[DDC-2119] Problem with inheritance type: INHERITANCE_TYPE_NONE and INHERITANCE_TYPE_TABLE_PER_CLASS

Mon, 8 Apr 2013 20:43:37 +0000

I tried to create inheritance entities with save policy table per class.
Simple fileds was created normally, but a field with ManyToOne type was lost.

I had found a solution.

In Doctrine\ORM\Tools\SchemaTool
...

private function _gatherRelationsSql($class, $table, $schema)
    {
        foreach ($class->associationMappings as $fieldName => $mapping) {

           // if (isset($mapping['inherited'])) { // - old version

	/**
             * SSW
             * It's the solution
             */
	if (isset($mapping['inherited']) && !$class->isInheritanceTypeNone() && !$class->isInheritanceTypeTablePerClass() ) {
                continue;
            }            

            $foreignClass = $this->_em->getClassMetadata($mapping['targetEntity']);
...

But it was enough. In DQL query a simple query was made wrong.

I had found a solution again.
In Doctrine\ORM\Query\SqlWalker
...

public function walkSelectExpression($selectExpression)
...

                // original => if (isset($mapping['inherited'])){
                // It's the solution
                if (isset($mapping['inherited']) && !$class->isInheritanceTypeNone() && !$class->isInheritanceTypeTablePerClass()) {
                    $tableName = $this->_em->getClassMetadata($mapping['inherited'])->table['name'];
                } else {
                    $tableName = $class->table['name'];
                }
...

This problems are topical for inheritance type: INHERITANCE_TYPE_NONE and INHERITANCE_TYPE_TABLE_PER_CLASS.

I don't know, may be my solutions are wrong. But some programmers want to correctly work with INHERITANCE_TYPE_TABLE_PER_CLASS.

Sorry for my english.
