Django queryset returning empty when filtering by related model field
I tried several approaches but none seem to work. I'm wondering if anyone has experience with Does anyone know how to This might be a silly question, but I'm working with an scenario where my Django queryset is returning an empty list when I try to filter based on a related model's field... I have two models: `Author` and `Book`, where each book is linked to an author. Here's a simplified version of my models: ```python from django.db import models class Author(models.Model): name = models.CharField(max_length=100) class Book(models.Model): title = models.CharField(max_length=100) author = models.ForeignKey(Author, on_delete=models.CASCADE) ``` I want to retrieve all books by a specific author, for instance, the author with the name 'John Doe'. I tried the following query: ```python books = Book.objects.filter(author__name='John Doe') ``` However, `books` is coming back as an empty queryset, and there are definitely books in the database associated with 'John Doe'. I've checked the database, and the author is present. I also tried: ```python author = Author.objects.get(name='John Doe') books = Book.objects.filter(author=author) ``` This still results in an empty queryset. I even tried creating a few books in the Django admin interface directly to ensure that they were correctly linked to the author. I can see them in the admin interface, but they just won't show up in my queryset. Is there a possibility that this could be related to how the database handles string comparisons, or could there be any potential issues with how the data was migrated? I'm using Django 4.1 with SQLite. Any thoughts on what might be going wrong here? My development environment is macOS. What am I doing wrong? I'm using Python stable in this project. Any examples would be super helpful. This is my first time working with Python latest. My development environment is Debian.
