Rails Setting model

This is a semi-quick key/value store I put together for a quick way to store temporary data related to what's in my database, in a reliable way. For example, I'm using it to keep track of where a hourly and a daily crontask that processes statistics left off, so it can resume only processing and summarizing new data on the next run.

Code quality most likely is not great, but it works. And I will update this gist as I update my project.

How It Works

The settings table has two columns, a key and a value column. The value column is serialized, so you can technically store almost anything in there. Memcache is also used as a caching layer to minimize database calls.

Item.create(
  :name => "Lolcat",
  :fans => 0,
  :views => 0
)

item = Item.find_by_name("Lolcat") #=> <Item name:"Lolcat" fans:0 views:0>

item.increment_attributes({ :fans => 4, :views => 3 })

  Handy url redirection that's as flexible as the href attribute of A tags.
	
  There might have been an easier way to do this, if so, let me know how stupid
  I am :)
	
  Example:
  // Browser is on http://my.domain.com:3000/hello/world.html
  window.redirect_to "world2.html"

# NOTICE: The stop/restart tasks won't work properly due to a bug in the daemons gem

# This will force-load the 'ghazel-daemons' gem and make sure it's used instead of

# UPDATE!
# Instead of using this monkey-patch, it's better if you simply use the following

# Useful to wait for external systems to do something. Like launching daemons
