Set Time Constraint for generated URL of uploaded files
You can have a datetimefield as an additional column and expire it as and when required.
I am trying to build an application (using Django) which uploads files and generates corresponding URL. Is there some way we can set time constraint for the url, i.e. the uploaded file in url should exist only for little time after the specified time that url should give an error.
I would be using the default django server, in such a case what would be the possible ways to tackle the time constarint problem. I would be glad if you answer for both the cases as for global and individual files, or even a single solution is good :)
