如何在django中显示继承模型的字段？

from django.db import models

class ParentModel(models.Model):
    shared_field = models.CharField(max_length=100)
    # 其他共享字段

class ChildModel(ParentModel):
    extra_field = models.CharField(max_length=100)
    # 其他子模型特有字段

from django.shortcuts import render
from .models import ChildModel

def my_view(request):
    child_objects = ChildModel.objects.all()
    return render(request, 'my_template.html', {'child_objects': child_objects})

<!-- my_template.html -->
{% for child_object in child_objects %}
    <p>Shared Field: {{ child_object.shared_field }}</p>
    <p>Extra Field: {{ child_object.extra_field }}</p>
{% endfor %}
