Laravel 6 – Missing required parameters for [Route: suppliers.destroy] [URI: suppliers/{supplier}]

i have index page with a button to remove a column from a table.

@foreach ($suppliers as $supplier)
        <tr>
              <th>{{ $supplier -> idSupplier }}</th>
              <th style="color:blue;"><a href="/suppliers/{{$supplier->idSupplier}}">{{ $supplier -> column1 }}</a></th>
              <th>{{ $supplier -> column2 }}</th>
              <th>{{ $supplier -> column3  }}</th>
              <th>{!! $supplier -> column4 !!}</th>
              <th>
                  <a class="btn btn-warning" href="/suppliers/{{$supplier->idSupplier}}/edit" role="button">
                        <i class="fa fa-tools"></i>
                  Edit</a>
                  <a class="btn btn-danger" href="{{ action('SuppliersController@destroy') }}" role="button">
                        <i class="fa fa-eraser"></i>
                  Delete</a>
              </th>
        </tr>
@endforeach

but now everytime i open my index page it gives me this error message

FacadeIgnitionExceptionsViewException Missing required parameters for [Route: suppliers.destroy] [URI: suppliers/{supplier}]. (View: C:xampphtdocsInventresourcesviewssuppliersindex.blade.php)

this is my route

Route::resource('suppliers', 'SuppliersController');

and this is destroy function from SuppliersController

public function destroy($idSupplier)
    {
        $supplier = Supplier::find($idSupplier);
        $supplier->delete();
        return redirect('/suppliers')->with('success', 'Supplier removed');
    }

I already try this solution and it gives me another error message.

Answer

well you are not passing the required parameter for the controller’s action. destroy method receives a parameter idSupplier to perform its actions. from blade you are just calling the controller action without passing the parameter. make it like below:

<a class="btn btn-danger" href="{{ action('SuppliersController@destroy', ['idSupplier' => $supplier->idSupplier]) }}" role="button">
    <i class="fa fa-eraser"></i>
    Delete
</a>

but it won’t work. your registered route method is DELETE but it will redirect to a GET method. So use the follwing method for deleting.

<form action="{{ route('suppliers.destroy', $supplier->idSupplier) }}" method="POST">
    @csrf
    @method('DELETE')
    <button class="btn btn-danger btn-sm" title="Delete">Delete</button>
</form>
