Ruby on rails problem - We're sorry, but something went wrong (500) please help

Try using this command on the command line: rake secret

Thank you! I got the random # now. But now when i run the server I get this:

You did not specify how you would like Rails to report deprecation notices for y our development environment, please set config.active_support.deprecation to :lo g at config/environments/development.rb SECURITY WARNING: No secret option provided to Rack::Session::Cookie. This poses a security threat. It is strongly recommended that you provide a secret to prevent exploits that may be possible from crafted cookies.

Thanks! Dave

I'm pretty confused and this is frustrating. Again, when I go to 127.0.0.1:3000 it gives me the same ArgumentError about security! Oh boy!

Hi David,

Can you zip up your treebook project and email it to help@teamtreehouse.com? That will help me to troubleshoot the error.

Thank you Jason! I sent it over to you.

I'm getting the same error on Ubuntu 12.04. I know there are differences and I've been able to adapt to most of them (even the REALLY annoying failure of rails server to shut down using Ctrl-C), but I'm stuck on not being able to see the /statuses page.

http://127.0.0.1:3000 looks fine, http://127.0.0.1:3000/statuses gives me a "We're sorry, but something went wrong." error page, which after a little digging is in the 500.html page. I get the same error when I click on the "About your application's environment" link on the main "Welcome Aboard" page.

When I run "rake secret", as suggested above, I get bunch of Gem deprecation notices: "NOTE: Gem.source_index is deprecated, use Specification. It will be removed on or after 2011-11-01.

I suspect I am missing an update to gems, but apt-get tells me I have the latest update. I had to jump through a bunch of hoops to get RVM to install, but at last it did without errors.

Any help would be greatly appreciated!

Hey Rob,

The versions of Ruby and gems that Ubuntu uses are generally waaaay out of date. You'll need to install them with rvm and modify your path to use rvm instead. You can also uninstall the system Ruby libraries. It's a bit of a pain. Once you do all that then run bundle install again to get the latest versions.

Jason thanks very much!

I basically removed all the ruby, rvm, gem and rails packages with apt-get, then went to the rvm.io site, loaded it with their instructions, then loaded rubygems and rails, rebuilt the project (which incidentally allowed me to use "rails new treebook" to build it rather than "rails treebook" as well as "rails server" rather than "script/server" and "script generate"

I was seriously about to jettison Ubuntu and load a different distro!
