为"单例"非模型对象创建tastypie资源

您应该能够通过以下方式实现此目的.注意我实际上没有对此进行测试,因此可能需要进行一些调整.在Tastypie文档中可以找到更丰富的示例

class SettingsResource(Resource):
    value = fields.CharField(attribute='value', help_text='setting value')

    class Meta:
        resource_name = 'setting'
        fields = ['value']
        allowed_methods = ['get']

    def detail_uri_kwargs(self, bundle_or_obj):
        kwargs = {}
        return kwargs

    def get_object_list(self, request):
        return [self.obj_get()]

    def obj_get_list(self, request=None, **kwargs):
        return [self.obj_get()]

    def obj_get(self, request=None, key=None, **kwargs):
        setting = SettingObject()
        setting.value = 'whatever value'
        return setting

SettingObject必须支持getattr和setattr方法.您可以将其用作模板:

class SettingObject(object):
    def __init__(self, initial=None):
        self.__dict__['_data'] = {}
        if initial:
            self.update(initial)

    def __getattr__(self, name):
        return self._data.get(name, None)

    def __setattr__(self, name, value):
        self.__dict__['_data'][name] = value

    def update(self, other):
        for k in other:
            self.__setattr__(k, other[k])

    def to_dict(self):
        return self._data
