獲取金字塔

Question

匹配的觀點我有金字塔的服務和這樣的代碼：

@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) 

...... 

的ResultView.get裏面？我怎樣才能匹配看法？

Answer 1

我通過創建一個自定義視圖裝飾器來解決此問題，該裝飾器在request上附加view_id。這個裝飾器根據哪個視圖配置被激活而被調用。這裏有一個例子：

@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) 

而且裝飾：

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 

它讓我完成工作。
