Answer 1

Read up a bit on query builder. It's easier and different than a sql query. No need for join conditions.

This (for starters):

$qb->leftjoin('PriceOrQuality\POQBundle\Entity\Tag','t', 'WITH', 'et.tag = t.id');

Should just be:

$qb->leftJoin('et.tag','t');

There might be more problems but that will get you started. http://docs.doctrine-project.org/en/latest/reference/query-builder.html

Answer 2

Found the issue.

I had a //@todo after the meta definition and before the class definition. Apparently that screwed up the mapping, as it was not mapped in doctrine.

Moving the //@todo and rerunning the mapping fixed the problem.

For whomever finds this question with similar problems try running:

php app/console doctrine:mapping:info

It will show you if you have problems in the mapping structure in doctrine

Thanks for your time guys.
