I’ll have to re-duplicate the exact error message on ruby’s side. From what I recall, this was obscured by a bunch of weird error messages that were deep in the codebase for rubyamf.<\/p>\n

Basically, if your rails server barfs a bunch of errors when you try and load activerecord objects from an amf request, one cause of this can be the fact that you have associations setup in your rubyamf_config.rb file, and there are bad or missing foreign keys in the database for linking associated tables.<\/p>\n

In the following example ruby barks when an account is loaded. Account has a location_id in the database to a location. If the location record with that id does not exist, ruby does not throw a nice error.<\/p>\n
