Rails - Mar 2010 - Plugin : adding filters in ApplicationController

Hi everybody !

I''m trying to extend the class ApplicationController with a plugin to
add filters to follow some executions. I don''t know why, but I observed
a weird behaviour and I don''t know why. Here is my code.

init.rb
========require ''myplugin''

myplugin.rb
===========ApplicationController.class_eval do
  before_filter do
    puts "I''m in the before_filter"
  end
end

The things is this filter happens just the first time (the first action
after Webrick is loaded). Well, I tried to do the same thing, extending
ActionController::Base, and it works without problems. But I''d like to
extend ApplicationController and not the Base.

Any ideas ?

In development mode your code gets reloaded between requests - the
reloaded application controller class doesn''t have this filter added
to it.

One way of working around this is for your plugin to add a method to
base (eg add_my_filter) and call that from whichever controllers use
it.
There is also a hook ( config.to_prepare ) that it called before each
request in development mode
