Can I use Django F() objects with string concatenation?

Question

I want to run a django update through the ORM that looks something like this:

MyModel.objects.filter(**kwargs).update(my_field=F(\'my_other_field\')+\'a stri

You can use Concat function https://docs.djangoproject.com/en/1.9/ref/models/database-functions/#concat

from django.db.models.functions import Concat
from django.db.models import Value

MyModel.objects.filter(**kwargs).update(my_field=Concat('my_other_field', Value('a string'))
