title: What is the best way to keep web app config?
body: <p>If I have some config for web admin to set e.g. number of post per page, some enum showing choice. How should I keep this settings in db ? Should I serialize it and save as blob.</p>
  
  <p>Thanks,</p>

  <p>I using rails and I want it to dynamically change this setting through web interface, so I think environment.rb would not fit this situation. So I should have a extra table with two tuples as name, value ?</p>
