this is a demo about integrating django signals to django projects
lets say we have to perform a task upon creation of a database entry so we may create respective view BUT
BUT.. what if we added something from admin panel, normal view functionality wont work in that case.
django signals prove apt in this case!
A signal is an object corresponding to particular event.
is something which triggers signals
are the handler functions which have to execute as a consequence
one is using signal.connect()function
second is using @ receiver decorator
