To demonstrate:

class MyClass
    private
    def say_hello(name)
        puts "Let's go back to my place, #{name}."
    end
end

my_object = MyClass.new
So we get smacked if we try:
> my_object.say_hello
Nomethoderror: private method `say_hello' called for #<MyClass:0x820b4>
	from (irb):8
	from :0
but instead:
> my_object.send :say_hello, "world"
Let's go back to my place, world.

Touché!

Now, honestly, this strikes me as odd. Conceptually, I don't see whysend should function differently from an ordinary method call with respect to access control.

= Exception Notifier Plugin for Rails

First, include the ExceptionNotifiable mixin in whichever controller you want
to generate error emails (typically ApplicationController):

  class ApplicationController < ActionController::Base
    include ExceptionNotifiable
    ...
  end

Then, specify the email recipients in your environment:

  ExceptionNotifier.exception_recipients = %w(joe@schmoe.com bill@schmoe.com)

And that's it! The defaults take care of the rest.

I <3 Ruby On Rails

at my ruby nightjob i hack for fun. this is a part of the urbantakeover "who or what the fuck are you looking for?" just like Wikipedia's disambiguation pages.

The quick & dirty way only searches for Users and Spots at the moment, which works for astera (spot & user) but fails at metalab (spot & team).

Thus we'll hack together a dynamic solution:
stuff = []
[User, Spot, Team].each do |model_class|
stuff << model_class.find_by_name params[:name]
end

if stuff.size == 1
thing = stuff.first
  redirect_to :controller => thing.class.name.downcase, :action => 'show_by_name', :name => thing.name
else
#shows a wikipedia style "disambiguation" page
@things = stuff
render :template => 'disambiguate'
end
note, i haven't tried this yet, but it *should* work.

eval is your friend

at my python dayjob i'm writing a chat protocol. it should be possible to extend the protocol later on by adding new subprotocols (command sets) to achieve this i use listeners for each additional subprotocol.

the quick and dirty way to get some is:
self.listeners = {
'chat' : ChatListener(environment, self),
'table' : TableListener(environment, self),
'stats' : StatsListener(environment, self) }

but as soon as you have to add a lot of listeners it get's tedious to duplicate all the <code>*Listener(environment, self)</code> cruft.

so to keep things DRY i took the dynamic route:
listener_names = ['chat', 'table', 'stats', 'more', 'evenmoar', 'cthulhu', 'lol', 'catz']
self.listeners = {}
for listener_name in listener_names:
_class = eval("%sListener" % listener_name.capitalize())
self.listeners[listener] = _class(environment, self)

which looks super confusing, but is SUPER EFFECTIVE!

also circular references are teh suck. i want code running in contexts. to be able to omit the self parameter.

but maybe i'm doing it wrong.
