so, i tried copying all the files from the devise book examples. got some sqlite3 constraint error. the projects accept other db's, like mysql and mongodb, so i'll probably try and install one of those, and run the files later, but for now i'm going to use this project, as it's working great, just doesn't have all the login features. but it has enough, so i'm going to move onto the more important stuff using this project. good night
