 aggregate() - It is a terminal clause for a queryset that, when invoked, return dictionary name-value pair. Required Module: django.db.models import Avg, Min, Max, Sum, Count Open views.py file and write this code e.g. def home(request):               stud_data=Student.objects.all();                average=stud_data.aggregate(average('marks'))               total=stud_data.aggregate(Sum('marks'))               minimum=stud_data.aggregate(Min('marks'))             maximum=stud_data.aggregate(Max('marks'))             totalCount=stud_data.aggregate(Count('marks'))  context { 'students':stud_data,'average':average,'total':total,'minimum':minimum,'maximum':maximum,'totalCount':totalCount }

data= User.objects.all() <Queryset [<User: sandy sandy@gmail.com 123456789>, <User: rakesh rakesh@gmail.com 8888888888>, <User: Prasad prasad@gmail.com 7478747874>]> get() - It returns one single object. If there is no result match it will raise DoesNotExist exception. If more than one item matches the get() query. It will raise MultipleObjects exception. Example - Student.objects.get(pk=1) Here pk is the primary key first() - It returns the first object(row) matched by queryset. or None if there is no matching object. If the queryset has no ordering defined, then query set automatically  order by the primary key. Example - Student.objects.first() last() -  It returns the last object(row) matched by queryset. or None if there is no matching object. If the queryset has no ordering defined, then query set automatically  order by the primary key. Example - Student.objects.last() latest() - It returns the latest object in table based on the giv...
