MDWA is a model-driven approach, built by Marcelo Theodoro, to ease the process of develop web applications. MDD gem includes a set of code generation tools to automate repetitive task during Rails development, such as:

• Sandbox environment: Provides a clean environment with user authentication, namespace separation and more;
• CSS templating: YUI3 grid system and beautiful styling
• Multiple layouts
• Smart scaffold generator

MDD is based on top of Rails 3.1, including asset pipeline feature. Add it to your Gemfile with:

gem 'mdd'

Run the bundle command to install it.

After you install MDD and add it to your Gemfile, you need to run the generator:

rails generate mdwa:sandbox

This generator will setup the clean sandbox environment with:

• Multiple layouts;
• Assets ready to be customized;
• User based authentication with Devise (https://github.com/plataformatec/devise);
• Login;
• Public pages - for simple website development.

Check the result:

• Public pages: http://localhost:3000
• Private area: http://localhost:3000/a

The private area requires user authentication. The generator will create a default user:

User: admin@admin.com
Password: admin123
