Is there any way to limit the results of getMany, or do I need to need to use another function to do this?

$c = $modx->newQuery('ClassName');
$c->limit(10);
$results = $obj->getMany('Alias',$c);

Does newQuery always have to be provided the ClassName and getMany the alias? I’m still trying to figure out when and how the aliases come into play.

Yes, for getMany/getOne.

An alias is the alias of the class name within relation to an object. This is useful in instances where you have more than one field that uses a class name, ie:

- Alias: CreatedBy, Class: modUser
- Alias: EditedBy, Class: modUser
- Alias: PublishedBy, Class: modUser

eg, on Resources. They are then grabbed by:

$createdBy = $resource->getOne('CreatedBy');
$editedBy = $resource->getOne('EditedBy');
$publishedBy = $resource->getOne('PublishedBy');

Thanks Shaun. So if you don’t have any duplicate names, can I always use the classnames instead of the alias? Or are there certain methods that require one or the other?

You have to use the alias to specify relations, as declared in the maps generated from the schema.
