Laravel 以一对多关系更新/编辑图像

我有两个具有一对多关系的模型事件和事件图像，我可以上载链接到一个事件的多个图像，但问题是当我试图通过更新链接到该事件的所有图像进行编辑时，只上载一个图像，而不是所有其他图像，所以我的问题是，我如何一次或单独更新与该事件相关的所有图像？请帮忙，我们将不胜感激

事件迁移

   public function up()
  {
   Schema::create('events', function (Blueprint $table) {
    $table->id();
    $table->string('title');
    $table->string('date');
    $table->string('time');
    $table->string('venue');
    $table->mediumText('body');
    $table->timestamps();
   });
  }

       public function up()
   {
      Schema::create('event_images', function (Blueprint $table) {
       $table->id();   
       $table->string('images');
       $table->string('caption');
       $table->integer('event_id')->unsigned();
       $table->foreign('event_id')->references('id')->on('events')
       ->onDelete('cascade');
       $table->timestamps();
    });
  }

EventImage迁移

   public function up()
  {
   Schema::create('events', function (Blueprint $table) {
    $table->id();
    $table->string('title');
    $table->string('date');
    $table->string('time');
    $table->string('venue');
    $table->mediumText('body');
    $table->timestamps();
   });
  }

       public function up()
   {
      Schema::create('event_images', function (Blueprint $table) {
       $table->id();   
       $table->string('images');
       $table->string('caption');
       $table->integer('event_id')->unsigned();
       $table->foreign('event_id')->references('id')->on('events')
       ->onDelete('cascade');
       $table->timestamps();
    });
  }

这是EventController

public function store(Request $request)
{


    //Handle File Upload
 if ($request->hasFile('images')) {

    $files = $request->file('images');
    // Get filename with extention 

    foreach($files as $file) {
    $filenamewithExt = $file->getClientOriginalName();
    // Get just filename
    $filename = pathinfo($filenamewithExt, PATHINFO_FILENAME);
    // Get just Extention
    $extension = $file->getClientOriginalExtension();
    // Filename to store
    $filenameToStore = $filename.'_'.time().'.'.$extension;
    // Upload Image
    $path = $file->storeAs('public/images', $filenameToStore);
    }
} else {
    $filenameToStore = 'noimage.jpg';
}



// Create EventImages
 $event = Event::create($request->all());

   foreach($request->images as $image) {

      $images = $image->store('images');
      $filenamewithExt = $image->getClientOriginalName();
// Get just filename
      $filename = pathinfo($filenamewithExt, PATHINFO_FILENAME);
// Get just Extention
      $extension = $image->getClientOriginalExtension();
// Filename to store
      $filenameToStore = $filename.'_'.time().'.'.$extension;
   EventImage::create([
    'event_id' => $event->id,
    'images'   => $filenameToStore,
    'caption'  => $request->caption,
    
  ]);
 }


public function update(Request $request, $id)
  {
            //Handle File Upload
 if ($request->hasFile('images')) {

    $files = $request->file('images');
    // Get filename with extention 

    foreach($files as $file) {
    $filenamewithExt = $file->getClientOriginalName();
    // Get just filename
    $filename = pathinfo($filenamewithExt, PATHINFO_FILENAME);
    // Get just Extention
    $extension = $file->getClientOriginalExtension();
    // Filename to store
    $filenameToStore = $filename.'_'.time().'.'.$extension;
    // Upload Image
    $path = $file->storeAs('public/images', $filenameToStore);
    }
} else {
    $filenameToStore = 'noimage.jpg';
}



// UPDATE EventImages
  $event = Event::find($id);
  $event->update($request->all());
  foreach($request->images as $image) {

$images = $image->store('images');
$filenamewithExt = $image->getClientOriginalName();
// Get just filename
$filename = pathinfo($filenamewithExt, PATHINFO_FILENAME);
// Get just Extention
$extension = $image->getClientOriginalExtension();
// Filename to store
$filenameToStore = $filename.'_'.time().'.'.$extension;



$event->images()->update([
    'event_id' => $event->id,
    'images'   => $filenameToStore,
    'caption'  => $request->caption,
    
    ]);
   }
}
