rails 中使用 mongodb 查询结果与预期不同

hging — Wed, 18 Jun 2014 13:23:44 +0800

首先给出两行查询代码: 1、 Shop.collect{|s| puts s.id if s.recommend == 1}

2、 Shop.where(:recommend => 1).collect{|s| puts s.id}

想要实现的结果就是 查出所有 Shop 表中字段 recommend 的值为 1 的数据

预期结果代码 1 的返回是正常的，但是代码 2 返回的结果少于预期值。

然后对比代码 2 与代码 1 返回的结果，其中代码 2 返回结果全部可以再代码 1 中找到，

然后查看代码 1 返回的数据，抽出一条没有在代码 2 返回的结果，用如下代码进行查询

Shop.find("shop_id").recommend 结果返回为 1

很奇怪，求解答两个方法查询结果为什么有差别。
