Django. Admin Tabular Inline. Get parent object

admin.py

class ProductVariantAdminInline(admin.TabularInline):
    extra = 0
    model = ProductVariant
    
    def get_parent_object_from_request(self, request):
        """
        Returns the parent object from the request or None.
    
        Note that this only works for Inlines, because the `parent_model`
        is not available in the regular admin.ModelAdmin as an attribute.
        """
        resolved = resolve(request.path_info)
        if resolved.args:
            return self.parent_model.objects.get(pk=resolved.args[0])
        return None

This did't work for me, I had to change it to the following:

def get_parent_object_from_request(self, request):
        """
        Returns the parent object from the request or None.

        Note that this only works for Inlines, because the `parent_model`
        is not available in the regular admin.ModelAdmin as an attribute.
        """
        resolved = resolve(request.path_info)
        if resolved.kwargs:
            return self.parent_model.objects.get(pk=resolved.kwargs["object_id"])
        return None

        return None

This resolved the issue that's bugging me for hours. Thanks! 🍻
