Ruby on Rails

I want send an SMS each 5 minutes to my users. At the moment, my application sends an SMS during the creation of an account.

 

 

   # users_controller.rb
    def create
          @user = User.new(user_params)
          if @user.save
            @user.send_activation_email
            @user.send_daily_sms
            flash[:info] = "Veuillez contrôler votre boîte mail pour activer votre compte."
            redirect_to root_url
          else
            render 'new'
          end
        end


    # user.rb
    def send_daily_sms
   
        # put your own credentials here
        account_sid = '**********************'
        auth_token = '**********************'
     
        # set up a client to talk to the Twilio REST API
        @client = Twilio::REST::Client.new account_sid, auth_token
     
        @client.account.messages.create({
        :from => '**********',
        :to => '***********',
        :body => 'Salut',  
        })
      end

I already have scheduled mails working in my project by doing this :

   

 # schedule.rb
    every :day, :at => '12pm' do    
      rake "email_sender_daily"
    end
    # My task
    task :email_sender_daily => :environment do |_, args|
      User.find_each do |user|
        UserMailer.daily_mail(user).deliver_now if user.daily == true
      end
    end
    # My UserMailer
    def daily_mail(user)
    @user = user
    mail to: user.email, subject: "Mail journalier"
    end

I'm showing you this because, with the UserMailer, I know how to access it from an other file. Here, I'd like to do the exactly the same for SMS, but how can I access the method that is in my Model ? If not, where can I put this method to be able to access it from my rake task ?
