ruby - Send user email 24 hours after inactivity, rails -


basically, want send email reminder user if haven't made posts within 24 hours of being created. confused on how send email without first making action, such create or update.

controller users_controller.rb

def run   @user = current_user   if time.now.utc == @user.created_at + 24.hours && @user.microposts.empty?     usermailer.twentyfour_email(@user).deliver   end end

mailer user_mailer.rb

def twentyfour_mailer   @user = user   mail(to: @user.email, subject: 'post on site!') end

you don't need happen via controller action, need cron job fire off task (the whenever gem this). might like:

every 1.day, :at => '4:30 am'   runner "user.notify_lazy_users" end

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
