preventing relations key from being stored on AssociatedModel

[gr2m]

I've a Meeting & a Minute model, as well as a MinutesCollection. Here's my setup, everything works great so far.

var Model = BackboneAssociations.AssociatedModel.extend({
  type: 'meeting',
  relations: [
    {
      type: BackboneAssociations.Many,
      key: 'minutes',
      collectionType: MinutesCollection,
      relatedModel: Minute
    }
  ]
});

On save, I'd not like a meeting model to store the minutes as a property, as I store them separately. I achieve that currently by overiding the toJSON() method like so:

  toJSON: function() {
    var attributes = _.clone(this.attributes);
    delete attributes.minutes;
    return attributes;
  },

That works, but I just want to make double sure that this is the right way to do it and that there are no side effects

Nothing wrong with what you are doing, but you can do it far more easily like this

var MeetingModel = Backbone.AssociatedModel.extend({
  relations: [
    {
      type: Backbone.Many,
      key: 'minutes',
      collectionType: MinutesCollection,
      isTransient : true // Will not serialize `minutes` on `save`
    }
  ]
});

that's what I was looking for, most excellent! Thanks a lot, Dhruva!
