Eil, vedendo la mail di Cluter V. sul rinominare una app rails m’ venuto in mente di chiedere di nuovo se qualcuno si fatto una gem/rake task/script awk per rinominare qualcosa dentro una app rails in modo furbo. Ovvero, una cosa tipo rails rename foo bar che faccia .1 un rename di file e directory “convenzionali” app/models/foo.rb → bar.rb app/controllers/foos\_controller.rb → bars.rb app/views/foos/ → /views/bars/ test/unit… .2 un replace dentro il resto dei file delle occorrenze di Foo, ‘foo/bar’, FooController, @foo etc .3 una bella migrazioncina che rinomini la tabella foos in bars e i riferimenti foo\_id in bar\_id Premesso che nn funzioner nel 100% dei casi etc etc… io avevo uno script che faceva una parte del lavoro, ed era comodo. Ma era due hard-drive-non-backuppati fa … – twitter: @riffraff blog (en, it): www.riffraff.info [riffraff.blogsome.com](http://riffraff.blogsome.com) work: [circleme.com](http://circleme.com) ---

C’è [GitHub - galkn/Rename: Plugin for easily renaming your Rails3 app](https://github.com/get/Rename) che non ho mai provato perché normalmente uso 2 script one-liner fatti con egrep, ma che adesso non ho a portata di mano Sulla CLI propongo: - rails rename old new Che fa vedere file e riga di dove verrà la sostituzione - rails rename old new -f Che procede effettivamente Luigi ---

Ti incollo la risposta che ho dato su stackoverwlow a una domanda simile: If you use the -i option you need to provide an extension for your backups. If you have: File1.txt File2.cfg The command: sed -i ‘.original’ ‘s/old\_link/new\_link/g’ \* create 2 backup files like: File1.txt.original File2.cfg.original You can use sed -i ‘’ ‘s/old\_link/new\_link/g’ \* to ignore backups. > Quindi il comando da usare è: grep -lr -e ‘OldApp:’ \* | xargs sed -i ‘’ ‘s/OldApp:/NewApp:/g’ – Duilio R.

Ho creato una gem che può essere integrata facilmente in qualsiasi app e si usa tramite rake. Testate, forkate, aggiungete pure se volete rinominare modelli e/o migration. > **[GitHub - grigio/rails\_rename: An easy way to rename a Rails app](https://github.com/grigio/rails_rename)** > > An easy way to rename a Rails app. Contribute to grigio/rails\_rename development by creating an account on GitHub. Per rinominare un progetto basta aggiungere gem ‘rails\_rename’ al Gemfile, bundle install ed eseguire: rake rails:rename[NewAppName] Ciao Luigi
