Django数据返回自定义

1.数据返回 一种是views里面返回数据 但是这种数据没办法自定义

2.直接在类里面定义@property 针对对象进行自定义

class ApiIdc(View):
    def get(self,request,*args,**kwargs):
        pk = kwargs.get('pk')
        if pk:
            obj = Idcc.objects.get(id=pk)
            data = obj.to_dict
        else:
            idcs = Idcc.objects.all()
            data = {'data':[s.to_dict for s in idcs]}


        return  JsonResponse(data)
        

class ApiIdc(View):
    def get(self,request,*args,**kwargs):
            pk = kwargs.get('pk')
            if pk:
                data = Idcc.objects.filter(id=pk)
            else:
                data = Idcc.objects.all()
            print(data)
            idcdata = data.values()
            print(idcdata)
            resdata = {'data':[s for s in idcdata]}
            print(resdata)
            return  JsonResponse(resdata)

class Idcc(models.Model):
    name = models.CharField(max_length=20)
    address = models.CharField(max_length=20)
    @property
    def to_dict(self):
        ret = dict()
        for attr in [f.name for f in self._meta.fields]:
            value = getattr(self, attr,None)
            ret[attr] = value
        return ret
