如何处理Django API框架POST的外键和多个错误？

from django import forms
from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
from .models import ParentModel, ChildModel

class MyForm(forms.ModelForm):
    class Meta:
        model = ParentModel
        fields = ['name', 'child']

@csrf_exempt
def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            parent = form.save()
            return JsonResponse({'success': True, 'parent_id': parent.id})
        else:
            errors = form.errors.as_json()
            return JsonResponse({'success': False, 'errors': errors})
