在Sonata电子商务中创建产品-没有可用的对象类型

Question

I have a problem with Sonata e-commerce, with creating a Product. I follow sonata documentation and other posts related with that and I constantly get message "No object types available"

My files looks like:

product.yml

services:
    sonata.ecommerce_demo.product.bowl.manager:
        class: Sonata\ProductBundle\Entity\ProductManager
        arguments:
            - Application\Sonata\ProductBundle\Entity\Bowl
            - @doctrine

    sonata.ecommerce_demo.product.bowl.type:
        class: Application\Sonata\ProductBundle\Provider\BowlProductProvider
        arguments:
            - @serializer

sonata_product.yml

sonata_product:
    products:
        sonata.ecommerce_demo.product.bowl:
            provider: sonata.ecommerce_demo.product.bowl.type
            manager: sonata.ecommerce_demo.product.bowl.manager

Entity.Product.xml

<?xml version="1.0" encoding="UTF-8"?>
<serializer>
    <!-- This file has been generated by the SonataEasyExtendsBundle: https://sonata-project.org/bundles/easy-extends -->
    <class name="Application\Sonata\ProductBundle\Entity\Product" exclusion-policy="all" xml-root-name="_product">
        <discriminator-class value="sonata.ecommerce_demo.product.bowl">Application\Sonata\ProductBundle\Entity\Bowl</discriminator-class>
        <property xml-attribute-map="true" name="id" type="integer" expose="true" since-version="1.0" groups="sonata_api_read,sonata_api_write,sonata_search"/>
    </class>
</serializer>

    {
        $this->id = $id;
    }
}

use Sonata\ProductBundle\Entity\BaseProduct as BaseProduct;

    protected $id;

    /**
     * Get id.
     *
     * @return int $id

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

    },

I also check sonata sandbox on github and I can't find what I'm missing.

I'm using symfony 2.8 and php 7.2

Answer 1

After a lot of researches I finally found the solution. Developers of sonata ecommerce remove getClass() method from ProductAdmin.php. This class is only available in branch 1.x and not on the heigher branches.

Original getClass() method looks like:

/**
 * @return string
 */
public function getClass()
{
    if ($this->hasSubject()) {
        return get_class($this->getSubject());
    } elseif ($class = $this->getProductClass()) {
        return $class;
    }
    return parent::getClass();
}

and it causes some errors, so the solution is to add slightly modified class, without second condition. Add this to ProductAdmin.php.

/**
 * @return string
 */
public function getClass()
{
    if ($class = $this->getProductClass()) {
        return $class;
    }

    return parent::getClass();
}

I found the solution on sonata ecommerce github .
