Extending Eloquent models, more magic methods - php

Question

Situation: In my work they have conventions on their database, table and column names, which are a bit long and repetitive. Being used to Eloquent I figured it wouldn't be much trouble to reimplement __get and __set methods, and not making lots of getters. Something like this (toConvention implements company's conventions):
use Illuminate\Database\Eloquent\Model;
class CompanyModel extends Model {
public function __get($key){
return $this->getAttribute($this->toConvention($key));
}
public function __set($key){
return $this->setAttribute($this->toConvention($key));
}
}
Which works well, for retrieving attributes, but not for retrieving relationships. Here are the implementations:
use App\CompanyModel as Model
class Location extends Model
{
protected $table = 'tablename';
protected $primaryKey = 'primarykeycolumn';
//...
public function comissionCurrency(){
return $this->belongsTo('App\Currency', 'foreign', 'other');
}
}
use App\CompanyModel as Model
class Currency extends Model
{
protected $table = 'tablename';
protected $primaryKey = 'primarykeycolumn';
//...
}
When requesting for attributes, like $location->name, or $location->comission_currency_id everything works as expected, retrieving the corresponding column name. But when I try to retrieve the belongsTo relationship, after using toSql() I see almost the correct query formed: select * from table where table.column is null the is null part should be comparing with the corresponding id.
I know it's due to my implementation, because when I use Illuminate\Database\Eloquent\Model everything works ok. Funny thing is that when I use Eloquent's model on the child model and the reimplemented on the other, it works to (but I'm not able to use my magic methods in the child model, in the parent one fetched from the relationship I can...)
I haven't figured out which method to reimplement to make this work by reading Eloquent's code, any ideas, or suggestions?
Thanks in advance.
