按照手册应该是可以的

给定一个对象、一个数据字典或两者，构建一个 Bundle 以在整个脱水/水合物循环中使用。

所以我用 Resource 把它放在一起

def get_list(self, request, **kwargs):

    bundles = []

    foo = {}
    foo['bar'] = 1

    bundle = self.build_bundle(data=foo, request=request)
    bundles.append(self.full_dehydrate(bundle))

    serialized = {}
    serialized[self._meta.collection_name] = bundles
    serialized = self.alter_list_data_to_serialize(request, serialized)
    return self.create_response(request, serialized)

但是即使我通过它，full_hydrate()它也会窒息。bar我在这里想念什么？

您尚未指定queryset或object_class在Meta模型资源的类中。使用时至少应指定其中之一ModelResource。

您可以通过obj作为参数传递给build_bundle方法来避免这种情况，例如

bundle = self.build_bundle(obj=MyModel(), data=foo, request=request)

参考

好吃的 v0.9.15

  1. build_bundle
  2. 如果指定，则设置object_class使用。queryset.modelqueryset
