1.1 XML to Raw SQLite3

Our store resells products, so lets start with a list of products provided by our supplier. We are ultimately going to want to do things with these products, so lets load them into a database.

Start with some XML, listing a number of products.

edit testdata.xml
<?xml version="1.0" encoding="UTF-8"?>
<products type="array">
  <product>
    <created-at type="datetime">2009-07-05T16:26:31Z</created-at>
    <description>&lt;p&gt;
       &lt;em&gt;Pragmatic Project Automation&lt;/em&gt; shows you how to improve the 
       consistency and repeatability of your project's procedures using 
       automation to reduce risk and errors.
      &lt;/p&gt;
      &lt;p&gt;
        Simply put, we're going to put this thing called a computer to work 
        for you doing the mundane (but important) project stuff. That means 
        you'll have more time and energy to do the really 
        exciting---and difficult---stuff, like writing quality code.

         This book is a recipe-based approach to using Subversion that will 
         get you up and running quickly---and correctly. All projects need
         version control: it's a foundational piece of any project's 
         infrastructure. Yet half of all project teams in the U.S. don't use
         any version control at all. Many others don't use it well, and end 
         up experiencing time-consuming problems.

        Pragmatic programmers use feedback to drive their development and 
        personal processes. The most valuable feedback you can get while 
        coding comes from unit testing.
      &lt;/p&gt;
      &lt;p&gt;
        Without good tests in place, coding can become a frustrating game of 
        "whack-a-mole." That's the carnival game where the player strikes at a 
        mechanical mole; it retreats and another mole pops up on the opposite side 
        of the field. The moles pop up and down so fast that you end up flailing 
        your mallet helplessly as the moles continue to pop up where you least 
        expect them.

</products>

Test that loading the XML produces the right data in the database.

edit test_products.rb
require 'test/unit'
 
class Product_Load_Test < Test::Unit::TestCase
  def setup
    @db = `sqlite3 -line products.db 'select * from products'`
  end
 
  def test_automate
    assert_match /title = Pragmatic Project Automation/, @db
    assert_match /description = <p>\s+<em>Pragmatic Project Automation/, @db
    assert_match %r|image_url = /images/auto.jpg|, @db
    assert_match /price = 24.95/, @db
  end
 
  def test_version
    assert_match /title = Pragmatic Version Control/, @db
    assert_match /description = <p>\s+This book is a recipe-based approach/, @db
    assert_match %r|image_url = /images/svn.jpg|, @db
    assert_match /price = 28.5/, @db
  end
 
  def test_unit
    assert_match /title = Pragmatic Unit Testing/, @db
    assert_match /description = <p>\s+Pragmatic programmers use feedback/, @db
    assert_match %r|image_url = /images/utc.jpg|, @db
    assert_match /price = 27.75/, @db
  end
end

Run that test, watch it fail.

Now write the code that loads the database from XML.

edit load_products.rb
require 'rexml/document'
require 'sqlite3'
 
input  = File.new('testdata.xml')
output = SQLite3::Database.new('products.db')
 
output.execute_batch <<SQL
  CREATE TABLE products (
    id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
    title varchar(255), 
    description text, 
    image_url varchar(255),
    price decimal(8,2) DEFAULT 0
  );
SQL
 
REXML::Document.new(input).each_element('//product') do |product|
  output.execute 'INSERT INTO products(title,description,image_url,price)' +
    ' VALUES (?, ?, ?, ?)',
    product.elements['title'].text,
    product.elements['description'].text,
    product.elements['image-url'].text,
    product.elements['price'].text
end
 
input.close

1.2 Update Using Raw SQLite3

At this point, we could simply just add a DROP TABLE IF EXISTS to the SQL, but that's a wee bit drastic. Over time, we are going to want to add columns (e.g., quantity_on_hand), so lets match products in the database against the contents of the XML by their original ("base") id, and update existing rows if they are already present, adding new rows when they are not.

Conditionally CREATE table, match based on id, and UPDATE when found.

edit load_products.rb
require 'rexml/document'
require 'sqlite3'
 
input  = File.new('testdata.xml')
output = SQLite3::Database.new('products.db')
 
unless output.execute('select name from sqlite_master').include? ["products"]
  output.execute_batch <<-SQL
    CREATE TABLE products (
      id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
      base_id INTEGER,
      title varchar(255), 
      description text, 
      image_url varchar(255),
      price decimal(8,2) DEFAULT 0
    );
  SQL
end
 
REXML::Document.new(input).each_element('//product') do |product|
  title       = product.elements['title'].text
  description = product.elements['description'].text
  image_url   = product.elements['image-url'].text
  price       = product.elements['price'].text
 
  base_id     = product.elements['id'].text
 
  id = output.execute('SELECT id FROM products WHERE base_id=?', base_id)
  if id.empty?
    output.execute 'INSERT INTO products' +
      '(base_id, title, description, image_url, price)' +
      ' VALUES (?, ?, ?, ?, ?)', base_id, title, description, image_url, price
  else
    output.execute 'UPDATE products ' +
      'SET base_id=?, title=?, description=?, image_url=?, price=? WHERE id=?',
      base_id, title, description, image_url, price, id.first
  end
end
 
input.close
output.close

Run the same test as before.

ruby load_products.rb
/usr/lib/ruby/1.8/sqlite3/errors.rb:62:in `check': no such column: base_id (SQLite3::SQLException)
	from /usr/lib/ruby/1.8/sqlite3/statement.rb:39:in `initialize'
	from /usr/lib/ruby/1.8/sqlite3/database.rb:154:in `new'

	from /usr/lib/ruby/1.8/rexml/element.rb:393:in `each_element'
	from load_products.rb:20

1.3 Update Using ActiveRecord

Our code is SQLite3 specific (for deployment, we might prefer MySQL or Oracle or DB2...), and is starting to get crufty. Let's see if ActiveRecord can simplify things.

establish_connection, Schema.define, find_by_base_id, save!

edit load_products.rb
require 'rexml/document'
require 'rubygems'
require 'active_record'
 
input  = File.new('testdata.xml')
 
ActiveRecord::Base.establish_connection(
  :adapter => 'sqlite3',
  :database => 'products.db')
 
class Product < ActiveRecord::Base
  unless table_exists?
    ActiveRecord::Schema.define do
      create_table :products do |t|
        t.integer :base_id
        t.string  :title
        t.text    :description
        t.string  :image_url
        t.decimal :price, :precision=>8, :scale=>2, :default=>0.0
      end
    end
  end
end
 
REXML::Document.new(input).each_element('//product') do |xproduct|
  base_id  = xproduct.elements['id'].text
 
  product = Product.find_by_base_id(base_id) || Product.new 
 
  product.base_id     = base_id
  product.title       = xproduct.elements['title'].text
  product.description = xproduct.elements['description'].text
  product.image_url   = xproduct.elements['image-url'].text
  product.price       = xproduct.elements['price'].text
 
  product.save!
end

    load via raw SQLite3

2.1 Rack

Now, lets get that data to display in the brower, using the simplest thing that could possibly work, namely Rack.

Tests: response OK, 3 products, and verify one title.

edit test_product_server.rb
require 'product_server'
require 'test/unit'
require 'rack/test'
 
class ProductServerTest < Test::Unit::TestCase
  include Rack::Test::Methods
 
  def app
    ProductServer.new
  end
 
  def test_product_list
    response = get('/products')
    assert response.ok?
    assert 3, response.body.scan('<h2>').count
    assert_match /<h2>Pragmatic Project Automation<\/h2>/, response.body
  end
end

Code: Establish connection, use Builder, and send response.

edit product_server.rb
require 'rubygems'
require 'rack'
require 'builder'
require 'active_record'
 
ActiveRecord::Base.establish_connection(
  :adapter => 'sqlite3',
  :database => 'products.db')
 
class Product < ActiveRecord::Base
end
 
class ProductServer
  def call(env)
    x = Builder::XmlMarkup.new :indent=>2
 
    x.html do
      x.head do
        x.title 'Pragmatic Bookshelf'
      end
      x.body do
        x.h1 'Pragmatic Bookshelf'
 
        Product.all.each do |product|
          x.h2 product.title
          x << "      #{product.description}\n"
          x.p product.price
        end
      end
    end
 
    response = Rack::Response.new
    response['Content-Type'] = 'text/html'
    response.write x.target!
    response.finish
  end
end

        mechanical mole; it retreats and another mole pops up on the opposite side 
        of the field. The moles pop up and down so fast that you end up flailing 
        your mallet helplessly as the moles continue to pop up where you least 
        expect them.

2.2 Capistrano

We've got the program working on our machine, let's deploy it to our server machine which is running Passenger (a.k.a. mod_rails a.k.a. mod_rack) on Apache's http. This takes a bit of planning the first time, but then Capistrano takes all of the guesswork and potential for errors out of the equation when it really matters. Note: this step can be safely skipped on first reading.

Create our Capistrano configuration

capify .
[skip] `./Capfile' already exists
[add] writing `./Capfile'
[add] writing `./config/deploy.rb'
[done] capified!

Tailor it extensively

edit config/deploy.rb
# be sure to change these
set :user, 'sa3ruby'
set :domain, 'depot.intertwingly.net'
set :application, 'depot'
 
# file paths
set :repository,  "#{user}@#{domain}:git/#{application}.git" 
set :deploy_to, "/home/#{user}/#{domain}" 
 
# distribute your applications across servers (the instructions below put them
# all on the same server, defined above as 'domain', adjust as necessary)
role :app, domain
role :web, domain
role :db, domain, :primary => true
 
# you might need to set this if you aren't seeing password prompts
default_run_options[:pty] = true
 
# As Capistrano executes in a non-interactive mode and therefore doesn't cause
# any of your shell profile scripts to be run, the following might be needed
# if (for example) you have locally installed gems or applications.  Note:
# this needs to contain the full values for the variables set, not simply
# the deltas.
default_environment['PATH']='$HOME/.gems/bin:/usr/local/bin:/usr/bin:/bin'
default_environment['GEM_PATH']='$HOME/.gems:/usr/lib/ruby/gems/1.8'
 
# miscellaneous options
set :deploy_via, :remote_cache
set :scm, 'git'
set :branch, 'master'
set :scm_verbose, true
set :use_sudo, false
 
# additional tasks
namespace :deploy do
  desc 'Restarting Passenger'
  task :restart, :roles => :app do
    run "mkdir -p #{current_path}/tmp" 
    run "touch #{current_path}/tmp/restart.txt" 
  end
end
 
# insert tasks into the deployment sequence
after "deploy:symlink", "deploy:restart"

Pragmatic Project Automation

Pragmatic Project Automation shows you how to improve the consistency and repeatability of your project's procedures using automation to reduce risk and errors.

Simply put, we're going to put this thing called a computer to work for you doing the mundane (but important) project stuff. That means you'll have more time and energy to do the really exciting---and difficult---stuff, like writing quality code.

24.95

Pragmatic Version Control

This book is a recipe-based approach to using Subversion that will get you up and running quickly---and correctly. All projects need version control: it's a foundational piece of any project's infrastructure. Yet half of all project teams in the U.S. don't use any version control at all. Many others don't use it well, and end up experiencing time-consuming problems.

28.5

Pragmatic Unit Testing (C#)

Pragmatic programmers use feedback to drive their development and personal processes. The most valuable feedback you can get while coding comes from unit testing.

Without good tests in place, coding can become a frustrating game of "whack-a-mole." That's the carnival game where the player strikes at a mechanical mole; it retreats and another mole pops up on the opposite side of the field. The moles pop up and down so fast that you end up flailing your mallet helplessly as the moles continue to pop up where you least expect them.

3.1 Convert to Rails

Taking a step back, we have done something real. It doesn't do much, but it didn't really take much code either. But the problems are starting to accumulate: our application directory is getting cluttered, changes to schemas is a problem, we have code duplicated that establishes the connection, and we haven't even begun thinking about updates. Additionally, we have the database in the git repository and while that has proven to be convenient so far, that won't be such a hot idea once we deploy. And synchronizing gems versions between the machines is a pain... Fred Brooks once recommended that we "plan to throw one away; you will, anyhow." As you will see, we are not exactly going to be throwing anything away, but we will be in a very real sense starting over.

First, let Rails do its thing...

    Pragmatic Project Automation
    <p>
       <em>Pragmatic Project Automation</em> shows you how to improve the 
       consistency and repeatability of your project's procedures using 
       automation to reduce risk and errors.
      </p>
      <p>
        Simply put, we're going to put this thing called a computer to work 
        for you doing the mundane (but important) project stuff. That means 
        you'll have more time and energy to do the really 
        exciting---and difficult---stuff, like writing quality code.

    Pragmatic Version Control
    <p>
         This book is a recipe-based approach to using Subversion that will 
         get you up and running quickly---and correctly. All projects need
         version control: it's a foundational piece of any project's 
         infrastructure. Yet half of all project teams in the U.S. don't use
         any version control at all. Many others don't use it well, and end 
         up experiencing time-consuming problems.

        personal processes. The most valuable feedback you can get while 
        coding comes from unit testing.
      </p>
      <p>
        Without good tests in place, coding can become a frustrating game of 
        "whack-a-mole." That's the carnival game where the player strikes at a 
        mechanical mole; it retreats and another mole pops up on the opposite side 
        of the field. The moles pop up and down so fast that you end up flailing 
        your mallet helplessly as the moles continue to pop up where you least 
        expect them.

  Title:
  Pragmatic Project Automation





  Description:
  <p>
       <em>Pragmatic Project Automation</em> shows you how to improve the 
       consistency and repeatability of your project's procedures using 
       automation to reduce risk and errors.
      </p>
      <p>
        Simply put, we're going to put this thing called a computer to work 
        for you doing the mundane (but important) project stuff. That means 
        you'll have more time and energy to do the really 
        exciting---and difficult---stuff, like writing quality code.

3.2 Deploy Rails

    
    
Capistrano is understands Rails, but there are a few things you need to be aware of.

    
Update whenever to use runner.

    
edit config/schedule.rb

    
# Use this file to easily define all of your cron jobs.

    
#

    
# It's helpful, but not entirely necessary to understand cron before proceeding.

    
# http://en.wikipedia.org/wiki/Cron

    
 

    
# Example:

    
#

    
# set :cron_log, "/path/to/my/cron_log.log"

    
#

    
# every 2.hours do

    
#   command "/usr/bin/some_great_command"

    
#   runner "MyModel.some_method"

    
#   rake "some:great:rake:task"

    
# end

    
#

    
# every 4.days do

    
#   runner "AnotherModel.prune_old_records"

    
# end

    
 

    
# Learn more: http://github.com/javan/whenever

    
 

    
every 1.day, :at => '4:15 am' do

    
  runner "Product.import('http://depot.intertwingly.net/testdata.xml')"

    
end

    
Peek at the results.

    
whenever

    
15 4 * * * /home/rubys/git/awdwr/work/depot/script/runner -e production "Product.import('http://depot.intertwingly.net/testdata.xml')"

    
 

    
Add GEM_HOME to environment.rb, migration tasks, and do cleanup.

    
edit config/deploy.rb

    
# be sure to change these

    
set :user, 'sa3ruby'

default_run_options[:pty] = true

    
 

    
# As Capistrano executes in a non-interactive mode and therefore doesn't cause

    
# any of your shell profile scripts to be run, the following might be needed

    
# if (for example) you have locally installed gems or applications.  Note:

    
# this needs to contain the full values for the variables set, not simply

    
# the deltas.
