Starting WEBrick from a ruby script

Rails
1

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”)

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 :slight_smile:

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”)
