用 django-tastypie 添加命令 api 的最佳方法是什么？

Question

我有以下模型，我想允许用户使用 API 加入活动 使用 django-tastypie。

# 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.");
    },
);

但我不知道最好的方法。我应该创建EventJoinResource 之类的

# 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)),
)

我该怎么办？欢迎任何建议:-)

Answer 1

我认为您可以创建“EventResource”。然后，您可以为用户加入、用户离开和任何其他操作设置不同的事件。所以基本上也有“EventTypeResource”可能会很好。

然后每次发生事件时，您只需 POST 到“EventResource”，指定事件的类型（通过指定 EventTypeResource 集合的元素）和任何额外的数据，如下所示：

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.");
    }
);
