How to change code on live Ruby On Rails -

i new ruby on rails.

i have site deployed on server , i'm accessing putty hostip , rsa key.

how can update code on deployed site? if code modified, have rebuild (or run) code?

just edit code using editor (vim, nano, or whatever), restart web server. that's not right way it. should edit in local machine, , use deployment tool capistrano. see below.
