Devise: When resending confirmation email, change flash message - ruby-on-rails

Question

I'm setting up Devise such that users can log in and use the site without having confirmed their email address, similar to this question. But there are a couple of features on the site that users can't use unless they've confirmed.
OK, that's fine. I can check for current_user.confirmed?. If they're not confirmed, I can put a button on the page to have them request the confirmation be sent again.
The issue I'm having is that when they do this while logged in, the flash message they see on the result page is "You are already signed in." Which isn't ideal - I just want to put up the message that the confirmation was sent.
I'm starting down the path of trying to figure out which method of the Devise::ConfirmationController to override, and to what, but I'm hoping someone has done this already.

Answer 1

The reason the flash says "You are already signed in" is because the user is being redirected to new_session_path from the after_resending_confirmation_instructions_path_for method. I would override this method to check if they are logged in. If they are, then don't redirect to new_session_path, set your flash message and redirect to another page.
Override the confirmations controller by putting it in controllers/users/confirmations_controller.rb
class Users::ConfirmationsController < Devise::ConfirmationsController
protected
def after_resending_confirmation_instructions_path_for(resource_name)
if signed_in?
flash[:notice] = "New message here" #this is optional since devise already sets the flash message
root_path
else
new_session_path(resource_name)
end
end
end
Add your confirmationsController to routes->
devise_for :users, :controllers => {:confirmations => 'users/confirmations' }

Answer 2

I think it should look something like this:
module Devise
module ConfirmationsController
extend ActiveSupport::Concern
included do
alias_method_chain :show, :new_flash
end
def show_with_new_flash
# do some stuff
flash[:notice] = "New message goes here"
end
end
end

Answer 3

Could edit
config/locales/devise.en.yml to be more relavent at line:
failure:
already_authenticated: 'You are already signed in.'
or you could do this in your view where flash message has been added
<%=content_tag :div, msg, id: "flash_#{name}" unless msg.blank? or msg == "You are already signed in."%>

Answer 4

I'm using Devise 3.1.0, there's a different method for this scenario instead of after_resending_confirmation_instructions_path_for described in the top voted answer. I modified mine like so:
class Users::ConfirmationsController < Devise::ConfirmationsController
protected
def after_confirmation_path_for(resource_name, resource)
if signed_in?
set_flash_message(:notice, :confirmed)
root_path
elsif Devise.allow_insecure_sign_in_after_confirmation
after_sign_in_path_for(resource)
else
new_session_path(resource_name)
end
end
end
