object referencing/mongoose-mongodb
0
I have been taking colt Steeles's web development bootcamp classes,so i am on the associations topic. tried writing code to do a one to many association via object referencing, the code appears thus
var mongoose= require("mongoose");
mongoose.connect("mongodb://localhost/blogApp_demo_2",useNewUrlParser:true);
var postSchema= new mongoose.Schema(
title:String,
content:String
);
var post= mongoose.model("post",postSchema);
var userSchema = new mongoose.Schema(
name: String,
Email:String,
posts:[
type:mongoose.Schema.Types.ObjectId,
ref:"post"
]
);
var user= mongoose.model("user",userSchema);
post.create(
title:"beauty in the lilies",
content: "there is so much to marvel in lilies"
, function(err,post)
user.findOne(email:"deleomoarukhe@yahoo.com", function(err,foundUser)
if(err)
console.log(err);
else
foundUser.posts.push(post);
foundUser.save(function(err,data)
if(err)
console.log(err);
else
console.log(data);
);
);
);
but on trying to execute this code it gives me this error
TypeError: Cannot read property 'posts' of null
tried everything i can to get this code running, to no avail.
p.s the code was to add a further comment to an already existing user.
node.js mongodb mongoose

The error means thatfoundUserisnull. That's because nothing in the database matched the query conditions.email:"deleomoarukhe@yahoo.com"If you think there is a document that matches that, then show the document.
