DEPRECATEDยถ โ
This gem is no longer maintained. However, there is a complete rewrite of this gem maintained here:
_Old README below_
Settings Pluginยถ โ
Settings is a plugin that makes managing a table of global key, value pairs easy. Think of it like a global Hash stored in you database, that uses simple ActiveRecord like methods for manipulation. Keep track of any global setting that you dont want to hard code into your rails app. You can store any kind of object. Strings, numbers, arrays, or any object.
Installationยถ โ
Install the rails-settings gem
gem install rails-settings
And include the gem in your apps config
config.gem 'rails-settings', :lib => 'settings'
Or install as a plugin if you must. But gems are cooler.
./script/plugin install git://github.com/Squeegy/rails-settings.git
Setupยถ โ
You must create the table used by the Settings model. Simply run this command:
ruby script/generate settings_migration
Now just put that migration in the database with:
rake db:migrate
Usageยถ โ
The syntax is easy. First, lets create some settings to keep track of:
Settings.admin_password = 'supersecret' Settings.date_format = '%m %d, %Y' Settings.cocktails = ['Martini', 'Screwdriver', 'White Russian'] Settings.foo = 123
Now lets read them back:
Settings.foo # returns 123
Changing an existing setting is the same as creating a new setting:
Settings.foo = 'super duper bar'
Decide you dont want to track a particular setting anymore?
Settings.destroy :foo Settings.foo # returns nil
Want a list of all the settings?
Settings.all # returns {'admin_password' => 'super_secret', 'date_format' => '%m %d, %Y'}
Set defaults for certain settings of your app. This will cause the defined settings to return with the Specified value even if they are not in the database. Make a new file in config/initializers/settings.rb with the following:
Settings.defaults[:some_setting] = 'footastic'
Now even if the database is completely empty, you app will have some intelligent defaults:
Settings.some_setting # returns 'footastic'
Thatโs all there is to it!. Enjoy!
