Plugins - TableauEngine

TableauEngine is a AJAX-based photo album engine ported from the original Tableau photo album for rails, found at http://creativi.st/tableau. Changes to the original Tableau include:

integration with LoginEngine and UserEngine
upgrade to Lightbox 2.02

This software package is developed using the Engines plugin. To find out more about how to use engines in general, go to http://rails-engines.rubyforge.org for general documentation about the Engines mechanism.

Installation

Create your Rails application, set up your databases, grab the Engines plugin and the TableauEngine, and install them.
Install the TableauEngine into your vendor/plugins directory
Modify your Engines.start call in config/environment.rb
```
 Engines.start :tableau # or :tableau_engine
```

Edit your application.rb file so it looks something like the following (optional):

 class ApplicationController < ActionController::Base
   include TableauEngine
 end

Edit your application_helper.rb file (optional):

 module ApplicationHelper
   include TableauEngine
 end

Perform any configuration you might need. You’ll probably want to set these values in environment.rb (before the call to Engines.start):
```
 module TableauEngine
   config :some_option, "some_value"
 end
```

Initialize the database tables. You can either use the engine migrations by calling:

 rake engine_migrate

  to move all engines to their latest versions, or

    rake engine_migrate ENGINE=tableau

  to migrate only this engine.

The TableauEngine provides a default stylesheet and a small javascript helper file, so you’ll probably want to include the former and almost certainly the latter in your application’s layout. Add the following lines:
```
   <%= engine_stylesheet "tableau_engine" %>
   <%= engine_javascript "tableau_engine" %>
```
