@object('c_ctxapi_340_trigger_object')
class TriggerObject extends CortexObject {

  @trigger('create.before', { name: 'c_before_create_trigger', object: 'c_ctxapi_340_trigger_object', weight: 1 })
  beforeCreate({ context }) {
    context.update('c_before', new Date().getTime())
  }

  @trigger('create.after', { object: 'c_ctxapi_340_trigger_object', weight: 1 })
  afterCreate({ context }) {
    org.objects[context.object].updateOne({ _id: context._id }, {
      $set: {
        c_after: new Date().getTime()
      }
    }).execute()

}

// Override create.before trigger
@object('c_ctxapi_340_trigger_object')
class MyCustomTrigger {
  @trigger('create.before', { name: 'c_before_create_trigger', object: 'c_ctxapi_340_trigger_object', weight: 2 })
  beforeCreate({ context }) {
    context.update('c_before', 'overwritten data')
  }
}
