Rails - Jan 2005 - Does anyone know what is going on here?

I just got the following feedback posted to my ONLamp.com Rails tutorial. I
haven''t yet tried to duplicate this myself (I just woke up and
I''m getting
ready for work), but no one else reported this. Of course, it likely that no
one else is running Rails 0.9.5 either since it was just released.

I''m going to look at this later today, but any help in the interim
would be
appreciated.

Thanks,
Curt

Hi all,

I can''t say I''ve had the problem that Curt is having, but I am
having
some other problems and I''m running rails 0.9.3 (See earlier posts).

I there some way I use some earlier version? My apologies, I''m 
completely new to ruby/gem/rails, though I am a veteran of LAMP of some 
years.

Oh, I''m using apache 1.3.33 on Mac OS X too.

My current issue is:

Apache config right out of the box with just enough config mods to make 
the server work and support the rails app on port 7000
demo app straight from the tutorial

no modifications to .htaccess

When I hit http://rubyrails:7000/myapp I get the database listing (at 
http://rubyrails/myapp/list#list), but neither the links for new record 
nor edit record work (destroy record works oddly enough); they crash and 
report the following to the browser:


  NoMethodError in Webshots#new

Showing 
//usr/local/lib/ruby/gems/1.8/gems/actionpack-1.3.1/lib/action_controller/templates/rescues//_request_and_response.rhtml/
where line *#3* raised _undefined method `rewrite'' for
#<Url:0x1633404>_

|1: <% if defined?(Breakpoint) %>
2:   <br /><br />
3:   <%= form_tag({:params => {}, :only_path => true},

4:     <input type="hidden" name="BP-RETRY"

5:   
6:     <% for key, values in @params %>
|

Trace of template inclusion:

Thanks for any assistance!

Cheers,
Twitch

I should mention that the first time I did the tutorial, it worked; but 
I was using WEBbrick at that time.

Cheers

I have a logfile (log level 9) from the rewrite rules engine if that 
might help...

Rails is looking for the my_test controller.  MyTest in URL is mapped to
mytest controller, which doesn''t exist.  My_Test works since the URL is
downcased.

I suggest that the dispatcher should call controller_name.underscore
rather than just controller_name.downcase.  Since people do
./script/generate controller MyTest, they expect to see MyTest in URL.

But why is only one user (out of many) who have tried the tutorial run into
this? Is it because he''s using Rails 0.9.5 while all the others were
using
0.9.4?

Maybe this user is the only to try a CamelCased controller name.

I was just able to try this out myself, and its definitely being caused by
Rails 0.9.5.

After creating a controller like this:

  ruby script\generate controller MyTest

and creating an index method inside the controller, these URL fail:

  http://127.0.0.1:3000/mytest/
  http://127.0.0.1:3000/MyTest/

and these URLs work:

  http://127.0.0.1:3000/my_test/
  http://127.0.0.1:3000/My_Test/

I think I''m going to have the editor of ONLamp update the tutorial to
specifically install Rails 0.9.4 -- its going to look bad if users get
inexplicable errors while trying it out. I want things to go smoothly so
that we can entice more developers to come on over from the dark side.

Its definitely caused by changes in Rails 0.9.5. I''m having my tutorial
changed to specifically install Rails 0.9.4.

Curt

The problem I am having is on rails 0.9.4.1. I remain unconvinced that I 
have buggered something up; I''m one of those dark-side developers you 
were mentioning in another post - I''ve been doing cgi on apache, well, 
ever since there was an apache.  Some C form handlers in the early days 
(''94/''95), and then quite a lot of perl since then (I
completely wore
out a camel book and bought a second one).

Is there a way to specify version at rails install time? I''d like 
something different from what I have, even if its just to compare mileage.

Cheers!

To uninstall your current version of rails:

  gem uninstall rails

To install a specific version:

  gem install rails -v <version>

For example:

  gem install rails -v 0.9.3

Thanks Curt.

I just rolled back to 0.9.2 and it had no impact on my issues.

I''m REALLY starting to suspect my webserver config.

This isn''t down to the mod_rewrite in .htaccess, is it?
Do you get the same problem with webrick (./script/server) ?
