Authentication with extra userdata

[Tamas Amon]

Hello!

I made a facebook authentication on my Ember app, but I like to save some datas about the logged in user. I made a model:

import DS from 'ember-data';

export default DS.Model.extend({

  name: DS.attr('string'),

  uid:  DS.attr('string'),

  type: DS.attr('string'),

  other: DS.attr(),

  role: DS.attr('string')

});

The uid is what I get back when the user is azthenticated.

// The data is what I get back from facebook  
signIn(data) {

    let user;

      user = {

        id:     data.uid,

        name:   data.currentUser.displayName,

        userid: data.uid,

        type:   data.provider,

        other:  data,

        role:   'user'

    };
this.store.createRecord('user', user).save()
}

The problem is now every time if the user logged in the app makes a new user. How can I prevent it?

Or if there is a good tutorial about user registration somewhere it will be very nioce

Hey Tamas, 

Sounds like you need a "find or create" pattern. First, search for the user, and if it is not found, create a new one:

return store.find('user', data.uid)

  .then(function(u) {

    console.log('found user with uid', data.uid);

    return u;

  })

  .catch(function () {

    console.log('creating user for uid', data.uid);

    const user = {

      id:     data.uid,

      name:   data.currentUser.displayName,

      type:   data.provider,

      other:  data,

      role:   'user'

    };

    return store.createRecord('user', user);

  })

  .then(function (u) {

   // u = found or created user

   console.log('found or created', u);

   return u;

  });

This github issue details a workaround that you might need, depending on which version of ember-data you're using.

Hope that gets you on a good path,

Tim
