In command mode run :Generate model User name:string.

Now we can create a new User model just inside vim (thanks to vim-rails plugin). Let’s create a new todolist app, enter the new directory and open README.md. ' Add :W command to save as root (sudo write)Ĭommand W :execute ':silent w !sudo tee % > /dev/null' | :edit! Rails programming ' Use 2 characters space only indentation ' Add :DiffOrig command to show differences before savingĬommand DiffOrig vert new | set bt=nofile | r # | 0d_ | diffthis Set mouse=a ' Enable mouse usage (all modes) set showcmd ' Show (partial) command in status line.
