Javascript Mongodb嵌套文档更新?
上面我给出了存储在数据库(mongodb)中的数据。在这里,我想更新剩余的电话和预订的电话。在这里 我正在尝试更新,但它没有更新,因为我创建了嵌套文档,请帮助我完成更新 给定我在Angular前端服务器中编写的代码Javascript Mongodb嵌套文档更新?,javascript,arrays,angularjs,node.js,mongodb,Javascript,Arrays,Angularjs,Node.js,Mongodb,上面我给出了存储在数据库(mongodb)中的数据。在这里,我想更新剩余的电话和预订的电话。在这里 我正在尝试更新,但它没有更新,因为我创建了嵌套文档,请帮助我完成更新 给定我在Angular前端服务器中编写的代码 { "_id": { "$oid": "5705f793e4b0acd6e2456804a" }, "Categories": [ { "mainmodels": [ {

当我运行此命令时,它会点击后端服务器路由
credentials =
{
"Categories.mainmodels.submodels.Bookedphones": '1',
"Categories.mainmodels.submodels.Remainingphones":'9'
}
$http.put('http://localhost:3000/phones/' + '5705f793e4b0acd6e2456804a', credentials).success(function(data, status, headers, config, response) {
});
对于查找id,我正在使用此
app.route('/phones/:findId')
.get(phones.read)
.put(phones.update)
.delete(phones.delete);
app.param('findId', phones.phomesByID );
用于更新我使用的
exports.phomesByID = function(req, res, next, id) {
Phones.findById(id).populate('user', 'displayName').exec(function(err, phones) {
if (err) return next(err);
if (! phones) return next(new Error('Failed to load Phones ' + id));
req.phones = phones ;
next();
});
};
我做过这样的模型
exports.update = function(req, res) {
console.log(req.phones);
var phones = req.phones ;
phones = _.extend(phones , req.body);
console.log(phones);
phones.save(function(err) {
if (err) {
return res.status(400).send({
message: errorHandler.getErrorMessage(err)
});
} else {
res.jsonp(phones);
}
});
};
从您的代码中,我看到您没有直接嵌入手机,而是创建了一个嵌入文档数组,为了让mongo了解您正在尝试做什么,您的更新查询应该是这样的:
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
var submodelSchema = {
submodelname: {type:String, required: false},
price: {type:String, required: false},
Remainingphones: {type:String, required: false},
Bookedphones: {type:String, required: false},
Numofphones: {type:String, required: false}
};
submodelSchema = 'new Schema('+ submodeleSchema +',{_id:true})';
var typeSchema = {
vtype: {type:String, required: false},
mainservices: {
Status: {type:String, required: false},
modelname : {type:String, required: false},
fromdate: {type:String, required: false},
todate: {type:String, required: false}
},
submodels: [submodelSchema], default:[]
};
typeSchema = 'new Schema('+typeSchema +',{_id:true})';
var PhoneSchema = new Schema({
rank: {
type: String,
default: '',
trim: true
},
name: {
type: String,
default: '',
trim: true
},
Categories: [typeSchema], default:[]
});
mongoose.model('Phone', PhoneSchema);
这个模式设计似乎有点奇怪,我建议你修改它,它不是很直观。你有没有收到任何错误?没有,我没有收到错误。我收到200条回复,但当我签入数据库时,它并没有更新
var credentials = {
"Categories[0].mainmodels[0].submodels.Bookedphones": '1',
"Categories[0].mainmodels[0].submodels.Remainingphones":'9'
};
