Improved scaffold controller generator template. The comments and the json format has been removed and a before filter has been added to fetch the resource. The controller has now also been updated to use the strong parameters gem. This can be added to an existing application at: lib/templates/rails/scaffold_controller/controller.rb

	<% if namespaced? -%>
	require_dependency "<%= namespaced_file_path %>/application_controller"

	<% end -%>
	<% module_namespacing do -%>
	class <%= controller_class_name %>Controller < ApplicationController

	include ActiveModel::ForbiddenAttributesProtection

Example Capistrano deploy file. This is a basic example that I plan to improve soon. Update 1: Added :admin_runner option to ensure deployment directories are created with the correct owner. Update 2: Added better support for multiple environments and added rails:console rails:dbconsole tasks.

	require 'rvm/capistrano'
	require 'bundler/capistrano'
	require 'capistrano/ext/multistage'
	load 'deploy/assets'

	set :stages, ["staging", "production"]
	set :default_stage, "production"

	set :user, '?'
	set :admin_runner, '?'

Some useful unix commands for managing processes. Basic stuff but very useful.

	# List all processes of type for a user
	pgrep -u <user> <process name>

	# Example:
	pgrep -u app_user ruby



	# Kill all processes of type for a user
	killall -u <user> <process name>
