Hello,
I have a problem with ManyToOne relation.
For example, I have main object with three child and when I execute on main
object
$em = $this->getDoctrine()->getManager();
$em->merge($data);
$em->flush();
I sometimes get ERROR message like:
*Uncaught PHP Exception
Doctrine\DBAL\Exception\UniqueConstraintViolationException: "An exception
occurred while executing 'UPDATE*
I get this ERRROR message not for all main object and not for all child.
For example, first update child object is ok but in second I get Error.
SQL prepared by doctrine:
UPDATE child_table SET id = ?, name = ?, object_name = ?, object_size = ?
WHERE id = ?' with params ["2", "test Name object 2", "test name object 2",
"1234", 3]
In this sql the doctrine tries update object with id=3 using data from
object with id = 2.
I am using 10.4 PostgreSQL and:
doctrine/annotations v1.2.7
doctrine/cache v1.4.2
doctrine/collections v1.3.0
doctrine/common v2.7.3
doctrine/dbal v2.5.13
doctrine/doctrine-bundle v1.5.2
doctrine/doctrine-cache-bundle v1.0.1
doctrine/inflector v1.0.1
doctrine/instantiator 1.0.5
doctrine/lexer v1.0.1
doctrine/orm v2.5.14
What is the reason of this problem?
