Hi,
i thought this place best to ask this question as i'm developing my
very first apps with TurboGears. I come from php background and couple
of months ago i wanted to expand my programming language skills. I met
and liked python because of its simple and elegant syntax. On php land
there are a plethora of web frameworks which is cool and not so cool
at the same. Almost everytime i have found myself developing my own
framework for the specific app.
With python its another thing. Since i dont have experience with that
language, im not interested to create own framework. There seems to be
just few web frameworks available so i have constructed tutorial app
with Django, Pylons and TurboGears. At this moment i dont know which
one to decide (or should i combine them somehow) and i need still more
exercise apps created.
Ok, lets that be the forewords and going to the subject and question
itself.
I want to create method to retrieve and save user settings depending
on which storage or placeholder is available at the moment. On my app,
user can be guest or member type (including all the different members
as regular member, admin, moderator, superuser etc.). Now if user is
guest there are three levels of settings inheritance:
+ Application
+ Cookie
+ Session
(+ POST)
with member there is one more level between application and cookie:
+ Application
+ Data (-base or file)
+ Cookie
+ Session
(+ POST)
Now if i want to retrieve variable for member i make a call:
get_user_variable('variable_name') and it seeks through all the
levels. Upper level overriders lower levels variables so first i get
an initial value from Application, then seeking data layer, again
cookie layer and finally session layer.
When updating values i get data from POST request and move it down to
data layer if user is member and to cookie (if available) or session
layer if user is guest.
Now id like to hear comments how such a thing should be implemented
with python and expecially with TurboGears as i need hand to hand
examples and advices at this moment. Thanks in advance.
