### Without Dependency Injection approach using

# app/controllers/aura_controller.rb
class AuraController < ApplicationController
  def show
    Aura.where(user_id: user_id)
  end
end

### With Dependency Injection approach using

# app/controllers/aura_controller.rb
class AuraController < ApplicationController
  def show
    AuraService.get_aura(user_id)
  end
end

# app/services/aura_service.rb
class AuraService < BaseService
  def get_aura
    Aura.where(user_id: user_id)
  end
end

## Which helps us with the future refactoring

# app/controllers/aura_controller.rb
class AuraController < ApplicationController
  def show
    AuraService.get_aura(user_id)
  end
end

# app/services/aura_service.rb
class AuraService < BaseService
  def get_aura
    call_aura_remote_service(user_id)
  end
end
