How to show records filtered by specific category

Question

how can I list a musician of a certain category in my blade file with an if?

Answer 1

If you just want to list or show musicians of a particular category on the view then you can filter the musicians in the controller method and then send the filtered data to view

public function group()
{
    return view('pages.group', [
        'musicians' => Musician::where('category_id', 10)->get()
    ]);
}

And then in blade view

@foreach($musicians as $musician)
    <p>{{ $musician->musician_name }} {{ $musician->musician_surname }}</p>
@endforeach

it works thanks. but if I wanted to print on one line the musicians of the category with id 10 and on another line the musicians of the category with id 40? always on the same blade file

public function group()
{
    return view('musicians', [
        'categories' => Musician::get()->groupBy(function($item) {
            return $item->category_id;
        })
    ]);
}

@foreach($categories as $catetory)
    @foreach($category as $key => $musician)
        <p>{{ $musician->musician_name }} {{ $musician->musician_surname }}</p>
    @endforeach
@endforeach
