Bokeh, Ajax, and Django

Hi,

I am wondering if there is a working example similar to this one but for Django:

In particular, I have problems to implement the (apparently needed) crossdomain feature.

Thanks

Cross domain is
usuall y a case of configuring your
django pro cess correctly to
accept requests from where ver
your bokeh request is coming from.

Thanks Sarah for the hint.
Indeed there is middleware for Django to deal with crossdomain (e.g. see answer here http://stackoverflow.com/questions/20354135/django-view-with-cross-domain-ajax).
But I found a much simpler way that works for my use case:

source = AjaxDataSource(method=‘GET’,data_url=‘http://localhost:8000/view2d/data/’,
polling_interval=1000)
…
def data(request):
response = JsonResponse(dict(x=[10],y=[10]))
response[“Access-Control-Allow-Origin”] = “*”
response[“Access-Control-Allow-Methods”] = “GET, POST, OPTIONS”
response[“Access-Control-Max-Age”] = “1000”
response[“Access-Control-Allow-Headers”] = “Content-Type”
return response

Yay!
