Hello! I have this situation where I'd like to allow other developers to write code that works with some other code I'm writing. Basically, I'd like to say "please implement a class which has at least these specific methods and gives me data in this format, and tell me (the code) what this class is so I can call methods on it and use the return values". A little bit like Interfaces in languages like Java or Obj-C allow you to do. It doesn't have to be as flexible as a full blown plugin system!
The actual use case, if it helps clarify my question - I've written code (in Rails) which collates statistics for reporting on e-learning apps (also in Rails, some part of the same app and some completely separate Rails apps) and developers of these apps would like to provide this info, such as "number of lessons passed", "time studied" etc. without having to know too much of the specifics of the reporting code like what models/db tables are used, or how it collates the info etc. My question is - how do you normally handle this in Ruby. Through good documentation? A certain coding pattern? A gem? Thanks! Robert -- You received this message because you are subscribed to the Google Groups "Ruby or Rails Oceania" group.
