Validations example

This sample app shows how to validate user input on various app layers.

Validations included:

• default HTML5 validations (presence, etc.)
• form object taking care of basic input validations
• command handler taking care of business logic validations (uniqueness) without involving typical Rails model validations, but utilising the concept of interim streams in a way RailsEventStore supports this concept.

Last, but not least: 0 ActiveRecord models given.
