“Tell me and I forget. Teach me and I remember. Involve me and I learn.”
— Benjamin Franklin
Now that I have gone and thrown the idea out there for all to see, it’s time to get to work and see if I can actually pull this off. To begin, I need to set up the Scoped Application, which is basically a repeat of what I went through to set up the Scoped Application for my little Webhooks project, so there is no need to repeat all of that here. Here is how it came out:
With that out of the way, the next order of business is to create that first table in which to store all of the instances. Again, that is pretty standard stuff and not really worthy of a step by step walk-through of the process, but here is the associated form, which will give you an idea of the columns that I have selected at this point in the process:
Now we have a place to store the information on the participating instances, so it’s time to build the initial set-up process that will populate this table. Before we dive into that, though, I should mention that when I set up the application, I also set up a few System Properties using the UI Action that I created for that purpose a couple of years ago.
That’s been a handy little tool that does a number of things under the hood, but we don’t need to get into all of that here. If you are interested in that for any reason, you can grab an Update Set from here. For this phase of the project, I came up with three properties that I think will be needed in order to do what I would like to do. That may change over time as I get more into the weeds, but for now, here is the list:
That should give us all of the artifacts that we should need to start working on the initial set-up process. As you might have noticed in the above screen shot, I have already created a menu item to launch the initial set-up process from the navigation side bar. Right now, you can also see some of the other menu options for the app, but sometime before things are ready for prime time, my plan is to make all other menu items inactive, and then once the set-up process has been completed, a final step in the process would activate all of the others and inactivate the set-up menu item. For now, though, you can see everything, and it will probably be that way for some time until we get much closer to the end of things.
As for the set-up process itself, there are a number of different ways to go here. I could build something the main UI, where the primary technology is Apache Jelly. I could also build a Service Portal widget, where the primary technology is AngularJS. Both of those are considered Old School at this point, though, and all of the cool kids are now using the Now® Experience UI Framework and the ui-component extension for application development. While that seems like the appropriate way to go, my personal skill set does not yet include mastery of that particular technology, and I don’t really feel like this project would be a good place to address that particular shortcoming in my technical expertise. Since the initial set-up is just one small part of this effort, I am going to take the easy way out and just build a simple widget.
Building a brand new widget starting with a blank canvas is a little bit of a project, though, so that seems like something worthy of its own dedicated installment. Rather than start on that here, let’s take that up next time out.
