Blank pages, 'missing default helper path rails_info_helper'

Rails
1

Environment:

  • OS X 10.4.3
  • Ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]
  • Rails (1.0.0, 0.13.1)
  • WEBrick 1.3.1
  • Following the wiki directions, I did the OSX fixrbconfig thing,
    installed Rails, MySQL, etc…

Please bear with me, I’m new to Rails.

I successfully followed the ‘depot’ application from the Agile Web
Development with Rails book, building it piece by piece with no
problems.

I then went to start a new Rails project in a clean empty directory
using the command ‘rails testing’ without problems. When I started the
server, I could access the default index page, but nothing else would
work. Not even the “About your application’s environment link” on the
index page.

Worse, any page I accessed besides the default index page results in no
data/blank page, and WEBrick entry that looks like:

127.0.0.1 - - [28/Dec/2005:23:00:46 EST] “GET /aaa HTTP/1.1” 500
0

That happens no matter which URL I access, including a controller/action
I built, a controller that doesn’t exist, and like I mentioned, the
/rails_info/properties that’s called on the “About your application’s
environment link.”

I’ve tried deleting my Rails project, recreating it, creating some
controllers, scaffolding, etc… tried copying my working
config/databases.yml to config/, etc. Absolutely no difference.

And yet if I go back to my depot directory and start the server, that
one still works perfectly.

I haven’t changed anything since I first built the depot app a few days
ago. I can’t think of what’s going on. Any ideas? I’m dying to build
more stuff.

Oops, assumed Textile formatting.

One thing I forgot to mention. The only logged error I do see is this
one when trying to access in environment-link on the default index page:

Controllers::RailsInfoController: missing default helper path
rails_info_helper

No other errors get logged. I even tried to add a controller with a
corresponding action that did logger.error(“testing”), but that didn’t
get logged.

Weird, huh?

Never mind. Found this in today’s IRC log:

[06:41] <purestorm_> Does anyone have an idea why webrick is launching
RoR with 1.0 rails? I’m trying to access http://127.0.0.1:3000/foobar on
a fresh rails application (read: foobar is not valid) and I get blank
pages. I’m on Os X and have ruby 1.8.2
…
[06:44] <purestorm_> I removed /tmp/ruby_sess*
[06:44] <purestorm_> and it works … strange

Hi,

Maybe try clearing the sessions? rm /tmp/ruby_sess*
