i have two tables abc and def. i have models of these two tables named respectively Abc and Def. i Abc Model i declare these two functions.

public function child()
    {
       return $this->hasMany('Abc', 'parent');
    }

    // recursive, loads all descendants
    public function children()
    {
       return $this->child()->with('children')->orderBy('sort_order');
       
    }

    // parent
    public function parent()
    {
       return $this->belongsTo('Abc','parent');
    }

    // all ascendants
    public function parentRecursive()
    {
       return $this->parent()->with('parentRecursive');
    }

in controllers i called these functions by

    $abc = Abc::with('children')->whereNull('parent')->get();

i have implemnted n level hierarchy JSON from table through parent child relation.i have common column name in both tables. through these method i get the title column of abc table.but i want to fetch title column of def table.how we can do this??
