title: Not sure which Database rails is using
body: <p>I am working on a rails app, where I have created users with scaffolding and saved some entries through the browser. It seems to be doing everything correctly.</p>
  
  <p>The problem is I am not sure which database the app is using. I have mysql but no changes are happening there. Is rails using sqlite instead? If so, how can I switch to mysql or another database?</p>
