Because this is now lazy, no network call is actually made.

Network call now gets made within the ActiveResource::Collection class, so this is simply initializing it.

Similar to Rails ORM, check if request was made and re-use that instead of making another http call.

From my point of view Active Resource is a legacy gem. Which means I'm willing to fix simple bugs and whatever is necessary to keep it working on newer rubies and newer Rails, but not willing to do any significant change. |
