猫鼬填充不适用于 ObjectIds 数组

Shr*_*awa 2 mongoose mongodb node.js mongoose-populate mongoose-schema

这是我的架构:

/** Schemas */
var profile = Schema({
    EmailAddress: String,
    FirstName: String,
    LastName: String,
    BusinessName: String
});

var convSchema = Schema({
    name: String,
    users: [{
        type: Schema.Types.ObjectId,
        ref: 'Profiles'
    }],
    conversationType: {
        type: String,
        enum: ['single', 'group'],
        default: 'single'
    },
    created: {
        type: Date,
        default: Date.now
    },
    lastUpdated: {
        type: Date,
        default: Date.now
    }
});

/** Models */
db.Profiles = mongoose.model('Profiles', profile);
db.Conversations = mongoose.model('ChatConversations', convSchema);

module.exports = db;

然后我尝试使用以下代码(http://mongoosejs.com/docs/populate.html)填充用户:

db.Conversations.find(query).populate('users').exec(function (err, records)     {
    console.log(records);
});

这是返回recordsusers数组作为一个空白数组[]

我也尝试了另一种方式(http://mongoosejs.com/docs/api.html#model_Model.populate):

db.Conversations.find(query, function (err, records) {
    db.Conversations.populate(records, {path: "users", select: "BusinessName"}, function (err, records) {
        console.log(records);
    });
});

结果是一样的。当我将引用检查到个人资料集合记录时。

知道这里有什么问题吗?

我通过重命名模型(第三个论点)使其工作:

mongoose.model( "Profiles", profile, "Profiles" );

问题是猫鼬正在搜索profiles集合,但它Profiles在数据库中。所以我将它重命名Profiles为匹配确切的名称。

噗!谢谢我。
