node.js - 具有ElasticSearch映射和Mongoosastic的MongoDB

Question

我正在尝试使用NodeJs的mongoosastic插件将现有集合索引到ElasticSearch。这是我的架构:

const callCenterSchema = new mongoose.Schema({
    _owner : { type: mongoose.Schema.Types.ObjectId, ref: 'User', es_type: 'object' },
    ivrs: [{
        name: {
            type: String,
            es_type: 'string'
        },
        ivrType: {
            type: String,
            default: 'mobile',
            enum: ['mobile', 'website'],
            es_type: 'string'
        },
        submenu: {
            type: [ CallCenterSubmenu.schema ],
            es_type: 'nested',
            es_include_in_parent: true
        }
    }]
});

callCenterSchema.plugin(mongoosastic, {
    esClient: require('tusla/lib/db/elastic').elastic,
    populate: [
        { path: '_owner' }
    ]
});

let CallCenter = mongoose.model('CallCenter', callCenterSchema);
CallCenter.synchronize()

CallCenter.createMapping(function(err, mapping) {
  if (err) {
    console.error('Error creating mapping for CallCenters', err.message);
  }
});


module.exports = CallCenter;

我的子菜单架构如下:

const callcenterSubmenuSchema = new mongoose.Schema({
    name: String,
    key: String,
    waitTime: {
        type: Number
    },
    waitSuffix: String,
    numberOrLink: String,
    auth: {
        canBeSkipped: String,
        fields: {
            type: Array,
            es_type: 'object'
        },
        verification: String,
        regExp: String
    },
    submenu: [this]
}, { _id: false });

我不断收到此特定错误，但无法解决。谢谢您能帮助我。

谢谢!

为CallCenters创建映射时出错[mapper_parsing_exception]在字段[submenu]上未声明类型[mixed]的处理程序

Answer 1

我想问题是那条线:

 type: [ CallCenterSubmenu.schema ]

在错误消息中它说:

No handler for type [mixed] declared on field [submenu]

因此，您正在尝试将submenu字段的类型指定为fixed(或者，我不确定，elasticsearch会推断出它的类型)，并且我知道没有类型为mixed。因此ES会触发该异常。您必须指定一个有效的类型:https://www.elastic.co/guide/en/elasticsearch/reference/master/mapping-types.html
