arrays - 将文档推送到 Mongoose 模型数组中的子文档中

Question

在我的公司架构中，我有一个已发布的职位，其类型为数组，并将保存子文档

companySchema.js

PostedJobs : [{
        JobName : { type: String, required : true},
        JobType : { type: String, required : true},
        JobLocation : { type: String, required : true},
        JobSalay: { type: String, required : true}
    }],

在我的/company route ，我通过模型中的 Creator 实体获取特定用户注册的所有公司

获取我使用的用户公司

  router.get('/',  isLoggedIn ,  function(req, res, next) {
    Company.find({'Creator': req.user.id}).then(function(companies) {
        res.render('Company', { "Companies" : companies });
    });
});

获取公司后，我想通过单击公司名称(唯一)来访问特定公司页面

router.get('/:name' , isLoggedIn , function(req , res , next) {
    var name = req.params.name;
    Company.findOne({Name : name}).then(function(Company) {
         res.render('dashboard',{
            "Company" : Company,
             errors : []
        });
    })
});

现在我想通过 POST 路由向该特定公司发布工作，如下所示 我的 req.body 由 JobName 、 JobType 、 JobLocation 和 JobSalary 组成，我已将它们分配给特定变量，现在我应该如何将此文档推送到数组

POST 路线

router.post('/:name' , isLoggedIn , function(req , res , next) {
    var JobName = req.body.JobName;
    var JobType = req.body.JobType;
    var JobLocation = req.body.JobLocation;
    var Salary = req.body.Salary;
    //push this job to that specific comapny
});

我不知道你们公司的架构，但是如果你想将PostedJobs添加到公司中，你应该在其中定义一个数组字段。

router.post('/:name' , isLoggedIn , function(req , res , next) {
    var JobName = req.body.JobName;
    var JobType = req.body.JobType;
    var JobLocation = req.body.JobLocation;
    var Salary = req.body.Salary;
    //push this job to that specific comapny
    // create the postedJob object
    var postedJob = {JobName : JobName, JobType : JobType, JobLocation : JobLocation, JobSalay:Salary};
    // find the company in DB and add the postedJob to its array of postedJobs
    var name = req.params.name;
    Company.findOne({Name : name}).then(function(company) {
        //modify and save the object received via callback
        company.postedJobs.push(postedJob);
        company.save();
    });
});
