Commands

Commands represent a request to change the application state.

They are created from the Rails controller and sent to the domain server. The Domain server validates them and creates an events, if they are valid.

In Ruby a command is located in app/commands as a class that includes the ActiveEvent::Command module.

You can use the attributes method to declare the functions and serializations.

attributes :id, :attr1, :attr2, :attr3, ...

To enable the use of form helpers from Rails, you can include ActiveModel::Model before the ActiveEvent::Command. To automatically generate form_for urls and names, you will have to override persisted? and self.model_name methods. Take a look at the scaffolding.

A complete example:

class RegisterUserCommand
  include ActiveModel::Model
  include ActiveEvent::Command

  attributes :id, :email, :salt, :encrypted_password
  attr_accessor :password, :password_confirmation

  # add your hooks to encrypt the password
end
