php - Laravel BelongsToMany Get Category Name in Index List

I'm new to Laravel and to php.

I created my categories for my news system.

On my page where I list all my news, I have the following problem while showing the category to which the news is linked.

I'm bringing the category of my article with ID 5.

But I can't do that for other news.

How can I do this on my page where I list all my news?

Thank you to everyone in advance.

My Controller Page

   public function index()
    {

        $data = News::all()->sortByDesc('created_at');
        $parentcategory= News::find(5)->parent_category()->limit(1)->get();

        
        return view ('SS.haber.index',compact('data','parentcategory'));
    }
Copy code

My Model Page

    public function parent_category()

    {
        return $this->belongsToMany('App\Models\SS\NewsCategory', 'news_category_s');

    }


Copy code

My Views

<td> @foreach ($parentcategory as $pc) {{$pc->category_name}} @endforeach </td>
Copy code

I think the problem I'm having in this area is very simple.

I was only able to pull the category of news number 5 id.

I don't know how to print categories of other data.

If public function update ($ id) {

it would work the way I did.

But I should be able to pull the categories of all records on the index page.
