Hi!
When using relations I can grab all the comments for lets say a Blog post by doing
$post = Model_Post::find($id);
$comments = $post->comments;
// do something with the comments...
Given there are comments to the post it will return an array of Comment objects. Is there any way to do an order_by using the ORM or do I have to go through the query builder to do this?
Take a look at the examples in the docs: http://fuelphp.com/docs/packages/orm/crud.html#read
It's only supported for eager loading, lazy loading as in your example just grabs the relation without additional conditions.
