Massimo, this is cute, but it only works on Chrome. If you could grant

[web2py] Problem using MySQL with scheduler.py
Hello,
I just tried to use scheduler.py with MySQL instead of SQLite and ran
into this error:
NotSupportedError: (1235, This version of MySQL doesn't yet support
'LIMIT IN/ALL/ANY/SOME subquery')
The MySQL server version is 5.0.77. Searching on the web, it seems
this limitation is common. Is there a way to work around the issue?
The offending SQL looks like this:
UPDATE task_scheduled SET
status='running',assigned_worker_name='crabby#237cf3f0-89e7-4db5-
b514-56db27a700d5',last_run_time='2011-08-13 09:33:01' WHERE
(task_scheduled.id IN (SELECT task_scheduled.id FROM task_scheduled
WHERE (task_scheduled.enabled = 'T') AND (task_scheduled.status =
'queued')) AND (task_scheduled.group_name IN ('command','main'))) AND
(task_scheduled.next_run_time '2011-08-13 09:33:01')) AND

[web2py] Enable and disable buttons
I'm trying to make a web2py app in which users have to insert a lot of different types of data. Once all the data have been added the user should be able to click on a button to get the app to elaborate the data and produce the final output. What would be the simplest way to disable the button until all the relevant data have been added, and to activate it automatically once everything is ready? Or would you suggest a different type of approach altogether? Michele

[web2py] MySQL query not reflecting actual state of db
Hello, I am using a loop like this to wait for a scheduled task to complete: query = schdb.task_scheduled.id == id query = ((schdb.task_scheduled.status == 'queued') | (schdb.task_scheduled.status == 'running')) while schdb(query).count(): time.sleep(0.1) #wait for task to run This worked perfectly when schdb was on SQLite, but now I am using MySQL so the workers can run on different machines. The loop goes on forever. If I display the contents of schdb(query).select() in the loop, I see that it does indeed continuously show the status is 'running'. However, when I look at the database with MysQL Query Browser, I can see that the task completed normally and updated the status to 'completed'. I checked to make sure there are no missing db.commit() statements. Any ideas what could be causing schdb(query) to not reflect the true state of the database? Thanks, G

[web2py] Virtual Fields. Strange behavior when saving db result sets Build in types
Hello,
I have the following definitions in db.py
class ElectionVirtualField(object):
...
def is_presidential(self):
def lazy(self=self):
return self.election.category == 'P'
return lazy
...
db.define_table('election',
...
Field('category', length=1, label=T('Category')
...
The problem I have is that when I add a bunch of elections in dict()
(key = election.id, value = election row) and then traverse the dict,
I get wrong values from is_presidential()
Example:
elections = dict()
for election in db(db.election).select():
elections[election.id] = election
for (k, v) in elections.items():
print k , ' ', v.category, ' ', v.is_presidential()
Output:
81 D True
79 P True
As you can see, it returns True for both, but for the first one, it
should return False.
If I change the code to reload the election from the database, the
output is different:
Example:
elections = dict()
for election in db(db.election).select():
elections[election.id] = election
for (k, v) in elections.items():
reloaded_election = db.election(k)
print k , ' ', v.category, ' ', v.is_presidential()
Output:
81 D False
79 P True
Does this mean that we can't save rows from DB on Build in types ?
Thanks in advance,
Santiago

[web2py] Re: MySQL query not reflecting actual state of db
Hello again,
It seems that db.commit() is necessary to get the query to reflect the
changed state of the database for some reason.
The simple code at the end of this message illustrates the problem.
Starting two ipython sessions, and running side1() in one, and then
side2() in the other, if the db.commit() line in the side1 loop is
removed, it will loop forever even though the database is actually
updated by side2.
This work around works, but I'd like to understand what's going on.
Thanks,

Re: [web2py] how to generate PDF (with data) using PDF static forms?
I think that not even ReportLab could merge an existing PDF, IIRC
there are other tools to open and possibly modifiy files.
If you can make your design and fill it, then you can use PyFPDF
(there is an Invoice example).
Also, sometimes I put an image as background (+-300dpi) and then I
only complete the text fields.
YMMV

[web2py] Re: Problem with multiple forms
Each form needs to have a unique name. I suppose you could use uuid to
make a unique name. Then something like this pseudocode might work:
allforms=dict(form_id=new_form_id(),form=SQLFORM(...))
for f in allforms:
if f['form'].accepts(request.vars,formname=f['form_id']):
# do something if form accepts
else:
# do something else if form doesn't accept
return dict(allforms=allforms)
Then in views you will need to loop on allforms to make your form. You
will probably want a custom form and make sure you have a hidden input
with id=f['form_id']
Obviously, if the order of forms is important, you will want to modify
this code to make the forms into a list instead of a dict.
Hope this helps. Good luck.
