Calling taskqueue from multiple places on Google App Engine

Question

I'm trying to using taskqueues in Google App Engine. I have something like

class TrackBuildHandler(webapp.RequestHandler):
    def post(self):
        track_name = self.request.get('track_name')
        taskqueue.add(url='/runbuild/track', params={'track_name': track_name})

class TrackBuildWorker(webapp.RequestHandler):
    def post(self):
        ...


class SomeClass(webapp.RequestHandler):
    def post(self):
        ...
        taskqueue.add(url='/runbuild/track', params={'track_name': track_name})

From what I gather you can't call this command from two different places in your code because if I remove the TrackBuildHandler class the call from SomeClass works but otherwise only TrackBuildHandler works. How would I go about posting data to TrackBuildHandler from SomeClass or is there a better way to do this? Thanks.

EDIT: I should note that the url '/runbuild/track' is routed to TrackBuildWorker.
