The same controller method for ajax and nonajax call

[Alex]

Hello,

I have "get_workout" action in controler and this action could be
called either directly using GET method, or could be called using
AJAX.

If it's called using GET it should return (render) whole page.
If it's called using AJAX it should return (render) only a part of the
page

It's not clear how to do it using web2py

I wanted to check inside controller method if current request it GET /
POST or AJAX and then change the logic of the method but didn't find a
way to check if current request is AJAX, how to do it?

I use such kind of link:
<a href="{{=URL('gym','default','get_workout')}}" onclick="ajax('{{=URL
(r=request,f='get_workout')}}', [], 'fitness_goals');return false;">
{{=a.title}}</a>

The base idea is to make partial page update using AJAX with loading
banner displaying during update and page opening using non-AJAX
request when whole page HTML will be loaded.

What is the best way to do it?

Thanks.

On your ajax calls use the .json

so

http://mysite.com/init/default/index/ for normal pages

http://mysite.com/init/default/index.json/ to get the dict converted to json

or

index.xml to get it in xml format..

But how can controller method know if current request is POST / GET or
AJAX?

Sometimes it's needed to generate very different part of HTML page and
return it to update some DIV on the page.

Send a var back with the ajax request:

<a href="{{=URL('gym','default','get_workout')}}" onclick="ajax
('{{=URL

(r=request,f='get_workout',vars=dict(is_ajax=True))}}', [],

'fitness_goals');return false;">
{{=a.title}}</a>

if request.vars.is_ajax:
....

Could work, but is not what I expected too.

Actually I found solution, if anyone will be intersted in it:

request.env.http_x_requested_with
could be str('XMLHttpRequest') on ajax request

request.env.request_method
is str('POST') or 'GET'

And this what I needed :)
