Explicit call to change event is suppressed #427

Copy link

When I explicitly call a change event, if model is not actually changed.

this.model.trigger('change', this.model);

Such events are suppressed by backbone relational.

This is also swallowing change events when the model is fetched from the server. For example, say an object is partially populated when loading a collection. That model is fetched again when loading a details view. The Backbone.Model fires a "change" event in the sync callback from the fetch. This code in backbone-relational.js swallows this event:

                    if ( eventName === 'change' ) {
                        // `hasChanged` may have gotten reset by nested calls to `set`.
                        changed = dit.hasChanged() || dit._attributeChangeFired;
                        dit._attributeChangeFired = false;

The result is that my view is never rendered as it is waiting for the event that is never delivered.

  `store.unregister` now also accepts collections or a model type
  Change `findOrCreate` to pass `parsedAttributes` to `build`, and adjust tests to reflect change.
  Remove unnecessary locking
  Update change log
  Add test for models not being added to store until they get an id
  Change where we listen to `relational:unregister`.
  Only add models with an id to the store. Closes PaulUithol#411
  Fix a bug in the (crude) performance test
  Add a small test for `clear`
