For a recent project, we were tasked to consume the client's internal data from a custom API. Now, this scenario was lucky for us, the API provides a total item count of about 5000, but when queried with a start date, it provides all revisions of items between then and now. The premise was that the data was to be downloaded at regular intervals, so that content editors didn't need to copy and past to keep product information up to date.
Sometimes during development, a chicken and egg situation happens when business logic intersects with Drupal's mechanisms. For instance, a custom module,
client_business_logic, is built to handle some unique, abstract bit of logic which depends on a taxonomy vocabulary that has fields added to it.
We're just past the second anniversary of 8.0.0. To see how D8 is doing compared to prior releases, we put together the chart above, based on Drupal's usage stats page.
For versions 5.x, 6.x, and 7.x, each new release brought dramatically accelerated growth.
Comparatively, D8 has dropped off a cliff. Adoption is far below that of D7, and even behind D6.
Data protection is one of the primary advantages of Drupal, but sometimes there are exceptions to the rule and you might need to modify a field to account for some change in business needs. There are a few rule bends (read hacks) that can be done to circumvent Drupal's checks and still maintain data integrity. You should only perform this when extending a field or changing something reasonable that is allowed by the database server. For example, expanding a varchar length or changing unformatted string into a formatted text field.
Rather than provide a basic how-to tutorial on Drupal's form API #AJAX functionality, I decided to address a few pitfalls that often frustrate developers, both junior and senior alike. To me, it seems that most of the problems arise from the approach rather than the direct implementation of the individual elements.
As I've said before in my custom views filter handlers tutorial, views is amazing. Today I was writing a custom style plugin. I got the plugin to show up in the list of available formats, but whenever I saved the form, it wouldn't stick.
Note: this code has been tested in Drupal 8.0 and 8.1
At the time of this writing, the Search API module is still in alpha phase. A note from the module maintainers warn that it is unstable. This blog post serves as a way to learn how to write a simple Drupal 8 module to modify Drupal 8's core search without using the Search API module.
I recently spent some time fighting against the Drupal Media and File Entity modules in order to upgrade them from version 7.x-1.x to 7.x-2.x. (To be specific, Media was upgraded from 7.x-1.4 to 7.x-2.0-beta1, and File Entity to 7.x-2.0-beta2). Through this post, I will share with you my trials and tribulations, with the hope that one day no one else will endure the pain and suffering that I have endured.
Google Analytics Module Settings
Drupal's Google Analytics Module is great. There are a few settings though that I recently found out you'll want to pay closer attention to. First is the "Pages" section of the configuration form, which allows you to only include/exclude Google Analytics tracking code on certain pages. The default settings are to exclude the code on the following pages.
