My app was working fine until I tried to open it in Netbeans. Netbeans created a project and connected it to MySQL instead of SQLite3 which is what I was using. I guess it wants my app to run on JRuby. Anyway, I run rails server in my cmd and go to localhost:3000 in my browser and it said I need to download a gem for mysql. I wanted to switch back to SQLite3 so I switched my database.yml file back to what it is on this site. Now I try localhost:3000 and I get ActiveRecord::ConnectionNotEstablished. Please help, I’d love to be able to go back to learning RoR.
