为什么mongo中的新文档具有对象而不是ObjectId? [英] Why new documents in mongo have an object and not an ObjectId?

问题描述

在mongodb中插入新文档时，id看起来不像ObjectId，而是看起来像一个对象.

When inserting new documents in mongodb, ids don't look like ObjectId and instead they look like an object.

"_id" : {
        "_bsontype" : "ObjectID",
        "id" : "U\u0013[-Ф~\u001d$©t",
        "generationTime" : 1.43439e+09
}

预期类型:

"_id" : ObjectId("55107edd8e21f20000fd79a6")

我的mongodb版本是3.0.3，这几乎是代码和架构

My mongodb version is 3.0.3 and this is pretty much the code and the schema

var Script = {
    run: function() {
        return CourseModel.findQ()
        .then(function(courses){
            return courses.map(worker);
        }).catch(function(error){
            console.log(error);
        });
    }
};

function worker(course){
    var category = { name: course.name, displayOrder: 0 };
        return CategoryModel.createQ(category).then(function() {
            course.set('name', undefined);
            return course.saveQ();
        });
}
module.exports = Script;

var CategorySchema = new Schema({
    name: {
        type: String,
        required: true,
        unique: true
    },
    active: {
        type: Boolean,
        default: true
    },
    displayOrder: Number,
    updateDate: Date,
    subcategories: [{
        type: Schema.Types.ObjectId,
        ref: 'subcategories'
    }]
});

推荐答案

畸形的ObjectId是由与mongoose-q使用的mongoose版本冲突引起的.您需要将mongoose-q更新到版本0.1.0.我以前使用的是0.0.17，并且看到的行为与您在此处看到的完全相同.

The malformed ObjectIds are caused by a conflict with the mongoose version that mongoose-q is using. You'll need to update to mongoose-q to version 0.1.0. I was using 0.0.17 previously and saw exactly the same behavior that you saw here.
