.load(relations) not loading models

Introduction

I’m doing a model.load(['role.event', 'user']).then(m => m.related('role').related('event')) and the event is coming up as an empty event Model. However the event definitively exists and the foreign keys are defined. I’m doing this in the created event on the model, if that could be the source of the issue?

Steps to reproduce issue

class Event extends Bookshelf.Model {
  roles() {
    return this.hasMany('EventRole', 'event_id');
  }
}

class EventRole extends Bookshelf.Model {
  event(){
    return this.belongsTo('Event', 'event_id');
 }
applications() {
    return this.hasMany('EventApplication', 'event_role_id');
  }
}

class EventApplication extends Bookshelf.Model {
  role() {
    return this.belongsTo('EventRole', 'event_role_id');
  }
initialize(){
 this.on('created', model => model.load(['role.event', 'user']).then(m => m.related('role').related('event')), this)
}

Expected behaviour

To load the event model

Actual behaviour

Doesn’t load the event model.

The strange thing is the load gets called for 3 EventApplications and the last one loads the event, the others dont.

Even awaiting the transactions doesnt reliably work.

seems you can’t await a transaction. Makes sense

[davidfurlong]

If the model was created inside a transaction, the created event can fire before the transaction has completed. Pass through the transacting in the 3rd argument and await the promise to fix this
