sails-postgresql "ReferenceError: User is not defined"

I try to set up postgresql connection with sails.js . Here is my config:

api/models/User.js:

module.exports = {

tableName: 'user',
meta: {
    schemaName: 'public'
},
identity:'sails',
connection: 'postgreSQL',

attributes: {
username:{
    type:'string',
    required:true,
},
password:{
    type:'string',
    required:true,
},
email:{
    type:'email',
    required:true,
},
}};

config/connections.js:

module.exports.connections = {
postgreSQL: {
      adapter: 'sails-postgresql',
      host: '127.0.0.1',
      user: 'sails', // optional
      password: 'pass', // optional
      database: 'sails', //optional
      port:5433,
    }
}

config/models.js

module.exports.models = {
  connection: 'postgreSQL',
  migrate: 'safe',    
};

api/controllers/UserController.js

module.exports = {
    create: function(req,res){
        User.create(req.allParams()).exec(function createdUser(err, created){
            if(created != undefined){
                sails.log('Utilisateur créé')
                res.view('User/user_created');
                sails.log(req.allParams())
            }
            else
            {
                sails.log('Pas d\'utilisateur créé')
                sails.log(req.allParams())
            }

        });
    },

    search: function(req,res){
    sails.log("Recherche saisie:")
    sails.log(req.allParams())
    if(req.allParams() == undefined){
        sails.log("Pas d'utilisateur recherché");
    }
    else {
        User.find({username : {contains: req.allParams().username}}).exec(function (err, userFound){
        sails.log('utilisateur trouvé');
        sails.log(userFound);
        return res.json(userFound);
    })
    }
    }
};

When I lift my app, and i send the following request (which send post agument as params for "create" action from UserController):

http://127.0.0.1:1337/User/Subscribe?username=pierre&password=pass&[email protected]

I have the error:

However all works perfectly without postgresSQL connection... Does someone know how to solve this ?

Thank you in advance for help.

EDIT: I changed the files path to get the good ones

Actually, the file paths were wrong in my first post. I had set up the right ones in my app.

The problem was in the file config/models.js. I was trying to run my app with the safe mode for my connection. However, this doesn’t work during the first run. The good way is to use either the alter or drop mode for your connection in order to create tables corresponding to your models during the first run.

The good config/models.js file is:

module.exports.models = {
    connection: 'postgreSQL',
    migrate: 'alter',  // you can also use 'drop' 
};

I also had to change my model to look like so:

module.exports = {
    attributes: {
        username: {
            type: 'string',
            required: true,
        },
        email: {
            type:'string',
            required:true,
        },
        password: {
            type: 'string',
            required: true,
        },
    }
};

It looks like you are missing the model file for your User table.

It should be in api/models/User.js

I think you just need to move the file api/controllers/User.js to make it work.

Also renamed your api/controller folder to be api/controllers

Sails is convention based, if you put things in the right place it will work without fuss. So your model files need to go in

api/models/TABLENAME.js api/controllers/TABLENAMEController.js

If both of these files are present, it will create the table and declare global variable TABLENAME for you.
