Method to render how many days remain in membership - Ruby on Rails -

currently have method called expiration_date calls created_at , adds 1 year date. make method says how many days left until expiration_date , call on view. i'll show model code clarity , make more sense.

model

class subscriber < activerecord::base   validates :first_name, presence: true   validates :last_name, presence: true   validates :email, presence: true   validates :phone_number, presence: true    def date_joined    created_at.strftime("%-m/%-d/%-y")   end    def expiration_date    (created_at + 1.year).strftime("%-m/%-d/%-y")   end    def days_till_expired     #code   end end 

controller

class subscriberscontroller < applicationcontroller   def index     @subscriber = subscriber.all   end    def new     @subscriber = subscriber.new   end    def create     @subscriber = subscriber.create(subscriber_params)     if @subscriber.save       flash[:notice] = "subscriber has been created"       redirect_to new_subscriber_path(:subscriber)     else       render "new"     end   end    def search     @subscriber = subscriber.new   end    def visit     @subscriber = subscriber.find_by_phone_number(params[:phone_number])     if @subscriber       @subscriber.visit =+ 1       @subscriber.save       redirect_to subscribers_search_path(:subscriber)     else       render "search"     end   end end 

i have view form user type in phone_number , flash notice aware them how time have left. think need grab user params of phone number when it's sent in. make sense?

how this

def days_till_expiration   ((created_at + 1.year) - datetime.now).to_i / 1.day end
