Re: dev server not loading localhost urls

[adelevie]

Thank you for explaining that the ports were the issue. My little
workaround is to simply run two dev servers:
from command line: python manage.py runserver 8080
then open another command line window: python manage.py runserver 8000

So in my views, the url I access is on port 8080. So when I access my
api through a browser, I use localhost:8000.

you are trying to get the results of another request from the same
development server?  Yes, this will hang.  The development server is
single-threaded.  So, if you send off a 2nd request while processing a
request, the single thread of the dev server blocks waiting for the response
to the 2nd request.  Meanwhile the 2nd request is queued up waiting for
processing of the 1st request to complete

dev server not loading localhost urls

[adelevie]

I am making an api. Part of the api involved serializing data which
will then be deserialized on another machine. Since I am using the dev
server, I wrote a view that referenced the api, ie:

def someview(request):
 data = urllib2.urlopen("http://localhost:8080/some_method/?
param=foo")
 output = []
 for obj in serializers.deserialize("xml", response):
  output.append(obj)
 return HttpResponse("%s" % output[0].some_model_attr)

When I go to localhost:8080/someview, the page loads indefinitely with
no data brought to the screen. (and my urlconf is correct ;) )
