注意：Symfony 中数组到字符串的转换

Question

I have problem with my code. I have an entity:

    }

and my method in MenuRepository :

    /**
         * @param Menu $menu
         * @return mixed
         */
        public function addMenu(Menu $menu)
        {
            try {

                $this->getEntityManager()->beginTransaction(); // suspend auto-commit
                $this->getEntityManager()->persist($menu);
                $this->getEntityManager()->flush($menu);
                $this->getEntityManager()->commit();


                $this->getEntityManager()->detach($menu);


                return $menu;
            } catch (\Exception $e) {
                throw new RepositoryException($e->getMessage());
            }

When i have add new record to database, i got error:

In MenuRepository.php line 79:
Notice: Array to string conversion

line 79 is:

    throw new RepositoryException($e->getMessage());

My Command code to add new record:

    $menuData = new Menu();
    $menuData->setStatus(1);
    $menuData->setData([]);
    $dataPool = new DataPoolEntity();
    $dataPool->setIsReadonly(true);
    $dataPool->setName("qwerty");
    $dataPool->setDescription("tester");
    $dataPool->setChildren(null);
    $menuData->setDataPool($dataPool);
    $menuData->setPathString('qwertty');
    $menuData->setPriority(1);
    $menuData->setDisplayChildren(true);
    $menuData->setDisplay(true);
    $menuData->setIdentifier("qwery");
    $menuData->setInheritancePriority(1);

In my var.log i have this message:

[2019-12-21T20:35:49.313897+01:00] console.ERROR: Error thrown while running command "sdk:menu:create -vvvvv". Message: "Notice: Array to string conversion" {"exception":"[object] (CP\\Model\\Exception\\RepositoryException(code: 0): Notice: Array to string conversion at C:\\Users\\rever\\PhpstormProjects\\cp-base\\vendor\\cp\\web-core\\src\\Model\\Repository\\MenuRepository.php:79)","command":"sdk:menu:create -vvvvv","message":"Notice: Array to string conversion"} []

I don't have idea what is wrong with my code :( For several hours I have been looking for the cause of the error and I can't deal with it, that's why I wrote. I have already tried to add some value rigidly, but it will give the same problem.

Answer 1

your data are defined in your entity like this:

/**
 * @var array
 *
 * @ORM\Column(name="data", type="text", length=65535)
 */
protected $data = [];

but in your @var you specified array , so you can change the column type to array like this:

/**
 *
 * @ORM\Column(name="data", type="array")
 */
protected $data = [];

This will result in a longtext field with comment "(DC2Type:array)" so Doctrine knows how to handle it. It will store a serialized array.
