Thanks Tom, now I see your point.
As my API was crafted on the previous version of Datatables, and used only
for that purpose, I prefer just to replace it with the new one.
Had I already an API for whatever reason, I see the usefulness and the
importance of your approach. I understand the logic, but I'm still not sure
how I could code it.
The QueryDict you point out is in my case `request.GET`.
new_request_get = QueryDict(mutable=True)
new_request_get['new_key'] = request.GET['old_key']
# ...
# Set perhaps mutable=False
form = DataTablesForm(new_request_get)
Is what you mean something like that?
Thanks,
Andrea
