Question

我想扩展模型的查询方法，这就是我写的：

store.query.expose('todos', 'forGroup', function(group) {
return this.where('group').equals(group);
});

但是当我运行应用程序时，控制台说“无法调用未定义的方法公开”，这意味着store.query未定义。为什么？

商店变量是：

var store = derby.createStore({
db: liveDbMongo(mongoUrl + '?auto_reconnect', {safe: true})
, redis: redis
});

我还使用console.log输出商店：

{ domain: null,
  _events: { client: [Function] },
  _maxListeners: 10,
  racer: 
   { get: [Function],
     _plugins: [ [Function: derbyServer] ],
     run: [Function: run],
     createApp: [Function: createApp],
     createStatic: [Function: createStatic] },
  modelOptions: undefined,
  shareClient: 
   { options: { db: [Object], redis: [Object] },
     preValidate: undefined,
     validate: undefined,
     backend: 
      { snapshotDb: [Object],
        getOps: [Function],
        publish: [Function],
        submit: [Function],
        _subscribeChannels: [Function],
        subscribe: [Function],
        fetch: [Function],
        bulkFetchCached: [Function],
        fetchAndSubscribe: [Function],
        queryFetch: [Function],
        query: [Function],
        collection: [Function],
        destroy: [Function] },
     extensions: { '': [] },
     docFilters: [],
     opFilters: [] },
  logger: undefined }

和console.log(store.query)输出undefined。

访问控制Api在0.5版Racer中已更改，此处提到http://blog.derbyjs.com/2013/06/04/migrating-from-derby-0-dot-3-to-0-dot-5/

我没有在认证方面玩过那么多，但是指针是要查看GitHub上的Auth示例 - https://github.com/codeparty/derby-examples/tree/master/auth。
