返回单个对象而不是数组

Question

我在使用 Django-Tastypie 制作的 API 中创建了一个资源，该资源基于作为 url 参数提供的哈希值返回单个对象。到目前为止，一切都按预期工作，但资源不是只返回一个 JSON 对象，而是返回一个带有单个对象的数组。因为我想将资源连接到 Backbone-Model，所以只有对象会更方便。

资源：

class ObjectResource(CommonResource):
    class Meta(CommonResource.Meta):
        queryset = ObjectModel.objects.all()
        resource_name = 'object'
        allowed_methods = ['get']
        authorization = Authorization()

    def obj_create(self, bundle, **kwargs):
        return super(ObjectResource, self).obj_create(bundle, hash_value=self.hash_value)

    def authorized_read_list(self, object_list, bundle):
        return object_list.filter(hash_value=self.hash_value)

Json 响应

[{"app_enabled": false, "enable_global_note": false, "enable_guest_order_notes": true, "enable_guest_orders": false, "enable_in_house": false, "guest_orders_active": false, "hash_value": "33d96c3c094b54dd918407c3ef79b219", "id": 34, "name": "Spätzlerei", "resource_uri": "", "slug": "spaetzlerei", "state": 0, "time_added": "2013-08-01T20:11:34.689550", "time_modified": "2013-08-06T10:37:01.907677", "vendor": "myorderbird"}]

需要 Json 响应：

{"app_enabled": false, "enable_global_note": false, "enable_guest_order_notes": true, "enable_guest_orders": false, "enable_in_house": false, "guest_orders_active": false, "hash_value": "33d96c3c094b54dd918407c3ef79b219", "id": 34, "name": "Spätzlerei", "resource_uri": "", "slug": "spaetzlerei", "state": 0, "time_added": "2013-08-01T20:11:34.689550", "time_modified": "2013-08-06T10:37:01.907677", "vendor": "myorderbird"}

任何关于如何实现这一点的指针将不胜感激。

您必须使用authorized_read_detail 而不是authorized_read_list 才能检索单个对象而不是具有一个对象的列表。
