How to search with select 2 in laravel and ajax? - ajax

Question

I'm trying to load into Select2 the selected value extracted from the DB. Id values are saved in a JSON field that contains the id values or the field '*' that I manage as 'All'.
I want to search first_name and last_name in users table.
AJAX
<script>
$(document).ready(function() {
$('#plaintiffId').select2({
ajax: {
url: '{{ route('admin::reports.plaintiffId') }}',
dataType: 'json',
delay: 250,
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
first_name: item.user.first_name,
last_name: item.user.last_name,
}
})
};
},
cache: true
}
});
</script>
web.php
Route::get('reports/plaintiffId', 'Admin\ReportController#plaintiffId')->name('reports.plaintiffId');
Controller
public function plaintiffId(Request $request, $term)
{
$data = [];
if($request->has('q')){
$search = $request->q;
$data = $search->when($term, function ($query) use ($term){
return $query->whereHas('plaintiff', function ($query) use ($term) {
$query->where('first_name', 'like', "%{$term}%");
$query->orWhere('last_name', 'like', "%{$term}%");
});
});
}
return response()->json($data);
}
Model
public function scopeSearch($query, $term)
{
return $query->when($term, function ($query) use ($term){
return $query->whereHas('plaintiff', function ($query) use ($term) {
$query->where('first_name', 'like', "%{$term}%");
$query->orWhere('last_name', 'like', "%{$term}%");
});
});
}
public function plaintiff()
{
return $this->belongsTo(User::class, 'plaintiffId');
}
I get this error in network

You have $term parameter in your controller but you dont send any parameter to your controller, you should send term parameter by ajax to your controller
