I have installed Sonata admin project in Symfony 3.2.* version. Components that are being used in my project from composer.json file are as following:

Details

I am using translation bundle. So in my form, for each field I am having that fields for two languages. The form is rendering with multi-language options perfectly. But when I submits the form, I am getting below error:

Could not determine access type for property "translations".

Stack Trace in vendor\symfony\symfony\src\Symfony\Component\PropertyAccess\PropertyAccessor.php at line 649

} elseif (self::ACCESS_TYPE_MAGIC === $access[self::ACCESS_TYPE]) {
        $object->{$access[self::ACCESS_NAME]}($value);
    } elseif (self::ACCESS_TYPE_NOT_FOUND === $access[self::ACCESS_TYPE]) {
        throw new NoSuchPropertyException(sprintf('Could not determine access type for property "%s".', $property));
    } else {
        throw new NoSuchPropertyException($access[self::ACCESS_NAME]);
    }

回答1:


Most of the time this error gets thrown when you forget to initialize a collection in the constructor of your entity class.

Look at your entity class. You need to add

 $this->translations = new ArrayCollection();

to the constructor.

More generally, PropertyAccess is responsible for calling the setters/getters of your entity so usually it is a problem related to your entity class and not your form type.
