models grouping by date and count data

views.py

# simple snippet data to grouping and counting a django models
# for example in this data
# I have fields with attribute DateTimeField 
# so I use `Model.objects.datetimes`
# Because I just want get day,month,year
# If you just use fields `DateTime` Prefer you can use  `Model.objects.date`

users = Model.objects.all() # Models to be grouping
count_user = [{'val': users.filter(date_joined__day=x.day,date_joined__month=x.month,date_joined__year=x.year).count(), 'date':x.strftime('%Y-%m-%d')} for x in Model.objects.datetimes('date_joined','day')]
