Hi all, I hope someone can help me.
I've written a nifty application using Pylons with Genshi and Elixir.
But I'm having one crucial problem -- I seem to keep getting stale
data returned from my application. I can sit on a page on my
development system, where I know that nobody else is changing the
data, and if I hit "refresh" several times, I will see different
results. It looks like it's cycling through the data as it was in
various states a few moments ago.
this is what I have in my lib/base.py controller:
from trackmgr.model import Session
class BaseController(WSGIController):
def __call__(self, environ, start_response):
try:
response.headers['Pragma'] = "no-cache"
response.headers['Cache-Control'] = 'no-store;no-
cache;must-revalidate;max-age=0'
Session.clear()
return WSGIController.__call__(self, environ,
start_response)
finally:
Session.remove()
And I've also told Firefox not to cache anything, so I'm pretty sure
that I'm not cacheing on the front end. (If I was, I would not expect
the values to look like they are cycling.)
Oh, and here's the relevant part of trackmgr.model.__init__:
import elixir as e
Session = scoped_session(sessionmaker(autoflush=True,
transactional=True))
e.session = Session
e.options_defaults.update({
"shortnames" : True
})
Is there something obvious that I'm doing wrong?
