How to filter by population result in mongoose?

[Rouben Shekspir]

Hi folks.
Let's consider this situation.I have two mongodb schemas.

    var ChildSchema = new Schema({
        name: String,
        place: {
            type: Schema.Types.ObjectId,
            ref: 'Parent',
            index: true,
            required: true
        }
    });

    var ParentSchema = new Schema({
        name: String
    });

So now I want to get all ChildSchema documents thats parent name is 'bar'. Also I'm using skip,limit, so there will be no case for using manual filtering in Node(it will crash everything).

Sounds like you're trying to do a join. I don't think you can do that in Mongo. Instead, you can find all parents whose name is 'bar', then do a second query to find all the children who reference those parents' ids.

Hope that helps,

Jason
