Re: Doubt regarding JSON/SQL in Django

Thanks !

Okay, so i am dropping the idea of using JSON for storage.

So, if I use JSON only as a format to send data
to client ( All the parsing will be done client side ), is it better
than using {{ task.name }}, {{ task.start_date }} ? ( Sorry to ask
this again, but i haven't got it )
