[http://localhost:3000/hello/world](http://localhost:3000/hello/world) gives: "Unknown action No action responded to world" I’m following along with \<[http://wiki.rubyonrails.org/rails/pages/](http://wiki.rubyonrails.org/rails/pages/) Tutorial\> and what stands out are statements like: “Now take a look at app/controllers/hello\_controller.rb.” Which doesn’t exist for me, I had to create multiple directories. I would’ve thought that a directory like “controllers” would be pre- existing? Anyhow, I was getting: "Hello#index Find me in app/views/hello/index.rhtml" from both [http://localhost:3000/hello](http://localhost:3000/hello) and \<[http://localhost:3000/hello/](http://localhost:3000/hello/) index\>, but seem to have lost the thread of the tutorial. I know that my .rhtml file should be using the variable which is defined elsewhere, but it’s not clear from this tutorial how to do that (entirely). It doesn’t specify what each file should look like in its entirety, and I, for instance, can’t follow the instruction to “Notice the index function,” because there’s no such function in the file which I created. Should I create such a function? No doubt, but the discrepancy indicates that perhaps my configuration is mucked up. The index function should’ve been created by…? In any event, here’s my decidedly primitive script which I’m using to run my ruby stuff, and it’s output: [thufir@localhost dummy]$ [thufir@localhost dummy]$ [thufir@localhost dummy]$ pwd /home/thufir/dummy [thufir@localhost dummy]$ ll total 140 drwxrwxr-x 6 thufir thufir 4096 May 13 04:15 app drwxrwxr-x 2 thufir thufir 4096 May 13 04:15 components drwxrwxr-x 3 thufir thufir 4096 May 16 06:06 config drwxrwxr-x 2 thufir thufir 4096 May 16 19:42 controllers drwxrwxr-x 2 thufir thufir 4096 May 13 04:15 db drwxrwxr-x 2 thufir thufir 4096 May 13 04:15 doc drwxrwxr-x 3 thufir thufir 4096 May 13 04:15 lib drwxrwxr-x 2 thufir thufir 4096 May 13 04:15 log drwxrwxr-x 5 thufir thufir 4096 May 13 04:15 public -rw-rw-r-- 1 thufir thufir 307 May 13 04:15 Rakefile -rw-rw-r-- 1 thufir thufir 8001 May 13 04:15 README -rwxrwxr-x 1 thufir thufir 307 May 16 19:49 run drwxrwxr-x 4 thufir thufir 4096 May 13 04:15 script drwxrwxr-x 7 thufir thufir 4096 May 13 04:15 test drwxrwxr-x 6 thufir thufir 4096 May 13 04:15 tmp drwxrwxr-x 3 thufir thufir 4096 May 13 04:15 vendor drwxrwxr-x 3 thufir thufir 4096 May 16 19:29 views [thufir@localhost dummy]$ [thufir@localhost dummy]$ cat run ruby script/generate scaffold dummy ; ./script/generate controller hello index ; cat /home/thufir/dummy/views/hello/world.rhtml ; cat /home/thufir/ dummy/config/database.yml ; cat /home/thufir/dummy/controllers/ hello\_controller.rb ; cat /home/thufir/dummy/views/hello/world.rhtml ; date ; ./script/server [thufir@localhost dummy]$ [thufir@localhost dummy]$ ./run exists app/controllers/ exists app/helpers/ exists app/views/dummies exists app/views/layouts/ exists test/functional/ dependency model exists app/models/ exists test/unit/ exists test/fixtures/ identical app/models/dummy.rb identical test/unit/dummy\_test.rb identical test/fixtures/dummies.yml identical app/views/dummies/\_form.rhtml identical app/views/dummies/list.rhtml identical app/views/dummies/show.rhtml identical app/views/dummies/new.rhtml identical app/views/dummies/edit.rhtml identical app/controllers/dummies\_controller.rb identical test/functional/dummies\_controller\_test.rb identical app/helpers/dummies\_helper.rb identical app/views/layouts/dummies.rhtml identical public/stylesheets/scaffold.css exists app/controllers/ exists app/helpers/ exists app/views/hello exists test/functional/ identical app/controllers/hello\_controller.rb identical test/functional/hello\_controller\_test.rb identical app/helpers/hello\_helper.rb identical app/views/hello/index.rhtml aaaaaaargh # MySQL (default setup).
