 Description   

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.

Hi SergSW

Could you try to write a failing test case ?

Thanks

SSW/TestBundle with the problem

Comment by SergSW [ 07/Nov/12 ]

I install the Symfony v2.0.18. and made small TestBundle.
I made schema database, by CLI "console doctrine:schema:update --force"
Result: Database schema updated successfully!
But I saw that I lost a field 'user_id' in a table 'AttachTree' (see Attach)

Adjusted example formatting, don't apologize for your English, thanks for the report!

What version of 2.1 are you using? We don't actually support 2.1 anymore. Inheritance has always worked as used in hundrets of unit-tests, this changes look quite major a bug to have been missed before. I can't really explain whats happening here.
