问题 My Django Model: class myModel(models.Model): myIntA = models.IntegerField(default=0) My View: myModelList = myModel.objects.all() for i in range(len(myModelList)): myModelList[i].myIntB = i return render( request, 'myApp/myTemplate.html', Context( { "myModels": myModelList, } ) ) Is the above legal?
