sorry kenneth ...but I have stored information(resume) of professors in the database. in models.py , i have taken fields like name, dob, qualification,designation etc. then these are saved in the database of every professor. but the point is designation of professors vary(like there are professors, assistant professors and associate professors).I want that it should count the no of professors, assistant professors and associate professors automatically and increments their value after I fill and save the next resume in the database. Is there any logic like this...plz help me. I shall be very thankfull.
