我在 Express 应用程序中同时使用 Mongoose 和 Mongoosastic，我有 Mongoose Schema course，其中包含 2 个引用trainer和course-category. 这是我的模型定义： Trainer：

let TrainerSchema = new Schema({
    firstname: {
        type: String,
        required: true,
        es_indexed: true,
        es_index: 'not_analyzed',
        es_type: 'string'
    }...
}, { versionKey: false })

TrainerSchema.plugin(mongoosastic, {
    'index': 'training-hub',
    'type': 'trainers',
    'host': 'localhost',
    'port': '9200'
})
let Model = mongoose.model('trainer', TrainerSchema)
exports.Schema = TrainerSchema

课程类别：

let CourseCategorySchema = new Schema({
    name: {
        type: String,
        required: true,
        unique: true,
        es_type: 'multi_field',
        es_indexed: true,
        es_fields: {
            name: {type: 'string', index: 'analyzed'},
            raw: {type: 'string', index: 'not_analyzed'}
        }
    }...
}, { versionKey: false })

CourseCategorySchema.plugin(mongoosastic, {
    'index': 'training-hub',
    'type': 'course-categories',
    'host': 'localhost',
    'port': '9200'
})
exports.Schema = CourseCategorySchema

let Model = mongoose.model('course-category', CourseCategorySchema)

最后，课程：

let CourseSchema = new Schema({
    title: {
        type: String,
        required: true,
        es_indexed: true,
        es_index: 'analyzed',
        es_type: 'string'
    }...
    trainer: {
        type: Schema.Types.ObjectId,
        ref: 'trainer',
        required: true,
        es_indexed: true,
        es_schema: Trainer,
        es_select: 'firstname lastname degree nationality slug photo'
    },
    courseCategory: {
        type: Schema.Types.ObjectId,
        ref: 'course-category',
        required: true,
        es_indexed: true,
        es_schema: CourseCategory,
        es_select: 'name'
    }
}, {versionKey: false})

CourseSchema.index({'trainer': 1, 'title': 1}, {unique: true})
CourseSchema.plugin(mongoosastic, {
    'index': 'training-hub',
    'type': 'courses',
    'host': 'localhost',
    'port': '9200'
}, {
    populate: [
        {
            path: 'trainer', select: '_id firstname lastname degree nationality slug photo'
        },
        {
            path: 'courseCategory', select: '_id name'
        }
    ]
})

当我第一次保存课程时，我得到了在 elasticsearch 中索引的文档和包含所有选定属性的 trainer 字段，除了 _id 和 courseCategory 字段的空文档，当更新同一门课程时，我得到空的 trainer 和 courseCategory .

这是我尝试使用此 API 添加/更新的课程数据示例：

问题是我忘记像@Edgar 说的那样填写我的参考资料，我用过

Course.findOneAndUpdate(...).populate('trainer').populate('courseCategory')

填充我的培训师和 courceCategory 参考资料，现在一切正常
