Interaction

Interactions are meant to keep controllers and models or any other business logic slim (YAY). Keep intention of class clear when using interactions, for example: To create a user, a class should be name Users::Create.

If you are using this in a Rails application you might want to use

gem 'simple_interaction-rails, github: "boza/simple_interaction-rails"'

this comes with a generator so you don't have to create individual files :)

Add this line to your application's Gemfile:

gem 'simple_interaction'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simple_interaction

class Klass
  include SimpleInteraction

  fail_with 'ErrorClass'
  requires :param1, :param2     

  private
  
  def run
    method
  rescue => e
    @error = e.message
  end

  def method
    param1 / param2
  end

end

interaction = Klass.run(param1: 2, param2: 1)
interaction.success? #=> true
interaction.error #=> nil
interaction.result #=> 2

Klass.run!(param1: 1, param2: 0) #=> raises Klass::ErrorClass
Klass.run!(param1: 1, param2: 2) #=> 2
