Hello everyone!

I am trying to achieve something like a morph relation but in a different manner. I don't like the database structure that the Eloquent's morph functionality forces and I am trying to do it "the opposite way". My DB structure is:

Orders

• id
• file_group_id
• ... many more

Contacts

• id
• file_group_id
• ...many more

FileGroups

• id
• title

Files

• id
• file_group_id
• path

As you can see Contact and Orders can have both a FileGroup attached to them.

Here is my FileGroup model:

class FileGroup extends Eloquent {

	protected $guarded = array('id');

	public function files() {
		return $this->hasMany('File');
	}

    public function order() {
        return $this->hasOne('Order');
    }

    public function contact() {
        return $this->hasOne('Contact');
    }

    public function attachee() {
        if ( $this->order ) {
            return $this->order();
        }

        if ( $this->contact ) {
            return $this->contact();
        }

        return $this;
    }
}

What I am trying to do here is the "attachee" method. I guess you can get an idea what I am trying to do, but I am obviously doing it the wrong way. I just want attachee() to return either an Order, a Contact, or nothing, depending on whether the FileGroup is attached to any of these. I don't think Eloquent has a built-in mechanism for achieving this. How would you recommend me to approach? Thank you for your help!
