Laravel 10.4 Released

The Laravel team released 10.4 with a File::json() method, converting existing HasMany relationships to a HasOne relationship, a new test response assertion, and more.

File::json() method

Austin White contributed a File::json() method as a convenience for getting JSON encoded data from a file:

// Before
$contents = File::get('sample.json');
$data = json_decode($contents, true);

// After
$data = File::json('sample.json');

Assert unsupported media type

Shamimul Alam contributed an assertion helper for the 415 Unsupported Media Type response status code:

$response->assertUnsupportedMediaType();

Convert an existing HasMany to HasOne relationship

Luke Kuzmish contributed converting a HasMany to a HasOne and a MorphMany to MorphOne

Take this example of having to define two relationships:

class User extends Model
{
    public function logins(): HasMany {
        return $this->hasMany(Login::class, 'some_id', 'the_other_id');
    }
    public function latestLogin(): HasOne {
        return $this->hasOne(Login::class, 'some_id', 'the_other_id')->latestOfMany();
    }
}

With this PR now, you can do the following instead with the ->one() method:

class User extends Model
{
    public function logins(): HasMany {
        return $this->hasMany(Login::class, 'some_id', 'the_other_id');
    }
    public function latestLogin(): HasOne {
        return $this->logins()->one()->latestOfMany();
    }
}

The one() method is available on the HasMany, HasManyThrough, and MorphMany.

Create macroable method for paginationInformation

Frans Slabbekoorn contributed the ability to define a macro for paginationInformation that allows customizing pagination information without having to extend all resources as a base resource:

/** @mixin \Illuminate\Http\Resources\Json\ResourceCollection */
class ResourceCollectionMixin
{
    public function paginationInformation(): Closure
    {
        return fn ($request, $paginated, $default) => collect($default)->mapWithKeysRecursively(fn ($item, $key) => [Str::camel($key) => $item])->toArray();
    }
}
