Laravel Helpers

Collection of helpers for re-use accross a few of our projects

Laravel Helpers

Installation

Install via composer

composer require custom-d/laravel-helpers

Upgrade V2 to V3

ViewAny plicy now checks for a viewAny permission and not list for the viewAny permission check
Dropped support for php 7.3 & 7.2
Dropped support for Laravel 6 & 7
marked execute helper as deprecated
fixed Model::orWhereNotNullOrEmpty method to do correct query

Crud Policy Trait

by using the CustomD\LaravelHelpers\Models\Policies\CrudPermissions trait in your model policy along side Spatie role permissions using wildcard permissions you can have your policy look like:

namespace App\Models\Policies;

use App\Models\Policies\Traits\CrudPermissions;
use Illuminate\Auth\Access\HandlesAuthorization;

class UserPolicy
{
    use HandlesAuthorization;
    use CrudPermissions;
}

and it will check for the following permissions:

user.viewAny (list is v2 and earlier)
user.view
user.create
user.update
user.delete
user.restore

for user locked based policy permissions you can add the following method to your model: userHasPermission(User $user): bool

Helpers

execute - this helper runs an execute action on an action file with dependancy injection on the contructor

execute(Action::class, $param, $param2);
execute(Action::class);

//resolves as
$app->make(Action::class)->execute(...)

If you discover any security related issues, please email instead of using the issue tracker.

DB Macros

Null Or Empty

when dealing with some of our legacy databases we have some columns where the entry is either null or empty and these macros allow you to query this without the double entries:

Model::whereNullOrEmpty('column_name'); //generates select * where 1=1 and (column_name is null or column_name = '')
Model::orWhereNullOrEmpty('column_name'); //generates select * where 1=1 or (column_name is null or column_name = '')
Model::whereNotNullOrEmpty('column_name'); //generates select * where 1=1 and (column_name is not null and column_name != '')
Model::orWhereNotNullOrEmpty('column_name'); //generates select * where 1=1 or (column_name is not null and column_name != '')
Model::whereNullOrValue('column_name', [$operator],$value, [$boolean]); to check if column null or specific value (follows laravel where specification where operator is optional)

Case insensitive statments

Model::iWhere('col',$value);
Model::iWhere('col',$operator,$value);
Model::iWhere(['col' => $value]);

Enforced Non Nullable Relations (orFail chain)

function related(){
  return $this->hasOne()->orFail();
}

DB Repositories

use of repositories via extending the CustomD\LaravelHelpers\Repository\BaseRepository abstract example in the UserRepository.stub.php file

Observerable trait (Deprecated)

adding this trait to your models will automatically look for an observer in the app/Observers folder with the convension {model}Observer as the classname,

you can additionally/optionally add

protected static $observers = [ ...arrayOfObservers]

to add a additional ones if

Replace this with

use Illuminate\Database\Eloquent\Attributes\ObservedBy;
use App\Observers\UserObserver;

#[ObservedBy(UserObserver::class)]
#[ObservedBy(AnotherUserObserver::class)]
class User extends Model
{
    //
}

Record or Fake HTTP Calls

The RecordsOrFakesHttpCalls trait will allow you to record or fake http calls in your tests. This is useful for testing external api calls without actually calling them.

Add the trait to your PHPUnit test file, ensure the tests/stubs/ directory exists, and then wrap your test code in a callable:

  public function test_external_api()
  {
      // $this->record = true; // Toggle to create recorded files
      $this->processRecordedTest(
          'test_external_api',
          function () {
              // Any HTTP calls made by MyServiceClass will be recorded or returned from recorded responses, depending on `$this->record` above.
              $result = resolve(MyServiceClass::class)->execute('foo');
              $this->assertEquals('bar', $result->value);
          },
          'json'
      );
  }

Date Manipulation

You can set user timezones via the following options:

optionally create a migration with:

Schema::table('users', function (Blueprint $table) {
            $table->string('timezone', 40)->nullable();
        });

in user model:

pubic function timezone(): Attribute
{
  return Attribute::get(fn($value) => $value ?? config('app.user_timezone'));
}

Additionally you can set defaults on the timezone via the attributes method or a setter or even in the migration.

in your app config file add the user_timezone parameter.
add the UserTimeZone middleware to your api middleware list.

You can now access the current requests timezone via config('request.user.timezone')

Date(Carbon) Helpers attached to above:

methods available:

setUserTimezone(string $timezone) : Static - sets the users timezone (default set by helper)
getUserTimezone() : string - gets current users timezone
setSystemTimezone(string $timezone) : Static - sets system timezone (Default app.timezone)
getSystemTimezone(): string - gets teh current timezone
toUsersTimezone(): Static - returns carbon instance set to users timezone
toSystemTimezone(): Static - returns carbon instance set to system timezone
usersStartOfDay(): Static - returns carbon instance set to start of users day (converts to users timezone => start of day => to systemtime)
usersEndOfDay(): Static - users end of day
usersStartOfWeek(): Static
usersEndOfWeek(): Static
usersStartOfMonth(): Static
usersEndOfMonth(): Static
usersStartOfQuarter(): Static
usersEndOfQuarter(): Static
usersStartOfYear(): Static
usersEndOfYear(): Static
parseWithTz(string $time): Static - parses the time passed using the users timezone unless the timezone is in the timestamp
hasISOFormat(string $date): bool - checks if the date is in iso format.

You can also use the CDCarbonDate to create a few different date objects.

Value Objects

Example:

<?php
declare(strict_types=1);

namespace CustomD\LaravelHelpers\Tests\ValueObjects;

use CustomD\LaravelHelpers\ValueObjects\ValueObject;

final readonly class SimpleValue extends ValueObject
{
    protected function __construct(
        public string $value,
        public int $count = 0
    ) {
    }

  /** optionally add some validation rules, leave out the method if the type sets are enough **/
    public function rules(): array
    {
        return [
          'value' => ['string', 'max:250'],
          'count' => ['max:99'],
        ];
    }
}

$simpleValue = SimpleValue::make(value: 'hello World', count: 33);

Or using attributes to make advanced objects.

<?php
declare(strict_types=1);

namespace CustomD\LaravelHelpers\Tests\ValueObjects;

use Illuminate\Support\Collection;
use CustomD\LaravelHelpers\ValueObjects\ValueObject;
use CustomD\LaravelHelpers\ValueObjects\Attributes\MakeableObject;
use CustomD\LaravelHelpers\ValueObjects\Attributes\ChildValueObject;
use CustomD\LaravelHelpers\ValueObjects\Attributes\CollectableValue;
use CustomD\LaravelHelpers\ValueObjects\Attributes\MapToCase;

#[MapToCase('camel')]
final readonly class ComplexValue extends ValueObject
{
    public function __construct(
        #[ChildValueObject(StringValue::class)]
        readonly public StringValue $value,
        readonly public array $address,
        #[ChildValueObject(SimpleValue::class)]
        readonly public SimpleValue $simpleValue,
        #[MakeableObject(Constructable::class)]
        readonly public ?Constructable $constructable = null,
        #[CollectableValue(SimpleValue::class)]
        readonly ?Collection $simpleValues = null,
    ) {
    }

}

Best practice is to use the make option, which will validate, if you use a public constructor it will not.

These should all be marked as READONLY and FINAL.

The attributes available are:

ChildValueObject(valueobectclass) - which will make a new valueObject
CollectableValue(valueobjectclass) - which will convert an array to a coollection of the value objects
MakeableObject(class, [?$spread = false]) - will look for a make method or else construct if passed an non object - if spread is true will expand the array else will pass the array as a single argument
MapToCase(('snake|camel|studly')) - for the fromRequest method

Mapping Valueobject from your Request would be as easy as doing one of the following:

//eiterh in your code where you need it.
$object = ValueObject::fromRequest($MyFormRequest, true|false); //defaults to true (validated only values, false will be all from the request);

//or add a method to your FormRequest
public function getObject(): ValueObject
{
  return ValueObject::fromRequest($this);
}

Larastan Stubs

these are temporary only till implemented by larastan

add to your phpstan.neon.dist file

parameters:
    stubFiles:
        - ./vendor/custom-d/laravel-helpers/larastan/blank_filled.stub

Filament Plugin

** this is only if you want to deal with user timezones for display, else will be in UTC in the Filament panel **

simply add to your panelProvider ->plugin(UserTimeZonePlugin::make())
