Azure移动服务和Ember.js

Question

Hello!

I learning Ember.js as Web-Client Windows Azure Mobile Services from this tutorial.

When I write:

Tothevoidjs.ApplicationRoute = Ember.Route.extend({
    // admittedly, this should be in IndexRoute and not in the
    // top level ApplicationRoute; we're in transition... :-)
    model: function(params) {
        return Tothevoidjs.Secret.findAll();
    }
});

I get this error:

Uncaught TypeError: Object function () {
    if (!wasApplied) {
        Class.proto(); // prepare prototype...
    }
    o_defineProperty(this, GUID_KEY, undefinedDescriptor);

    var m = meta(this), proto = m.proto;
    m.proto = this;
    if (initMixins) {
        // capture locally so we can clear the closed over variable
        var mixins = initMixins;
        initMixins = null;
        this.reopen.apply(this, mixins);
    }

                    if (!bindings) {

    this.init.apply(this, arguments);
    m.proto = proto;
    finishChains(this);
    sendEvent(this, "init");
} has no method 'findAll' 

My app.js:

var Tothevoidjs = window.Tothevoidjs = Ember.Application.create();

var client = new WindowsAzure.MobileServiceClient(
    "link",
    "key"
);

Tothevoidjs.WAMAdapter = Ember.Object.extend({
    table: null,
    init: function() {
        this.table = this.get('table');
    },

    find: function(record, id) {
        var query = this.table.where({
            id: id
        });
        return query.read().then(function(data) {
            Ember.run(record, record.load, data);
        });
    },

    findAll: function(klass, records) {
        var _self = this;

        return _self.table.read().then(function(data) {
            Ember.run(records, records.load, klass, data);
        });
    },

    findQuery: function(klass, records, params) {
        var query = this.table.where(params);
        return query.read().then(function(data) {
            Ember.run(records, records.load, klass, data);
        });
    },

    createRecord: function(record) {
        return this.table.insert(record.toJSON()).then(function(data) {
            Ember.run(function() {
                record.load(data.id, data);
                record.didCreateRecord();
            });
        });
    }
});

/* Order and include as you please. */
require('scripts/controllers/*');
require('scripts/store');
require('scripts/models/*');
require('scripts/routes/*');
require('scripts/views/*');
require('scripts/router');

My model file:

var attribute = DS.attr;

Tothevoidjs.Secret = DS.Model.extend({
    id: attribute('number'),
    body: attribute('string')
});

var client = new WindowsAzure.MobileServiceClient(
    "link",
    "key"
);

Tothevoidjs.Secret.adapter = Tothevoidjs.WAMAdapter.create({
    table: client.getTable('secret')
});

And router:

Tothevoidjs.ApplicationRoute = Ember.Route.extend({
    // admittedly, this should be in IndexRoute and not in the
    // top level ApplicationRoute; we're in transition... :-)
    model: function(params) {
        return Tothevoidjs.Secret.findAll();
    }
});

I do not understand what I did wrong. :(

Please tell me how to avoid this error or what I should read to understand it.

If you need to know version of Ember.js - it's from yeoman generator - 1.0.0

P.S. I'm newbie in web-dev.

您的教程使用 ember-model 库。但是您当前的代码使用 ember-data 版本 1.0.0.beta.x。它们都是用于 Ember 的数据库，具有类似的 API，但不同。

建议您使用 ember-model 库，这样您就能完成教程。

因此，请导入 ember-model 脚本，源代码在此处，确保它在 ember.js 脚本之后，并更改模型定义以使用 ember-model。

var attribute = Ember.attr;

Tothevoidjs.Secret = Ember.Model.extend({
    id: attribute('number'),
    body: attribute('string')
});

我希望它能有所帮助
