If you need to do something every time a model event is fired then it probably makes sense to put the code inside the model class itself. If it's something separate (E.g. a registration or password reset email), then I would use an event subscriber class and register it where it's needed.

Edit: Eloquent has built in observers now, and I've put a pull request in to allow the default connection to be retrieved statically, so the BaseModel class probably won't be needed soon enough.

nice, what about paginating Eloquent results stand-alone ?
I'm trying to use Illuminate\Pagination but it need Environment, Views, and I could not make it work "stand-alone".

So basically I use:

    $post->skip(offset)->take(limit)->get();

How to make it work with:

$post->paginate(limit);
...
$post->paginate(limit)->links(); 

?
