Question

I have two tables:

1 | email1
2 | email2

table2

userid | username
2      | user1
3      | user2


        

Answer 1

You should create model like this

I assumed that you want to do one-by-one association. So this is it.

api/models/Email.js

attributes: {
    email : {
        type: 'email',
        unique: true
    },
    owner : {
        model:'user',  //here put your model name 
        unique: true   //put unique here because it's one by one association
   }
}

api/models/User.js

attributes: {
   username : {
     type: 'string',
     unique: true
   },
   userEmail : {
      collection:'email', //here is also model name
      via: 'owner'
   }
}

Then

Get user from email

Email.find().populate('owner')

Get email from user

User.find().populate('userEmail')

Now you can access to your data both from your two model.

Try to print two command above you will see that your data contain the data from related table.

Email.find().populate('owner').exec(function(err, records) {
    res.json(records)
});

This is my response.

[
    {
        "owner": {
            "username": "test",
            "id": 1,
            "createdAt": "2016-11-23T13:45:06.000Z",
            "updatedAt": "2016-11-23T13:45:06.000Z"
        },
        "email": "test@test.com",
        "id": 1,
        "createdAt": "2016-11-23T13:45:06.000Z",
        "updatedAt": "2016-11-23T13:45:06.000Z"
    }
]
