Add a yaml example for specifying an identifier.

Closes #639

[trsteel88]

Actually, I don't think this is correct. I still get the warning Unable to generate an IRI for the item of type \"App\\Api\\Model\\MyNonDoctrineModel\"

[antograssiot]

Do you have a getter on your property and enable the get on item operation ?

[trsteel88]

Yes.

final class MyNonDoctrineModel
{
    /**
     * @var string
     */
    private $id;

    /**
     * @var Organisation
     */
    private $organisation;

    /**
     * @var Template
     */
    private $template;

    /**
     * @var float
     */
    private $price;

    public function __construct(Organisation $organisation, Template $template)
    {
        $this->organisation = $organisation;
        $this->template = $template;
        $this->id = $this->organisation->getId().'-'.$this->template->getId();
    }

    public function getId(): string
    {
        return $this->id;
    }

My resource looks like this

App\Api\Model\MyNonDoctrineModel:
    properties:
        identifier: [id]
    attributes:
        access_control: "is_granted('ROLE_USER')"
    itemOperations:
        get:
            method: GET
            path: /organisations-templates/{id}
            defaults:
                _api_receive: false
            controller: App\Api\Action\OrganisationTemplatePrice\ViewAction
    collectionOperations:
        get:
            method: GET
            path: /organisations-templates
            controller: App\Api\Action\OrganisationTemplatePrice\ListAction

It's definitely a configuration issue with defining the identifiers because what I have configured are not coming through when I do a dump within IdentifiersExtractor.php

If I override the array of identifiers within that code it works.

[antograssiot]

isn't that

App\Api\Model\MyNonDoctrineModel:
    properties:
        id:
            identifier: true
...

instead ?

[trsteel88]

I'm away from my computer at the moment. But I am pretty sure I tried that and it didn't work either.

[trsteel88]

You were right @antograssiot. Thanks!

Thanks a lot @trsteel88 and @antograssiot, this kind of enhancements in the docs are very helpful!
