I'm totally sure this has been asked and answered 1_000_000 times, but Google has let me down on this one. I'm using a link to trigger an ajax call that create a row in the database. On successful completion, a row in the DOM is appended.
Getting around to the question (you knew there was a question in here someplace, right?), I'm trying to return some JSON on success or an array of errors on failure. My failure also sets the HTTP status to "406 Unprocessable Entity". Firebug confirms this is all happening, but my $.ajax call always triggers the success: callback.
What is the magic differentiator that $.ajax uses to discern between a successful and failing server response?
TIA Steve
