I know, I can run a case insensitive search from DJango ORM. Like,

User.objects.filter(first_name__contains="jake")
User.objects.filter(first_name__contains="sulley")
User.objects.filter(first_name__icontains="Jake")
User.objects.filter(first_name__icontains="Sulley")

And also, I can fetch them as

user_list = User.objects.all().order_by("first_name")
# sequence: (Jake, Sulley, jake, sulley)
user_list = User.objects.all().order_by("-first_name") # for reverse
# sequence: (sulley, jake, Sulley, Jake)

Is there a direct way for a case-insensitive fetch?? As in I want a sequence as

# desired sequence: jake, Jake, sulley, Sulley

If not, then suggest a best way to do it. Thanks in advance.

Lets take an example where you have to do a case insensitive order by of the field "first_name" from the User Model

# Importing the Lower Function
from django.db.models.functions import Lower


#For ordering by Ascending order
User.objects.all().order_by(Lower('first_name'))

#For ordering by Descending order
User.objects.all().order_by(Lower('first_name').desc())

The Lower function converts all the "first_name" values into lowercase, and then it's ordered accordingly.
