I have a MongoDb schema like this
var User = new Schema({
"UserName": { type: String, required: true },
"Email": { type: String, required: true, unique: true },
"UserType": { type: String },
"Password": { type: String }
});
I am trying to create a new user This is done in NodeJs using mongoose ODM And this is the code for creating:
controller.createUser = function (req, res) {
var user = new models.User({
"UserName": req.body.UserName.toLowerCase(),
"Email": req.body.Email.toLowerCase(),
"UserType": req.body.UserType.toLowerCase()
});
models.User.findOne({ 'Email': user.Email }, function (err, olduser) {
if (!err) {
if (olduser) {
res.send({ 'statusCode': 409, 'statusText': 'Email Already Exists' });
}
else if (!olduser) {
user.setPassword(req.body.Password);
user.save(function (err, done) {
if (!err) {
console.log(user);
res.send({ 'statusCode': 201, 'statusText': 'CREATED' });
}
else {
res.send({ 'Status code': 500, 'statusText': 'Internal Server Error' });
}
});
}
}
else {
res.send({ 'statusCode': 500, 'statusText': 'ERROR' });
}
});
};
The for creating new user,I am giving attributes and values as follows:
{
"UserName": "ann",
"Email": "[email protected]",
"UserType": "normaluser",
"Password":"123456"
}
And I am getting error like this:
{"Status code":500,"statusText":"Internal Server Error","Error":{"name":"MongoError","err":"E11000 duplicate key error index: medinfo.users.$UserName_1 dup key: { : \"ann\" }","code":11000,"n":0,"connectionId":54,"ok":1}}
I understand that this error is because UserName is duplicated ,but I haven't set UserName with unique constraint.Whenever I add a new row,I need only email to be unique,UserName can be repeated.How to achieve this??
{ "UserName": "ann", "Email": "[email protected]", "UserType": "normaluser", "Password":"123456" "_id": "5056d1c7e71c8a0c150003b3" }
