From: jl_post@... Date: 2005-11-17T08:37:18+09:00 Subject: Help needed with Ruby on Rails Dear Ruby community, I need some help (hopefully just a little) installing and using Ruby on Rails. I'm fairly new to both Ruby and Rails, so I am following the steps mentioned in the book "Agile Web Development with Rails" (by Dave Thomas and David Heinemeier Hansson). Currently, I am going through the steps of "Chapter 4: Instant Gratification". I got to the point where I type "ruby script/server", then connect to http://mylocalsite.local.net:3000/ and then see a nice "Congratulations, you've put Ruby on Rails!" welcome message. So far so good. In fact, On the WEBrick server side, I can see these four lines when I try to visit that page (using a web browser): 192.168.1.222 - - [16/Nov/2005:15:38:11 MST] "GET / HTTP/1.1" 304 0 - -> / 192.168.1.222 - - [16/Nov/2005:15:38:11 MST] "GET /favicon.ico HTTP/1.1" 304 0 - -> /favicon.ico Okay, so now I run the command "ruby script/generate controller Say" from the command line to create a controller called "say" (just like the example in the book). It seems to work correctly -- that is, the directory structure appears to be there as well as the app/controllers/say_controller.rb file. I even edited the SayController class to be: class SayController < ApplicationController def hello end end Here's where things go wrong: When I try to visit http://mylocalsite.local.net:3000/say/hello I get a blank screen on my web browser. I get no error message or anything. According to the book, I should see a "Template is missing" error message, but instead I see nothing at all. (This even happens if I stop and restart the WEBrick server.) I even tried creating the file app/views/say/hello.rhtml (that all it says is "Hello from Rails!") but when I reload the page, I still get nothing. I should at least get an error message, right? So now I'm not sure what to do. So far I've installed Rails two times (to make sure I didn't miss a step) but I still get the same error. In case anyone's interested, my version of Ruby is 1.8.2 and my version of rubygems is 0.8.11 (running on Debian Linux). I captured the output of the WEBrick server in case anyone wants to see it. First a connection is make to http://mylocalsite.local.net:3000/ is made (where everything looks fine) and then a connection to http://mylocalsite.local.net:3000/say/hello is made (where the entire page is blank). It looks like I'm missing a source file of some sort, but which one? Did I not install gem correctly? Did I not use gem to install Rails correctly? I'm not sure how to read the error output of the server to figure out how to correct my problem. Any help would be appreciated. I tried to give as much information as I thought would help, but if some is missing, let me know and I'll try to post it. Thank you very much for any help.
