feat($resource): allow props beginning with $ to be used on resources


If you expected `$resource` to strip these types of properties before,
you will have to manually do this yourself now.

Is the description on this commit correct? Looks like a copy pasta from c054288

@againsley, what this does is says "when calling toJson() (from src/Angular.js) on a Resource instance, include all enumerable own properties except for $promise and $resolved". In other words, it will include user-specified properties (not $promise or $resolved) --- but will include $eq or $gt or whatever, for example. Previously, it wouldn't.

That said, the test case sure isn't demonstrating this, it's only demonstrating that $promise and $resolved aren't included.



  1. Originally, toJson() would strip away all properties beginning with $. $resource adds 2 proprietary properties on each Resource instance: $promise and $resolved.
    When sending the Resource instance back to the server, those two properties were removed by toJson() and everyone was happy.
  2. c054288 changed the behaviour of toJson() to not strip away properties beginning with $.
    Now, every Resource instance sent back to the server would contain $promise and $resolved (which were unexpected and possibly breaking stuff in the server-side).
  3. This commit adds custom behaviour to Resource instances, so that calling toJson() on them will (additionally to the default behaviour) also strip away $promise and $resolved.
    Everyone was happy again !
