new rails edge project - step by step

I am trying to create a new rails project in edge:

rails campus cd campus rake rails:freeze:edge script/generate model topic title:string body:text rake db:create:all rake db:migrate script/generate controller topics index new create rm public/index.html

I added this line to routes.rb: map.root :controller => "topics"

I type http://localhost:3000 and get this message: Status: 500 Internal Server Error Content-Type: text/html In the development.log I see this: Status: 500 Internal Server Error A secret is required to generate an integrity hash for cookie session data. Use config.action_controller.session = { :session_key => "_myapp_session", :secret => "some secret phrase" } in config/ environment.rb

what am I doing wrong?

Hi Oren :

I am trying to create a new rails project in edge: [..] I type http://localhost:3000 and get this message: Status: 500 Internal Server Error Content-Type: text/html In the development.log I see this: Status: 500 Internal Server Error A secret is required to generate an integrity hash for cookie session data. Use config.action_controller.session = { :session_key => "_myapp_session", :secret => "some secret phrase" } in config/ environment.rb

what am I doing wrong?

Since it's a new Rails project, I would use the edge rails command to create all the skeleton of the app, with the new shiny config/boot.rb the config/initializers dir and so on... and let it create the secret phrase for me.

rails campus_tmp cd campus_tmp rake rails:freeze:edge cd .. ruby campus_tmp/vendor/rails/railties/bin/rails campus mv campus_tmp/vendor/rails campus/vendor/rails rm -Rfv campus_tmp cd campus script/generate model ... # and so on

And in config/environment.rb you will have a correct hash for config.action_controller.session, since Rails generates it for you.

great, it works!

I would like to understand what i just did…

ruby campus_tmp/vendor/rails/railties/bin/rails campus #what’s going on here?

mv campus_tmp/vendor/rails campus/vendor/rails #and here?

rm -Rfv campus_tmp

where can I learn about the edge/rails 2.0? (I am new to rails, just read DHH’s book).

thanks!

We're using the edge version of rails command to generate the campus project, instead of using a 1.2.* version of rails command. So you're sure that the files are up to date with your version (edge) of Rails. And the Rails generator will provide a secret phrase for you in config/environment.rb, so you don't need to create one manually.

mv campus_tmp/vendor/rails campus/vendor/rails #and here?

Well with the previous invocation of rails:freeze:edge task, you've downloaded the edge rails source, there's no use to download it twice, so we've just moved now in the right place, in the campus project structure.

rm -Rfv campus_tmp

We can now remove the temporary campus_tmp project.

where can I learn about the edge/rails 2.0? (I am new to rails, just read DHH's book).

I'm afraid that Rails edge doesn't fit to beginners, since you must have a good knowledge of Rails and Rails internals, to be able to debug on your own.
