How do I make Propel retain associative format with singular selects?

问题

I have the following Criteria in Propel:

$q = \UserQuery::create();
$q->select(array('id', 'name'));
$q->orderBy('name');
$q->setOffset($offset);
$q->setLimit($limit);
return $q->find();

This works fine, and gives me a two-dimensional array with id and name keys in the inner array, i.e.

array( array("id" => 1, "name" => 'A'), array("id" => 2, "name" => 'B') )

However, if I run the following:

$q = \UserQuery::create();
$q->select(array('id'));
$q->orderBy('id');
$q->setOffset($offset);
$q->setLimit($limit);
return $q->find();

It gives me a one-dimensional array with no column keys, only indexes, i.e.

array(1, 2)

If I use the PropelArrayFormatter:

$q = \UserQuery::create();
$q->select(array('id'));
$q->orderBy('id');
$q->setOffset($offset);
$q->setLimit($limit);
$q->setFormatter('PropelArrayFormatter');
return $q->find();

It hydrates the entire object with null values:

array( array("id" => 1, "name" => null, "hash" => null, "last_login" => null), array("id" => 2, "name" => null, "hash" => null, "last_login" => null) )

If I add:

$q->setFormatter('PropelArrayFormatter');

Then I get:

PHP Notice:  Undefined offset: 2 in BaseUser.php on line 1518
PHP Notice:  Undefined offset: 3 in BaseUser.php on line 1519
PHP Notice:  Undefined offset: 4 in BaseUser.php on line 1520

PHP Notice:  Undefined offset: 12 in BaseUser.php on line 1528
PHP Notice:  Undefined offset: 13 in BaseUser.php on line 1529
PHP Notice:  Undefined offset: 14 in BaseUser.php on line 1530
PHP Notice:  Undefined offset: 15 in BaseUser.php on line 1531
PHP Notice:  Undefined offset: 16 in BaseUser.php on line 1532
PHP Notice:  Undefined offset: 17 in BaseUser.php on line 1533
PHP Notice:  Undefined offset: 18 in BaseUser.php on line 1534
PHP Notice:  Undefined offset: 19 in BaseUser.php on line 1535
PHP Notice:  Undefined offset: 20 in BaseUser.php on line 1536

And nothing is returned. I have also tried PropelSimpleArrayFormatter, and it never returns an associative array:

$q->setFormatter('PropelSimpleArrayFormatter');

The result:

PropelArrayCollection::__set_state(array(
   0 => '123',
   1 => '126',
   2 => '133',
   3 => '242',
   4 => '256',
   5 => '272',
   6 => '283',
   7 => '284',
   8 => '474',
   9 => '617',
))

回答1:

Propel uses per default SimpleArrayFormatter if you limit the selected columns, which does some handy stuff as you've seen.

If you want to stick with the normal behavior, set the normal ArrayFormatter as Formatter:

$q->setFormatter('\Propel\Runtime\Formatter\ArrayFormatter');
