javascript - 无法在模型 `user` 上找到主键属性。所有模型都必须包含一个充当主键的属性

Question

我有一个如下定义的水线模型，

var Waterline = require('Waterline');
var bcrypt = require('bcrypt');

var User = Waterline.Collection.extend({
identity: 'user',
datastore: 'myMongo',
autoPK: false,
attributes: {
    id: {
        type: 'integer',
        autoIncrement: true,
        primaryKey: true
    },
    email: {
        type: 'string',
        email: true,
        required: true,
        unique: true
    },
    username: {
        type: 'string',
        required: true,
    },

    image: {
        type: 'string'
    },

    password: {
        type: 'string',
        required: true
    },

    mobNo: {
        type: 'string',
        required: true
    },
    aadharNo: {
        type: 'string',
        required: true
    },

    toJSON: function () {
        var obj = this.toObject();
        delete obj.password;
        return obj;
    }
},

beforeCreate: function (values, next) {
    var bcrypt = require('bcrypt');

    bcrypt.genSalt(10, function (err, salt) {
        if (err) return next(err);

        bcrypt.hash(values.password, salt, function (err, hash) {
            if (err) return next(err);

            values.password = hash;
            next();
        });
    });
}
});

module.exports = User;

运行应用程序时，当水线初始化时，我收到以下错误

userError: Could not find a primary key attribute on the model `user`. All models must contain an attribute that acts as the primary key and is guaranteed to be unique.

如您所见，autoPK 为 false，设置了手动主键，仍然得到此信息。

我正在使用“waterline”:“^0.13.1-9”和express。 还剩下什么来创建主键？

谢谢

检查validation Waterline-schema 包中的代码显示主键也必须在架构定义中设置。

var User = Waterline.Collection.extend({
identity: 'user',
datastore: 'myMongo',
autoPK: false,
primaryKey: 'id',
attributes: {
    id: {
        type: 'integer',
        autoIncrement: true,
        primaryKey: true
    }
