Re: Timer for online examination

2015-11-17 Thread Jani Tiainen 

Hello,

As I said, on client side doing timer requires javascript usage. But it 
doesn't remove need to actually make sure that no-one can manipulate 
duration of exam.


It's really trivial to have piece of javascript that would render plain 
javascript timer useless (like you could fill out form forever).


So to make sure cheating doesnt happen - at the moment exam is created 
exam end time should be recorderd on server side as well (in database 
for example). So even someone manages to hack the js (which is really 
simple) they can't overcome limitation from the server.


Like the rule #1 in web development says - "Never trust user input".

Hello,
I think you will  have to implement jquery/javascript to make the timer.
After the countdown finishes js can post the form automatically.

Cheers.

Re: Timer for online examination

2015-11-16 Thread Jani Tiainen 

Hi,

If you're looking something magical there isn't anything. Just declare 
expiracy timestamp and compare against it in code. It should be rather 
trivial to do with JS down counter to UI for mode concrete feedback to 
end user.


But keep final word of expiracy in Django code.
