TastyPie和属性

Question

如果我有一个django模型和django字段以及property（）函数调用的某些属性，那么tastypie可以与这个虚拟字段进行交互吗？或者我必须将逻辑包含到tastypie的脱水，obj_create，obj_update函数中？

型号：

class A (models.Model): 
    x = models.CharField() 
    def get_y(self): 
     return self.x 
    def set_y(self, value): 
     self.y = value 
    y = property(get_y, set_y) 

资源可短：

class AResource(ModelResource): 
    class Meta: 
     queryset = A.objects.all() 
     fields = ['id','x','y'] 

还是应只要：

class AResource(ModelResource): 
    class Meta: 
     queryset = A.objects.all() 
     fields = ['id','x','y'] 

def dehydrate(self, bundle): 
    bundle.data['y'] = bundle.obj.x 
    return bundle 


def obj_create(self, bundle, request=None, **kwargs): 
    bundle.obj.y = bundle.data['y'] 
    bundle = super(AResource, self).obj_create(
     bundle, 
     request, 
    ) 

    return bundle 

def obj_update(self, bundle, request=None, **kwargs): 
    bundle = super(AResource, self).obj_update(
     bundle, 
     request, 
    ) 
    bundle.obj.y = bundle.data['y'] 
    return bundle 

如果它可能是短，然后会是什么如果我通过x = 1，y = 2通过tasypie，x等于？

如果您想对来自方法的资源领域，可以包括这样的事情：

method_field = fields.CharField(attribute='my_method')
