Question

我正在尝试保存与另一个模型有关系的模型：

exports.portfolioSchema = new Schema({
    name: {type: String, required: true, unique: true},
    isActive: {type: Boolean, default: true}
});

exports.projectSchema = new Schema({
    name: {type: String, required: true, unique: true},
    isActive: {type: Boolean, required: true, default: true},
    portfolio: {type: mongoose.Schema.Types.ObjectId, ref: 'portfolioSchema', required: true},
    isCodeBaseFullyOwned: {type: Boolean, required: true, default: false}
});

尝试保存时：

Project = store.model('Project', schema.projectSchema);
var p = new Project();
p.name = project;
Portfolio.findOne({"name":activePortoflios[0]}, '_id', function (err, data) {
    p.portfolio = data._id;
});
p.isActive = true;
p.save(function (err) {
    if (err) console.log(err);
});

我收到以下错误：

        kind: 'required',
        path: 'portfolio',
        value: undefined } },
  message: 'Project validation failed',
  name: 'ValidationError' }

我有什么遗失的吗？ data._id产生类型ObjectId，我还需要设置其他内容吗？

findOne是异步调用。因此，当您尝试保存它时，不会返回findOne回调。由于属性portfolio是必需的，因此未通过验证。

Project = store.model('Project', schema.projectSchema);
var p = new Project();
p.name = project;

Portfolio.findOne({ name: activePortoflios[0] }, '_id', function (err, data) {
    if (err) return handleError(err);
    p.portfolio = data._id;
    p.isActive = true;
    p.save(function (err) {
        if (err) console.log(err);
    });
});

无法使用对另一个对象的引用来保存猫鼬模型
