laravel-excel-export-import-example's Issues

Fails to skip data with errors

On failure doesn't skip errors but goes on to add it to the database.

Environment

maatwebsite/excel verrsion:3.1
PHP Version: 8.0

Below is the model

public function rules(): array
  {
      return [
    'cus_name' => 'bail|required|string|max:255',
    'cau_cat' => 'required|integer|between:1,4',
    'cus_cat' => 'required|integer|between:1,4',
    'cus_type' => 'required|integer|between:1,2',
    'cus_idnum' =>  'required|string|max:255',
    'cus_idtype' => 'required|integer|between:1,16',
    'cus_type' => 'required|integer|between:1,4',
    'listtype_id' =>'required|integer|between:1,4',
    'cus_dob' => 'required|date|date_format:Y-m-d',
      ];
  }
  public function chunkSize(): int
  {
      return 1000;
  }

  public static function afterImport(AfterImport $event)
  {
  }

  public function onFailure(Failure ...$failure)
  {
      Log::stack(['import-failure-logs'])->info(json_encode($failure));
  }

The code in the controller

 $file = $request->file('file')->store('import');

        $import = new CustomersImport;
       
      
          $import->import($file);
          foreach ($import->failures() as $failure) {
            $failure->row(); // row that went wrong
            $failure->attribute(); // either heading key (if using heading row concern) or column index
            $failure->errors(); // Actual error messages from Laravel validator
            $failure->values(); // The values of the row that has failed.
       }

        if ($import->failures()->isNotEmpty()) {
            return back()->withFailures($import->failures());
        }

Catch an error while importing huge CSV in queue using laravel excel

I am using ShouldQueue method to have the large CSV into Queue but the errors of validations I am not able to catch them!

public function registerEvents(): array { return [ ImportFailed::class => function(ImportFailed $event) { dd($event); // This I will write into the FILE or send EMAIL but the job runs successfully but validation errors keep empty. $this->importedBy->notify(new ImportHasFailedNotification); }, ]; }

My code looks like below...

public function registerEvents(): array { return [ ImportFailed::class => function(ImportFailed $event) { $filename = public_path('tmp').'/validation_error.txt'; $myfile = fopen($filename, "w"); fwrite($myfile, "domo"); fclose($myfile); }, ]; }

I am in hope that if there is any error validation_error.txt file will have "Demo" inside it.

I just wanted to add those errors in a file and email to the user that's it.

Also, I have crossed verify by removing ShouldQueue it gives me proper errors for email already exists a kind of.

Please help if you have any ideas! Thanks!
