//モデル

'use strict'; 

const mongoose = require('mongoose'); 

const Schema = mongoose.Schema; 

const DoctorSchema = new Schema({ 
fname: {type: String, required: true}, 
registrationNo: {type: String}, 
gender: { type: String}, 
//to save image's url 
img: {type:String}, 
}); 
const DocModel = mongoose.model('DocModel', DoctorSchema); 
module.exports = DocModel; 


    //route 

const express = require('express'), 
mongoose = require('mongoose'); 

const Doctor = mongoose.model('DocModel'); 
var bodyParser = require('body-parser'); 
var formidable = require('formidable'); 
var fs = require('fs'); 

const Router = express.Router(); 


//route to post 
Router.post('/DoctorRegistration', (req, res) => { 
    //json object to save in database 
    var doc = new Doctor(); 
    //declare variable to store other field values 
    var user = {}; 
    var form = new formidable.IncomingForm(); 
    form.parse(req, function (err, fields, files) { 
    //assign field values to user 
    user = JSON.parse(fields.user); 
    //path to save image 
    var newpath = ""; 
    //check whether file is null 
    if (files.file != null) { 
      var oldpath = files.file.path; 
     //save image in disk 
     newpath = './public/assets/docImg/' + user.fname+'.jpg'; 
      fs.rename(oldpath, newpath, function (err) { 
       if (err) throw err; 


     }); 
     //assign image path to save in database 
     doc.img = newpath; 
    } 
    doc.fname = user.fname; 
    doc.registrationNo = user.registrationNo; 
    doc.gender = user.gender; 
    //save object in database 
    doc.save(function (err) { 
     if (err) { 
      console.log(err.message); 
      res.json({success: false, message: 'User information 
      already exsits'}); 
     } 
     else { 
      console.log(doc); 
      res.json({success: true, message: "user created"}); 

     } 
     }); 

    }); 


});
