Day 28 – Updating User’s List When User Joins App

I’m building an app where I want users to be able to “join” the app. The plan is to eventually have this Kynetx app be a Kynetx powered Twilio app that users can sign up to get reminders based on their current status for the month. This example doesn’t cover users “leaving” the app.

ruleset a60x517 {
  meta {
    name "user-join-quit-data-hash"
    description <<
    author "Mike Grace"
    logging on

  rule running {
    select when pageview ".*"
    pre {
      joinStuff =<<
        Phone: <input id="phone" /><br/>
        Name: <input id="name" /><br/>
        <button id="join">Join</button>
      append("body", joinStuff);
      emit <|
        // get app object for raising web event
        app = KOBJ.get_application("a60x517");

        // get user info when they click join
        $K("#join").live("click", function() {
          var phone = $K("#phone").val();
          var userName = $K("#name").val();

          // raise web event to submit join info
          app.raise_event("user_wants_to_join", {"phone":phone, "userName":userName});

  rule user_wants_to_join {
    select when web user_wants_to_join
    pre {

      // get data passed from web event
      phone = event:param("phone");
      userName = event:param("userName");

      // get time stuff for data hash
      month = time:strftime(time:now({"tz":"America/Denver"}), "%B");
      year = time:strftime(time:now({"tz":"America/Denver"}), "%Y");

      // get data hash to merge in new data
      dataHash = app:dataHash || {};

      // build user's hash that wants to join
      userData = {
        "#{phone}": {
          "name": "#{userName}",
          "yearMonth": {
            "#{year}#{month}": {
              "scheduled": false,
              "completed": false,
              "scheduledDay": false

      // morge user's hash with all other user's hash
      newDataHash = dataHash.put(userData);

    } // end of pre
      notify("added to app","content") with sticky = true;
      emit <|
    fired {
      set app:dataHash newDataHash;

  • 14-18 form for user to submit to “join” app
  • 21 put form on the page
  • 27-32 submit form when user clicks “join”
  • 39 select when the user submits form to “join”
  • 43-44 get user data from submitted form
  • 47-48 get month and year for creating hash data
  • 51 get the saved hash of users who have previously joined the app
  • 54-65 build hash of data for new user that wants to join
  • 68 build new hash of data by merging user who wants to join with data of those previously joined
  • 72 let user know that the form was accepted
  • 74-75 print hash object to console for debug and demonstration
  • 79 save new hash to the app with all the happy user’s data
