[web2py] Re: How do I get a controller to return back to the page that calls it (when it can be called by many pages)?
In your db_action() controller, rather than doing a return() at the
end, you could just redirect like so:
redirect(request.env.http_referer)

Hello All!
There is a database action that I want to do in several views.
Right now, I have it implemented as a link in each view as
a href=db_action?id={{=item_id}}Toggle Status/a
How do I get my db_action() controller to return back to the page
with the link that called it?
Is there a way to cause the browser to do the equivalent of the back
button?
Something like:
response.view = find_the_controller(request.env.http_referer)
return dict()
won't work because I'm not returning the proper dictionary for the
referring controller.
Maybe something like:
dict_from_referring_controller =
run_referring_controller( request.env.http_referer )
# ? do I have to define the response view?
return dict_from_referring_controller
Perhaps the nicest/cleanest implementation would be with AJAX/JQuery,
but I haven't learned that yet.
Is there a way to do it with a href links? Or is that super-bad
form?
Thanks!
Luis.

[web2py] Re: experimental in trunk...
I've got a working DAL connection that I can SELECT from. I'm running
into a problem with an update like so:
db(db.feed.id == f.id).update(last_update=now)
The row isn't updating and I'm not getting any errors. db._lastsql
shows this: UPDATE feed SET last_update='2011-05-25 20:40:56' WHERE
(feed.id = 1); Which updates just fine in the MySQL console.
Any suggestions?

then you can simply have this import
from dal import DAL
from dal import Field
or in a folder structure that can be seen as a package by your script
then you would simply do

On May 25, 9:47 pm, Massimo Di Pierro massimo.dipie...@gmail.com
wrote:
There are two more features in trunk that I could use some testing
with (common fields and precints)
Imagine you have created an app school designed to manage one
school. It has one database and many tables. You wrote it with one
school in mind. Now you want to turn it into a service so that
multiple schools can register and use it. You want to identify the
school for example by the urlhttp://harvard.anyschool.organd each
school should ONLY see its own users, groups, records, etc. etc.
Before today to do this you would have to rewrite all your tables and
queries.
Today you can do it without changing your code at all. You just have
to add this line after db=DAL(...)
db._common_fields=[Field('request_precinct',default=request.env.http_host,writable=False,readable=False)]
Yes. That is it!
How does it work?
1) db._common_fields is a list of fields that you want to add to all
tables.
2) The field called 'request_precinct' is special. Every query
involving a table having this field is automatically filtered byfield
value == field default. In our example the default is
request.env.http_host, i.e. the hostname in the http request which
identifies the school.
3) The field is hidden (writable=False,readable=False) but has a
default therefore it is automatically set for all inserts.
There is nothing special about schools here. You can use it with any
other app.
Give it a try and let me know.
I could use some help in writing some documentation about the new
features added today. ;-)

[web2py] Re: develop iphone apps with web2py with this plugin
I started building mobile views using jQuery Mobile just a few days before you released this. For the most part we did the same things, but I have a bit of code that in models/0.py that checks for a mobile user agent and adjusts the view accordingly. This way I can use the same controller for both the regular view and the mobile view. The normal view would be at index.html and the mobile view at index.mobile.html. You'll need mobile.sniffer and PyWURFL modules for this to work.

[web2py] Re: Insert blank record crashes in sqlite
I'm not able to find anything SQLite specific, but this is what the MySQL docs say about empty rows: If both the column list and the VALUES list are empty, INSERT creates a row with each column set to its default value: INSERT INTO tbl_name () VALUES(); In strict mode, an error occurs if any column doesn't have a default value. Otherwise, MySQL uses the implicit default value for any column that does not have an explicitly defined default.

[web2py] Re: Web2py and message queue's
Instead of using a database table as an intermediary you should take a look at using an actual message queue. I'm personally using BeanstalkD with the BeanstalkC python module. When a new message is created, you could create a bit of JSON that contains the message and the list of recipients. Then you would have a python worker process script that would wait for new messages and it would take care of actually sending the email/sms. http://kr.github.com/beanstalkd https://github.com/earl/beanstalkc Matt On May 9, 6:13 am, villas villa...@gmail.com wrote: I once set something up with this kind of functionality. Simplified concept was: 1. Two tables, e.g.: Messages: subject, body MessQueue: to_id, from_id, message_id, dest, stat, sent_on note: dest is either an email address or mobile tel no. 2. A message is created and multiple recipients chosen. For each recipient an entry is made in the messqueue table. 3. A background script (outside web2py) polls the messqueue and sends message via email or text message. Result is stored in stat field. 4. In addition to receiving the messages via email/text, each user can see a list of their messages when they log on.
