I''m currently developing a Rails 2 project that I''d like to
migrate
across to Rail 3. However I''m having real trouble in the first place
getting Rails 3 to work straight out of the box with a blank project.
Initially I tried getting this working a JRuby 1.5 snapshot & then 1.4.
I''ve now been trying the same with Ruby 1.9.1-p378-rc2 from
RubyInstaller with the same results.
The error:
Upon executing "ruby script\rails server" (rails server
doesn''t work in
Windows. Running Win7 btw) I always get the following error...
C:\Users\Phil Ostler\Desktop\Project\Rails>ruby script\rails server
C:/Users/Phil Ostler/Desktop/Project/Rails/config/application.rb:9:in
`<module:Rails>'': superclass mismatch for class Application
(TypeError)
from C:/Users/Phil
Ostler/Desktop/Project/Rails/config/application.rb:8:in `<top
(required)>''
from
C:/Ruby19/lib/ruby/gems/1.9.1/gems/railties-3.0.0.beta/lib/rails/co
mmands.rb:36:in `require''

C:/Ruby19/lib/ruby/gems/1.9.1/gems/railties-3.0.0.beta/lib/rails/co
mmands.rb:36:in `<top (required)>''
from script/rails:10:in `require''
from script/rails:10:in `<main>''
I''ve tried using the latest gems as well as following any guides I
could
find and matching the gem versions they used but always get the same
result.
Current local gem list:
*** LOCAL GEMS ***
abstract (1.0.0)

I''ve googled this and vaguely understand the error but don''t
know how to
go about fixing it. I get the feeling this might not be my setup and
more a gem that''s breaking Rail 3 but that could be miles off the mark.
Any suggestions?
Cheers, Phil

However I''m having real trouble in the first place > getting Rails 3 to work straight out of the box with a blank project. >First a hint. There is a gem named rails3b that somebody in the rails core team created to pull in the missing dependecies of the Rails gem when using the rails 3 beta. Second, Your problem is naming the test application "Rails". That results in a module named "Rails" that contains your application, but the Rails module is part of Rails'' own namespace. Thus your config/application.rb is trying to create or re-open a Rails::Application class that is derived from Rails::Application. I''m not an expert in that corner of Ruby, but I''m not sure tryingg to have a class derive from itself could ever be expected to work. Further Rails::Application is already defined, and it has a different base class, so ruby has no idea what to do, so it spits out an error and stops. Try creating a project with a unique name. You should probably find that works better. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Indeed you are right, changing the name of my application has fixed this. Thank you! Reason for me naming it Rails is because I have separate folders in my project development for different elements (e.g. Rails, Database Schema, Flex) and it always worked in Rails 2 fine for me this way. I''ve used rails3b before but was mix and matching gem versions to try and get around this problem. Now running Ruby 1.9.1-p378-rc2 with Rails 3.0.0.beta2! Next stop, JRuby 1.5.0 dev snapshot...
