Creating links in emails to do things

The other day Chris Perry asked how to create a link in a notification to assign a record to themselves and load up the newly assigned record.

To do this you’d have modify your email to the user, so show the link and then load a page that knew the task and have it redirect. This is what I came up with. A UI page with the following code does it.

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
  <g2:evaluate var="jvar_unwrapped_url" jelly="true">
    var currentUser = gs.getUserID();
    var incidentFromURL = RP.getParameterValue('incident');
    var link = '';
    var incident = new GlideRecord('incident');
    if(incident.get('number', incidentFromURL)) {
      incident.setValue('assigned_to', currentUser);
      gs.addInfoMessage(incident.getDisplayValue() + ' has been updated.');
      link = incident.getLink();
    link || '' + incidentFromURL;
  ${gs.getMessage("Redirecting to your the incident")}...

Client Script

document.location.href = "$[JS:jvar_unwrapped_url]";
