title: finding a ruby gem for config settings that can be updated from web interface
body: <p>I am creating a rails web app that is a really a content management system. Thus there is going to be a admin section of the app. There I want users to be able to set config setting that are available through the app. Thus I want basic CRUD functionality for config settings. (If you've ever used the admin section of the Discourse discussion board, you'll know what I want to do)</p>
  
  <p>Most of the config gems I have seem to be about organizing config info during development, but seem to expect that config info to be basically set and static on production. (See <a href="https://stackoverflow.com/questions/1450285/how-to-define-custom-configuration-variables-in-rails">How to define custom configuration variables in rails</a>)</p>
  
  <p>However, in the above link there was one gem called rails-settings (<a href="https://github.com/Squeegy/rails-settings" rel="nofollow noreferrer">https://github.com/Squeegy/rails-settings</a>) that, in its description, seemed very close to what I want. However, it seems very old (last commit was 2009).</p>
  
  <p>Three related questions:</p>
  
  <p>1) Is there is a standard Gem for this kind of thing that I'm missing? </p>
  
  <p>2) Should I use rails-settings?</p>
  
  <p>3) Should I just create my own model called Settings &lt; ActiveRecord and would this model be available throughout all my controllers?</p>
