.py which I am not able
to figure out without dropping the URL routing.
Also, I tried putting a=None and a='' in URL helper, still application
name is appending.
Thank you,

Re: [web2py] Re: Capturing field changes with _after_update and smartgrid
simple scientific thoughts. It's like databases triggers. Db triggers apply to the onupdate event, i.e. they let you use a set of just updated fields AND the fields that are going to be updated. Web2py has to intercept the update before or after, because databases (the python dbapi in general) don't expose that functionality. I rely on database triggers most of the times (as soon as I have access to the underlying database), but that's just because for simple things I'm faster on coding database triggers than python functions. However, with after_update, you can't scientific-ly know the values the rows had before the update, because the update has already happened. The stack works (I have in production several apps relying on web2py's triggers). After all, all your db(something).update() pass to the same function that applies - conditionally - the triggers. PS: if the update fails, then the trigger fails too if you don't do a db.commit() in the trigger itself. All web2py's operations are handled in transactions, so it's safe. Moreover, all the before_* triggers have the feature that if that function call returns True the update is not done kinda of an additional validation (I use that in business logics, e.g., you can't delete the default mapping for a particular product category) --
