app/views/demo/fact_list.rhtml app/views/layouts/demo.rhtml @@ -1,183 +1,3 @@ -== Welcome to Rails +== Welcome to ActiveWarehouse Demo -Rails is a web-application and persistence framework that includes everything -needed to create database-backed web-applications according to the -Model-View-Control pattern of separation. This pattern splits the view (also -called the presentation) into "dumb" templates that are primarily responsible -for inserting pre-built data in between HTML tags. The model contains the -"smart" domain objects (such as Account, Product, Person, Post) that holds all -the business logic and knows how to persist themselves to a database. The -controller handles the incoming requests (such as Save New Account, Update -Product, Show Post) by manipulating the model and directing data to the view. - -In Rails, the model is handled by what's called an object-relational mapping -layer entitled Active Record. This layer allows you to present the data from -database rows as objects and embellish these data objects with business logic -methods. You can read more about Active Record in -link:files/vendor/rails/activerecord/README.html. - -The controller and view are handled by the Action Pack, which handles both -layers by its two parts: Action View and Action Controller. These two layers -are bundled in a single package due to their heavy interdependence. This is -unlike the relationship between the Active Record and Action Pack that is much -more separate. Each of these packages can be used independently outside of -Rails. You can read more about Action Pack in -link:files/vendor/rails/actionpack/README.html. - - -== Getting started - -1. Start the web server: <tt>ruby script/server</tt> (run with --help for options) -2. Go to http://localhost:3000/ and get "Welcome aboard: You’re riding the Rails!" -3. Follow the guidelines to start developing your application - - -== Web servers - -Rails uses the built-in web server in Ruby called WEBrick by default, so you don't -have to install or configure anything to play around. - -If you have lighttpd installed, though, it'll be used instead when running script/server. -It's considerably faster than WEBrick and suited for production use, but requires additional -installation and currently only works well on OS X/Unix (Windows users are encouraged -to start with WEBrick). We recommend version 1.4.11 and higher. You can download it from -http://www.lighttpd.net. - -If you want something that's halfway between WEBrick and lighttpd, we heartily recommend -Mongrel. It's a Ruby-based web server with a C-component (so it requires compilation) that -also works very well with Windows. See more at http://mongrel.rubyforge.org/. - -But of course its also possible to run Rails with the premiere open source web server Apache. -To get decent performance, though, you'll need to install FastCGI. For Apache 1.3, you want -to use mod_fastcgi. For Apache 2.0+, you want to use mod_fcgid. - -See http://wiki.rubyonrails.com/rails/pages/FastCGI for more information on FastCGI. - -== Example for Apache conf - - <VirtualHost *:80> - ServerName rails - DocumentRoot /path/application/public/ - ErrorLog /path/application/log/server.log - - <Directory /path/application/public/> - Options ExecCGI FollowSymLinks - AllowOverride all - Allow from all - Order allow,deny - </Directory> - </VirtualHost> - -NOTE: Be sure that CGIs can be executed in that directory as well. So ExecCGI -should be on and ".cgi" should respond. All requests from 127.0.0.1 go -through CGI, so no Apache restart is necessary for changes. All other requests -go through FCGI (or mod_ruby), which requires a restart to show changes. - - -== Debugging Rails - -Have "tail -f" commands running on both the server.log, production.log, and -test.log files. Rails will automatically display debugging and runtime -information to these files. Debugging info will also be shown in the browser -on requests from 127.0.0.1. - - -== Breakpoints - -Breakpoint support is available through the script/breakpointer client. This -means that you can break out of execution at any point in the code, investigate -and change the model, AND then resume execution! Example: - - class WeblogController < ActionController::Base - def index - @posts = Post.find_all - breakpoint "Breaking out from the list" - end - end - -So the controller will accept the action, run the first line, then present you -with a IRB prompt in the breakpointer window. Here you can do things like: - -Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint' - - >> @posts.inspect - => "[#<Post:0x14a6be8 @attributes={\"title\"=>nil, \"body\"=>nil, \"id\"=>\"1\"}>, - #<Post:0x14a6620 @attributes={\"title\"=>\"Rails you know!\", \"body\"=>\"Only ten..\", \"id\"=>\"2\"}>]" - >> @posts.first.title = "hello from a breakpoint" - => "hello from a breakpoint" - -...and even better is that you can examine how your runtime objects actually work: - - >> f = @posts.first - => #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}> - >> f. - Display all 152 possibilities? (y or n) - -Finally, when you're ready to resume execution, you press CTRL-D - - -== Console - -You can interact with the domain model by starting the console through script/console. -Here you'll have all parts of the application configured, just like it is when the -application is running. You can inspect domain models, change values, and save to the -database. Starting the script without arguments will launch it in the development environment. -Passing an argument will specify a different environment, like <tt>script/console production</tt>. - -To reload your controllers and models after launching the console run <tt>reload!</tt> - - - -== Description of contents - -app - Holds all the code that's specific to this particular application. - -app/controllers - Holds controllers that should be named like weblog_controller.rb for - automated URL mapping. All controllers should descend from - ActionController::Base. - -app/models - Holds models that should be named like post.rb. - Most models will descend from ActiveRecord::Base. - -app/views - Holds the template files for the view that should be named like - weblog/index.rhtml for the WeblogController#index action. All views use eRuby - syntax. This directory can also be used to keep stylesheets, images, and so on - that can be symlinked to public. - -app/helpers - Holds view helpers that should be named like weblog_helper.rb. - -app/apis - Holds API classes for web services. - -config - Configuration files for the Rails environment, the routing map, the database, and other dependencies. - -components - Self-contained mini-applications that can bundle together controllers, models, and views. - -db - Contains the database schema in schema.rb. db/migrate contains all - the sequence of Migrations for your schema. - -lib - Application specific libraries. Basically, any kind of custom code that doesn't - belong under controllers, models, or helpers. This directory is in the load path. - -public - The directory available for the web server. Contains subdirectories for images, stylesheets, - and javascripts. Also contains the dispatchers and the default HTML files. - -script - Helper scripts for automation and generation. - -test - Unit and functional tests along with fixtures. - -vendor - External libraries that the application depends on. Also includes the plugins subdirectory. - This directory is in the load path. +This is a demo for the ActiveWarehouse plugin. \ No newline at end of file README @@ -1,5 +1,13 @@ class DemoController < ApplicationController def index + render :action => "demo/index", :layout => "application" + end + def example1 + + end + def fact_list + @facts = PosRetailSalesTransactionFact.find( + :all, :include => [:date, :store]) end end app/controllers/demo_controller.rb @@ -1,4 +1,6 @@ class PosRetailSalesTransactionFact < ActiveWarehouse::Fact define_aggregate :sales_quantity, :type => :sum define_aggregate :sales_dollar_amount, :type => :sum + belongs_to :date, :foreign_key => 'date_id', :class_name => 'DateDimension' + belongs_to :store, :foreign_key => 'store_id', :class_name => 'StoreDimension' end \ No newline at end of file app/models/pos_retail_sales_transaction_fact.rb @@ -13,5 +13,8 @@ <%= image_tag 'example1-erd.png', :alt => 'Example 1 ERD Diagram' %> <p><%= link_to 'Example #1', :action => 'example1' %></p> </li> + <li> + <h2>Fact List</h2> + <p><%= link_to 'Fact List', :action => 'fact_list' %></p> </ol> </div> \ No newline at end of file app/views/demo/index.rhtml @@ -7,7 +7,9 @@ facts = [ [300, 3, 1, 1, 'ABC000000002', 1, 1.34, 0.72], [600, 3, 1, 1, 'ABC000000003', 2, 2.68, 1.44], [1800, 3, 1, 1, 'ABC000000004', 1, 1.34, 0.72], - [1, 1, 1, 1, 'DEF000000001', 3, 3.45, 1.56], + [1800, 2, 1, 1, 'ABC000000005', 1, 0.94, 0.34], + [1801, 1, 1, 1, 'ABC000000006', 2, 2.68, 1.44], + [1, 1, 2, 1, 'DEF000000001', 3, 3.45, 1.56], [300, 3, 2, 1, 'DEF000000002', 1, 1.34, 0.72], [600, 3, 2, 1, 'DEF000000003', 2, 2.68, 1.44], [1800, 3, 2, 1, 'DEF000000004', 1, 1.34, 0.72] db/setup/pos_retail_sales_transaction.rb @@ -8,4 +8,6 @@ select d2.store_name, sum(f.sales_quantity) from pos_retail_sales_transaction_fa select d1.calendar_year, d2.store_name, sum(f.sales_quantity) from pos_retail_sales_transaction_facts f join date_dimension d1 on f.date_id = d1.id join store_dimension d2 on f.store_id = d2.id group by d1.calendar_year, d2.store_name; # This will sum sales quantity and group by calendar year and store region -select d1.calendar_year, d2.store_region, sum(f.sales_quantity) as sales_quantity from pos_retail_sales_transaction_facts f join date_dimension d1 on f.date_id = d1.id join store_dimension d2 on f.store_id = d2.id group by d1.calendar_year, d2.store_region; \ No newline at end of file +select d1.calendar_year, d2.store_region, sum(f.sales_quantity) as sales_quantity from pos_retail_sales_transaction_facts f join date_dimension d1 on f.date_id = d1.id join store_dimension d2 on f.store_id = d2.id group by d1.calendar_year, d2.store_region; + +select * from pos_retail_sales_transaction_facts f join date_dimension d1 on f.date_id = d1.id join store_dimension d2 on f.store_id = d2.id; \ No newline at end of file doc/expected_queries.txt 960477d43d4068cc79a5e38ad7cd92490ef2d55a aeden aeden@78b0de1e-7a20-0410-a083-82450d3afd0a http://github.com/bcotton/activewarehouse-demo/commit/681951dd08014e7f0d4a6335b0e2c5651c9e279d 681951dd08014e7f0d4a6335b0e2c5651c9e279d 2006-11-06T17:07:20-08:00 2006-11-06T17:07:20-08:00 Fixes to demo.
