In this situation look in the application/databases directory for a file with the table name as part of the file name. Remove or move the file somewhere else and then restart the web2py server. The table should now reappear and will be empty.
[web2py] Re: migrate=True not creating table ?
Hi Tom, Did you remove the table's .table file from the databases folder? The way I proceed this problem is: In the database's management tool delete/drop the table; Trash the table's .table file in the databases folder; In db.py set migrate to migrate='tablename.table' Save db.py Return to admin/default/design/appname Go to the database administration Return to db.py to set migrate to migrate=False Kind regards, Annet.
[web2py] Re: migrate=True not creating table ?
It's nearly working !
The table was dropped, I renamed the .table file, got
migrate='tabename.table', saved model.py and restarted the server.
I get this error :
class 'sqlite3.OperationalError'(near IGNORE: syntax error)
at the last field of the missing table line :
Field('FIN_CO1', label='Documentations', writable=False),
migrate='ficheIntervention.table')
with this Function argument list :
(self=gluon.dal.SQLiteAdapter object at 0x019E2EB0, *a=('CREATE
TABLE ficheIntervention(\n id INTEGER P...,\n FIN_VIS CHAR(512),\n
FIN_CO1 CHAR(512)\n);',), **b={})
It seems web2py is trying to create the table (Yay !), but not
succeeding.
The only ignore word I have in the database come from the
ondelete='ignore' I have on every reference in my table,
and it didn't prevent web2py from working before (worked for a week
with it, just fine, and with ondelete='ignore' active).
Any idea about what is happening ?

Hi,
I've created a component mycomponent.load to be used with the LOAD()
method. But inside the mycomponent.load I want to have a link to
another function in the same controller.
When I do: {{=URL(r=request, f='otherfunction')}}, the .load extension
is automatically added, so I end up being linked to the nonexisting
URL http://.../mycontroller/otherfunction.load;.
Is this the intended behavior? I can guess there is something about
the extension from this fragment of the book:
If you LOAD a component having the .load extension and the
corresponding controller function redirects to another action (for
example a login form), the .load extension propagates and the new url
(the one to redirect too) is also loaded with a .load extension.
but is there a way to remove the .load extension when using URL inside
a component?
Your component isn't redirecting, so this is not due to the propogation of
the .load extension upon redirect. However, the URL function will
automatically use the extension of the current request if the extension
isn't specified (unless the extension of the current request is html). Since
the request that loads the component has a .load extension, the URL function
will automatically add a .load extension as well. To avoid this, just
specify an explicit extension (e.g., extension='html'). Note, if you want
the link to point to an html page, but you don't want the resulting URL to
actually include the .html extension, then you can explicitly set
extension=False. In that case, web2py will default to requesting the .html
view (as it always does when there is no url extension), but it won't show
.html in the URL.
See near the end of this section in the
book:http://web2py.com/book/default/chapter/04#URL.

[web2py] Re: migrate=True not creating table ?
Getting the ondelete='ignore' away from the missing table
declaration let web2py create it.
The problem is I want the ondelete='ignore' to be here, so I'm
putting it back.
Another problem :
The DATE field seems to cause errors, when trying to read it. I'm
gettign an error :
type 'exceptions.AttributeError'('str' object has no attribute
'year')
when trying to show it in a SQLTable, or when filling a SQLForm with
an existing record.
In the Database, the field has written the date as 2007-06-05.
Err ... are DATE working correctly ?
Am I missing something (again) ?

thanks about the ondelete=NO ACTION, it's working ! actually, even ondelete=ignore works, if it is added after the table is created (even if it is not in the book).

Hum, actually, it's not working as I thought...

In your table definition the date field should be defined like this:

Re: [web2py] Re: Mobile detector
Nice work on that Angelo, I did have to change a few things, since 'dist' will not always exist (like when a non-Linux desktop machine visits). So this is what I did: When any 'dist' or 'os' returns is_mobile=True, then the result will have is_mobile at the root. So you can test for mobile like this: ua = request.user_agent() if ua.is_mobile: ... else: ... This should simplify things a bit. I also modified the simple_detect() method (in case anyone uses it) to return a third item in the tuple which is either True or False for is_mobile. I have attached the new user_agent_parser.py file so that you can test and confirm it works for you. If so, let me know and I will submit this for inclusion into the trunk. Nice job!

Re: [web2py] Re: Mobile detector
Hi Ross, I thought deeply on the implication on using the dist object. There are many points in favour: 1) Only dist object could be mobile ones from the code, Android - Iphone - Ipad are all dist objects. 2) If you want to detect Windows Mobile in a near future, you'll create a new dist object right? Then you can add the is_mobile flag there. 3) I think that is_mobile flag should be in dist object, because a Linux could have a dist like ubuntu whithout is_mobile or a dist like android whit is_mobile = True. I agree whit you that the is_mobile flag should be on root of the result object and not on a leaf object as dist, we could copy the flag if found at the end of detect phase. Furthermore I think that is a waste copying everey time the is_mobile flag to the root of result also when the useragent is not mobile. I think that the detect method should be like this: def detect(self, agent, result): if agent and self.checkWords(agent): result[self.info_type] = Storage(name=self.name) is_mobile = getattr(self, 'is_mobile', False) if version: result[self.info_type].version = version if is_mobile: result.is_mobile = \ result[self.info_type].is_mobile = is_mobile return True return False The getattr is really a speedy python operation and the if is_mobile is evaluated to True only one time, the one it founds a dist whit is_mobile = True.

Your web2py library is a forked (and tailored) version of official web2py 1.98.2. This way it will soon be outdated when web2py trunk grows into 1.99, 1.100, etc.. So I see the only practical way is: 1. modify your .flx file (in order to get rid of the public_html directory, shall we?) 2. and commit it into the trunk. 3. and then someone of us (if not Massimo) maintain an identical clone (rather than a fork) of web2py on github, until fluxflex will support google code as app backend someday. (Will they?) Later we will figure out a way to upload (perhaps download too?) each web2py app, one by one. By the way, how did you find out how to write the .flx file?

Re: [web2py] Re: User-friendly checkbox/radio-button widget in gluon/sqlhtml.py
Is all the JS just to get the dynamic highlighting? If so, I'm not sure it's worth adding to the framework. Instead, maybe just add a class to the label (or a wrapping span), and let the developer add dynamic highlighting or other effects if desired.

Hello,
I've noticed that the cleanup task in scheduler.py is not working for
me. Looking into it, it appears that the handling of time intervals in
MySQL through DAL is not being done properly.
This code
db(db.task_scheduled.status.belongs(statuses)) \
(db.task_scheduled.last_run_time+60now)._select()
generates the following sql
SELECT task_scheduled.id, task_scheduled.name,
task_scheduled.group_name, task_scheduled.status, task_scheduled.func,
task_scheduled.args, task_scheduled.vars, task_scheduled.enabled,
task_scheduled.start_time, task_scheduled.next_run_time,
task_scheduled.stop_time, task_scheduled.repeats,
task_scheduled.period, task_scheduled.timeout,
task_scheduled.times_run, task_scheduled.last_run_time,

((task_scheduled.status IN ('completed')) AND
((task_scheduled.last_run_time + '60') '2011-08-23 15:01:38'));
However, if I execute the following in MySQL:
SELECT last_run_time + '60' '2011-08-23 15:01:38' FROM
task_scheduled ORDER BY ID DESC LIMIT 1;
I get all zeros and MySQL even provides a warning about incorrect
DOUBLE value '2011-08-23 15:01:38'
If you do
SELECT '2011-08-23 15:01:38' + 60;
you also get this warning and the result is meaningless 2071.
Is this an error in the MySQL adapter for DAL or is the query missing
something to explicitly tell MySQL to do time interval arithmatic?

[web2py] Re: DB - removing reference when deleting referenced object...
Are you saying you want to do ON DELETE SET NULL (i.e., set the value of the reference field to NULL when the referenced object is deleted)? web2py Fields take an ondelete argument that defaults to CASCADE (which will delete referencing records when the referenced object is deleted). I suppose you could try ondelete='SET NULL' and see if it works. See http://web2py.com/book/default/chapter/06#Record-Representation (explains all the arguments to Field).

I have a table of results being displayed. There is a field in each row that contains information which I don't want visible in the actual table. I'd like a reveal link/button in that field of each row to pop up a modal window with the information which can then be dismissed. I don't want this information to be embedded within the page source itself, so the reveal link needs to be creating the modal popup and calling a function/URL that returns the info to be shown. Any pointers and/or code examples that might help me achieve this in a sane manner? :) Thanks! - Aaron

Hello,
I've noticed that the cleanup task in scheduler.py is not working for
me. Looking into it, it appears that the handling of time intervals in
MySQL through DAL is not being done properly.
This code
db(db.task_scheduled.status.belongs(statuses)) \
(db.task_scheduled.last_run_time+60now)._select()
generates the following sql
SELECT task_scheduled.id, task_scheduled.name,
task_scheduled.group_name, task_scheduled.status, task_scheduled.func,
task_scheduled.args, task_scheduled.vars, task_scheduled.enabled,
task_scheduled.start_time, task_scheduled.next_run_time,
task_scheduled.stop_time, task_scheduled.repeats,
task_scheduled.period, task_scheduled.timeout,
task_scheduled.times_run, task_scheduled.last_run_time,
task_scheduled.assigned_worker_name FROM task_scheduled WHERE
((task_scheduled.status IN ('completed')) AND
((task_scheduled.last_run_time + '60') '2011-08-23 15:01:38'));
However, if I execute the following in MySQL:
SELECT last_run_time + '60' '2011-08-23 15:01:38' FROM
task_scheduled ORDER BY ID DESC LIMIT 1;
I get all zeros and MySQL even provides a warning about incorrect
DOUBLE value '2011-08-23 15:01:38'
If you do
SELECT '2011-08-23 15:01:38' + 60;
you also get this warning and the result is meaningless 2071.
Is this an error in the MySQL adapter for DAL or is the query missing
something to explicitly tell MySQL to do time interval arithmatic?
Thanks,

Re: [web2py] Re: Mobile detector
Well, the reason is_mobile is in the base object is for polymorphism to work. If we later did do a WindowsMobile(Dist): class, we can easily set is_mobile = True in it, since Dist is a subclass of the DetectorBase. I just left is_mobile attached to the response even if it's not mobile because it makes it easier to test. Someone may test by trying if ua.is_mobile == False. So if is_mobile doesn't exist, it equals None and the test will fail. The routine runs pretty quickly. The thing that takes the longest is string searching.

Since src is a relative url, it will end up being
http://127.0.0.1:8000/tmp/rweb2output.png (assuming you're
running on your local machine on the default port). Instead, put
the file inside your application's 'static' folder (you can
create a 'tmp' subfolder in there), and use
src={{=URL('static','tmp/rweb2output.png')}}. Also, use an

Deploying web2py on a hosting server has never been so easy! (I start crying for the hours I spent in setting up my first web2py instance on my previous hosting provider.) One thing though. Your web2py library is a forked (and tailored) version of official web2py 1.98.2. This way it will soon be outdated when web2py trunk grows into 1.99, 1.100, etc.. So I see the only practical way is: 1. modify your .flx file (in order to get rid of the public_html directory, shall we?) 2. and commit it into the trunk. 3. and then someone of us (if not Massimo) maintain an identical clone (rather than a fork) of web2py on github, until fluxflex will support google code as app backend someday. (Will they?) Later we will figure out a way to upload (perhaps download too?) each web2py app, one by one. By the way, how did you find out how to write the .flx file?

[web2py] Understanding Rocket Threads
Hi,
First a little background: My application involves displaying and auto-
refreshing data both in the form of text from .load components and
dynamically generated images. I use JavaScript setInterval calls so
that ideally the refreshes should occur some time after the last
refresh completes. As it turns out, this does not work for the images
because using jQuery to update the .attr with the new img src returns
immediately, not after the image is loaded.
Anyway, the amount of time required to generate these images and text
data can be somewhat random, so I'm finding that my site will work for
a while, but eventually the long duration requests will pile up and
the site becomes unresponsive. Interestingly, the admin interface is
still as responsive as usual. I also notice that killing web2py will
not cause a clean exit, there will still be a thread working furiously
on the queued requests.
Thus it looks like rocket is using only one thread for the requests on
the main page, while the other threads sit idle and ready to service
other pages e.g. the admin interface. I tried to look through the code
of rocket.py to decide if this is indeed the case, but I wasn't able
to conclude one way or another. Since the admin interface is still
responsive, this does not appear to be an issue of the global
interpreter lock.
I found that starting many web2py servers on different ports, and then
directing the refresh calls to use a dedicated server for each data
source alleviated the problem somewhat, further suggesting to me that
only one thread is being used per session/browser/whatever to call it.
I expect to have no more than 2 users at a time for my application, so
I was hoping Rocket would be sufficient for this application. Would I
have better luck with apache or the like? I appreciate any advice on
the matter.
The code I'm using in the view to refresh the data is listed below

Hello,
I try to cache.ram a lambda represent function like Massimo suggest in
this post :
http://www.mail-archive.com/web2py@googlegroups.com/msg52736.html
My problem is that there record where the field to be represent is
empty...
I was using the and/or trick before like this that was working ok :
db.table1.create_by.represent=\
lambda value: (value!=None and %(initials)s
%db.auth_user[value]) or 'None'
But now, I want to speed my app a bit with cache.ram...
This work great as long as the field have been filled :
represent=lambda id: cache.ram('%id' %id,
lambda:db.auth_user(id).initials, 3600)
I try many different things, like :
represent=lambda id: cache.ram((id!=None and '%id' %id,
lambda:db.auth_user(id).initials) or 'None', 3600)
# NOT WORKING CAUSE : TypeError: 'int' object is not callable
represent=lambda id: cache.ram('%id' %id,
lambda:db.auth_user(id).initials if id!=None else 'None', 3600)
# NOT WORKING CAUSE : TypeError: %d format: a number is required, not
NoneType
Also try with function...
Any idea...
Thanks
