Sails/Waterline: Return model relation - mysql

Question

So, I'm creating a small application using SailsJS. My database is MySQL.
When I'm testing, first I create a "market" record, then a "stock" record linked to "market" and in another moment, I retrieve this stock record.
I have the following models:
Stock model:
module.exports = {
attributes: {
intern_id: {
type: 'string'
},
tick: {
type: 'string'
},
market: {
model: 'market'
}
}
};
Market model:
module.exports = {
attributes: {
tick: {
type: 'string'
},
name: {
type: 'string'
},
description: {
type: 'string'
},
stocks: {
collection: 'stock',
via: 'market'
},
}
}
Then, first I create a "market" and use the object returned to associate with my "stock" object:
Create and get my market record:
Market.create({tick: 'BVMF', name: 'Bovespa', description: 'Bolsa de Valores'}).exec(function(err, market) {
if(err) done(err);
});
var market = Market.findOne({tick: 'BVMF'}).then(function(results){return results;});
Create my stock record:
Stock.create({intern_id: '1234', tick: 'VALE5', description: 'Vale SA', market: market}).exec(function(err, stock) {
if(err) done(err);
});
And then, when I try to get back this stock, the market object is not retrieved, even if I call populate('market'):
Stock.findOne({tick: 'VALE5'}).populate('market').exec(function(err, record) {
console.log(record);
});

Answer 1

Not too much information, but I guess.
Instead:
Stock.findOne({tick: 'VALE5'}).populate('market').exec(function(err, record) {
console.log(marketObj);
});
Should be:
Stock.findOne({tick: 'VALE5'}).populate('market').exec(function(err, record) {
console.log(record);
});
Second answer:
You forgot about asynchronous. You should do this like that:
Market.create({tick: 'BVMF', name: 'Bovespa', description: 'Bolsa de Valores'}).exec(function(err, market) {
if(err){
done(err);
} else {
Stock.create({intern_id: '1234', tick: 'VALE5', description: 'Vale SA', market: market.id}).exec(function(err, stock) {
if(err){
done(err);
} else {
Stock.findOne({tick: stock.tick}).populate('market').exec(function(err, record) {
console.log(record); // and there is your "Stock" with populated "market"
});
}
});
}
});
