Doctrine2 ODM限制不起作用/ mongodb

Question

I'm trying to skip and limit results, but I don't even get it to limit the results.

here's my code

    $limit=5;
    $fooQueryBuilder = $this->mongo->getManager()->createQueryBuilder('CustomCoreBundle:Foo');
    $foos=$fooQueryBuilder->limit($limit)->getQuery()->execute();

    var_dump(count($foos));
    exit;

and the var_dump returns

int(321235)

and that's equal to all entities in the database, what am I doing wrong ?

$this->mongo->getManager() 

is instance of

Doctrine\ODM\MongoDB\DocumentManager

and the builder is instance of

Doctrine\ODM\MongoDB\Query\Builder"

I just don't understand what's wrong, thanks for any hint

Answer 1

So, I found out the answer myself

it is working !

and I learned:

when you count() a cursor, no matter what the query, it returns the amount of all entities in database.

So my check to count the cursor to see if the limit is working was simply wrong
