Mongodb类型参考节点 [英] Mongodb type reference node

问题描述

我正在尝试引用节点模型中的另一个对象，

I am trying reference another object in a model in node,

User = new Schema({
        username: {
            type: String,
            index: {unique: true}
        }
});

Idea = new Schema({
        Creator: {
            type: User
        }
});

但出现此错误Undefined type at "creator" Did you try nesting Schemas? You can only nest using refs or arrays.，我相信我想使用refs，但找不到有关它的文档，有人可以帮助我.谢谢

but I get this error Undefined type at "creator" Did you try nesting Schemas? You can only nest using refs or arrays. I believe I want to use refs, but could not find documentation on it, can some one help me out. Thanks

推荐答案

我在这里找到了自己的问题的答案.

I found out the answer to my own question here it is.

User = new Schema({
    username: {
        type: String,
        index: {unique: true}
    }
});

Idea = new Schema({
    Creator: {
        type: Schema.ObjectId,
        ref: 'User'
    }
});
