Moving to Rails 3 Pain Point: rails server
Update: I have posted a better solution!
Working with rails 2 and 3 projects back and forth, day to day has been pretty painless thanks to rvm and .rvmrc files. That is with the exception of accidentally running rails server on a rails 2 project. I do this all the time and it results in generating a new rails project called server rather then starting the rails server, my actual intention. It’s almost as frustrating when running script/server on a rails 3 project but at least it doesn’t spit out a bunch of useless files. Incidentally, all of the built in rails command (i.e. generate, console, …) set the same trap. To avoid falling prey, I have created a bunch of shell functions which I would like to share with everyone in case they would like to be privy as well.
The shell code is included in the gist below. I load these functions into my .bashrc file (actually my .zshrc file). Once they are are available just get in the habit of running rails-server or rails-generate or rails-whatever and the correct command will always be issued. Also, if anyone knows a better solution, do share!
As one final note, I run rails-server so often that I have is aliased to s. If you would like to do the same add alias s=rails-server to your .bashrc file.
