Just spent some time setting up Rails 3.0 on my machine. With some
help from wycats, I was able to get things going.
You're probably aware of this, but in order for railties/bin/rails to
work, I had to run
ruby -rubygems rails-master/railties/bin/rails MasterApp
Without -rubygems, action_dispatch complained about not being able to
locate 'rack', in actionpack/lib/action_dispatch.rb line 28.
Also, in order to bundle Rails 3 from edge, I couldn't just uncomment
the line in Gemfile. I also needed to bundle arel and rack before it.
I guess rack has changes that haven't made it up stream yet, and arel
gem wasn't pushed to gemcutter?
gem 'rack', '1.0.1', :git => 'git://github.com/rails/rack.git'
gem 'arel', :git => 'git://github.com/rails/arel.git'
gem "rails", :git => "git://github.com/rails/rails.git"
Anyway, once it bundled and run fine, the first thing I noticed was
and error when clicking on "About your application’s environment".
ActionController::RoutingError (No route matches "/rails/info/
I went into routes.rb, uncommented the last line (the catch all
route), and it started working.
Other than that, no issues so far with scaffolding or adding objects
via web interface.
