[web2py] How to customize widgets to act like Onsen UI components

[Bernardo Leon]

I have been researching about UI Frameworks and stumbled upon Onsen UI 
. It seems easy and provides good results but to use 
this UI Framework I need to use their components which are html tags.

If I have a field that is rendered as an html input how can I customize its 
widget so I can use  instead of  and so on? Thank you!

The following seems to work, by the way (modified from 
https://groups.google.com/forum/#!topic/web2py/TZsLnytjqhA)

## allow mysql tinyint
from gluon.dal import SQLCustomType
boolean = SQLCustomType(
 type ='boolean',
 native='TINYINT(1)',
 encoder = (lambda x: 1 if x else 0),
 decoder = (lambda x: True if x else False)
)

then

Field('xxx', type = boolean,...)

[web2py] Re: Stopping a loaded component

[Francisco Ribeiro]

Found a solution for this which is to add the 'w2p_component_stop' class 
onto the div, as follows:

  $('#my_target').addClass('w2p_component_stop');
  $('#my_target').html(''); 

this will break the infinite loop set by the call in my original post and 
then will hide the content left from the last iteration of the loop.

By the way, starting web2py using Rocket now says

[web2py] Re: Storing stuff on request object

[Anthony]

It should be OK. The only potential issue is if the framework adds 
request.some_stuff in the future -- then your app code would be overwriting 
an attribute used by the framework (unlikely to be an issue if you avoid 
generic names).

Forgot about that. It's documented here:

Yes, that would be the way to go if you want to move the function to a 
module.

Hard to say what's going wrong without seeing your code. But you don't 
necessarily have to put the function in a module -- it can go in a model or 
even in the controller (if the function takes no arguments, start its name 
with a double underscore to prevent it from being exposed as an action). 
You can even define the function inside the controller function that calls 
it if that's the only place it is needed.

[Anthony]

See

In routes.py, something like:

routers = dict(
BASE = dict(
default_application='init',
default_controller='default',
default_function='index'
),
init = dict(
functions=['list', 'of', 'functions', 'in', 'default', 'controller']
),

[web2py] Re: caching variable data sample

the more digging the deeper one gets :

https://groups.google.com/forum/?fromgroups#!searchin/web2py/cache$20in$20module/web2py/AZa5Boj3y3E/_BPMTdXwSaMJ

and here is the *cache_this*  module version :

from gluon.cache import lazy_cache

@lazy_cache('data_sample', time_expire=60, cache_model='redis')
def cache_this():
...
rows = db(db.atable.id > 0).select(limitby=limitby, cacheable=True)
return rows


This seems to do the trick.  Is it 'kosher' ?

actually the real function is a little more complex since it returns rows 
plus other datas that don't require caching. I tried to move the cache_this 
function to a module (don't know if this is orthodox) but then i get a 
decorator error:

@current.cache('data_sample', time_expire=60,

[web2py] How to get rid if the /init/default/ in the URL?

[Joe]

I've been trying to do this for so long, but with *pythonanywhere* hosting, 
it doesn't seem to be possible to get rid of the *init/default/* part of 
the URL.

I think, this nested sub-directories structure is not optimal for SEO and 
also makes it difficult to place the *robot,txt* and *sitmap.xml* in a way 
that it's easy to find for search engines?
I am not a SEO expert, but I read that this kind of URL structure is not 
optimal.

When I looked at the Web2py website, *which I think is also hosted by 
pythonanywhere*, I noticed that, www.web2py.com has not solved this problem 
either i.e. http://www.web2py.com/init/default/support

Is there any way to change this URL structure?
