How to filter empty or null Names in a Python django QuerySet?

Estimated read time 1 min read

To filter out empty or null names in a Django QuerySet, you can use the __isnull and __exact lookup filters provided by Django’s ORM. Here’s an example of how you can accomplish this:

from django.db.models import Q

# Assuming you have a model called 'Person' with a 'name' field
# and you want to filter out empty or null names
filtered_persons = Person.objects.filter(Q(name__isnull=False) & ~Q(name__exact=''))

# The resulting QuerySet will only contain persons with non-empty and non-null names

In the example above, we use the Q object from Django’s models module to create complex queries. The Q(name__isnull=False) filter ensures that the name field is not null, and the ~Q(name__exact='') filter excludes names that are empty.

The filter() method is used on the Person model to apply the filters. The resulting QuerySet, filtered_persons, will only contain instances where the name field is non-empty and non-null.

You can further chain additional filters or perform other operations on the filtered_persons QuerySet as needed.
