== DESCRIPTION
KVC (Key-Value Configuration) provides a powerful, transparent way to maintain
mutable app settings in the database.
== FEATURES/PROBLEMS
* Transparent: no generators or migrations to run.
* Powerful: quick access; automatic updates; scales quickly.
For more rigidity/safety: http://github.com/stephencelis/acts_as_singleton
== SYNOPSIS
Need a mutable setting in the database? Just add it, KVC-style:
KVC.key = "value"
You're set.
Any value will do:
KVC.last_import = Time.zone.now
However you do:
KVC.site_messages.unshift("Downtime expected at 0800.").pop
Store related settings together in a hash to reduce queries:
KVC.homepage_settings = { ... }.with_indifferent_access
KVC.homepage_settings # => { ... }
If need be, validate specific key values in an initializer:
# config/initializers/kvc_config.rb
KVC::Settings.config do
validates("password") { |value| value =~ /\d+/ }
end
== REQUIREMENTS
* Rails 2.3.2 or greater.
== INSTALL
=== As a gem
Install:
% gem install kvc
And configure:
config.gem "kvc"
=== As a plugin
Install:
% script/plugin install git://github.com/stephencelis/kvc.git
Or submodule:
% git submodule add git://github.com/stephencelis/kvc.git vendor/plugins/kvc
=== Anything else?
Just restart your server, and you should be good to go. The key-value table
will migrate transparently when the model first loads.
If you uninstall the plugin, you will be prompted to drop the table (to drop
the table at any time, execute the "kvc:drop_table" Rake task).
