User_agent in a LOADed view

[Louis Amon]

I'm a great fan of LOAD, and i'm using it quite a bit to generate cool ajax pages.

I got one issue so far though : can't seem to cleanly detect a mobile device in a .load view.

For example I have a "result.load" view and I want a special mobile display in "result.mobile.load".

I've tried to use the decorator @mobilize but it seems that user_agent() raises an Exception when called from a LOADed view.

Is there a clean way to do that ?

For those who, like me, are struggling over this, there is a monkeypatch :

In the controller/view that calls LOAD(...):

LOAD(..., vars=dict(is_mobile=request.user_agent().is_mobile))

In the LOADed view:

is_mobile = (request.vars.is_mobile == 'True')

Please show your code and the exception.

Sure. It's fairly simple tho since the Exception gets raised on line 1 of my LOADed view.

Views/default/search.html:

...
{{ =LOAD('service', 'serv1') }}
...

Controllers/service.py:

response.view = "service.load"

def serv1():  
    return dict()

Views/service.load :

{{ is_mobile = request.user_agent().is_mobile }}
...

Note, you are using a non-Ajax component. I'm not sure why request.user_agent isn't defined in that case, but there are some funky things going on with non-Ajax components, so I would instead recommend using Ajax components:

{{=LOAD('service', 'serv1', ajax=True)}}

Feel free to file a Google Code issue about user_agent not work with non-Ajax components.
