[quote author="WanWizard" date="1330099200"]To start with the all_to_array() question: if you check the array extension, you'll see that the to_array() method checks both the has_one and has_many arrays to see if the property name is an related object. Perhaps you can debug that and see why it doesn't work?[/quote]
I have found out why it doesn't work (for me).

In to_array() (which is called by all_to_array()) the $object->fields are taken. Those do not include has_one or has_many. The array extension then does this:

Code:

if(array_key_exists($f, $object->has_one) || array_key_exists($f, $object->has_many))

Where $f is the current field. The thing is the $fields do not include has_many or has_one. It does take has_one, because $fields is the database fields and a has_one has a database field, whereas a has_many has a database join table.

in_array() does have the option to give the fields as a parameter instead of defaulting to the fields of the Object you are calling in_array on. Thus I 'fixed' this by giving the names of the has_many objects as the parameter. Another way would be to overload in_array and get it to check fields and has_many arrays.

The way the function works is probably intended, but I didn't get it at first. Thanks!

[quote author="WanWizard" date="1330099200"]A constructor should only be called when constructing the object, so you are right in that it should only be called once. However, internally an object is constructed for each record in the result, so it's logical that you will see a call to the constructor in get() operations, as new objects of your model are instantiated.[/quote]
Ah! So that's how... right, moving on, nothing to see here. I blame friday-tired brain.

[quote author="WanWizard" date="1330099200"]As for your last question, assuming that 'friend' is a related model, it will only exist if related objects have been fetched, which is never the case in a model constructor (as you haven't even fetched the record itself at that point).[/quote]
This makes sense and I was able to find this out myself now that I got in_array() working for myself. It makes understanding the Datamapper much easier. I will just have to call a method to populate the friends after the Character is instanced.

EDIT: Here is a quick and dirty addition to to_array, after row 45.

Code:

foreach($object->has_many as $key => $value)
  {
   $fields[$key] = $key;
