Foreword: maybe I misunderstand the conception of the service objects and should to design an another implementation. Thank you in advance.

I create the service object for a sms confirmations. User must confirm his actions when:

  • He submits a phone number (updates own profile);
  • He confirms the transaction;
  • He does other important action;

Here is the communication scheme: enter image description here

Code:

profile_controller:

def update

  @profile.assign_attributes(profile_params)
  if @profile.valid?
    confirm = SmsConfirmationService.new({user: current_user,
                                          phone: profile_params["phone"],
                                          kind: :phone})
    confirm.confirm_phone
  else
    ...
  end

end

sms_confirmation_service:

class SmsConfirmationService

  attr_reader :status

  def initialize(params)
    @user = params[:user]
    @phone = params[:phone]
    @kind = params[:kind]
  end

  def create_pin
    pin = Pin.new(code: rand(0000..9999).to_s.rjust(4, "0"),
                  profile_id: @user.profile.id)
    pin.save

    send_sms(pin.code)
  end

  def send_sms(code)
    # call to SMS-provider API and check the status

    render_view
  end

  def render_view
    template = ActionView::Base.new(ActionController::Base.view_paths, {})

    if @kind == :phone
      template.render(file: 'confirmation/confirm_phone')
    end
  end

end

I stuck on the render_view method. I get a 'Missing template profile/update', but according to logs, the template is rendered:

....
Rendered confirmation/confirm_phone.html.haml (6.7ms)
  (0.1ms)  begin transaction

ActionView::MissingTemplate (Missing template profile/update, application/update with {:locale=>[:ru], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :haml, :jbuilder]}.

How to resolve it?
