Hi David-
Yes, I'm using GAE's taskqueue with web2py, and it works in both the
dev and production environments. Note that in the dev environment, the
tasks do not run automatically - you will need to manually trigger
them using the http://localhost:8080/_ah/admin web console.
I wasn't able to get the url-encoded payload variable working
properly, so I tried the other method that uses a params dictionary
and it worked OK. (I'm not a python expert, so it's quite likely that
I was doing something wrong with urllib.) In any case, here is the
code snippet that works for me to create a task:
if request.env.web2py_runtime_gae: # if running on Google App Engine
from google.appengine.api.labs import taskqueue
tqparams = {'row_id':r}
taskqueue.add(
url=URL(r=request, c='mycontroller', f='call/run/taskfunction'),
params=tqparams,
)
and the controller file that gets called has these lines in it
(simplified for this example):
def call():
return service()
@service.run ## we'll use this to enable this as a taskqueue-
friendly URL
def taskfunction():
"""
For security, this URL should be restricted to the admin user in
app.yaml
"""
return dict(row_id=request.vars.row_id)
