Hello all,
I''ve created a simple plugin to extend the functionality of my
controllers. So in my plugins/<plugin>/lib directory I created the
following module:
module MyPlugin
def self.included(base)
include InstanceMethods
end
module InstanceMethods
def some_method
..
end
end
end
To extend the controllers just put
include MyPlugin
somewhere in ApplicationController and that''s it... I thought!
I found out that ''include InstanceMethods'' will only work if
my
application is running in ''development''. When running in
''production''
calling ''some_method'' will result in a
ActionController::UnknownAction
exception.
If I change the ''include'' line into:
base.send(:include, InstanceMethods)
things will work fine, so after all there''s no problem at all, but
I''m
just curious of someone of has the same experience and if there''s a
difference between ''include'' and ''base.send
:include''?
Thanks in advance.
(I''m using Rails 1.2.6).

I suspect you''re just been lucky: in development mode you keep getting reloaded, so the first time round the methods aren''t added to ApplicationController, but they are added to MyPlugin, and the second and following times since they are in MyPlugin they are also added to ApplicationController. When class caching is on (ie in production) things are only loaded once and so the methods aren''t added to the controllers. (not sure if you''re doing this on purpose, but do you know that what you''ve got there is equivalent to module MyPlugin def some_method end end )> Thanks in advance. > > (I''m using Rails 1.2.6). > -- > Posted via http://www.ruby-forum.com/. > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi Frederick, Thanks so much for your response. It made it all so much clearer, and, I must admit, now reading your explanation, I''ve had to figure it out myself... There is no reason for using ''base.send :include'' instead of just including the module. To be honest, I changed my code to your suggestion.
