Datamapper : One To Many

[quote author="WanWizard" date="1298235727"]Datamapper is object based, so every query starts from the current object.

What you want is not to get a single object, but all objects for a model, and for each of these objects, fetch all childs. This functionality is not in Datamapper because it would crash your application with an out-of-memory error very quickly, if it has to instantiate all those objects.

You need to "flatten" the result, as you would do with a normal JOIN query. That requires the include_related() method, but currently that is limited to $has_one relations. However, I don't think it breaks on a $has_many relation. You could try to comment the error message in line 4656, and use

Code:

$c = new Chain();
$c->include_related('restaurant')->get();
check_last_query();

In which file should I comment the error message? is it on the datamapper file stored in the application/libraries? Thanks,
Denis.
