Custom Validation with relation

->rules([function ($record) {
    return function (string $attribute, $value, Closure $fail) use ($record) {
      if (Model::where('agreement_id', $replaceWithRelationID)->whereDate('start_date', '>=', $value)->exists()) {
        $fail("There is already a price agreement right/after this date");
      }
    };
}]),
->rules([function ($record) {
    return function (string $attribute, $value, Closure $fail) use ($record) {
      if (Model::where('agreement_id', $replaceWithRelationID)->whereDate('start_date', '>=', $value)->exists()) {
        $fail("There is already a price agreement right/after this date");
      }
    };
}]),
I need to replace replaceWithRelationID with the parameter ID from the url or the relationship its on.

if your slug is like mypage/{relationID} and you have a public $relationIDin your Page, you could access it like $this->relationID.

or you use it in a querystring -> info on that can be found here: https://laravel-livewire.com/docs/2.x/rendering-components

Oh - okay. So just to get you right: url looks like this /admin/company-agreements/{WHATEVER}/edit and you wanna access the "WHATEVER"?

yea basically, unless there is another way Maybe you can access the relation where the price will be saved on or something
