Enable Rails development mode on a Media Temple’s (gs) container
Note this is for emergencies only development will suck up tons of RAM, expose errors/system paths, amongst other undesirable effects.
stop the app
mtr stop [appname]
set development mode
mtr set_option [appname] environment=development
start the app again
mtr start [appname]
debug your app (and fix it, woop!)
stop the app, set productin mode, start the app again; done!
