do you know how to tail the development log (I assume not because you are using puts statements instead of logger.debug statements). You probably want to get used to using logger.debug(x.inspect) (where x is the variable you want to look at) for debugging.
Please tail the development log and show us the controller action & parameters (copy and paste the whole thing for us). I recommend using http://gist.github.com for sharing code. Also, when asking for help, show us the entire Controller code, beginning with the class definition. (you did not specify if the code is inside of an action) To debug your problem, you need to know what the value of game_params is, which you did not show us. -Jason On Sep 2, 2014, at 4:15 PM, Adrien R. <li...@ruby-forum.com> wrote: > Hello, > > I'm having an error I don't understand for several days.
