Django - Unexpected Behavior with QuerySet Caching When Filtering on Related Fields
I've spent hours debugging this and I'm following best practices but I'm working on a project and hit a roadblock... I'm encountering an unexpected behavior in Django 3.2 when filtering a queryset based on related fields. I have two models: `Author` and `Book`, where `Book` has a foreign key to `Author`. When I try to filter books by a specific author's name, I expect to get a fresh queryset, but it seems to be caching the results. Here's the relevant code snippet: ```python class Author(models.Model): name = models.CharField(max_length=100) class Book(models.Model): title = models.CharField(max_length=200) author = models.ForeignKey(Author, on_delete=models.CASCADE) # Fetching books by a specific author author = Author.objects.get(name='John Doe') books = Book.objects.filter(author=author) # This works as expected for book in books: print(book.title) # Later in the code, trying to filter again books = Book.objects.filter(author=author) ``` After filtering the books a second time, I noticed that if I add or remove books associated with `John Doe`, the queryset does not reflect these changes unless I call `books = list(Book.objects.filter(author=author))`. I also tried using `QuerySet.refresh_from_db()` but it didn’t have any effect in my case. Is there something I’m missing about how Django handles queryset caching, or is there a more appropriate way to ensure I get the latest results? I want to avoid converting the queryset to a list if possible, as it defeats the purpose of using dynamic querysets. Any insights would be greatly appreciated! How would you solve this? The project is a web app built with Python. I'd really appreciate any guidance on this.
