How to throw an error when importing ?

[xoco70]

Hi,

Depending on the user's role, layout is different, and there should have a different number of fields.

So, I want to be able to throw exception if the number of fields is not 6 for instance when importing users

How should I do that ?

I'm trying to do it like this, but I cannot make it work

/**
     * @param array $row
     *
     * @return \App\Models\User
     */
    public function model(array $row)
    {
            if (auth()->user()->isSuperAdmin()) {
                if (count($row) != 6) {
                throw new ValidationException(new \Illuminate\Validation\ValidationException(null, null), ["Le nombre de champ n'est pas 6"]);
            }
    }

public function model(array $row)
    {
            if (auth()->user()->isSuperAdmin()) {
                if (count($row) != 6) {
                   return null;
               }
    }

In your controller:

try {
    $import->import("your file");
} catch(\Illuminate\Validation\ValidationException $ex) {
    Log::debug("Le nombre de champ n'est pas 6", ["context" => self::class]);
}

problem is if I return null in model(), function is not throwing a ValidationException, it will succeed creating no user. That is the problem.
