Prewarn about possible validation issues

Like when a field is required but not yet matched up to a column

In my project I added validation for each row & it has been super valuable Appending the errors to an error column allows very easy debugging In my project, outputs an invalid.csv which makes it easy to re-import only error rows after fixing

public function checkValidation($row)
{
    $rules = $this->importClass->getRules();

    $validator = Validator::make($row, $rules);

    $is_invalid = $validator->fails();

    if ($is_invalid) {
        $row['errors'] = implode(' ', $validator->messages()->all());

        $this->invalid[] = $row;
    }

    return $is_invalid;
}

I also had a duplicate check that does the same but duplicates.csv

public function checkDuplicates($row)
{
    if (!isset($this->importClass->duplicate) || 0 == count($this->importClass->duplicate)) {
        return false;
    }

    $conditions = collect($row)->intersectByKeys(array_flip($this->importClass->duplicate))->toArray();

    $models = app($this->importClass->model)
        ->withoutGlobalScopes()
        ->withoutTrashed()
        ->where($conditions)
        ->get();

    $is_duplicate = 0 != $models->count();

    if ($is_duplicate) {
        $resource = strtolower(str_plural(class_basename($this->importClass->model)));

        $row['links'] = $models->map(function ($model) use ($resource) {
            return url("admin/resources/$resource/$model->id");
        })->implode(', ');

        $this->duplicate[] = $row;
    }

    return $is_duplicate;
}
