Re: [google-appengine] Sample for Push Queues

[Robert Kluin]

Hi Hariprasath,
If you don't specify an eta or countdown, then the request will be
processed once resources are available to process it.

Tasks are just like any other request, so there really isn't
anything special to show you. Just write a request handler like any
other.

Hi Robert,

                           Thanks for your reply. But i found a strange behaiviour, when i add tasks in the queue with the call below,

                         taskqueue.add(url='/autobot', params={'key':game.userXid}, queue_name='autobot') 

the execution of the task is not happening ASYNCHRONOUSLY. the code waits for the task to be completed by executing the logic which i defined in '/autobot' url and then it  moves ahead with the instructions that follow the taskqueue.add( )  function. Is there anything im doing wrong here?. 

Thanks,

Hariprasath Mohankumar

Hi Hariprasath,
Is this on the dev server or appspot? You probably need to provide
a little more code context as well.

Hi Robert,

                          this is happening in the dev server.  The code is as follows.

class botinitiate(webapp.RequestHandler):

  def get(self):

        # some more statements here

        template_values = {'token': token,

                           'me': user.user_id()

                          }

        taskqueue.add(url='/autobot', params={'key':game_key},queue_name='autobot')    #creating the task and adding it to the queue

        path = os.path.join(os.path.dirname(__file__), 'index.html')

        self.response.out.write(template.render(path, template_values))

class autobot(webapp.RequestHandler):

    def post(self):

                    #      task logic goes here

application = webapp.WSGIApplication([('/botinitiate',botinitiate),('/autobot',autobot)],debug=True)

def main():

  run_wsgi_app(application)

if __name__ == "__main__":

  main()

when i add the task using taskqueue.add() function it adds the task to the queue and it waits for the task to complete and then it executes the following statements after finishing the task. Am i doing anything wrong here? Can you provide me a code sample that does this functionality?
