Making controller code dry in rails

Question

I have two controllers having update action. Both the action have similar code and I am in a confusion how to remove duplication and make it dry. Code climate showing duplication problem in this one. Here are the details.

Controller 1:
respond_to do |format|
  if @business_profile.update(business_profiles_params)
    format.html { redirect_to settings_path, notice: t('setting_successful_message') }
  else
    format.html { redirect_to settings_path, alert: t('setting_failure_message')
  end
end

Controller 2:
respond_to do |format|
  if @contact.update(contact_params)
    format.html { redirect_to contacts_path, notice: t('contact_successful_message') }
  else
    format.html { redirect_to contacts_path, alert: t('contact_failure_message')
  end
end

so I want this similar content to be in one.

They are both missing ends to the if block and the first one probably has a typo in stting_failure_message. Both have missing curly right braces (}) in the else block. There may be more subtle issues.

Get the code running and passing controller tests before worrying about optimizations like extracting a shared method to call from the two controller update methods. For what it's worth, the current degree of duplication looks about right to me, in the local clarity of expression and independence in changes versus abstraction to de-duplicate code trade off.
