How to get department name of a module in Laravel models - php

Question

I am trying to get the department that a module is part of in laravel like:
This is my Faculty class:
<?php
class Faculty extends Eloquent {
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'faculty';
public $timestamps = false;
/**
* Whitelisted model properties for mass assignment.
*
* #var array
*/
protected $primaryKey='facultyid';
protected $fillable = array('facultyname', 'facultyshort');
public function departments()
{
return $this->hasMany('Departments', 'facultyid');
}
}
This is my Departments class
<?php
class Departments extends Eloquent {
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'departments';
public $timestamps = false;
/**
* Whitelisted model properties for mass assignment.
*
* #var array
*/
protected $primaryKey='departmentid';
protected $foreignKey='facultyid';
protected $fillable = array('departmentname', 'departmenthead', 'facultyid');
public function modules()
{
return $this->hasMany('Modules', 'departmentid');
}
public function faculty()
{
return $this->belongsTo('Faculty', 'facultyid');
}
}
and finally this is my modules class:
<?php
class Modules extends Eloquent {
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'modules';
protected $foreignKey='departmentid';
public $timestamps = false;
/**
* Whitelisted model properties for mass assignment.
*
* #var array
*/
protected $primaryKey='mid';
protected $fillable = array('mfulltitle', 'mshorttitle', 'mcode',
'mcrn', 'mfieldofstudy', 'mcoordinator','mlevel',
'mcredits', 'melective', 'departmentid');
public function department()
{
return $this->belongsTo('Departments', 'departmentid');
}
public function classes()
{
return $this->hasMany('Classes', 'moduleid')->orderBy('classid', 'ASC');
}
}
I have tried doing something like this:
#foreach(Modules::where('melective', '=', 1)->get() as $mod)
{{$mod->mshorttitle}} belongs to department: {{ $mod->department->departmentname }}
#endforeach
But it does not work, does anyone have any idea on how to do this?
==============================
SOLUTION
After a bit of work i figured it out
in Department class i added the following function:
public function name()
{
return $this->departmentname;
}
and i changed the code to the following:
#foreach(Modules::where('melective', '=', 1)->get() as $mod)
{{$mod->mshorttitle}} belongs to department: {{ $mod->department->name() }}
#endforeach
