随着我在 CompoundJS 世界中的进步，我遇到了两种定义模式的方法：
第一的：
var Product = describe('Product', function () {
property('upc', String);
property('name', String);
set('restPath', pathTo.products);
});
第二：
var Schema = require('jugglingdb').Schema;
var schema = new Schema('memory');
var Product = schema.define('Product', {
upc: { type: Number, index: true },
name: { type: String, limit: 150, index: true },
createdAt: { type: Date, default: Date.now },
modifiedAt: { type: Date, default: Date.now }
}, {
restPath: pathTo.products
});
第一个，工作，但看起来像一个旧的设计。第二个，不起作用，但这是根据 JugglingDB 文档的方法。
我应该使用哪一个？为什么第二个对我不起作用？
更新： 这是我使用第二个错误时遇到的错误：
