Region Attributes Feature in APEX 3.1

Patrick Wolf blogged about a new feature of APEX 3.1 called Region Attributes.  I remember trying to get this in to HTML DB 1.6, back when I was the Product Manager in 2003!

Basically, this feature enables you to specify a parameter at the region level which, in turn, will be placed where the #REGION_ATTRIBUTE# tag is located in the template itself.

This feature will definitely cut down on the number of templates required for an application, as going with Patrick's example, the width of a region template can be defined differently for each instantiation of that template.

I just ran into this issue with a client and had to use a slight workaround.  We have an application with 7 tabs - each of which is a different function.  We wanted to indicate which function a user was performing by placing the corresponding icon in the region itself.  I did not want to have to create 7 almost identical region templates, as that would be too cumbersome to manage.

So, I simply created an Application Item called G_ICON, and then referred to that in my region template using the following notation: &G_ICON.

On each page, I created a Before Header computation that sets the value of G_ICON.  Thus, as the user moves from tab to tab, they will see a different icon, and I only have to manage the contents of a single region template.

This method will be unnecessary once APEX 3.1 is released, but if you do have the need for a very dynamic region or other template, it may come in handy today and in the future.

You just didn't offer enough bottles of Maker's Mark as your bribe. ;)

Whose Deck is it Anyways?

This year at KScope, we're going to try something new.  And fun.  And funny to watch - we hope.  It's called "Whose Deck is it Anyways?", and will occur on Sunday at 8:30pm.  It's only 30 minutes, but it will likely be the best 30 minutes of the conference.  Or at least the most embarrassing.

Here's what we're going to do: the will be four 5-minute presentations - one on each of the following: BI, EPM, Database & APEX.

Sound interesting?  Probably not.  We get that, too.  So here's what we did.

Each 5-minute session will be presented by a non-expert.  For example, it's highly likely that I'll be presenting on BI or EPM.

To make it even better, each slide deck will be prepared by the corresponding expert.  So again, it's highly likely that my slide deck's creator will be either Stewart Bryson or Edward Roske.  If nothing else, this session will be a crash course in how not to make cohesive, easy to read slides.

Interested now?  Ya,…

Spaced Out

A while back, I wrote about how to give the Universal Theme a face lift.  If you follow the steps in that post, the base font for an APEX application with the Universal Theme can easily be changed.

While that's all well and good, sometimes you only want to change the font for a report, not the entire page.  One of the applications that I'm building contains a number of IRs based mostly on log data.  Thus, having that data in a monospaced font would make it a whole lot easier to read.

You can search Google Fonts for monospaced fonts by selecting only that option on the right-side menubar.  You can also opt for the standard yet kinda boring Courier and achieve the same thing.

To implement this in your application, follow the steps in my other post, but stop shy of the final step.  Instead of pasting in the text that I specify, paste in the following to the Custom CSS field in Theme Roller, using the name of the font you selected for the font-family:

.a-IRR-table tr td { font-fam…

#fakecode

Unless you've managed to somehow filter out everything about US politics over the last few months (and if you have, please let me know your secret), then you've likely heard about "fake news".  From a high level, my basic understanding of "fake news" is that it refers to stories or websites that are fabricated to advance the political beliefs and/or ideologies of one site or the other.  Your definition may differ.

So what is fake code?  That, I can at least try to explain in a bit more detail.

The other day, I saw this image posted on Kris Rice's twitter feed:



I thought it was a joke, but it's actually a real book. That made me laugh.  Then cry.  Then I read the book, mainly since it's only 4 pages.  Believe it or not,  there's actually some really good content packed in there.  Let me summarize:

If you choose to copy code from Stack Overflow, the OTN forum, or anywhere, really, there's a few things to keep in mind:
