Laravel 5.8.12 released with duplicates collection and other new features

The Laravel team released the 400th release of Laravel (v5.8.12) recently with a new duplicates() collection method and other new features, fixes, and changes to the framework.

First, a new duplicates() method was added to the Illuminate\Support\Collection class:

collect([1,2,1,1,1])->duplicates();
=> Illuminate\Support\Collection {#2938
 all: [
   2 => 1,
   3 => 1,
   4 => 1,
 ],
}

It works by returning the indexes of the duplicate values from the original collection object:

$item[0] = 1 is not a duplicate
$item[1] = 2 is not a duplicate
$item[2] = 1 is a duplicate
$item[3] = 1 is a duplicate
$item[4] = 1 is a duplicate

Similarly, a new duplicates() method was added to the Eloquent collection class, using the $model->is($another) to check for duplicates. Here’s an example from PR #28194:

use App\User;
$one = User::find(1);
$two = User::find(1);
$three = User::find(1);
$users = (new User)->newCollection([$one, $two, $three]);
=> Illuminate\Database\Eloquent\Collection {#2936
     all: [
       1 => App\User {#2929
         id: "1",
         name: "Admin",
         email: "admin@example.com",
         email_verified_at: null,
         created_at: "2019-04-16 23:33:30",
         updated_at: "2019-04-16 23:33:30",
       },
       2 => App\User {#2927
         id: "1",
         name: "Admin",
         email: "admin@example.com",
         email_verified_at: null,
         created_at: "2019-04-16 23:33:30",
         updated_at: "2019-04-16 23:33:30",
       },
     ],
   }

Next, a new getViews() method was added to the FileViewFinder class, which allows you to retrieve all the view information from currently loaded views. Nothing is new here except the ability to access the $views property via the getViews() method.

As of Laravel 5.8.11, the exit code is captured in scheduled command events, which lead to a new PR providing some helpers available to the scheduler:

$schedule->command('my:command')
    ->onSuccess(function () {
        // do something when scheduled command ran successfully
    })
    ->onFailure(function () {
        // do something when scheduled command failed
    })
    ->pingOnSuccess('https://example.com')
    ->pingOnFailure('https://example.com')
    ->emailOnFailure('johndoe@example.com')
;

The emailOnFailure() method is useful when you only want to receive an email for failed scheduled commands as opposed to the emailOutputTo method which is sent no matter what the outcome of the scheduled task. The new scheduler methods have already been added to the scheduling documentation.

Next, the SET datatype was added to the MySQL grammar (learn more about The SET Type):

Schema::create('table_name', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->set("field_name", [ "Possible", "Values" ]);
    $table->timestamps();
});

The last new feature in this release is the addition of the in and not in operators, which can be passed as strings to the query builder:

// these two calls produce the same query
$query->where('foo', 'in', [1, 2]);
$query->whereIn('foo', [1, 2]);

// these two calls produce the same query
$query->where('foo', 'not in', [1, 2]);
$query->whereNotIn('foo', [1, 2]);
