获取金字塔中的匹配视图

Question

我有这样的金字塔服务和代码：

@view_defaults(route_name="result", context=Result, renderer="json")
class ResultView(RESTView):
    """
    Rest view for exercise results
    """

    @view_config(request_method='GET', permission='view', role="owner")
    @view_config(request_method='GET', permission='view', role="admin")
    @view_config(request_method='GET', permission='view', role="gadmin")
    @schema(Result)
    @log("get result")
    def get(self):
        """
        Gets result
        """

        return self.get.__schema__.dictirialize(self.context, prepare_json=True)

......

如何在ResultView.get内找到匹配的视图？

Answer 1

我通过在view_id上创建附加request的自定义视图装饰器来解决此问题。根据哪个视图配置被激活来调用此装饰器。这是一个例子：

    @view_config(request_method='GET', role="owner", permission="view", decorator=view_id("owner"))
    @view_config(request_method='GET', role="admin", permission="view", decorator=view_id("admin"))
    @view_config(request_method='GET', permission="view")
    @schema(User, excludes=('password', 'deleted'), key="owner")
    @schema(User, key="admin")
    @log("get user")
    def get(self):
        return self.get.__schema__[self.request.id].dictify(self.context)

装饰者：

def view_id(id):
    """
    Pyramid view decorator that remembers the view id and assigns it to request
    """

    def _view_id(view):
        def view_callable(context, request):
            request.id = id
            return view(context, request)

        return view_callable

    return _view_id

它为我完成了工作。
