Sails.js: 由于用法不明确，无法填充模型
Sails.js: Could not populate model because of ambiguous usage
我有两个模型，比如说 A 和 B。这是一个 1:n 关系，其中一个 A 拥有一个 B，并且 B 可以是拥有我的多个 As.
现在，如果可能的话，B 不必知道它所引用的所有 A，所以我仅在 A 侧关联。
现在我想搜索所有拥有 B 的 A，并且符合特定条件。我基本上试过这个：
A.find()
.populate('B', {
where: {
someAttr: 1
}
})
查看文档，我发现这与示例非常相似 there。
现在我收到以下错误：
Could not populate B because of ambiguous usage. This is a
singular ("model") association, which means it never refers to more
than one associated record. So passing in subcriteria (i.e. as the
second argument to .populate()) is not supported for this
association, since it generally wouldn't make any sense. But that's
the trouble-- it looks like some sort of a subcriteria (or something)
was provided!
我能否在不给 B 返回对 A 的引用的情况下使这个查询工作？我觉得这是不必要的模型膨胀。
我现在正在使用 Sails 1.0.1。
正在研究 docs 关于 subcriteria 到 populate 的第二个参数：
When populating collection associations between two models which reside in the same database, a Waterline criteria may be specified as a second argument to populate. This will be used for filtering, sorting, and limiting the array of associated records (e.g. snacks) associated with EACH primary record.
执行此操作的一种方法是检索所有记录然后过滤它们，或者直接使用本机查询。
