为什么mongoosastic填充/弹性搜索没有填充我的一个引用?我得到一个空的对象
问题描述:
我有两个模型,我试图引用。风格和品牌。为什么mongoosastic填充/弹性搜索没有填充我的一个引用?我得到一个空的对象
品牌填充所需的对象,但样式始终为空。
我试过清除缓存/删除索引。带和不带include_in_parent并键入:'嵌套'。
我觉得它可能与指定的es_type等有关。不知道。
产品架构:
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var Style = require('./style');
var Brand = require('./brand');
var mongoosastic = require('mongoosastic');
var ProductSchema = new mongoose.Schema({
name: { type: String, lowercase: true , required: true},
brand: {type: mongoose.Schema.Types.ObjectId, ref: 'Brand',
es_type:'nested', es_include_in_parent:true},
style: {type: mongoose.Schema.Types.ObjectId, ref: 'Style',
es_schema: Style, es_type:'nested', es_include_in_parent: true},
year: { type: Number }
});
ProductSchema.plugin(mongoosastic, {
hosts: [
'localhost:9200'
],
populate: [
{path: 'style'},
{path: 'brand'}
]
});
Product = module.exports = mongoose.model('Product', ProductSchema);
Product.createMapping(function (err,mapping) {
if(err){
console.log('error creating mapping (you can safely ignore this)');
console.log(err);
}else{
console.log('product mapping created!');
console.log(mapping);
}
});
var stream = Product.synchronize();
var count = 0;
stream.on('data', function(){
count++
});
stream.on('close', function(){
console.log('indexed whisks ' + count + " documents");
});
stream.on('error', function(){
});
风格模式:
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var mongoosastic = require('mongoosastic');
var StyleSchema = new mongoose.Schema({
name: { type: String, lowercase: true , required: true},
});
Style = module.exports = mongoose.model('Style', StyleSchema);
Style.createMapping(function(err, mapping){
if(err) console.log('error w/ mapping : ', err);
console.log('mapping created');
console.log(mapping);
})
var stream = Style.synchronize();
var count = 0;
stream.on('data', function(){
count++
});
stream.on('close', function(){
console.log('indexed styles ' + count + " documents");
});
stream.on('error', function(){
});
搜索查询:
exports.topSearch = function(req, res) {
console.log(req.body, "search product")
Product.search({query_string: {query: req.body.search}}, {from: req.body.fromNum,
size: req.body.size,
hydrate: req.body.hydrate
},
function(err, results) {
if (err) console.log('ERR', err);
if (results){
var data = results.hits.hits.map(function(hit) {
return hit
});
console.log('product data', data)
res.send(data);
}
else {
res.send({errmsg:'results not defined'})
}
});
};
当我询问,我得到这样的结果一击即中:
_source:
{ name: 'Redemption White Rye Whiskey',
brand: [Object],
style: {},} },
有关评论的请求:被添加到数据库
产品:
exports.create = function(req, res) {
Product.create(req.body, function(err, product) {
if (err) {
console.log('ERR', err)
};
res.send({
product: product
});
});
};
前/角:
$scope.add = function() {
var prodStyle = JSON.parse($scope.selectedStyle);
$scope.product = $scope.product._id;
$scope.product.style = prodStyle._id;
console.log($scope.product.style, 'prod style');
Product.create($scope.product).then(function (res) {
res.data.product.style = { name: prodStyle.name };
$scope.products.push(res.data.product);
$scope.product = {};
$scope.selectedStyle = {};
});
};
答
我找到了工作,但它与这个有很大的不同在npm/github上给出的例子。
我不得不删除es_schema:Style(正如我为品牌意外完成的,这就是它的工作原理)。我必须添加从elasticsearch和mongoosastic文档收集的es_type:“嵌套”/ es_include_in_parent。
我不知道这样做的目的,但它似乎工作:
style: {type: mongoose.Schema.Types.ObjectId, ref: 'Style',
es_type:'nested', es_include_in_parent:true},
我现在得到:款式:[对象]根据需要,当我CONSOLE.LOG results.hits。
下面是故宫给出的例子,这并没有为我工作:
var Comment = new Schema({
title: String
, body: String
, author: String
});
var User = new Schema({
name: {type:String, es_indexed:true}
, email: String
, city: String
, comments: {type: Schema.Types.ObjectId, ref: 'Comment',
es_schema: Comment, es_indexed:true, es_select: 'title body'}
})
User.plugin(mongoosastic, {
populate: [
{path: 'comments', select: 'title body'}
]
})
你能后的代码,您使用提交文件?弹性搜索/ mongoosastic查询的 –
,或者我如何添加产品?我已添加查询和一些其他信息。 – NoobSter
对不起,我的意思是添加产品 –
