Nonrelated inlines

Django Unfold provides a powerful feature for displaying inlines that don't have a direct relationship (no foreign key) with the main model in the changeform view. These nonrelated inlines are available through the unfold.contrib.inlines module. To use this functionality, ensure that you have included the module in your project's INSTALLED_APPS configuration within settings.py. This feature allows you to display and manage related data even when there isn't a traditional database relationship between the models.

from django.contrib.auth.models import User
from unfold.admin import ModelAdmin
from unfold.contrib.inlines.admin import NonrelatedTabularInline
from .models import OtherModel

class OtherNonrelatedInline(NonrelatedTabularInline):  # NonrelatedStackedInline is available as well
    model = OtherModel
    fields = ["field1", "field2"]  # Ignore property to display all fields

    def get_form_queryset(self, obj):
        """
        Gets all nonrelated objects needed for inlines. Method must be implemented.
        """
        return self.model.objects.all()

    def save_new_instance(self, parent, instance):
        """
        Extra save method which can for example update inline instances based on current
        main model object. Method must be implemented.
        """
        pass


@admin.register(User)
class UserAdmin(ModelAdmin):
    inlines = [OtherNonrelatedInline]
