Hi everyone,
I'm beginning to use web.py framework which is a little bit tricky when it
comes to play with session.
First, the official documentation <http://webpy.org/cookbook/sessions> is
clearly outdated when talking about session. (I made a pull request to
update the "counter" example).
The counter is easy as i manipulate a primitive type.
But when i want to store an object into session i'm stuck. It seems that
each call to different function manipulate a different instance.
So i wanted to know if a session can store object ?
My objective is to share the same object "foo" between function calls.
For more clarity here the code i use:
import web
import shelve
from Elevator import elevator
urls = (
'/call', 'call',
'/go', 'go',
'/userHasEntered', 'userHasEntered',
'/userHasExited', 'userHasExited',
'/reset', 'reset',
'/nextCommand', 'nextCommand',
)
sessionObject = shelve.open('session')
shelfStore = web.session.ShelfStore(sessionObject)
app = web.application(urls, globals())
class call:
def GET(self):
session = web.session.Session(app, shelfStore)
atFloor = web.input().get('atFloor')
print atFloor
try:
elevator = session.store.shelf["elevator"]
except Exception:
session.store.shelf["elevator"] = elevator()
elevator = session.store.shelf["elevator"]
print "First elevator instance: ", elevator
elevator.call(atFloor)
return web.http.web.OK
class go:
def GET(self):
session = web.session.Session(app, shelfStore)
elevator = session.store.shelf["elevator"]
elevator.go()
return web.http.web.OK
class userHasEntered:
def GET(self):
session = web.session.Session(app, shelfStore)
elevator = session.store.shelf["elevator"]
elevator.userHasEntered()
return web.http.web.OK
class userHasExited:
def GET(self):
session = web.session.Session(app, shelfStore)
elevator = session.store.shelf["elevator"]
elevator.userHasExited()
return web.http.web.OK
class nextCommand:
def GET(self):
session = web.session.Session(app, shelfStore)
elevator = session.store.shelf["elevator"]
print "second elevator instance: ", elevator
return elevator.getNextMove()
class reset:
def GET(self):
print "reset"
return web.http.web.OK
if __name__ == "__main__":
app.run()
What is the purpose of the elevator? Doesn't matter. My problem is that i
can't share the same elevator instance between each methods (call, go, ...)
Thx for your answers.
