MissingSourceFile in Rails/infoController#properties

Rails
1

I am having a very similar problem to a post I read and replied to. I
am reading ‘Build your own Ruby on Rails web applications’ by Patrick
Lenz and when accessing http://localhost:3000/ I can connect to the
application. But when I click “about your application environment” I
receive this error: MissingSourceFile in Rails/
infoController#properties

I think it is booting up completely as this is what I see:
=> Booting Mongrel <use ‘script/server webrick’ to force WEBrick>
=> Rails applicatino starting on http://0.0.0.0:3000
=> Calls with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000
** Starting Rails with development environment…
** Rails loaded
** Loading any Rails specific GemPlugins
** Singals ready. INT => stop .
** Mongrel available at 0.0.0.0:3000
** Use CTRL-C to stop

That’s it, no prompt after this. I did see a threat stating to change
infoController to InfoController but alas, I’m not sure how to do
that! Any help would be greatly appreciated, I am excited to get
started. Thanks.

Don’t know if you have already resolved this issue. As someone above
suggested, its definitely related to sqlite/sqlite3 (which is not
required for OS-X, but definitely must be setup for Windows
environment). The mentioned approach “gem install sqlite-ruby/sqlite3-
ruby” doesn’t work for some reason (gave me sqlite3.dll error) and you
may have to find some other ways of installing it on your machine.
I didn’t try sqlite fix since my requirements were to use MySQL. Here
is a two cent on what I did to fix the issue.

  1. Installed MySQL and HeidiSQL following steps mentioned in pages 1
    and 2 from a tutorial provided here
    Radar – O’Reilly
  2. Created a dummy database called test with a table and few fields
    and saved it under E:\rails_apps\app_name\db where app_name = “your
    app name that you created using “rails app_name” command”
  3. database.yml under E:\rails_apps\app_name\config folder modified
    for development. Other environments were commented out.
    development:
    adapter: mysql
    database: test
    host: localhost
    username: root
    password: xxxxx <= Password that you set during MySQL install
  4. After this restart the mongrel server, hit localhost at 3000 and
    click on the link … it should give you information like the one
    posted below.
    Ruby version 1.8.6 (i386-mswin32)
    RubyGems version 0.9.4
    Rails version 2.0.2
    Active Record version 2.0.2
    Action Pack version 2.0.2
    Active Resource version 2.0.2
    Action Mailer version 2.0.2
    Active Support version 2.0.2
    Application root E:/rails_apps/app_name
    Environment development
    Database adapter mysql

FYI, I used the defailt WEBrick server, however it should work the
same for Mongrel.

Although I have digressed from the original issue, it should be the
similar for sqlite. Good luck!!!
