Laravel在数组上忽略id？ （多次更新）

Question

In Laravel, we can do validation on array like

$this->validate($request, [
    'users.*.name' => 'bail|nullable|min:2',
    'users.*.username'=>'bail|nullable|min:4|unique:t0101_user,username,' .$xx
    'users.*.password' => 'bail|nullable|min:6'
], $this->messages());

In this scenario, what should i passed to the xx ? I will need something like

users.*.id

Thank you, (Laravel version 5.4)

Laravel Unique Validation Rule

Documentation Link

You need to manually create a validator using the unique rule

use Illuminate\Validation\Rule;

    Validator::make( $data, [
        'users.*.username' => [
            'bail', 'nullable', 'min:4', Rule::unique( 't0101_user', 'username' )->ignore( 'users.*.id' )
        ]
    ]);
