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 alongside Spatie role permissions you can avoid having to write lots of boilerplate methods in your policy file.

Instead of a Policy like this

class UserPolicy
{
    public function viewAny(Authenticatable $user): Response
    {
        return $user->can('users.viewAny');
    }

    public function view(Authenticatable $user, User $targetUser): Response
    {
        return $user->can('users.view');
    }
    ...

it would now look as follows:

namespace App\Models\Policies;

use App\Models\Policies\Traits\CrudPermissions;

class UserPolicy
{
    use CrudPermissions;
}

and it will automatically check for the following permissions which you would have seeded / set up in Spatie's package.

users.viewAny
users.view
users.create
users.update
users.delete
users.forceDelete
users.restore

Additionally if using the PermissionBasedAccess trait on your model, the following extra ones are taken into account

users.viewOwn (as long as you own the record)
users.updateOwn
users.deleteOwn

If the user_id column is not user_id, set that in the getOwnerKeyColumn method documented below in the Crud Access for Model section.

viewAny, create, restore & forceDelete will use the base versions only, and you would need to customise if needed yourself by setting up the permission or policy method to deal with it based on your business logic. Create and viewAny do not have Ownership within a default policy, and the restore / forceDelete are mainly only an administrative functionality.

Permission naming.

The permission naming will by default use a plural of the model name: ie User becomes users / BlogPost becomes blog_posts

Crud Access Permission Global Trait & Scope for Model

If you use the CustomD\LaravelHelpers\Traits\PermissionBasedAccess trait on your model it will look for the following Spatie permissions by default:

xxx.view, xxx.viewOwn

This works as follows:

if viewOwn is true, then it will call scopeCanRetrieveOwnRecord scope
else if view is true, then it will call scopeCanRetrieveAnyRecord scope
else it will fallback to scopeCannotRetrieveAnyRecord scope

To modify the user column, add this to the model.

    public function getOwnerKeyColumn(): ?string
    {
        return 'custom_id';
    }

to call without the scopes: use the withoutPermissionCheck modifier: eg Model::withoutPermissionCheck()->get()

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.

String Helpers

isEmail -- usage Str::isEmail('xxx') or str('xxx')->isEmail() -- will return boolean.

Array Helpers

pushBefore - will push one or more items before the specified key, or append to the end of the array if the key does not exist: PushAfter will push one or more items after the specified key

$arr = [
  'one' => 'two',
  'three' => 'four',
  'ten' => 'eleven',
];

$missing = [
  'four' => 'five',
  'six' => 'seven',
  'eight' => 'nine'
];

$new = Arr::pushBefore($arr, 'eight', $missing);
// or
$new = Arr::pushAfter($arr, 'three', $missing);

Collection Helpers

pushBefore - will push one or more items before the specified key, or append to the end of the array if the key does not exist: PushAfter will push one or more items after the specified key

$collection = collect([
  'one' => 'two',
  'three' => 'four',
  'ten' => 'eleven',
]);

$missing = [
  'four' => 'five',
  'six' => 'seven',
  'eight' => 'nine'
];

$collection->pushBefore('eight', $missing);
// or
$collection->pushAfter('three', $missing);

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:

//either 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);
}

As we are using final classes, these are immutable, if you need a cloned copy with edited values you can use the put command to create a new value object: eg:

$object->put('key','value'); //will set the key to value
$object->put('key.sub', 'valuesub' ); // will set the array key sub value to valuesub
$object->put('key', ['new' =>'yes']); //will set the array key to be ['new' => 'yes'] -- overwriting the entire array
$object->put(['key.new' => 'yes','key.maybe' => 'no']); //this will NOT override the entire key array, only set the new and maybe values in the actual value object array.
