starting WEBrick from a ruby script

Depending on how WEBrick in invoked I get different results.  If I invoke 
it like "expenses/script/server" and point the browser to <http://
localhost:3000/expenses> I''ll get:

Not Found
`/expenses'' not found.
WEBrick/1.3.1 (Ruby/1.8.6/2007-09-24) at localhost:3000 

However, if I change to the expenses directory and start WEBrick with 
"script/server" I get a different result of:

Routing Error

no route found to match "/expenses" with {:method=>:get}


1.)  why the discrepancy?
2.)  from a ruby script (start_webrick.rb perhaps), how would WEBrick be 
invoked?  Assuming that start_webrick.rb is outside of the "expenses" 
directory created by rails.


Here''s output from WEBrick, if that''s at all useful:

thufir@arrakis ~/rubyCode $ cat expenses.rb 
system("/home/thufir/rubyCode/expenses/script/server")
thufir@arrakis ~/rubyCode $ 


This gives the result of:

Routing Error

no route found to match "/expenses" with {:method=>:get}

from <http://localhost:3000/expenses> which, while not being the desired 
result, is at least consistent :)

Re: starting WEBrick from a ruby script

It''s no doubt a bit kludgy, but I think I accomplished my purpose with:


thufir@arrakis ~/rubyCode $ 
thufir@arrakis ~/rubyCode $ cat railsExpenses.rb 
require ''fileutils''

FileUtils.rmtree ''expenses''

system("rails expenses")

#####   configure the database

FileUtils.rm ''expenses/config/database.yml'', :force => true

database_yml = File.open(''expenses/config/database.yml'',
''w'')

database_yml.puts "
development:
        adapter:        mysql
        database:       expenses_development
        username:       root
        password:
        host:           localhost
        socket:         /var/run/mysqld/mysqld.sock
test:
        adapter:        mysql
        database:       expenses_test
        username:       root
        password:
        host:           localhost
        socket:         /var/run/mysqld/mysqld.sock
production:
        adapter:        mysql
        database:       expenses_production
        username:       root
        password:
        host:           localhost
        socket:         /var/run/mysqld/mysqld.sock"

database_yml.close

#####   migration

system("expenses/script/generate migration accounts")

FileUtils.rm ''expenses/db/migrate/001_accounts.rb'', :force
=> true

_001_accounts =
File.open(''expenses/db/migrate/001_accounts.rb'',
''w'')

_001_accounts.puts "
class Accounts < ActiveRecord::Migration

        def self.up
                create_table :accounts do |table|
                        table.column :name, :string
                        table.column :budget, :float
                end
        end

        def self.down
                drop_table :accounts
        end
end"


_001_accounts.close


#####   rake

FileUtils.cd(''expenses'', :verbose => true)   # chdir and
report it
system("rake db:migrate --trace")


#####   http://localhost:3000/expenses

system("script/server")
thufir@arrakis ~/rubyCode $
