Laravel 8 unique validation rule doesn't work with user

I'm using Laravel 8 and the unique validation rule to ensure that a record remains unique, I'm now trying to extend this so that it's unique per user as well, but when expanding the functionality and using the rule in array form it doesn't seem to validate the user ID and instead gives me a integrity constraint violation.

So I have a table called brands, and this table contains two columns in question: brand and user_id, I need to ensure that when storing a record that the brand is unique against the brand column and that the logged in in user's ID the one making the request, e.g:

Two users can have the same brand, but a single user can't have multiples of the same brand.

$validator = Validator::make($request->all(), [
    'brand' => [
        'required',
        'string',
        Rule::unique('brands')->where(function ($query) {
            return $query->where('user_id', Auth::id());
        })
    ],
    'url' => 'required|string',
    'telephone' => 'required|string|min:11|max:11'
]);

I've also tried:

'brand' => 'required|string|unique:brands,brand,user_id,' . Auth::id()

What am I missing?

CodePudding user response：

According to the documentation you have to use the ignore() function:

Rule::unique('users')->ignore($user->id),

on your case:

Rule::unique('brands')->ignore($user->id, 'user_id'),
