Eager Lazy Collections Added to Laravel 6.1 image

The Laravel team announced the immediate availability of Laravel v6.1.0 with a new eager() method added to Lazy Collections along with the latest updates for Laravel 6.

LazyCollections—a new feature added to Laravel 6—now has an eager() method which “enumerates all of the lazy collection’s values, and constructs a new LazyCollection instance, which will now be backed by an array.”

An example from pull request #29832 illustrates its use:

$users = User::cursor();
 
$users = $users->eager();
 
$count = $users->count();
 
$users->each(function ($user) {
//
});

Without eager() the above would fetch results twice.

Next, the purge() and getChannels() methods were added to the LogManager class in order to purge resolved log driver/channel. The test in pull request #30132 illustrates its use:

public function testLogMnagerPurgeResolvedChannels()
{
$manager = new LogManager($this->app);
$this->assertEmpty($manager->getChannels());
 
$manager->channel('single')->getLogger();
$this->assertCount(1, $manager->getChannels());
 
$manager->purge('single');
$this->assertEmpty($manager->getChannels());
}

Next, a new assertNoContent() method was added to the TestResponse class:

// Before
$response = $this->get('api/endpoint');
 
$response->assertStatus(409);
$this->assertEmpty($response->content());
 
// After
$response = $this->get('api/endpoint');
 
$response->assertNoContent(409);

Next, a new withCookies method was added to TestResponse, making it easier to send cookies in HTTP tests:

// Before
$cookies = [
'name1' => encrypt('value1'),
'name2' => encrypt('value2')
];
$response = $this->call('get', 'test', [], $cookies);
 
// After
$response = $this->withCookies([
'name1' => 'value1',
'name2' => 'value2'
])->get('test');
