web2py + Apache + wsgi(Uniform Server) failed for the latest 2.9.12

It has been a long time since I setup the web2py server and they are still running 2.4.6. I decided to refresh my memory and version up!


Then I'm failed.

See the forum below.!topic/web2py/yBM8Ybl_xGA

It sounds like the latest web2py 2.9.12 doesn't work with apache using wsgi.

I already posted a ticket here.

If your server configuration is something similar to me, I recommend wait until this ticket is fixed!

web2py Dynamically change highlighted class for

I'm trying to add simple function to my website but didn't know what to do. Niphlod provided me the snippet in web2py forum so I can share it here!

1. Create new app called "highlight"

2. Overwrite the in = [
    (SPAN('Home', _id='default_highlighted'), False, URL('default', 'index'), []),
    (SPAN('Menu1'), False, URL('default', 'menu1'), []),
    (SPAN('Menu2'), False, URL('default', 'menu2'), [])

3. add the following script right before </head> in layout.html

jQuery(function() {
  var path = location.pathname.substring(1);
    if ( path ) {
        var els = jQuery('ul.nav a[href$="'+path+'"]').filter("[rel!=nofollow]");
        if (els.length != 0) {

        } else {

4. Create empty action in controllers/ for test purpose

def index():
    return dict('')

def menu1():
    return dict('')

def menu2():
    return dict('')

5. And empty views default/menu1.html and default/menu2.html

web2py jquery mobile plugin

So this year I'm trying to work on mobile development. I realized it's hard for me to learn all the language for the native app for each platform (apple, android, blackberry...etc) and found jQuery Mobile. It's so cool how come I didn't know about it!

I finished reading the book and What?? web2py already has the plugin !! OMG, I love web2py.

You can download it from here.

Thank you, Jason, Timothy, Harkirat and Massimo.

As of today, there is a issue and you will get blank page when you install the plugin.
I already submit a ticket (#1354: jQuery Mobile Plugin layout issue) with the solution.

Yeah! It looks great !!

web2py grid with export dropdown

I just want to share the code that Paolo Caruccio created to show the export dropdown for grid instead of links. It looks very clean and this should be the default for grid layout!

web2py forum link!topic/web2py/HsFWsQmGONM

To test, create new app and add/edit as follows.


    Field('Code', 'integer'),


def index():
    query = >0
    grid = SQLFORM.grid(query,csv=True,paginate=10)
    return dict(grid=grid)


{{extend 'layout.html'}}
if not request.args:

 w2p_grid_tbl = grid.element('table')
 if w2p_grid_tbl:
 original_export_menu = grid.element('div.w2p_export_menu')
 export_menu_links = original_export_menu.elements('a')
 export_menu_items = []
 for link in export_menu_links:
 item = LI(link)
 new_export_menu = DIV(
                      A( T('Exports'),
                         _class='btn dropdown-toggle',
                    _class='w2p_export_menu btn-group'
 export_menu = grid.element('div.w2p_export_menu',replace=new_export_menu)

How to use gmaps.js on web2py

It's easy to handle Google Maps on your website and of course it will be much easier if you use web2py!

1. Create new app called gmap

2. Download gmaps.js
Go to and download gmaps.js. Place it under the app folder static/js/gmaps.js

3. controllers/
Replace the def index() with the following.

def index():
    from import geocode
    latitude = longtitude = ''
    form=SQLFORM.factory(Field('search'), _class='form-search')['_class'] = 'input-long search-query'
    form.custom.submit['_value'] = 'Search'
    form.custom.submit['_class'] = 'btn'
    if form.accepts(request):
        (latitude, longitude) = geocode(address)
        (latitude, longitude) = ('','')
    return dict(form=form, latitude=latitude, longitude=longitude)
Note:  There was an issue #855 and just fixed with the Version 2.0.0 (2012-06-17 23:36:32) dev. If you are using the web2py version older than this, make sure to replace the latitude and longitude as follows.
 (longitude, latitude) = geocode(address)
4. views/default/index.html
Replace it with the following.

{{extend 'layout.html'}}
<script src=""></script>
<script src="{{=URL('static','js/gmaps.js')}}"></script>
{{if longitude or latitude:}}
<p>latitude, longtitude: {{=latitude}},{{=longitude}}</p>
<div id="map" style="height:400px;width:800px"></div>
  map = new GMaps({
    div: '#map',
    lat: {{=latitude}},
    lng: {{=longitude}}
    lat: {{=latitude}},
    lng: {{=longitude}},
    title: 'Here!',
    infoWindow: {
        content: '<p>{{}}</p>'
5. Result
Type "243 S Wabash Ave, Chicago, IL, USA" and see the result.

web2py on PythonAnywhere

It's too bad fluxflex will shut down and will be no longer available on June 30, 2012. It was great service, easy to deploy, I was a little bit frustrated with using git but overall I enjoyed. Especially, I was one of the fun because this company was established by young Japanese guys !

I was looking for new place and introduced PythonAnywhere in the web2py forum.

It's so easy to install. All you have to do is sign up for free account, click web2py icon and Done !
I was running my test app in a few minutes.

Wow! I'm very impressed!!

Maybe I can spend $9 per month to host it under own domain name. The performance should be enough  for the small app !

I'm not familiar with console (I'm windows guy) so I wonder how I can update wen2py when new version is available...
