在django中使用基于类的视图如何将数据插入到连接表

from django.views.generic import View
from .models import ModelA, ModelB

class MyView(View):
    def post(self, request):
        # 获取要插入的数据
        data = request.POST.get('data')

        # 创建一个新的ModelA对象
        model_a = ModelA.objects.create(data=data)

        # 获取要连接的ModelB对象
        model_b_id = request.POST.get('model_b_id')
        model_b = ModelB.objects.get(id=model_b_id)

        # 将ModelA对象与ModelB对象建立连接
        model_a.model_b.add(model_b)

        return HttpResponse('数据插入成功！')

from django.urls import path
from .views import MyView

urlpatterns = [
    path('myview/', MyView.as_view(), name='myview'),
]
