If you have constants like NODE_TYPE_PAGE, NODE_TYPE_BLOG etc. and you configure the behavior to use 'const' => 'node_type', the prefix list generated by ConstStratgey::listPrefixes() has NODE instead of NODE_TYPE.

Things get uglier if you have another set of constants like NODE_FOO_BAR and try use list with prefix node_foo and you get MissingEnumStrategyPrefixException.

I get the following error when I use the const strategy with enum:

Cake\Utility\Hash::get(): Argument #2 ($path) must be of type array|string|int|null, Cake\ORM\Entity given, called in /application/vendor/cakedc/enum/src/Model/Behavior/Strategy/ConstStrategy.php on line 133

The situation i experience is that while iterating through the result set of a query the $row in the beforeFind event already has been formated and is of type Cake\ORM\Entity.

I do not understand how this happens, but it can be fixed by adding the line

if ($constant instanceof Entity) return $row; after line 128 in the class ConstStrategy.

Currently we don't have this feature implemented. For now we need to take the list and use array_search to find the value to add in the conditions.

TODO: Create a way to reuse the const to create the query conditions.

/Docs/Documentation/Configuration.md states to load a helper:

$this->loadHelper('CakeDC/Enum.Enum');

My downloaded plugin doesn't include a helper.
Version v.1.0.0, installation via composer.

When I tested with PHPUnit during development, Deprecated Error occurred. It seems that Table :: table () has been deprecated since CakePHP 3.6.

Deprecated Error: App\Model\Table\FooTable::table() is deprecated. Use setTable()/getTable() instead. - /app/vendor/k1low/property-enum/src/Controller/Component/AutoSetComponent.php, line: 17
 You can disable deprecation warnings by setting `Error.errorLevel` to `E_ALL & ~E_USER_DEPRECATED` in your config/app.php. in [/app/vendor/cakephp/cakephp/src/Core/functions.php, line 310]

I would change it to
"Invalid value '$value', expected values are 'x', 'y' or 'z'."

Problem

    const SALUTATION_001 = 'Herr';
    const SALUTATION_002 = 'Frau';
    const SALUTATION_003 = 'Firma';
    const SALUTATION_004 = 'Herr und Frau';
    const SALUTATION_005 = 'Frau und Herr';
    const SALUTATION_006 = 'Frau und Frau';
    const SALUTATION_007 = 'Herr und Herr';
    const SALUTATION_008 = 'Eheleute';
    const SALUTATION_021 = 'Firma mit Ansprechpartner';
    //...
        $this->addBehavior('CakeDC/Enum.Enum', ['lists' => [
            'xml_kundendaten_adresse_anrede' => [
                'strategy' => 'const',
                'prefix' => 'SALUTATION',
                'field' => 'Xml_Kundendaten_Adresse_Anrede',
            ],
        ]]);

Error

Error CakeDC\Enum\Model\Behavior\Exception\MissingEnumConfigurationException

Workaround

        // Note that BOTH have to be set, else it throws exceptions once in _call()  and once in enum()
        $this->addBehavior('CakeDC/Enum.Enum', ['lists' => [
            'xml_kundendaten_adresse_anrede' => [
                'strategy' => 'const',
                'prefix' => 'SALUTATION',
                'field' => 'Xml_Kundendaten_Adresse_Anrede',
            ],
            'Xml_Kundendaten_Adresse_Anrede' => [
                'strategy' => 'const',
                'prefix' => 'SALUTATION',
                'field' => 'Xml_Kundendaten_Adresse_Anrede',
            ],
        ]]);

Question

Is there a reason the list keys are being inflected around inside the behavior?

Would having an emum helper to pull the enum configuration into a view be useful or is there a better way of doing this?

Hey :)

I noticed you have a branch ready for 3.6 support, what is missing from it so that it can be released? Can we help?

It seems packagist webhook has not been setup for the repo. Using dev-master gives old commit 631b8d5.

Currently this project does not support CakePHP 4.x, is this something you are looking to do?

Hi,
I'm sorry but I have another problem after migration my application which uses Enum form Cake 3 to Cake 5:

I have an Entity e.g. Article which contains an enum attribute visibility.
The enum is defined as follows:

$this->addBehavior('CakeDC/Enum.Enum', ['lists' => [ 'visibility' => [ 'strategy' => 'const', 'prefix' => 'VISIBILITY', 'field' => 'visibility', 'translate' => true ] ]]);

When I read an existing entity and modify it in the controller,

$article = $this->Articles->get($id); $article->count_viewed = $article->count_viewed + 1; $this->Articles->save($article));

the save operation is throwing a TypeError

"array_key_exists(): Argument #1 ($key) must be a valid array offset type"
in ROOT/vendor/cakedc/enum/src/Model/Behavior/EnumBehavior.php at line 299

As far as I see the problem originates by the fact that after reading the visibility attribute is an object(Cake\ORM\Entity) but when I save the value a string is expected.
Because after

$article->visibility = $article->visibility->value;

saving ist possible.

I wonder if it would be possible to make the Const Type allow for integers as values. So for example:

class SampleTable extends Table {

    const TYPE_PLATFORM = 0;
    const TYPE_USER = 1;
    const TYPE_DEVICE = 2;

    public function initialize(array $config) {
        parent::initialize($config);

        $this->addBehavior('CakeDC/Enum.Enum', ['lists' => [
            'type' => [
                'strategy' => 'const',
                'prefix' => 'TYPE'
            ]
        ]]);
...

And show PLATFORM, USER and DEVICE in lists but put the integer in the db. I can get this working currently but its a bit hacky. I can add applicationRules => false and having array_flip($this->Samples->enum('type'))

Maybe I need to make a custom strategy? ;-)

It is working fine in CakePHP3 and enum package version '1.4.0'. I upgraded the project from CakePHP3 to CakePHP4. I am using version 2.1.0 for CakePHP4

I get the following error when I use the const strategy with enum:

ERROR: [InvalidArgumentException] Invalid Parameter { "label": null, "prefix": "TYPE", "value": null }, should be dot separated path or array. in /var/www/html/vendor/cakephp/cakephp/src/Utility/Hash.php on line 65

It can be fixed by adding the below after line 128 in the class ConstStrategy.

if ($constant instanceof Entity) { return $row; }

I think this issue this same as #55. Can you please provide support for v2.1.0.

Currently ConstStrategy::enum() does the process of extracting enum list on each call.

Given the use of reflection and multiple iterations of array manipulation and callbacks usage, the whole operation is non trivial and it would be better the lists were cached to avoid the overhead on subsequent requests for the same list.

I used CakeDC/Enum in my project and migrated to CakePHP 5.0 and now have problems with the implementation of the ConstStrategy.

In the branch 3.next-cake5 @arusinowski introduced with commit 0447fec5b1b6eb883b79a257920671f630bb4c74
an changed the following lines:

$query->formatResults(function (CollectionInterface $results) { return $results->map(function ($row) { if (is_string($row) || !$row) { return $row; }
to

$query->formatResults(fn(CollectionInterface $results) => $results ->map(function (EntityInterface $row): EntityInterface {

But as the $row could also be an array if you have a non hydrated result or if you call the exists(ID) function on a modell, this does not work as expected.

This change has not been merged with the master branch.
Therefore the fix #55 is actually not relevant for the master branch but only for the 3.next-cake5 branch.

@arusinowski : Is it possible for you to fix this? Thanks.

Is it possible to use different name for saving and displaying for multilingual purposes?

It would be nice to have enum rules in validationDefault per config

I am happy to contribute the docs.

I only need some briefing on :

1. what does this Enum roughly do?
2. how do I create the .rst files and get it up on readthedocs.org?

I can be on the irc channe #cakephp or #FriendsOfCakel. And we can talk this through.
