8: Programatically Filter Current Nid from Views Block Listing

Views has a setting to exclude the current nid from the URL from the listing one is currently viewing. This is essential when you have, say, a list of related nodes that are are defined by a category that includes the current node. If you don't exclude the current node, your current node will be listed in the "related content" block on itself. Well, obviously one is related to oneself, one thinks.

First, I tired to accomplish this through the UI with these steps, below.

Twig/Theme Debug Not Working Even Though Set

So, your debug output isn't working.

You checked to make sure you followed all the steps here.

But still... no theme debug output. WTF?

Try turning on and off twig caching. For me, it seemed something was stuck or whatever. First turn it on:

Drupal 8: How to Get Image Style Tokens for Metatags

It turns out that image style tokens are an easter egg of the regular Token module, ported in from the Imagecache Token module on this ticket.

Image style tokens don't show up in the media browser, and so you sort of have to guess at how to use them. I figured it out by studying the merged commit that added the functionality.

SQL Search and Replace in Drupal 8 Body Field

You never know when you're going to encounter data ravaged by clients, cast aside and mauled, an antelope passed by lions to jackals.

But fortunately, data is much easier to repair than a gaping wound.

Here's the SQL query I'd use to replace non-breaking spaces with regular spaces. You'll need to replace it with whatever your search term is:

Drupal 8.4x: Add Timezone to Date or DateRange Field

Here's the controlling issue for adding timezone support to Drupal core. As of now, August 1st, 2017, it doesn't appear to be ready.

Instead, I just added a timezone field to the node using the Timezone module, then appended it to the date range on field preprocess.

This won't work for you if you have multiple dates on an entity with different timezones (you might want to try the patch linked above), but it will fit most use cases.

Drupal 8: Get URI, Title, and Alt from Media Entity Reference Item

Over the last several days, I've railed in my head against the matroshka structure of Drupal entities. But when I tried to break out some helper functions, and when I realized what each of the different properties each entity had, I realized the complexities of entities were warranted. Life is complex, and thus Drupal is complex.

Entity references load a Media Entity, which load an Image from an image field, which load a File. The alt and title are on the Image, while the file URI is on the file.

Get Drupal 8 Media Entity Object from ID

This is pretty simple, but it took me a minute, because I kept trying to use the base Entity class, like an angry baby trying to remove a clenched fist from a bottle.
