@jmacdiarmid You don’t use form requests with Livewire components; Livewire handles the lifecycle itself so any validation should be in the component itself as per the error message.

Using Custom Form Request with Livewire v2
I created a form request since I need to customize the field validation messages and passing it to my store method. When opening my modal create form and attempt to submit an empty form, I can see that it's picking up the custom error messages for each field. However, when I try to submit a form with valid data I get the following exception error. How do I use Form Requests with Livewire?
Livewire\Exceptions\MissingRulesException
Missing [$rules/rules()] property/method on Livewire component: [admin.campaign-packages].
Here is my form request:
public function authorize()
{
return true;
}
public function rules(): array
{
return [
'title' => 'required|string',
'duration_id' => 'required|numeric|min:0|not_in:0',
'monthly_impressions' => 'required',
'monthly_investment' => 'required',
'price' => 'required',
];
}
public function messages(): array
{
return [
'duration_id.required' => 'The Commitment Length field is required',
];
}

Ok. I got it working. Thank you. It took me a little bit to wrap my head around what I was reading in the Livewire docs. It looks like my issue was more related to the $validationAttributes array than the custom messages. I also had to remove related variables from the validatedOnly() in the updated method as well the validate() call in the store method.

@okiaso Hi dear I like ur solution very much but how the new StoreRoleRequest() looks like from inside?

<?php
namespace App\Http\Livewire\Role\System;
use App\Http\Requests\StoreRoleRequest;
use Livewire\Component;
class Edit extends Component
{
public $item; // role
public $name; // form inpute: name
public function render()
{
return view('livewire.role.system.edit');
}
public function mount()
{
// Processing the form with RoleController::update, not Livewire
$this->name = $this->item->name;
}
// Reuse external "Form Request Validation"
protected function rules()
{
$request = new StoreRoleRequest();
return $request->rules();
}
protected function updated()
{
$this->validate();
}
}

I've been liking [for certain cases] Taylors pattern in jetstream... he puts the validation in the Action. https://github.com/laravel/jetstream/blob/2.x/stubs/app/Actions/Fortify/UpdateUserProfileInformation.php
Then uses the action in the livewire controller only resets the error bag there... https://github.com/laravel/jetstream/blob/2.x/src/Http/Livewire/UpdateProfileInformationForm.php
