Change block of code based on external config file?

In PHP, i would have a config file that says something like $account = 'on' and then 开发者_开发技巧throughout my project, i would have if else based on whether that variable equaled on or off.

Now im trying to do something similar in RoR. However, i am pretty new to RoR and considering all the features and implementations rails have, im thinking there has to be a method to basically take a block of code, wrap it in something that says if on, display, if not, dont.

Any suggestions?

# Put this in an initializer
@config = YAML::Load(open([Rails.root, "config/options.yml"].join("/")))

if @config[:account] == "on"
   # do this...
else
   # do this...
end

Take a look at nifty-generators(config generator) or configatron and chose one which better fits your needs and looks more elegant to you.
