More surprises followed :).
Because if now one of the inheriting ruby classes defines an
initialize method then it is mapped to the initialize method of the C#
base class. This
initialize method of my controller is totally different from the
initialize method of the parent controller in C# it wouldn't be an override. Is
there a way to tell IronRuby it shouldn't walk up the chain except when
called super and to disregard the C# implemented method? I tried using
alias_method but that didn't help.
public abstract class ControllerBase {
public virtual void Initialize(RequestContext context){
// do stuff here
}
}
/* More Subclasses in C# go here none override Initialize */
class Controller < System::Web::Mvc::IronRuby::Controllers::RubyController
# An attempt to put the base method out of play
alias_method :base_controller_initialize, :initialize
# This approach had different problems
# undef_method :initialize
def initialize; end
end
class ApplicationController < Controller
def initialize(user_svc=nil)
@user_service = user_svc||UserService.new(uow_scope)
end
end
In the ApplicationController it now says that the first argument is of type
RequestContext which isn't what there is supposed to be there. It should be
a UserService
In this case the initialize method is not that extremely important because
it was there to make unit testing easier. I can set the dependencies some
other way. At this point I'm more curious about how it works or will work in
the future, CLR interop has been very interesting so far :)
