Okay... I installed your version and took a look at what was going
on.
I am a little confused about a couple of things:
In the controller:
@auth.requires_login()
def toggle_attendance():
"""
This is where a user can toggle attendance to
any event displayed on the 'tonight. page.
"""
event_id = request.args(0)
if db((db.attendance.event==event_id) &
(db.attendance.user==auth.user.id)).delete():
return 'You are attending this event'
else:
db.attendance.insert(event=event_id, user=auth.user.id)
return 'You are not attending this event'
This obviously works but looks backwards to me for some reason. What
am I missing?
In the view:
<button id="x{{=item.event.id}}"onclick="ajax(
'{{=URL(r=request,f='toggle_attendance',
args=item.event.id)}}',[],'x{{=item.event.id}}');">
Can you step me through what is going on here. I'm not sure I
understand how the helpers work with ajax. I get that you are
creating a 'button' and that it is passing the event.id to the toggle
function. I guess my confusion is still the confusion about how the
toggle is deciding what to return. It seems like if it successfully
deletes the attendance record, it returns that there IS an attendance,
and if it inserts an attendance record it returns that is NOT an
attendance. This is not what actually happens so why am I reading it
this way? I also don't understand where what is actually returned is
represented in the view.
Thanks for your help
