I wrote a relation belongsToMany between products and photos and now I want to show products in the home page. I did it like so:

@foreach ($latestProducts as $product)
  <img src="{{$product->photos()->path}}">
@endforeach

homeController:

public function index()
    {
        $latestProducts = Product::orderBy('created_at' , 'desc')->limit(10)->get();
        return view('front.layouts.index' , compact('latestProducts'));
    }

photo model:

public function products() {
        return $this->belongsToMany(Product::class);
    }

product model:

public function photos() {
        return $this->belongsToMany(Photo::class);
    }

I got Undefined property: Illuminate\Database\Eloquent\Relations\BelongsToMany::$path .And when I write {{$product->photos[0]->path}} , the error changes to "Undefined array key 0. Also when I write {{$product->photos->path}} ,I get an error as "Property [path] does not exist on this collection instance."

I believe you got a photo attribute/field in the Photo model. Because photos is a collection of photos, you might want to write:

@foreach ($latestProducts as $product)
    @foreach ($product->photos as $photo)
        <img src="{{$photo->path}}">
    @endforeach
@endforeach

And only the first photo:

@foreach ($latestProducts as $product)
    <img src="{{$product->photos->first()->path}}">
@endforeach

// Or to be safe
@foreach ($latestProducts as $product)
    <img src="{{optional($product->photos->first())->path}}">
@endforeach

// Or this in php 8
@foreach ($latestProducts as $product)
    <img src="{{$product->photos->first()?->path}}">
@endforeach

You have to use

{{ $product->photos->path }}

cause when you deal with relations in blade you deal with it as a property of class of the father class unlike when you deal with it in eloquent ORM you can use photos()

Basically the error is saying that there is no property photos in the $products. Assuming that the table name is correct and the foreign keys too

you can just do:

public function index()
{
    $latestProducts = Product::with('photos')->orderBy('created_at' , 'desc')->limit(10)->get();
    return view('front.layouts.index' , compact('latestProducts'));
}

And in blade file try to remove the (), because it will load the relationship.

@foreach ($latestProducts->photos as $product)
  <img src="{{$product->path}}">
@endforeach
