Django/Wagtail Type error 'ModelBase' object is not iterable

I have a project with wagtail. I have created a custom model Admin named sorting. I want to show this model's data in API.

Here is the view in the database

database output

Here is

from django.db import models
from wagtail.models import Page, Orderable

    Featured1 = 0, _('Featured1')
    Featured2 = 1, _('Featured2')
    Featured3 = 2, _('Featured3')
    Featured4 = 3, _('Featured4')
    Featured5 = 4, _('Featured5')

class Featured(ClusterableModel):
    featured_name = models.IntegerField(default=IDChoice.Featured1,choices=IDChoice.choices, blank=True, null=False, help_text='Featured ID', unique=True)
    panels = [
        InlinePanel('featured_pages', label="Featured pages"),

class FeaturedPages(Orderable, models.Model):
    Orderable helper class, and what amounts to a ForeignKey link
    to the model we want to add featured pages to (Featured)

    featured_page = models.ForeignKey(

    featured_item = ParentalKey(

    panels = [
    def __str__(self):
        """String repr of this class."""
        return self.featured_page

    class Meta:  # noqa
        verbose_name = "Featured"
        verbose_name_plural = "Featured Stories"

    add_to_settings_menu = False
    exclude_from_explorer = False
    list_display = ("featured_name","featured_pages")
    search_field = ("featured_name","featured_pages")

class FeaturedList(APIView):

    def get(self, request):
        featured =FeaturedPages.objects.all()
        serializer= FeaturedSerializer(FeaturedPages, many = True)
        return Response(

from rest_framework import serializers
from .models import Featured

class FeaturedSerializer(serializers.ModelSerializer):
    class Meta:
        model = Featured
        fields = "__all__" #("featured_name","featured_pages")

from rest_framework.urlpatterns import format_suffix_patterns
from sorting import views
urlpatterns = [
    path("api/sorting/", views.FeaturedList.as_view()),

The error I am getting while I am fetching the URL

TypeError at /api/sorting/ 'ModelBase' object is not iterable Request Method:   GET Request URL: Django Version:  4.0.6 Exception Type:   TypeError Exception Value:   'ModelBase' object is not iterable Exception Location: C:\Users\Fathi\Envs\mgolpoenv\lib\site-packages\rest_framework\, line 686, in to_representation Python Executable:    C:\Users\Fathi\Envs\mgolpoenv\Scripts\python.exe Python Version:    3.10.5

What am I missing? And How I can show those fields in API?
