Property [costo] does not exist on this collection instance - laravel

Question

i need to print the price of a service, but can't find the column with the price.
maybe I'm doing something wrong with relationships, but I can't figure it out on my own
database:
Controller:
public function details(Request $request,$id){
$datax = [
'category_name' => 'apps',
'page_name' => 'calendar',
'has_scrollspy' => 0,
'scrollspy_offset' => '',
];
$evento = Eventos::find($id);
$servicio = \App\Models\Eventos::select("servicio_id")->where('servicio_id', $evento->id)->get('servicio_id');
$event = Eventos::find($id);
$event->asistencia = $request->asistencia;
$event->cancelado = $request->cancelado;
$event->save();
return view("evento",[
"event" => $event,
"servicio" => $servicio
])->with($datax);
}
blade.php
<div class="input-group mb-4">
<div class="input-group-prepend">
<span class="input-group-text">$</span>
</div>
<input type="text" value="{{$servicio->costo}}" class="form-control col-md-3" aria-label="Amount (to the nearest dollar)">
<div class="input-group-append">
<span class="input-group-text"></span>
</div>
</div>
I need to print the "costo" column in relation to service_id
help please

Answer 1

you can use laravel elequent relationship one to one.
if you have this two Servicio.php & Evento.php in App/Models or whatever your models name is, only replace your models in below code do this:
1-
in App/Models/Servicio.php define this relationship:
public function evento()
{
return $this->hasOne(Evento::class);
}
in App/Models/Evento.php define this relationship:
public function servicio()
{
return $this->belongsTo(Servicio::class);
}
now in controller add this:
$evento = Eventos::where('id' , $id)->with('servicio')->first();
in blade use this:
<input type="text" value="{{$evento->servicio->costo}}" >
2- also you can do this but i suggest you the first one:
only in your Codes change this:
$servicio = \App\Models\Servicio::where('id', $evento->servicio_id)->first();
