why not? Just don't forget to pass model member in view.

But what would i put in my get_url() method? How can I get what model instance it is?

In your Eloquent model add the following variable to the top. This will add a new field to your model.

protected $appends = ['url'];

Continue to add a new accessor method to the same model

public function getUrlAttribute()
{
	return URL::to('profile/' . $this->id);
}

This is called an accessor. Read more about what accessors are here: http://laravel.com/docs/eloquent#accessors-and-mutators

You can use it by passing the model data to the view and calling the new field.

<a href="{{ $user->url }}">{{ $user->name }}</a>

I hope this helped you.
