Extends Opportunity entity with a collection called product interests

I’ve tried to add one-2-many relationship to the existing Opportunity entity. The collection is called product interest collection. I also defined some fields in ProductInterest entity.

I also tried to extend Opportuniy entity by extending Oro\Bundle\SalesBundle\Entity\Opportunity.

PHP

<?php namespace Acme\Bundle\SalesBundle\Entity; use Oro\Bundle\SalesBundle\Entity\Opportunity as OpportunityOROCRM; use Acme\Bundle\OrderBundle\Entity\ProductInterest; class Opportunity extends OpportunityOROCRM { /** * @var ProductInterest[]|Collection * * @ORM\OneToMany(targetEntity="Acme\Bundle\OrderBundle\Entity\ProductInterest", mappedBy="opportunity",cascade={"all"}) * @ConfigField( * defaultValues={ * "importexport"={ * "full"=true * }, * "dataaudit"={"auditable"=true}, * } * ) */ protected $productinterests; /** * @return ProductInterest[]|Collection */ public function getItems() { return $this->productinterests; } /** * @param float $items * * @return ProductInterest */ public function setItems($items) { $this->items = $productinterests; return $this; } } ?>

<?php   namespace Acme\Bundle\SalesBundle\Entity;   use Oro\Bundle\SalesBundle\Entity\Opportunity as OpportunityOROCRM; use Acme\Bundle\OrderBundle\Entity\ProductInterest;   class Opportunity extends OpportunityOROCRM {         /**      * @var ProductInterest[]|Collection      *      * @ORM\OneToMany(targetEntity="Acme\Bundle\OrderBundle\Entity\ProductInterest", mappedBy="opportunity",cascade={"all"})      * @ConfigField(      *      defaultValues={      *          "importexport"={      *              "full"=true      *          },      *          "dataaudit"={"auditable"=true},      *      }      * )      */     protected $productinterests;           /**      * @return ProductInterest[]|Collection      */     public function getItems()     {         return $this->productinterests;     }       /**      * @param float $items      *      * @return ProductInterest      */     public function setItems($items)     {         $this->items = $productinterests;           return $this;     } }   ?>

PHP

<?php namespace Acme\Bundle\SalesBundle\Form\Extension; use Symfony\Component\Form\AbstractTypeExtension; use Symfony\Component\Form\FormBuilderInterface; use Oro\Bundle\SalesBundle\Form\Type\OpportunityType; class OpportunityTypeExtension extends AbstractTypeExtension { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add( 'items', 'oro_address_collection', array( 'label' => '', 'type' => 'Acme\Bundle\SalesBundle\Form\Type\ProductInterestType', 'required' => false, 'options' => array('data_class' => 'Acme\Bundle\OrderBundle\Entity\ProductInterest') ) ); } /** * Returns the name of the type being extended. * * @return string The name of the type being extended */ public function getExtendedType() { return OpportunityType::class; } }

<?php   namespace Acme\Bundle\SalesBundle\Form\Extension;   use Symfony\Component\Form\AbstractTypeExtension; use Symfony\Component\Form\FormBuilderInterface; use Oro\Bundle\SalesBundle\Form\Type\OpportunityType;     class OpportunityTypeExtension extends AbstractTypeExtension {       public function buildForm(FormBuilderInterface $builder, array $options)     {         $builder->add(             'items',             'oro_address_collection',             array(                 'label'    => '',                 'type'     => 'Acme\Bundle\SalesBundle\Form\Type\ProductInterestType',                 'required' => false,                 'options'  => array('data_class' => 'Acme\Bundle\OrderBundle\Entity\ProductInterest')             )         );     }       /**      * Returns the name of the type being extended.      *      * @return string The name of the type being extended      */     public function getExtendedType()     {         return OpportunityType::class;     }      }

However, I cannot make it work. The system doesn’t detect the extended Opporunity entity at all. It always throw me the following error.

[2018-05-08 10:04:55] request.CRITICAL: Uncaught PHP Exception Symfony\Component\PropertyAccess\Exception\NoSuchPropertyException: “Neither the property “items” nor one of the methods “getItems()”, “items()”, “isItems()”, “hasItems()”, “__get()” exist and have public access in class “Oro\Bundle\SalesBundle\Entity\Opportunity”.” at /var/www/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php line 486 {“exception”:”[object] (Symfony\\Component\\PropertyAccess\\Exception\\NoSuchPropertyException(code: 0): Neither the property \”items\” nor one of the methods \”getItems()\”, \”items()\”, \”isItems()\”, \”hasItems()\”, \”__get()\” exist and have public access in class \”Oro\\Bundle\\SalesBundle\\Entity\\Opportunity\”. at /var/www/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php:486)”} []

Can anyone tell me what’s the correct way of extends Opporunity entity and a new sub collection to it?

Doctrine entities cannot be extended from another bundles in case they are not mapped superclasses.

However OroPlatform provides possibility to add fields or relations to entities marked as Extended without modification the original entities using schema migrations.

As an example you can check OroPromotionBundleInstaller:: addAppliedCouponsToOrder() method.

To know more about schema migration check the migration bundle documentation OroMigrationBundle/README.md

To know more about Extended entities check this article Modify entities using migration scripts.
