Supports Rails 3 & 4
Add a hook like before_filter to your controllers that gets executed between when your action is completed and the template is rendered. It can really DRY up loading some data that is used for views (headers / layouts / etc).
Plugin was inspired by before_render by Todd Willey, which works for rails2 only. New ActiveSupport::Callbacks methods were used, in analogy with ActionDispatch.
Warning: Rails 3 & 4 only. Rails2 users can use before_render by Todd Willey.
before_render / prepend_before_render / skip_before_render works as other filters. Options like :except and :only can be passed to filter.
class PostsController < ApplicationController before_render :ping, :except => [:destroy] def index; end def new; end def show; end def destroy; end private def ping Rails.logger.info "Ping-Pong actions" end end
Method ping will be executed after your actions and before template is rendered.
- Tests should not throw runtime error(happening right now if comment one of provided aliased methods)
