在 Laravel 中加载观察者时出现问题

Question

我试图让观察者知道，当我在表单中创建我的 property/ad 时，我会转储一些字符串和信息，但我只是收到成功消息，即 property/ad 是在没有转储的情况下创建的，并且信息。它还将其插入数据库中。我只是关注 Laravel 的常规文档。任何帮助表示赞赏。这是我的代码。

PropertyObserver.php

<?php
namespace App\Observers;

use App\Property;

class PropertyObserver
{
    public function created(Property $property)
    {
        dd('Propertyyyyyyyyyy!!!', $property);
    }

    public function updated(Property $property)
    {

    }

    public function deleted(Property $property)
    {

    }
}

AppServiceProvider.php

<?php
namespace App\Providers;

use App\Property;
use App\Observers\PropertyObserver;
use Illuminate\Support\Facades\Schema;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        $this->publishes([
            base_path().'/config/permissions.php' => config_path('permissions.php'),
        ]);
        $this->publishes([
            base_path().'/config/roles.php' => config_path('roles.php'),
        ]);
    }

    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Schema::defaultStringLength(191);
        $this->mergeConfigFrom(
            base_path().'/config/permissions.php', 'permissions'
        );
        $this->mergeConfigFrom(
            base_path().'/config/roles.php', 'roles'
        );

        Property::observe(PropertyObserver::class);
    }
}

PropertyController.php

public function store(StorePropertyInfo $request, Property $property, Video $video)
{
    $request->validated();

    $categories = DB::table('categories')
    ->whereIn(
        'category',
        [
            $request->propertyType,

                        'updated_at' =>  Carbon::now()
                    ]);

    $property->find($property_id)->category()->attach($categories);

    $image_arr = array_filter(explode(',', $request->image), 'strlen');

            Storage::move(
                "public/tmp/$value",
                "public/property/$property_id/gallery/$value"
            );
        }

        if (in_array($ext, $videoExtensions)) {

    return redirect()

Laravel 观察者只观察 Eloquent 事件，例如 Model::create();
所以事件没有被调度，因为你使用 DB facade 直接插入值而不是使用 Eloquent ORM
因此，将您的代码更改为使用 Eloquent 而不是

$property_id = $property->create([
                        'title' =>  $request->title,
                        'description' => $request->description,
                        'email' => $request->email,
                        'number' => $request->number,
                        'city' => $request->city,
                        'street' => $request->adresa,
                        'price' => $request->cena,
                        'quadrature' => $request->kvadratura,
                        'main_photo_id' => $main_photo_id,
                        'main_video_id' => $main_video_id,
                        'active' => 'Q',
                        'page_views' => '0',
                        'user_id' => Auth::user()->id,
                        'expires_on' =>  Carbon::now()->addDays(30),
                        'created_at' =>  Carbon::now(),
                        'updated_at' =>  Carbon::now()
                    ])->id;

不要忘记在您的模型中使属性可填充
或者就在你的 App\Property

protected $guarded = []; // yolo
