Multiple HasMany BelongsTo relation on loopback

I've a model called "jornal" with has two belongsTo relation, with models "obra" and "operario". Both of them have a hasMany relation with "jornal" model.

How can I create an instance of "jornal" model related with an "obra" instance and with an "operario" instance?

I've try chain a post to operario/id/jornal POST sending jornal object (without id, because it's a new instance), and then a POST to obra. If I send without id, it creates a new jornal instance, and if I send the whole object returned from previous POST, it says duplicate id.

Thanks

POST /jornals

with data object

{
  "obraId": 1,
  "operarioId": 1
}

Set ids to whichever 'obra' and 'operario' objects you wish to relate to.

I'm just started with loopback, but I think HasMany polymorphic relation will help you.
