用django-tastypie添加命令API的最佳方式是什麼？

Question

我有以下模型，我想允許用戶使用django-tastypie以API 加入活動。

# Conceptual, may not work. 
class Event(models.Model): 
    title = models.CharField('title', max_length=255) 
    users = models.ForeignKey(User) 

    def join(self, user): 
     self.users.add(user) 
    def leave(self, user): 
     self.users.remove(user) 

# join the events with API like... 
jQuery.post(
    '/api/v1/events/1/join', 
    function(data) { 
     // data should be a joined user instance 
     // or whatever 
     alert(data.username + " has joined."); 
    }, 
); 

但我不知道這樣做的最佳方法。我應該創建EventJoinResource就像

# Conceptual, may not work. 
class EventJoinResource(Resource): 
    action = fields.CharField(attribute='action') 

    def post_detail(self, request, **kwargs): 
     pk = kwargs.get('pk') 
     action = kwargs.get('action') 
     instance = Event.objects.get(pk=pk) 
     getattr(instance, action)(request.user) 

resource = EventJoinResource() 

# ??? I don't know how to write this with django-tastypie urls 
urlpatterns = patterns('', 
    ('r'^api/v1/events/(?P<pk>\d+)/(?P<action>join|leave)/$', include(resource.urls)), 
) 

我該怎麼辦？任何建議，歡迎:-)

我想你可以創建「EventResource」。然後，您可以爲加入的用戶，離開的用戶以及任何其他操作提供不同的活動。所以基本上也可能是「EventTypeResource」。

然後每一個事件發生時，您只需將POST到「EventResource」指定事件的類型（通過指定EventTypeResource集合的元素）和任何額外的數據，這樣的：

jQuery.ajax ({ 
    url : '/api/v1/events/', #note the collection URI not the element URI 
    data : { 
     type : '/api/v1/event-types/<pk_of_the_event_type', #URI of EventTypeResource 
     extra_data : { ... } 
    }, 
    success : function(data) { 
     // data should be a joined user instance 
     // or whatever 
     alert(data.username + " has joined."); 
    } 
);
