Validation Fails on Second Unique Value Test on Update

Hello!

I've got a problem with Validation. I've googled for an answer, but the only option I saw (doesn't relate directly to my issue) requires me to create my own Validation rule, which seems like overkill?

I have a table with two columns which need to be Unique.

When creating the record, the validation works fine.

When I try to Update, the 'Abbreviation' field shows as duplicate.

public function update(Request $request, Film $film)
{
    //
    $this->validate($request, [
        'name' => 'required|min:3|unique:"films", "name", ' . $film->id ,
        'abbreviation' => 'required|max:5|unique:"films", "abbreviation", ' . $film->id,
        'type_id' => 'required|numeric|filled',
    ]);

    $film = new Film;

    $film->name = $request->name;
    $film->abbreviation = $request->abbreviation;
    $film->type_id = $request->type_id;

    $film->save();

    return redirect()->route( 'films.index' )->with('message', 'Successfully updated Film.');
}

What's happening? What am I doing wrong?

Thank you!
