django queryset models Python

I am currently working with a question with my Django application where I'm trying to create a custom QuerySet using a custom Manager, but it returns empty results even though there are records that should match the filter criteria. My models look like this: ```python from django.db import models class MyModelManager(models.Manager): def active(self): return self.filter(is_active=True) class MyModel(models.Model): name = models.CharField(max_length=100) is_active = models.BooleanField(default=True) objects = MyModelManager() ``` In my views, I am trying to call the `active` method like this: ```python from .models import MyModel def my_view(request): active_items = MyModel.objects.active() print(active_items) ``` When I run this code, I expected `active_items` to return all instances of `MyModel` where `is_active` is `True`, but it returns an empty queryset instead. I have double-checked the database and confirmed that there are indeed entries with `is_active` set to `True`. I also tried querying directly using: ```python MyModel.objects.filter(is_active=True) ``` and it also returns an empty queryset. I have made sure that my database is migrated, and I can see the records in the admin interface. I'm using Django 4.0 and PostgreSQL as my database. Could this be a result of the database connection settings or perhaps a caching scenario? Any insights would be greatly appreciated!
