集合未保存mongodb nodejs

Question

我的应用程序(mongodb/nodejs(出现问题，我的目标是保存一个集合：

const Job = require("../models/Job");
exports.saveJob = (req, res, next) => {
const newJob = new Job(req.body);
newJob.gender = 'Male';
newJob.save((err, myjob) => {
myjob.code = '1234';
myjob.save((err, mysavedjob) => {
console.log(mysavedjob);
/** OUTPUT **
* { __v: 0,
updatedAt: 2018-07-31T08:31:47.664Z,
createdAt: 2018-07-31T08:31:47.664Z,
gender:'Male',
code:'1234',
...
}
*/
})
})
}

正如你所看到的，代码输出保存的文档，但当我检查数据库时，我没有代码："1234"我只有

{ __v: 0,
updatedAt: 2018-07-31T08:31:47.664Z,
createdAt: 2018-07-31T08:31:47.664Z,
gender:'Male',
...
}

===更新(添加作业模型(======

const mongoose = require("mongoose");
const JobSchema = new mongoose.Schema(
{
userId: { type: mongoose.Schema.Types.ObjectId, ref: "User" },
code: String,
gender: String,
},
{ timestamps: true }
);
module.exports = mongoose.model("Job", JobSchema, "jobs");

有人能告诉我为什么吗？非常感谢。

我不确定这是保存作业后更改作业的正确方法，但请尝试此

const Job = require("../models/Job");
exports.saveJob = (req, res, next) => {
const newJob = new Job(req.body);
newJob.gender = 'Male';
newJob.save((err, myjob) => {
myjob.code = '1234';
Job.findOneAndUpdate({_id: myjob._id}, myjob, (err, mysavedjob) => {
console.log(mysavedjob);
});
})
}
