How can I do it? I mean sometimes if there I fill the form again for
same job no. It accepts the value on submitting. Why it is not giving
me an error at that time that it the data for this entry already
exists. Is it the case of not using primary key. I mean is it
necessary to use primary key in all the tables. Or if we are using the
auto_increment id as primary key, can we so it.

So You need to add a unique constraint to your model definition. See https://docs.djangoproject.com/en/1.6/ref/models/fields/#unique .
 

How can we expire a
session if we so refreshing of page and resubmitting it?. What is the
best way to do coding in django? How can we maintain an erp based
website in django? How can we improve the database of django app. How
can we understand all the logics of django? Which type of applications
we can make in django? How can we do less code? How can we best learn
django with proper coding standards? How?

All these questions are best answered with a separate thread for each.
