Eager Load Relations of Morphed Models in Laravel 5.8.22

The Laravel team released v5.8.22 yesterday with a new morphWith method to eager load relationships of morphed models. This release is packed with new features so be sure to check out the full release notes and a few notes about some of the new features below.

First, a new @componentFirst directive was added, which is similar to how @includeFirst works:

@componentFirst(['missing/file', 'found/file'])
@slot('title', 'Test Component')

Next, a new withMorph method was added when you want to load relations of morphed models eagerly:

$comments = Comment::query()
->with(['commentable' => function (MorphTo $morphTo) {
$morphTo->morphWith([Post::class => ['user']]);

I would recommend checking out Pull Request #28647 for a better understanding of how this works. One benefit of this approach is that nested relationships are supported by using with (as seen in the above example).

Next, a new containsAll method was added to the Str utility class which determines if a given string contains all array values:

// true
Str::containsAll('taylor otwell', ['taylor', 'otwell']);
// false
Str::containsAll('taylor otwell', ['taylor', 'xxx']);

Next, error handling for maintenance mode commands was introduced which now outputs a failed message and an exit code of 1 if either up or down commands fail.

Next, the TestResponse::assertJsonValidationErrors method now has message value assertions which enables you to check both error keys and messages:

'key' => 'validation message'

The JSON validation errors message still allows index arrays which will assert a matching key, and a mix of both indexed array values and associative arrays of key and message values.

This assertion also accepts an array of messages:

'key' => ['validation message', 'another validation message'],

I also wanted to give a massive shout-out to Tetiana Blindaruk for handling the changelog and releases for Laravel. It’s not an easy job to consolidate all the merged pull requests and commits and format them into a clean changelog. Thank you, Tetiana!
