How can I generate access error and error message, leaving user on the page? - laravel-livewire

Question

In laravel / jquery apps if I need to make checks if user is logged I make in controller:
$loggedUser = Auth::user();
if ( empty($loggedUser->id) ) {
return response()->json(['error_code'=> 1, 'message'=> "You must be logged!"],HTTP_RESPONSE_INTERNAL_SERVER_ERROR);
}
as I do not need to leave the user from the page, but only restrict some functionality
I show error message above using bootstrapGrowl library.
Now with laravel 7 /livewire 1.3 / turbolinks:5 / alpine#v2 I search how can I generate error and
show similar error message, leaving user on the page ?
UPDATED :
Let me explain it with detailed example :
In laravel / jquery apps I have in JS code :
var quiz_quality_radio= $('input[name=quiz_quality_radio]:checked').val()
var href = this_frontend_home_url + "/make-quiz-quality";
$.ajax( {
type: "POST",
dataType: "json",
url: href,
data: {"quiz_quality_id": quiz_quality_radio, "vote_id": this_vote_id, "_token": this_csrf_token},
success: function( response )
{
$('input[name=quiz_quality_radio]:checked').prop('checked', false);
frontendVote.showQuizQualityResults()
popupAlert("Thank you for rating ! Your rate was added!", 'success')
},
error: function( error )
{
$('input[name=quiz_quality_radio]:checked').prop('checked', false);
popupAlert(error.responseJSON.message, 'danger') // 'info', 'success'
}
});
and relative action in control :
public function make_quiz_quality(Request $request)
{
$requestData = $request->all();
$quiz_quality_id = ! empty($requestData['quiz_quality_id']) ? $requestData['quiz_quality_id'] : '';
$vote_id = ! empty($requestData['vote_id']) ? $requestData['vote_id'] : '';
if ( ! Auth::check()) {
return response()->json(['message' => "To rate you must login to the system !"], HTTP_RESPONSE_BAD_REQUEST);
}
if (empty($quiz_quality_id)) {
return response()->json([
'message' => "To rate you must select quiz quality !",
'quiz_quality_id' => $quiz_quality_id
], HTTP_RESPONSE_OK);
}
$vote = Vote::find($vote_id);
if ($vote === null) {
return response()->json([ 'message' => "Vote Item # " . $vote_id . " not found !"],HTTP_RESPONSE_NOT_FOUND);
}
$loggedUser = Auth::user();
$found_count = QuizQualityResult
::getByVoteIdAndUserId($vote_id, $loggedUser->id)
->count();
if ($found_count > 0) {
return response()->json(['message' => "You have already rated '" . $vote->name . "' # vote !", 'vote_id' => $vote_id],
HTTP_RESPONSE_BAD_REQUEST);
}
$newVoteItemUsersResult = new QuizQualityResult();
try {
$newVoteItemUsersResult->quiz_quality_id = $quiz_quality_id;
$newVoteItemUsersResult->vote_id = $vote_id;
$newVoteItemUsersResult->user_id = $loggedUser->id;
DB::beginTransaction();
$newVoteItemUsersResult->save();
DB::commit();
} catch (Exception $e) {
DB::rollBack();
return response()->json(['message' => $e->getMessage(), 'voteCategory' => null], HTTP_RESPONSE_INTERNAL_SERVER_ERROR);
}
return response()->json(['message' => '', 'id' => $newVoteItemUsersResult->id], HTTP_RESPONSE_OK_RESOURCE_CREATED);
} // public function make_quiz_quality(Request $request)
and in case of error generated in error block I show message with function popupAlert
(implemented with bootstrapGrowl), without leaving the page.
That is what I want to make in livewire / turbolinks / alpine app. How can I do it?
UPDATED # 2:
That is just listing of items user can vote for:
<div class="table-responsive">
<table class="table text-primary">
#foreach($quizQualityOptions as $key=>$next_quiz_quality_option)
<tr>
<td>
<input class="" type="radio" name="quiz_quality_radio" id="quiz_quality_radio_{{ $next_quiz_quality_option }}" value="{{ $key }}">
<label class="col-form-label" for="quiz_quality_radio_{{ $next_quiz_quality_option }}">{{ $next_quiz_quality_option }}</label>
</td>
</tr>
#endforeach
</table>
</div>
<div class="row p-3">
<a class="btn btn-primary a_link" onclick="javascript:frontendVote.MakeQuizQuality()">Rate !</a>
</div>
with 2 restrictions :
User must be logged
Any logged user can vote only once
these 2 errors were genarated at server.
UPDATED # 3:
I found decision with using of axios, like :
<button type="submit" class="btn btn-primary btn-sm m-2 ml-4 mr-4 action_link" #click.prevent="submitNewTodo()">
Submit
</button>
submitNewTodo() {
console.log('submitNewTodo::')
let is_insert= 1
let current_toto_id= 1
axios({
method: (is_insert ? 'post' : 'patch'),
url: '/api/todos' + (!is_insert ? "/" + current_toto_id : ''),
data: {
text : this.new_todo_text,
priority : this.new_todo_priority
},
}).then((response) => {
this.new_todo_text= ''
this.new_todo_priority= ''
this.loadTodosRows()
popupAlert( 'Todo ' + (is_insert ? 'added' : 'updated') + ' successfully !', 'success' )
}).catch((error) => {
var validationErrors= convertObjectToArray(error.response.data.errors.text)
this.validation_errors_text= ''
validationErrors.map((next_error, index) => {
if(next_error && typeof next_error[1] != "undefined" ) {
this.validation_errors_text += '<li>'+next_error[1]+'</li>'
}
})
popupErrorMessage(error.response.data.message)
});
},
With it I show message both on success and failure as I need but I see big disadvantage with it
as I use livewire and I would like to use livewire here, if that is possible...
Hope I explained what I want clearly...
Thanks!

With Alpine.js and axios you could do something like this, note that I'm not sure whether or not this_frontend_home_url, this_vote_id and this_csrf_token will be defined.
<div x-data="quiz()">
<div>
<div class="table-responsive">
<table class="table text-primary">
#foreach($quizQualityOptions as $key=>$next_quiz_quality_option)
<tr>
<td>
<input x-model="selected_quiz" class="" type="radio" name="quiz_quality_radio"
id="quiz_quality_radio_{{ $next_quiz_quality_option }}" value="{{ $key }}">
<label class="col-form-label"
for="quiz_quality_radio_{{ $next_quiz_quality_option }}">{{ $next_quiz_quality_option }}</label>
</td>
</tr>
#endforeach
</table>
</div>
<div class="row p-3">
<a class="btn btn-primary a_link" #click="submitQuizQuality()">Rate !</a>
</div>
</div>
</div>
<script>
function quiz() {
return {
selected_quiz: null,
submitQuizQuality() {
const url = this_frontend_home_url + "/make-quiz-quality";
axios.post(url, {
quiz_quality_id: this.selected_quiz,
vote_id: this_vote_id, // no idea where this is coming from,
_token: this_csrf_token // no idea where this is coming from
}).then(() => {
// reset "checked" state
this.selected_quiz = null;
frontendVote.showQuizQualityResults();
popupAlert("Thank you for rating ! Your rate was added!", 'success');
}).catch(error => {
// reset "checked" state
this.selected_quiz = null;
if (error && error.response) {
popupAlert(error.response.message, 'danger')
}
});
}
}
}
</script>
