Currently, I am delving into the world of Mongodb. To kick things off, I initiated by executing npm install --save mongoose uuid within the confines of Terminal. The primary objective of my project revolves around storing user information in the database.
Post running node index.js in Terminal, my expectation is to witness:
About to save!
Saved!
Unfortunately, what greets me in Terminal is (shown below):
This is the content of index.js:
var mongoose = require('mongoose');
var uuid = require('uuid');
var Schema = mongoose.Schema;
/* Novel code from recommended source with an error */
var promise = mongoose.connect('mongodb://localhost:testMongo/testMongo', {
useMongoClient: true,
});
promise.then(function(db) {
db.model();
connection.openUri('mongodb://localhost:testMongo/testMongo', { /* options */ });
var userSchema = new Schema({
email: {
type: String,
unique: true
},
password: {type: String},
todos: [
{
text: {type: String}
}
]
});
userSchema.pre('save', function(next) {
console.log("About to save!");
var user = this;
user.password = uuid.v4();
next();
});
var User = mongoose.model('user', userSchema);
var email = '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9febfaecebdfebfaecebb1fcf0f2">[email protected]</a>';
// var user = new User({
// email: email
// });
//
// user.save(function(err) {
// if(err) {
// return console.log(err);
// } else {
// return console.log("User was saved!");
// }
// })
//
// console.log("Outside of callback!");
var text = "This is a todo.";
User.findOne({email: email}, function(user, err) {
if(err) {
return console.log(err);
}
if(!user) {
return console.log("Couldn't find user!");
}
var count = user.todos.push({
text: text
});
console.log(count);
user.save(function(err){
if(err) {
console.log(err);
} else {
console.log("Saved!");
}
});
});
An error shown in Terminal:
(node:14312) DeprecationWarning: `open()` is deprecated in mongoose >= 4.11.0, use `openUri()` instead, or set the `useMongoClient` option if using `connect()` or `createConnection()`. See http://mongoosejs.com/docs/connections.html#use-mongo-client
