In Drupal, there's a drush entity:save (alias esav) command which is useful when you want to save entities in bulk.

I needed to use this command the other day to save some entities that update a field value on the entity during a presave hook. Instead of running a database update to change the data, I just triggered the update by saving the entities, e.g

drush esav your_entity_type_id 12167,12168,12169,12170,12171,12172

To save all entities of a type, you can use:

You can check the request to detect whether you're in a Drupal modal:

$request->query->get('_wrapper_format') === 'drupal_modal';

I needed to use this when embedding a block plugin within a modal form, and wanted to display the block slightly differently than it normally gets displayed.

Instead of using the ternary operator to set a value or a default if that value doesn't exist, Twig's "default" filter provides a more compact and readable way of doing so. For example:

{% set alignment = alignment ? 'pagination--' ~ alignment : 'pagination--center' %}

Becomes:

{% set alignment = 'pagination--' ~ alignment|default('center') %}

This method is from a custom entity class. The revision_id needs to match your entity's revision entity key.

On a Drupal 8, Bootstrap based site that I’m currently working on we have a couple of forms that have a boolean ‘Acknowledgement’ field that is displayed at the bottom.

Because we’ve enabled “Smart form descriptions (via Tooltips)” in the theme settings, the form field descriptions are not visible, but in this case we wanted to display it below the field, instead of as a tooltip.

This snippet adds the entity type id to the html body tag classes when on the canonical entity page.

I've been working on a Drupal 8 Bootstrap 3 site and was wanting to use the spacing utilities that come with Bootstrap 4.

These utilities provide a range of shorthand responsive padding and margin classes:

I'm excited to be discussing migration in Drupal 8 at the next Drupal Cape Town meetup, Wednesday the 27th of February 2019. The broad outline of my talk is:

The New York Times has a tool on their site which allows you to check how much warmer a city was in 2018, compared to an average calculated using data from 1981 to 2010. The data, provided by AccuWeather, comes from a database of more than 3800 cities worldwide which shows that about 83% of cities experienced average temperatures higher than normal last year.
