Django 4.1: implementing Admin Inline Forms Not Saving Related Model Data
Hey everyone, I'm running into an issue that's driving me crazy. I'm trying to figure out I tried several approaches but none seem to work. I'm working with an scenario with Django 4.1 where the admin inline forms for a related model are not saving correctly. I have a `Book` model that has a one-to-many relationship with an `Author` model, and I've set up the inline model admin for `Author` within the `BookAdmin` class. However, when I try to add or update an author through the admin interface, the related `Author` instance is not being saved to the database. Hereโs how my models and admin configuration look: ```python # models.py class Author(models.Model): name = models.CharField(max_length=100) book = models.ForeignKey('Book', related_name='authors', on_delete=models.CASCADE) class Book(models.Model): title = models.CharField(max_length=200) ``` ```python # admin.py from django.contrib import admin from .models import Book, Author class AuthorInline(admin.TabularInline): model = Author extra = 1 class BookAdmin(admin.ModelAdmin): inlines = [AuthorInline] admin.site.register(Book, BookAdmin) ``` When I submit the form after adding an author, I receive no behavior messages, but the `Author` instance does not appear in the `Book`'s related authors list. Iโve verified that the `Book` instance itself is being saved correctly before the inline form processing. I also tried overriding the `save_related` method in `BookAdmin` to see if I could debug the save process, but it didn't help. Hereโs the code I tried: ```python def save_related(self, request, form, formsets, change): super().save_related(request, form, formsets, change) # Debugging: Check authors saved authors = formsets[0].instance.authors.all() print(authors) # This is showing an empty QuerySet ``` I've checked that the `Book` instance is correctly linked to the `Author` model via the foreign key, but it seems like the inline isnโt capturing the data. Has anyone else faced this scenario or know what might be going wrong here? Any ideas what could be causing this? Any feedback is welcome! I appreciate any insights!
