Hi Elvelind,
I'm trying to get something in this line working in a project but can't
seem to get it right:
@turbogears.expose("webpanel.templates.list")
@turbogears.expose("json")
def index(self, origin=None, destination=None):
format = cherrypy.request.params.get("tg_format", "default")
print "%s,%s,%s" % (origin, destination, format)
if format == "json":
return dict(message="returning json")
else:
return dict(
list_widget=self.list_widget,
data=self.sql_class.select(user_items(self.sql_class)),
)
When I pass tg_format=json as a GET param I get (sic):
Page handler: <bound method AliasController.index of
<webpanel.mailbox.controllers.AliasController object at 0x20f5490>>
Traceback (most recent call last):

None, False, (<webpanel.mailbox.controllers.AliasController object at
0x20f5490>,), {'origin': None, 'tg_format': 'json', 'destination':
None}), {})
And when no tg_format param is passed a jsonify exception is raised
which means that expose is treating it as if tg_format was json (and
trying to jsonfiy the grid widget).
Am I missing something?
I'll explain what I'm trying to accomplish in case there's a better way
to do it: I want to display a fastdata grid on default format and feed
JSON data into a AjaxDataGrid on "tg_format=json".
Unfortunately, they expect data in slightly different formats so I need
to branch depending on tg_format to feed them them correct dict.
As a suggestion, a 'branch_to' (or better name) optional arg that
branched to another method ( a là error_handler) will be very nice to
support this kind of behavior without the ugly lookup at request.params
Thanks for any help,
Alberto
