Customizing the Unique validation rule

How would I appropriately customize the Unique validation rule/method that Filament has according to the following? Here is my categories table:

Schema::create('categories', function (Blueprint $table) {
    $table->id();
    $table->foreignId('company_id')->constrained()->cascadeOnDelete();
    $table->string('name')->index();
    $table->string('type');
    $table->string('color');
    $table->boolean('enabled')->default(true);
    $table->foreignId('created_by')->nullable()->constrained('users')->nullOnDelete();
    $table->foreignId('updated_by')->nullable()->constrained('users')->nullOnDelete();
    $table->timestamps();

    $table->unique(['company_id', 'name', 'type']);
});

Schema::create('categories', function (Blueprint $table) {
    $table->id();
    $table->foreignId('company_id')->constrained()->cascadeOnDelete();
    $table->string('name')->index();
    $table->string('type');
    $table->string('color');
    $table->boolean('enabled')->default(true);
    $table->foreignId('created_by')->nullable()->constrained('users')->nullOnDelete();
    $table->foreignId('updated_by')->nullable()->constrained('users')->nullOnDelete();
    $table->timestamps();

    $table->unique(['company_id', 'name', 'type']);
});

This is what I have so far for the Field:

Forms\Components\TextInput::make('name')
  \\ ...
  ->unique(modifyRuleUsing: static function (Unique $rule, Request $request) {
      return $rule->where('company_id', auth()->user()->currentCompany->id)
                  ->where('type', $request->input('type'));
}),

Forms\Components\TextInput::make('name')
  \\ ...
  ->unique(modifyRuleUsing: static function (Unique $rule, Request $request) {
      return $rule->where('company_id', auth()->user()->currentCompany->id)
                  ->where('type', $request->input('type'));
}),

Will the above work? Or do I need to do something like this or something else?

Forms\Components\TextInput::make('name')
  \\ ...
  ->unique(modifyRuleUsing: static function (Unique $rule, Forms\Get $get) {
      return $rule->where('company_id', auth()->user()->currentCompany->id)
                  ->where('type', $get('type'));
}),

Forms\Components\TextInput::make('name')
  \\ ...
  ->unique(modifyRuleUsing: static function (Unique $rule, Forms\Get $get) {
      return $rule->where('company_id', auth()->user()->currentCompany->id)
                  ->where('type', $get('type'));
}),

You can't use $request in livewire requests. Second approach is the way to go

Oh I thought you could based on the documentation here: https://filamentphp.com/docs/3.x/forms/advanced#injecting-dependencies-from-laravels-container But okay thank you.

Yes, you can inject $request, but it's only going to work on page load (for example in the mount() method of a page), not for Livewire method calls. Livewire doesn't use HTTP requests, you're not doing a POST or a GET or whatever.

And since it’s ajax based the request isn’t actually the url in the browser.
