Laravel relationship hasMany returns null

Question

I've a relationship between two tables : chapters and modules and here they are :

class Chapter extends Model
{
    public function module()
    {
        return $this->belongsTo(Module::class, 'module_id');
    }
}

class Module extends Model
{
    protected $primaryKey = 'slug';
    public function chapters()
    {
        return $this->hasMany(Chapter::class, 'module_id');
    }
}

But when I use the relationship it always returns nothing :

$module->chapters;

Is there something that I'm missing?

You are using the wrong columns:

public function chapters()
{
    return $this->hasMany(Chapter::class, 'module_id');
}

The same goes for the module relationship:

public function module()
{
    return $this->belongsTo(Module::class, 'module_id');
}
