I’ve done these steps before, but am retracing my steps. Now, it generates an error and I’m not sure why. Navigating to \ gives: "Action Controller: Exception caught Unknown action No action responded to index" Which is a bit frustrating because I’ve had it working in the past ☹ (the bash script prints out a copy of itself, if that’s unclear) [thufir@localhost ~]$ [thufir@localhost ~]$ [thufir@localhost ~]$ ./ruby.hello.txt Wed Jun 20 08:59:17 BST 2007 /home/thufir thufir Fedora Core release 6 (Zod) 1 X=0 2 while [$X -le 20] 3 do 4 echo “” 5 X=$((X+1)) 6 done 7 8 9 10 date 11 pwd 12 whoami 13 cat /etc/fedora-release 14 15 cat /home/thufir/ruby.hello.txt -n 16 17 18 rails hello 19 20 ruby /home/thufir/hello/script/generate controller hello 21 22 # Create a file called index.rhtml in app/views/hello, containing “Hello world”. 23 echo “hello world” \> /home/thufir/hello/app/views/hello/ index.html 24 25 echo “[http://localhost:3000/hello](http://localhost:3000/hello)” 26 27 ruby /home/thufir/hello/script/server exists exists app/controllers exists app/helpers exists app/models exists app/views/layouts exists config/environments exists components exists db exists doc exists lib exists lib/tasks exists log exists public/images exists public/javascripts exists public/stylesheets exists script/performance exists script/process exists test/fixtures exists test/functional exists test/integration exists test/mocks/development exists test/mocks/test exists test/unit exists vendor exists vendor/plugins exists tmp/sessions exists tmp/sockets exists tmp/cache exists tmp/pids identical Rakefile identical README identical app/controllers/application.rb identical app/helpers/application\_helper.rb identical test/test\_helper.rb identical config/database.yml identical config/routes.rb identical public/.htaccess identical config/boot.rb identical config/environment.rb identical config/environments/production.rb identical config/environments/development.rb identical config/environments/test.rb identical script/about identical script/breakpointer identical script/console identical script/destroy identical script/generate identical script/performance/benchmarker identical script/performance/profiler identical script/process/reaper identical script/process/spawner identical script/process/inspector identical script/runner identical script/server identical script/plugin overwrite public/dispatch.rb?

Hmm. When I did the following, and went to \<[http://localhost:3000/](http://localhost:3000/) hello\> I did see “hello world” as I wanted. However, I can’t figure out why it works when I type in the commands by hand but not from the bash script. I like the repeatability of the bash script, so want to fix it. I’m looking it over, but any input would be appreciated!

Dear Thufir, In your first script you were echoing “hello world” to index.html. It needs to be index.rhtml. Additionally, your controller needs an index action in it. But I can’t figure out why you are doing this in _SUCH_ a hard way! Try this (with SQLite3 installed as a prerequisite) rails text -d sqlite3 cd text ./script/generate model HelloWorld title:string message:text rake db:migrate ./script/generate scaffold HelloWorld ./script/server And then open your web browser and point to [http://localhost:3001/hello\_worlds/](http://localhost:3001/hello_worlds/) Regards Mikel ---

Boy, it took me about an hour to get it working. I probably looked at that line twenty times and my eye just went right over .html and said “fine”. c’est la vie. > Additionally, your controller needs an index action in it. english please 😉 what does that mean more concretely? > But I can’t figure out why you are doing this in _SUCH_ a hard way! I’m recovering ground with a script because I need it to be repeatable because I’ve run into a wall further down the line. This is a foundation. > Try this (with SQLite3 installed as a prerequisite) > […] The legacy database is MySQL, I have MySQL setup, I like the myPHPAdmin GUI, and, again, the legacy database is using MySQL. The end goal is to get this working with \<[Google Code Archive - Long-term storage for Google Code Project Hosting.](http://code.google.com/p/) feed-on-feeds/ > which is, ironically, a PHP application. The next step is that I have a database “Dummy” with table “Dummy” which I would like listed. I did this before but forgot. Hence, the bash scripts. Then, I’ll move onto the legacy database, some day… -Thufir ---

Get these books (PDF or paper) Four Days on Rails and Agile Web D. with Rails Read them, both books are pretty easy to follow, if you have worked with PHP, Rails shouldn’t be that difficult. For me it was simply terminology. Once I learned how models and controllers worked, everything “just worked” I have seen torrents on tpb and mininova, tho your mileage may vary. ~k On Wed, 2007-06-20 at 12:23 -0700, Thufir wrote: > The next step is that I have a database “Dummy” with table “Dummy” > > > – Kurth Bemis Ozone Computer Consulting, Sales and Service 1 Main Street Springfield, VT 05156 802-885-8030 888-321-OZONE [ozonecomputer.com](http://ozonecomputer.com) ---
