在laravel中获取具有雄辩关系的列列表

Question

I want to get column list with Eloquent relation in laravel. When I use this comman

 $columns = Schema::getColumnListing('news');

Result is all fields of news table but I want to get relation fields for CategoryNews table.

News model:

public function NewsCategories()
   {
    return $this->belongsTo('App\CategoryNews');
   }

CategoryNews model:

public function News()
  {
    return $this->hasMany('App\News');
  }

Answer 1

You should be able to do something like this:

$columns = Schema::getColumnListing($news->NewsCategories()->getRelated()->getTable()));

Using getRelated() method you are getting related object for relationship (in your case it's App\\CategoryNews ) and now using method getTable() you can get table name for this model and you can use this table name for getColumnListing() method.
