Error using sails.js and postgreSQL (using sails-postgresql module) - node.js

Question

I want to ask a question. I'm developing an app using sails.js and PostgreSQL (using sails-postgresql module). I'm using UUID for my primary key type instead of integer. But there are some error when I try to insert a data to my database.
my model UserModel.js
var uuid = require('node-uuid');
module.exports = {
adapter: 'somePostgresqlServer',
autoPK: false,
migrate: 'safe',
attributes: {
ID: {
primaryKey: true,
type: 'string',
defaultsTo: function (){
return uuid.v4();
},
unique: true,
index: true,
uuidv4: true
},
username: {
type: 'string',
required: true,
unique: true
}
}
};
my create function in the controller
create: function(req, res) {
if (!req.param('_username') || !req.param('_newPassword') ||
!req.param('_confirmPassword') || !req.param('_emailAddress') ||
!req.param('_firstName') || !req.param('_lastName')) {
var errorMessage = ["All field are required to sign up"];
req.session.flash = {
err : errorMessage
}
res.redirect('/login');
return;
}
if (req.param('_newPassword') != req.param('_confirmPassword')) {
var errorMessage = ["New password and confirm password must be same"];
req.session.flash = {
err : errorMessage
}
res.redirect('/login');
return;
}
UserModel.create({
username: req.param('_username'),
encryptedPassword: req.param('_newPassword'),
emailAddress: req.param('_emailAddress'),
firstName: req.param('_firstName'),
lastName: req.param('_lastName')
}).exec(function(err,post) {
if (err) {
return res.error();
}
res.redirect('/');
})
res.redirect('/');
}
the error

I wish you can help me. Thanks for your attention :)

Try this:
Model
var uuid = require('node-uuid');
module.exports = {
adapter: 'somePostgresqlServer',
autoPK: false,
attributes: {
id: {
primaryKey : true,
type : 'string',
defaultsTo : function (){
return uuid.v4();
},
unique : true,
index : true
},
username: {
type : 'string',
required : true,
unique : true
}
}
};
Controller
create: function(req, res) {
var username = req.param('_username'),
newPassword = req.param('_newPassword'),
confirmPassword = req.param('_confirmPassword'),
emailAddress = req.param('_emailAddress'),
firstName = req.param('_firstName'),
lastName = req.param('_lastName');
if (!(username || newPassword || confirmPassword || emailAddress || firstName || lastName)) {
var errorMessage = ["All field are required to sign up"];
req.session.flash = {
err : errorMessage
}
return res.redirect('/login');
}
if (newPassword != confirmPassword) {
var errorMessage = ["New password and confirm password must be same"];
req.session.flash = {
err : errorMessage
}
return res.redirect('/login');
}
UserModel
.create({
username : username,
encryptedPassword : newPassword,
emailAddress : emailAddress,
firstName : firstName,
lastName : lastName
})
.then(function(post) {
res.redirect('/');
})
.catch(res.negotiate);
}
At models definition, there are no exist migrate, it's on model configuration.
uuidv4 also not a valid attribute.
id field is necessary while you use Blueprint API, look after blueprint hooks at actionUtil in your sails at node_modules.
Don't call res.redirect at the end of controller while you have async. process, it will give race condition when query not completed yet and you will get redirected.
Actually I don't pretty sure if it will solve your problem, but you can try it and give a result later.
