Laravel 8 call other model relationship in model relationship

i have that relationship, and the mainproblem is how do i show Product where have relationship with product_image / discounts and render that on blade?

There my Cart class model :

 public function products()
{
    return $this->belongsTo(Product::class, 'product_id','id');
}

There’s my product class model :

  public function discounts()
{
    return $this->hasMany(Discount::class, 'product_id', 'id');
}

public function images()
{
    return $this->hasMany(ProductImage::class, 'product_id', 'id');
}

public function getProductImage()
{
    return $this->images->image_name;
}

This is both whatdiscount and product_images code to returning relationship

 public function products()
{
    return $this->belongsTo(Product::class, 'product_id','id');
}

and how do i show that on my Cart blade? i’ve use this but still error

@foreach($cart as $data)
                                            @foreach ($data->products as $item)
                                            <th scope="row">
                                                <img src="{{ asset('images/'.$item->image->image ) }}"class="border" style="width:120px;" alt="">
                                            </th>
                                            @endforeach
@endforeach
