The parent method is already using defaultKeyName.

In the Query\Builder, we don't know the model. We cannot guess the type of the _id field. It's better not doing any transformation.

The ObjectId cast should not be used with anything else than ObjectId key type. Otherwise there is a mismatch in the type when using Model->getKey() to query the database.
This impacts queries using the query builder and relations.

This must be revisited to support SQL<->MongoDB relations.

The (array) $id cast works until it is applied to an object.
(array) 1 => [1]
(array) (new ObjectId()) => ['oid' => ... ]| foreach ($results as $result) { | ||
| foreach ($result->$foreign as $item) { | ||
| $dictionary[$item][] = $result; | ||
| $dictionary[(string) $item][] = $result; |

Casts the ObjectId to a valid array-key.
The type of $dictionary can't be changed to SplObjectStorage it's used to search on values in Laravel's BelongsToMany::match.
Fortunately, the key is stringified before being searched.

This is a feature that needs to be kept: Allow to use a custom 'id' field as id.

Developers should work with
ObjectIdfor the_idfield.But if the
Model::$keyTypeisstring, they can use a cast to convert database values (ObjectId) tostringwhen reading, andstringtoObjectIdwhen setting the value for the database (as document value or for a query).Changes are TDD: I updated to code to make the tests work as much as possible.
Only the model key is casted because this where there is an issue. But could opt for a more generic approach an apply the cast to all the values sent to Eloquent builder (ie: linked to a model).
