Question

图片 This is how ist's displayed on the web 我想访问对象部分以使用EJS显示数据。我无法访问对象数据。

我的架构

let Subject = mongoose.Schema({
  name:[],
  crh:[]
});

let Program = mongoose.Schema({
  name: String,
  semester: Number,
  subject:[Subject]
});

let School = mongoose.Schema({
      name:{
        type: String,
      },
      program:[Program]
})

从数据库访问日期的POST方法

router.post('/view',(req,res) =>{
  let school = req.body.school;
  let semester = req.body.semester;
  let program = req.body.program;
  All.find({name:school,"program.name":program,"program.semester":semester},(err,record) =>{
    if(err) throw err;
    if(!record){
      req.flash("error","We couldn't find any relevant document! ");
      res.redirect('/admin/view');
    }
    if(record){
      console.log(record);
      res.render("./admin/viewSub",{find:record});
    }
  })
})
