I want to scan my erb files looking for specific custom HTML tags (I have done this part) and then before rendering, intercept these tags and replace their html output. I can't find any info relating to this sort of activity in RAILS. Maybe I am not looking in the right place.

Hey,
maybe you could do sth like:
class PostsController < ApplicationController
acts_as_special
def show
@post = Post.find(params[:id])
respond_to do |format|
format.html { my_renderer }
end
end
end
and write a plugin or sth:
# Module to Extend a given Controller with the acts_as_special methods
module MyRenderer
def self.included(base)
base.extend(ClassMethods)
end
module ClassMethods
def acts_as_special
include MyRenderer::InstanceMethods
end
end
module InstanceMethods
def my_renderer
.. do sth with the code ....
render :template => ...
end
end
end
ActionController::Base.class_eval do
include MyRenderer
end
well you dont need to write a plugin, you yust have to make "your" render method available for the controller.
if you have a different/better method, please let me know!
