我有一个Backbone模型，它有以下属性对象，作为Chrome中console.log的输出：

如果我输出model.get('address')，则会返回地址，除了users undefined之外，所有字段都是如此。我不知道发生了什么，因为Backbone.Model.get（）应该返回数组，不应该吗？
这是有问题的模型：
App.Models.PartnerCompany = Backbone.Model.extend({
urlRoot: '/api/v1/partner-companies',
defaults: {
'id' : '',
'name' : '',
'maintenance' : '',
'tyre' : '',
'address' : '',
'town' : '',
'postcode' : '',
'phone' : '',
'fpm_company_id' : '',
}
});
App.Models.PartnerCompany = Backbone.Model.extend({
urlRoot: '/api/v1/partner-companies',
defaults: {
'id' : '',
'name' : '',
'maintenance' : '',
'tyre' : '',
'address' : '',
'town' : '',
'postcode' : '',
'phone' : '',
'fpm_company_id' : '',
'users': 'schroedinger'
},
get: function (attr) {
if (attr != 'id') {
console.log('asked for:', attr, 'value is', this.attributes[attr]);
}
if (attr == 'users') {
console.log(this.attributes);
return this.attributes['users'];
}
return Backbone.Model.prototype.get.call(this, attr);
}
});
并输出model.get（'users'）的返回值。
它给了我这个：
asked for: name - value is: PartnerTest2 application.js:14196
asked for: postcode - value is: 1080 application.js:14196
asked for: town - value is: testTown application.js:14196
asked for: address - value is: testAddress application.js:14196
asked for: phone - value is: 001144778899 application.js:14196
asked for: supplier_no - value is: 3456 application.js:14196
asked for: users - value is: schroedinger application.js:14196

model returned users: schroedinger
因此虽然它自己的属性对象具有正确的值，但它仍然返回默认值。
