How to count all the products that belongs to category(slug) Laravel 8 - laravel

Question

I am a beginner in Laravel. I need a little help.
I have an index.blade.php file which displays all the category names. When I click on on it will generate the slug link where I have all the products that in the category. So I would like to count only those products that is belongs to category's slug and display the number on the index.blade.php. Thanks for the help.
Route::get('view-category/{slug}', [ProductsController::class,'viewcategory']);
productsController:
public function viewcategory($slug){
if(Category::where('slug', $slug)->exists()){
$category = Category::where('slug', $slug)->first();
$products = Products::where('cateId', $category->id)->where('status','1')->get();
return view('admin.products.display', compact('category','products'));
}
else{
return redirect('/dashboard')->with('status',"Slug does not exist");
}
}
category Model:
class Category extends Model
{
use HasFactory;
protected $table = "categories";
protected $fullable = [
'name',
'slug',
'description',
'status',
'popular',
];
public function products(){
return $this->belongsTo(Products::class, 'id', 'cateId');
}
}
index.blade.php:
<thead>
<tr>
<th></th>
<th>Product Name</th>
<th>Category</th>
<th>Sub Category</th>
<th>Variations</th>
<th>Status</th>
<th>Action</th>
</tr>
</thead>
<tbody>
#foreach($category as $item)
<tr>
<td class="control" tabindex="0"></td>
<td>{{$item->products->productName}}</td>
<td>{{$item->name}}</td>
<td>{{$item->subCategory}}</td>
<td>{{$item->counter}}</td>
<td></td>
<td></td>
</tr>
#endforeach
</tbody>
</table>

Answer 1

You can still call relationships inside your blade files, so if you have a products relationship setup correctly, you only need to change your index blade to this
<td>{{$item->products()->count()</td>
If you have categories that don't have any products put this in your blade to check before showing the count (Its an if else statement just inline)
<td>{{$item->products ? $item->products()->count() : 'N/A'}}</td>

Answer 2

in your blade file add this line before your foreach
#if( $category->posts->count() )
//your #foreach code here
#endif
