I am seeing some behavior with session that I don't understand. If I
have a session variable called recentAddIds that contains a list. I
find that if I append to that list, like this:
request.session['recentAddIds'].append(newlySavedId)
Then when I next receive a GET, I find that request.session
['recentAddIds'] does not contain the appended data (but does contain
the data that was there prior to the append).
If I instead make a copy of the list and put that copy into the
session variable, then when I next receive a GET, my session variable
does not contain the newly appended data.
request.session['recentAddIds'] = [x for x in request.session
['recentAddIds']] + [newlySavedId]
Can anyone explain why this is and if it is expected behavior? Is it
ok for sesion variables to contain lists or other complex structures,
or should they just be simple strings?
