I'm currently trying to make a register form using mongoDB and nodeJS - I've created new database and collection - I want to store: username, password, email and insert_time in my database.
I've added unique indexes to username/email and checked if it works - and I can not add a duplicated entry using mongo's console or rockmongo (php mongodb manager) - so it works fine.
However - when the piece of code that is supposed to register a new account is being executed and makes an insert with the data that is already in database - it returns an object that contains all the data that was supposed to be added with a new, unique id. The point is - it should return an error that would say that entries can not be duplicated and insert failed - instead it returns the data back and gives it a new id. Data that already resides in database remains untouched - even the ID stays the same - it's not rewritten with the new one returned by script's insert.
So, the question is... what am I doing wrong? Or maybe everything is fine and database's insert should return data even if it's failed?...
I even tried defining indexes before executing indexes. I tried inserting the data using mongoDB's default functions and mongoJS functions - the result is the same in both cases.
The code I'm trying to execute (for mongoJS):
var dbconn = require("mongojs").connect('127.0.0.1:27017/db', ['users']);
var register = function(everyone, params, callback)
{
// TODO: validation
dbconn.users.ensureIndex({username:1},{unique:true});
dbconn.users.ensureIndex({email:1},{unique:true});
dbconn.users.save(
{
username: params.username,
password: params.password,
email: params.email,
insert_time: Date.now()
},
function(error, saved)
{
if(error || !saved)
{
callback(false);
}
else
{
console.log(error);
console.log(saved);
callback(true);
}
});
}
For both cases - inserting new data and inserting duplicated data that doesn't modify database in any way - ERROR is null and SAVED is just a copy of data that is supposed to be inserted. Is there any way to check if insert was made or not - or do I have to check whether the data already exists in database or not manually before/after making an insert?
