Hi,Thanks for the suggestions. I've restructured my application a bit, but am running in to problems with 'repo' not being defined in the controller. I'm actually a bit confused about where the method to commit the files should go. My thinking is that it should be in the model (as that handles validation and persistence) and the controller call it If this is not the correct way to do things I'd be glad to here any suggestions.
Also I'm currently creating the 'repo' object, then giving it to the method as an argument. Can I create it inside the method then just call the '.commit_all' method on it?
Do I even need my own method? Can I just create the repo object in the model then call repo.commit_all on it?
My revised controller and model are attached. Thanks, Jen. On 18/05/11 12:49, Robert Walker wrote:

For example, take a look at the following: -------------------- def my_method(arg) puts "hello world" end my_method -------------------- Running the above script generates this error: -------------------- ArgumentError: wrong number of arguments (0 for 1) method my_method in demo.rb at line 4 at top level in demo.rb at line 4 -------------------- If you can figure out why the above fails, then you should be able to figure out why your application is producing that same error.

It's a valuable skill to know how to read error messages, and follow stack traces from your programing language. It's something all developers need to practice. Don't let errors like this freak you out. If you take the time to understand them, they often tell you exactly what's wrong, and exactly where to look.
