backbone.spark's Issues

Don't call function as setter unless there are function parameters

Throw an error instead. This will reduce unwanted behaviour if the user tries to set the wrong attribute or forgets to implement a setter.

Only raise one change event

If you have multiple dependents and they all change, the spark change event will be raised multiple times.
This could be fixed by watching for the change event, not the attribute specific change event.

Context of 'this' is different for setters and getters.

Getter's get model.attributes whereas setters get the model, which means a getter uses model.filePath but a setter uses model.get('filePath').
This is inconsistent.

Implement automatic caching

Backbone.Spark could record the value returned from the spark in a cache, and invalidate the cache when a dependent changes.
This could be optional with a call to useCache() or perhaps noCache() after dependsOn().
