Rails how to improve if record exists?

Player.joins(:results).where("results.win = true AND results.competition_id = 4").order("results.count DESC")

photo = person.photos.where(kind: "face").first
photo.destroy if photo

# procede with creating new photo object

record = GoldenResult.find_or_create_by( platform_id: platform_id, 
         release_id: release_id, configuration_id: configuration_id ) do |record|
  # fill in additional data for a new record if needed
end

def create
  if EmployeeTitle.exists?(name: employee_params[:title_attributes][:name])
    # find title and use it?
  else
    @employee = current_user.employee.build(employee_params)
  end
  if @employee.save
    flash[:success] = "Employee #{@employee.title.name} created."
    redirect_to @employee
  else
    render 'new'
  end
end

def create
  @employee = current_user.employee.build(employee_params)
  if @employee.save
    flash[:success] = "Employee #{@employee.title.name} created."
    redirect_to @employee
  else
    render 'new'
  end
end

def title_attributes=(attributes)
  self.title = EmployeeTitle.find_or_create_by_name(attributes[:name])
end

EmployeeTitle.find_or_create_by(name: attributes[:name])
