Error while using Node.js. - node.js

Question

This is my model.
UserApiSchema.statics.createApi = function(user,fn){
var instance = new UserApi();
instance.user = user;
instance.apiKey = "asdasdacasdasasd";
console.log("username is " + user.username);
instance.save(function(err){
fn(err,instance);
});
};
UserSchema.statics.newUser = function (email, password,username, fn) {
var instance = new User();
var apiInstance = new UserApi();
instance.email = email;
instance.password =password;
instance.username = username;
instance.save(function (err) {
fn(err, instance);
});
};
This is my controller-users.js:
app.post(
'/signup/',
function(req, res) {
{console.log(req.body.username);
User.newUser(
req.body.email, req.body.password,req.body.username,
function (err, user) {
if ((user)&&(!err)) {
console.log(user.username)
UserApi.createApi(
user,function(err,userapi){
if((!err)){
res.send("APi created")
}
else{
if(err.errors.apiKey){
res.send(err)
}
}
});
req.session.regenerate(function(){
req.session.user = user._id;
res.send("Success here!");
});
} else {
if (err.errors.email) {
res.send(err)
console.log(req.body.password);
console.log(req.body.email);
console.log(req.body);
}
if (err.errors.username) {
res.send(err)
console.log(req.body.password);
console.log(req.body.email);
console.log(req.body);
}
}
});
}
});
The concept is once the user-name/password is accepted, an API key is stored along with the username. Though, the username payload is getting accepted, when I do the UserApiSchema call to generate the api, no such api is generated. No errors either.

Answer 1

Might be real basic ... but, did you create the objects needed?
UserApiSchema = {};
UserApiSchema.statics = {};
UserApiSchema.statics.createApi = function(user,fn){ ...}
If so ... are they in a module?
Did you export them from the module?
exports.userApiSchema = UserApiSchema;
Did you import them in controller-users.js?
var userApiSchema = require('./UserApiSchema.js');
