starting WEBrick from a ruby script

rubyonrails-talk
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 $ 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&gt; 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
