[web2py] Is it possible to LOAD a component after a page has rendered?
I'd like to asynchronously load one of a choice of components into a
view, based on a user selection after the page has loaded. It's
relatively trivial to do this by changing the src on an iFrame which
embeds the component view, but this doesn't feel like a web2py-ish way
of doing things.
It would be great to be able to do something like pass the component
to the view in the form something like (obviously this is currently
impossible):
LOAD('controller','function.load',target='componentTarget',deferRender=True)
Then do a js call:
$('#componentTarget').render()
to create the component on the page.
Any ideas?

web2py_ajax_page("get", URL, null , DIV_ID)
This function is included in web2py.js

[web2py] Re: Is it possible to LOAD a component after a page has rendered?
You can use javascript onclick and the web2py.js function web2py_component(action,target) to load the source on demand. You need to set a target div or other element in the view previously and get the triggered event's DOM element id with jQuery to pass it with the url/action string.
[web2py] DAL and date calculations
Using the DAL, I'd like to select records that are less than some interval old, or newer than a certain date. My records have a datetime field in them. So I want something like: select * from table where mydate > (now()-interval 1 day) Can I do this in the dal, or do I have to use raw sql? Thanks, Ed

[web2py] Problem with the audio tag, web2py and Firefox
I recently read a book about html 5 and promptly started using some of the
features described in my project.
I experienced a problem with the audio tag and Firefox which I reduced to a
minimalistic example illustrating the problem.
*The experiment:*
*1) Control Situation*
I put "Main_theme.webm" and "Main_theme.mp3" in a folder along with
test.html which is written as follow:
HTML5 Audio
Just because you are getting older doesn't mean your browser has
to. Go get a recent browser and get a youthful feeling!
The soundtrack plays for Opera, Chrome, IE and Firefox (in Safari, the
soundtrack doesn't play and the message appears instead which is weird as
www.caniuse.com lists audio tags as supported in recent versions of safari,
but anyways, this is a side detail).
*2) Deployment Situation*
I put the "Main_theme.webm" and "Main_theme.mp3" audio files in the
/static/audio directory.
I use the default Tornado server that comes with the Framework.
I edit the index.html page of the default controller to be:
{{extend 'layout.html'}}
Just because you are getting older doesn't mean your browser has
to. Go get a recent browser and get a youthful feeling!
Here, the result is the same as the control situation, expect for the fact
that the soundtrack doesn't play in Firefox.
When I look at the http requests/responses in Firebug, I see a 206 code for
the audio file request (which is the same as in Chrome, expect that Chrome
plays it).
So, what is faulty? Me? Firefox? Web2py? The Tornado server? A combination
of the previous?
Any insights would be welcome.
I won't die if the audio for my app doesn't play with Firefox, but it would
be nice.
[web2py] ssh tunnel to admin panel with lighttpd=> ERROR:web2py.cache:corrupted file
Hello guys, Attracted by web2py dev possibilities I couldn't resist ;-) But unfortunately deployment is a whole other story and I'm having major difficulties. So after a struggle I got web2py to run on lighttpd, then discovered that, as I didn't set any SSL, I couldn't access the admin interface. So I'm trying to use an ssh tunnel : ssh -L 9090:localhost:80 root@192.168.1.101 After that I can see the demo app at localhost:9090 but every single click on the "Admin interface" button on the right of the demo app end up with : on the browser side : "Internal error Ticket issued: admin/__1.2012-01-28.23-18-18.cf854d0b-a8f7-4ef8-bd28- a24debe031a8" on the terminal side (the terminal which started a bash script starting the fcgihandler.fcgi ) I got this : ERROR:web2py.cache:corrupted file /home/www-data/web2py/applications/ admin/cache/cache.shelve, will try delete it! Interesting fact : each time I try to click on the "admin panel" button from the browser, a new "ERROR:web2py.cache:corrupted file / home/www-data/web2py/applications/admin/cache/cache.shelve, will try delete it!" is displayed on the terminal. What am I doing wrong ? Thanks a lot, cheers, PS : the file got deleted automatically each time but I still can't access the admin panel
[web2py] Re: ssh tunnel to admin panel with lighttpd=> ERROR:web2py.cache:corrupted file
Can you try delete applications/admin/cache/*? it is possible that there is a cache file created using a different python version and web2py cannot open it. For permission issues it may be unable to remove it and re-create it.

[web2py] reload just via ajax (not entire page)
I have an observation. When we jump from one view to another, the entire page gets reloaded. Whereas, it should be sufficient to reload just via ajax. Any particular reason as to why the entire page is reloaded every time? For my purpose, on every request, how do I load only via ajax?
Re: [web2py] reload just via ajax (not entire page)
I am pretty sure every page is reloaded every time is because their is no guaranty that every single person who uses the framework will use a div id="page" etc... or the same layout for that matter. If you want to refresh only the then you would have to write your application in a way so it does that. IE: Intercept page clicks with javascript, and make sure your view contains only the HTML you want to render inside don't include the layout template etc.. Then use jquery to update the html of the with the new content. -- Regards, Bruce On Sat, Jan 28, 2012 at 12:15 PM, Vineet wrote: > I have an observation. > When we jump from one view to another, the entire page gets reloaded. > Whereas, it should be sufficient to reload just via > ajax. > > Any particular reason as to why the entire page is reloaded every > time? > > For my purpose, on every request, how do I load only > via ajax? -- -- Regards, Bruce Wade http://ca.linkedin.com/in/brucelwade http://www.wadecybertech.com http://www.warplydesigned.com http://www.fitnessfriendsfinder.com

[web2py] Any advice on spam control for a comment system?
I'm about to deploy a simple blog platform for myself and have implemented comments using something very much like Massimo's example in the components chapter of the web2py book. What I'm wondering about, though, is spam control. At the moment I think I'm just going to activate recaptcha for the comment submission form. But has anyone got other suggestions? I understand that "honeypot" solutions are often effective, but I haven't yet thought about how to implement one. Ian

[web2py] Re: reload just via ajax (not entire page)
Because that's how 99.9% of websites function.
[web2py] Re: Any advice on spam control for a comment system?
I would suggest avoiding captcha until you prove to yourself that you have a problem. Akismet is targeted at comment spam in particular: http://akismet.com/ If you do need something, captcha is probably the worst choice you can make since it's aggravating to legitimate users. Here's a simple hidden field explanation: http://www.ngenworks.com/blog/invisible_captcha_to_prevent_form_spam/

Re: [web2py] Web2py in large web scenarios
submodels are good, but you cant import models. So you cant reuse code. you end with too much repetition. in modules you can have a DRY structure. https://github.com/rochacbruno/web2py_model_less_app http://zerp.ly/rochacbruno Em 28/01/2012 23:00, "Vinicius Assef" escreveu: > I'd use folders inside models. > I think I'd use web2py infrastructure that's already available to me. > > And, AFAIK, /modules were not planned for that.
