django-orm case-insensitive order by

Question

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__contain         


        

Answer 1

This is for postgresql, but maybe it will be useful for other databases too:

Answer 2

This answer is outdated, check below solution with django 1.8 ->

I found solution using .extra

class MyModelName(models.Model):
   is_mine = models.BooleanField(default=False)
   name = models.CharField(max_length=100)


MyModelName.objects.filter( is_mine=1 ).extra(\
    select={'lower_name':'lower(name)'}).order_by('lower_name')

Answer 3

Since Django 1.8 it is possible with:

from django.db.models.functions import Lower
MyModel.objects.order_by(Lower('myfield'))
