Short answer: Don't name your fields (in scoped apps) 'event'. It will come back to haunt you in notifications.

 

Background:

I was making a demo app. I extended task to a scoped table called x_meetup_event. From there I created a m2m table with sys_user (x_meetup_m2m_invite). This table basically has two fields user (reference to sys_user) and event (reference to x_meetup_event.)

 

As records are added the table, my plan was to trigger a scriptless notification with details about the event by dot walking through the event field, for example:

 

Event name: ${event.short_description}

Start time: ${event.work_start}

 

It took me a while to figure out why I wasn't getting any text next to the labels. After quite a bit of testing in the global scope and with other table names, it comes down to 'event' is a reserved word in notifications. Sure, now that I know, it all sounds so simple. The documentation mentions event.parm1 and event.parm2 are available in mail scripts, but the Notifications page says nothing about ${event}. This is one case where I appreciate the u_ prefix on tables and fields in the global scope.

 

You may run in to similar issues with fields named 'email', 'template', 'email_action', and 'current'. In general, stay away from naming fields the same as objects. If I were still in charge of the Technical Best Practices docs, I'd add this in there. Right martin.wood and enojardi?

Description

 

Mimeo copies hierarchical data between tables while preserving sys_ids on reference fields all without scripting! This is great for moving data from a global app to a scoped app, or updating data on a secondary table for reporting or limited access use cases. Using familiar tools such as the auto mapping feature and mapping assist borrowed from import set transform maps, you can quickly constructed a map of tables and fields to copy. Mimeo identifies the reference fields that need new sys_ids and updates them to point to new records in the target tables.

 

Mimeo also allows you to quickly debug and retest your maps. These maps can be captured in update sets to easily migrate them to other instances for additional testing and production.

 

Common use cases

  • Migrate data from a global app's table structure to a scoped app's tables
  • Replicate (all or part of) data from one set of tables to another for reporting or users with separate ACL structure

Compatibility

  • January 3, 2017: Tested with Geneva, Helsinki (P7), and Istanbul (P0)

 

Explanation/Demonstration Video

Description

Enable your no-code and low-code developers to create solutions to commonly scheduled tasks. With no scripting, you can select and update a set of records on a table, trigger notifications, and more. If the scriptless solution doesn't completely answer your questions, check "Advanced" and get a head start on your JavaScript code to unleash the power of your low-code and pro-code developers.

 

How this never made it in to the platform before today, I don't know. I was tinkering around with another project and asked myself "How do scriptless business rules work?" With a little reverse engineering and a few emails to my friends in development I was able to marry that with the condition field to come up with this solution.

 

Common use cases

  • Send approval reminders if not approved in 7 days
  • Cancel approvals after 30 days
  • Send Knowledge base article reminders 30 days before expiration

Compatibility

  • October 20, 2016: Tested with Helsinki P4 and Istanbul (pre-release)

 

Explanation/Demonstration Video

In this video I show you how to use the list filter condition builder to create complex queries and use them in your scripts.

 

No need to know SQL programming.

No need to try and decipher GlideRecord addQuery/addOrCondition nuances.

Just build your filter, copy the query, and swap out the hard coded values for variables!

45Kingston Part 2December 14, 2017

In part 2 of our series on Kingston Platform features, Chuck and Pradeep dive in to many of the other platform features that were released in Kingston. Find out what's new and how it can be applied to your applications and integrations to make development, testing, and deployment faster than ever.

Quick tip: Avoiding scripting issues when your field is named "query" or "next".

Sometime between 2008 and 2010, when I was a customer, ServiceNow introduced the tabbed interface for forms. It wasn’t until 2015 that this became the default. For years I had to tell people, “There’s a better way to look at these forms…” then show them what to click to get there (painful). Once they went to tabbed forms, few ever went back. I yearned for a way to make the system default to tabbed forms, then I where this gem was hiding - user preferences.

 

You can make tabbed forms, list sort order, theme, or any other user preference a default for new users quite easily. While you cannot prevent them from changing it to something else afterward, you can certainly put them on a path to a better (or at least consistent) experience.

 

Let’s say you want all new users to have their UI16 left navigator default to Favorites instead of the standard menus/modules. Here's how:

 

1. Click the star icon to change your view to favorites

2. Navigate to sys_user_preference.list (or filter on pref to filter down to User Administration> User Preferences.) DO NOT, go back to the menus/modules directly or you’ll change the value of the user preference we’re trying to set.

3. Sort the list by recently updated records.

4. Locate your recently change preference for favorites (navigator.activeView). You may have to filter on records where you are the user.

 

5. Open the record.

6. Check the System box

7. Remove the User value.

 

8. Insert (not Update, not Save) the record.

 

Login or impersonate a user who has never tried UI16 before… You’ll see it default to favorites. While this isn’t terribly useful for a new user, it serves as an example how you can make default user preferences.

K16 Lab: Source Control

Posted by Chuck Tomasi Employee May 4, 2016

Hello fellow ServiceNow Developers!

 

Chris Maloy and I are excited to be in the first lab session following the opening key note on Tuesday May 17 at 10:00 to introduce you to one of our favorite Helsinki developer features - Source Control.

 

Join us for this hands-on lab as we introduce you to our Git integration, the ways it can help you manage your development across multiple releases, and the best practices to become effective. Chris, me, and a team of us have been working closely with the platform and integrations teams on this feature extensively for the past few months. We know once you start using it, you'll want to use it all the time.

 

Here's our agenda for this lab:

  • Introduction to source control followed by a hands-on lab.
  • Tagging and branching followed by a hands-on lab.
  • Conflict management followed by, yes, another lab.
  • Stashing, and of course, another lab.

 

If you have been to one of my sessions in the past, you know that I encourage participation - OK, perhaps "bribe" is a better word. Note for newbies - sit close to the front.

 

Sign up today and I'll see you in Vegas!
