标签: node.js elasticsearch mongoose mongoosastic

我的目标是填充mongoosastic搜索中的某些字段,但如果我执行以下代码,它将始终返回

enter image description here

这是代码

var mongoose = require('mongoose');
var Category = require('./category');
var mongoosastic = require('mongoosastic');
var Schema = mongoose.Schema;

var ProductSchema = new Schema({
  category: { type: Schema.Types.ObjectId, ref: 'Category', es_schema: Category, es_indexed:true, es_select: 'name'},
  name: String,
  price: Number,
  image: String
});

ProductSchema.plugin(mongoosastic, {
  hosts: [
    'localhost:9200'
  ],
  populate: [
    {path: 'category', select: 'name'}
  ]
});

module.exports = mongoose.model('Product', ProductSchema);


var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var CategorySchema = new Schema({
  name: { type: String, unique: true, lowercase: true}
});

module.exports = mongoose.model('Category', CategorySchema);

api.js

router.post('/search', function(req, res, next) {
  console.log(req.body.search_term);
  Product.search({
    query_string: { query: req.body.search_term }
  }, function(err, results) {
    if (err) return next(err);
    res.json(results);
  });
});

我该如何填充mongoosastic中的某个类别?

答案 0 :(得分:0)

您正在使用

#myDiv [class^="col-"] {
}

但代码中的populate: [ {path: 'categories', select: 'name'} ] categories

  

您必须使用类别代替undefined   在模式声明中将键作为类别提到

希望它能解决你的问题。

编辑:

  

类别:{type:Schema.Types.ObjectId,ref:' Category',es_schema:Category,es_indexed:true,es_select:' name'},

=> _category:{type:Schema.Types.ObjectId,ref:' Category' },

并使用populate:.populate(' _category',' name')

希望它会对你有所帮助。
