Get all data where pivot id (Laravel)

Is there the best way/the simplest way to get all data where pivot? I tried this $article = Article::with('category')->wherePivot('category_id', $category)->get(); but i got error

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'pivot' in 'where clause' (SQL: select * from `articles` where `pivot` = category_id)

The relation is many to many

Article

• id
• content

public function category(){
        return $this->belongsToMany(Category::class, 'articles_has_categories', 'article_id', 'category_id');
    }

Articles_Has_Categories

• id
• article_id
• category_id

public function article ()
    {
        return $this->belongsTo(Article::class,'article_id');
    }

    public function category ()
    {
        return $this->belongsTo(Category::class,'category_id');
    }

Category

• id
• name

public function article(){
        return $this->belongsToMany(Article::class, 'articles_has_categories', 'category_id', 'article_id');
    }

Answer

Please try this:

    $article = Article::with(['category' => function($query) use ($category) {
            $query->where('category_id', $category);
        }
    ])->get();
