Devise expire notification on email confirmation

Question

I have included confirmation module in devise gem and it working fine but i need to alert the user with some flash message on after 2 days(based on the devise config) for unconfirmed emails on login.

config.allow_unconfirmed_access_for = 2.days

how to add a button to resend mail for confirmation.

Answer 1

You need to create a button which links to a controller action, and create a route for it like resend_email_path(user) . Inside the controller action you need to include:

  def resend_email
    user = User.find(params[:id])
    user.send_confirmation_instructions
  end

For more information on this method see:

Once you get it working normally you could do it ajaxy with remote: true

To add the flash message , put this in in the controller action where your uncomfirmed user is:

if current_user.confirmation_period_expired?
  flash[:error] = "Confirmation Time Expired. #{link_to 'Resend email', resend_email_path(user)}".html_safe
end
