Ruby is already using the class name of my model


I'm making a forum application with various levels of authorization, one of which is a Monitor. I am doing this by extending my User class, and I plan on fine tuning this with "-ship" classes (e.g. administratorship, authorship, moderatorship, etc.). Apparently the Monitor class is part of ruby mixin. How do I keep my resource name without the collisions?


Solution

  • Some possibilities:

    • avoid the require 'monitor.rb' call which is pulling in the standard Monitor instance
    • do some runtime magic to rename the existing Monitor class.
    • monkey with your load path so that require 'monitor.rb' pulls in an empty implementation of Monitor.

    But in all cases you could end up with the situation where a 3rd party library is using Monitor expecting it to be the standard Monitor class. So, I'd advise against any of the above.

    I'd say your only two reasonable options are:

    A) you could put your class in a namespace:

    Module MyApp
      class Monitor
        #...
      end
    end
    

    if your app uses some kind of auto-require magic (e.g it's a rails app) then you would put your implementation in /my_app/monitor.rb. When you wanted to refer to that class you would do something like my_monitor = MyApp::Monitor.new(), or whatever.

    B) you could use a different class name :)
