push value of one schema into another schema-CodePudding

i have a file ./models/Image.js

const { Schema, model } = require('mongoose');

const imageSchema = new Schema({
    title: {type: String},
    description: {type: String},
    author:{type:String},
    filename: {type: String},
    path: {type: String},
    originalname: {type: String},
    mimetype: {type: String},
    size: { type: Number},
    created_at: {type: Date, default: Date.now()},
    authorname:{type:String}
});
module.exports = model('Image', imageSchema);

I have another file ./models/User.js

const mongoose = require('mongoose');

const UserSchema  = new mongoose.Schema({
  name :{type:String,required : true} ,
  email :{type  : String,required : true} ,
  password :{type  : String,required : true} ,
  date :{type : Date,default : Date.now}
});

const User= mongoose.model('User',UserSchema); 
                                            
module.exports = User;

and a function inside routes/user

router.post('/upload', async (req, res) => {
    const image = new Image();
    image.title = req.body.title;
    image.description = req.body.description;
    image.filename = req.file.filename;
    image.path = '/img/uploads/'   req.file.filename;
    image.originalname = req.file.originalname;
    image.mimetype = req.file.mimetype;
    image.size = req.file.size;
    //image.authoremail= User.req.email; // what should i do here
    
    await image.save();
    res.redirect('/user/feed');
});

What i want is to put users name and email inside image schema so that i can compare it for later purposes for example in a page of dashboard user is only shown the picture he/she has uploaded but inside page 'feed' pictures of all users is displayed with there respective name

CodePudding user response：

In my opinion you should add user name and email field in the image schema. then set required = false, if it's not required for every case or you can add it without custom the schema by set strict = false in schema. it allow you to save or update the document in your case.

this is the answer that show how to set strict = false https://stackoverflow.com/a/50935227/15072782

CodePudding user response：

You can change the image Schema by using,reference document concept. So that you can just store user id.

const imageSchema = new Schema({
    title: {type: String},
    description: {type: String},
    author:{type:String},
    filename: {type: String},
    path: {type: String},
    originalname: {type: String},
    mimetype: {type: String},
    size: { type: Number},
    created_at: {type: Date, default: Date.now()},
    authorname: {                                      // update here
      type: Schema.Types.ObjectId, 
      ref: 'User' 
    }
});
module.exports = model('Image', imageSchema);


const mongoose = require('mongoose');

const UserSchema  = new mongoose.Schema({
  name :{type:String,required : true} ,
  email :{type  : String,required : true} ,
  password :{type  : String,required : true} ,
  date :{type : Date,default : Date.now}
});

const User= mongoose.model('User',UserSchema); 
                                            
module.exports = User;
