Make integrations with other services more resilient using a Queue


One downside of automating things is dealing with outages. Sometimes services go down, and are not available for some period of time. When this happens, how does it impact your automation?

If you don't design your automation carefully, you might lose the data entirely. Or get spammed by hundreds of submissions when it comes back up. Handling this correctly does end up needing some understanding of how the automation works, as well as any quirks of the remote system.

Automatically update a spreadsheet of active products


One of our e-commerce clients has several thousand active products. As a distributor, their clients are retailers, some of which like having an up-to-date product spreadsheet.

Using the Events, Conditions, and Actions (ECA) module along with a Views Data Export view of all products, we created a view of all the relevant fields that exports a spreadsheet of all their products, and saves it in their private media system once per day.

Change the display of an event after it happens


Event Calendars seem to be very common on the Drupal sites we build. One of the best ways of improving engagement on a site is to add content about the event after it happens. People who attended an event might come back for a recap, or to see pictures or notes from other participants, while people who did not attend can get a sense of what a future event might be like based on your past events.

Cache-bust pages containing embedded content


The saying goes, there are two hard problems in computer science: caching, naming things, and off-by-1 errors. While Drupal certainly has not solved the naming things, it has made a valiant attempt at a decent caching strategy. And for the most part it works great, allowing millions of lines of code to load up quickly the vast majority of the time.

This is more a tip about our favorite automation tool, the Events, Conditions, and Actions (ECA) module, and how it can get you out of a bind when Drupal caching goes too far.

Use AI to write alt text for your images


Hot off the presses! A brand new module, AI Image Alt Text, uses your configured AI engine to write Alt text for your images, based on AI vision models. When you turn this on, you get a "Generate with AI" button next to image fields, where you can easily get AI to analyze your image and come up with alternative text.

With some quick tests, I'm finding it's describing the image better than I typically do.

Show a mix of future and past events


Another automation we did for Programming Librarian, a site for librarians to plan educational programs, involved events. They wanted to always feature 3 events on the home page, and the most important events were in the future. If their schedule is full, they wanted 2 future and 1 past event visible -- but they don't always have upcoming events, so there might be 0, 1 or 2 future events, and 3, 2, or 1 past events.
