Python常见问题
我试图用django变量将数据显示到模态体中。我对ajax和django很在行。ajax函数传递Galeria对象的id，然后视图返回带有数据的JsonResponse。莫代尔为什么不获取数据？如果I console.log也打印数据，但是当我尝试通过django变量传递数据时，模式显示为空。我做错了什么
我的观点
def get_galeria(request):
galeria = Galeria.objects.get(id=int(request.GET['ajax_galeria']))
print(galeria.id)
context = {}
context['galeriaID'] = galeria.id
context['galeriaNombre'] = galeria.nombre
return JsonResponse(context, safe=False)
