So you want to keep track of the number of a times a user (in a user's
session) clicked on the images 1 to 3. Using a session to capture this
count, you won't be able to track the total number of clicks across all
users (just saying)
My understanding is:
* the url comes in as 'show/some_number'
* you use the the 'some_number' to query the database for a matching
'image'.
The changes you would need to make are:
if image.id == 1:
session.one_counter = (session.one_counter or 0) + 1
if image.id == 2:
...

Hi Kiran,
Thanks very much for your reply.
I tried to initialize session.one_counter/two_counter/three_counter
but it seems my understanding of the session variables in this case is
not sufficient to get this right.
Basically, I am stuck with this one.
My aim is to count the clicks to image.id *1*, image.id *2* and
image.id *3* separately, so I can compare them.
If you could guide me in the right direction so I can have a better
understanding and solve this problem or if you could correct my code,
I would really appreciate it.
Thanks again.
Cheers,
Joe

You seem to be incrementing 'counter' in the session (the counter
is user session specific then).
Also, you are using session.one_counter/two_counter/three_counter,
without having initialized it. Is that a typo?

I am trying to use session.counter to count clicks on images on a
page.
My problem is that my session.counter is not counting...
I am doing something wrong, not sure exactly what.
I am pretty sure the issue is the/if image.id <http://image.id> == 1/
I'd appreciate some help with this.
*Controller:*
def index():
images = db().select(db.image.ALL, orderby=db.image.id
<http://db.image.id>)
return dict(images=images)
def show():
image = db.image(request.args(0,cast=int)) or
redirect(URL('index'))
one_counter = []
two_counter = []
three_counter = []
if image.id <http://image.id> == 1:
session.counter = (session.counter or 0)+1
one_counter=session.one_counter
elif image.id <http://image.id> == 2:
session.counter = (session.counter or 0)+1
two_counter=session.two_counter
elif image.id <http://image.id> == 3:
session.counter = (session.counter or 0)+1
three_counter=session.three_counter
return dict(image=image)
def download():
return response.download(request, db)
*View:*
show:
<h3>{{=0 if session.one_counter is None else
session.one_counter}}</h3>
<h3>{{=0 if session.two_counter is None else
session.two_counter}}</h3>
<h3>{{=0 if session.three_counter is None else
session.three_counter}}</h3>
