def create_letters
  Mailshot.transaction do
    recipient_patients.each do |patient|
      letter = MailshotLetterFactory.new(
        patient: patient,
        current_user: created_by,
        letter_attributes: common_letter_attributes
      ).create
      items.create!(letter: letter)

  end
end

#recipient_patients ⇒ Object

The sql view should ideally only have one column - ‘patient_id’ because we use this to filter the patients we want.
