I''m a Rails newbie (and a Ruby newbie for that matter). I am working
my way through the book href="http://www.amazon.com/Simply-Rails-2-
Patrick-Lenz/dp/0980455200/ref=sr_1_1?
ie=UTF8&s=books&qid=1247152951&sr=8-1">"Simply Rails
2"</a>.
I have generated the model and controller parts of the sample app, at
which point the author instructs the reader to start the web server
and view the app with their browser.
Viewing http://localhost:3000/stories in my browser should display the
file app/views/stories/index.html.erb, but instead displays the
following error:
Status: 500 Internal Server Error Content-Type: text/html
500 Internal Server Error
Any ideas what might be causing this error?
Please see the partial output from the server below:
=> Booting Mongrel (use ''script/server webrick'' to force
WEBrick)
=> Rails application starting on http://0.0.0.0:3000
=> Call with -d to detach

Use config.action_controller.session = { :session_key => > "_myapp_session", :secret => "some secret phrase of at least 30 > characters" } in config/environment.rbWell, it''s telling you how to fix it. You need to put something like config.action_controller.session = { :session_key = "-myapp_session", # where myapp should be the name of your application instead of myap :secret => "Some Random String at least 30 characters long, usually a long hexadecimal string" } somewhere inside the intializer block (which begins with) Rails::Initializer.run do |config| inside config/environment.rb You can and probably should use rake secret to generate the secret. -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Twitter: http://twitter.com/RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale
Thanks guys. I generated the secret string using rake secret and added the code to config/environment.rb and that error has now disappeared. It seems the error came about because I started coding the app under Rails 1.2.6 and then upgraded to Rails 2.0.2 to be in line with the version used by the Simply Rails 2 book. As a newbie I don''t fully understand what rake can be used for, but I''m sure I''ll learn soon enough. Thanks again.

I *strongly* recommens that you use that to learn on, not 2.0.2.> > As a newbie I don''t fully understand what rake can be used for, but > I''m sure I''ll learn soon enough.Rake is designed to automate tasks. As you work with Rails, you will find that there are many common maintenance tasks that are generally automated by Rake (type "rake -T" for a list).> > Thanks again.Best, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/.
