Hi, as per subject how to retrieve data form field that has relation.

My Relation

class iklan extends Model
{
public function foto()
 {
    return $this->hasOne('App\foto');
 }
}

table "foto" fields :

$table->increments('id');
            $table->integer('iklan_id')->unsigned();
            $table->foreign('iklan_id')->references('id')
                                       ->on('iklan')
                                       ->onUpdate('cascade')
                                       ->onDelete('cascade');

            $table->string('foto_1')->default('/images/foto/nofoto.png');
            $table->string('foto_2')->nullable();
            $table->string('foto_3')->nullable();
            $table->string('foto_4')->nullable();
            $table->string('foto_5')->nullable();
            $table->string('foto_6')->nullable();
            $table->string('foto_7')->nullable();
            $table->string('foto_8')->nullable();

in Controller :

public function listings()
    {
        $iklans = iklan::latest()->where('active',1)
                                 ->with('kategori','subkategori','provinsi','kota','foto')
                                 ->paginate(5);



        return view('iklan.listings',compact('iklans'));
    }

in View :

	@foreach($iklans as $iklan)

            
           
            <div class="row  listing-row">
                 <div class="col-sm-2">
                    <a href="{{ route('iklan_link' , [$iklan->id, $iklan->slug])}}" class="thumbnail ">**This <img alt="176 * 120"  src="{{ $iklan->foto->foto_1 }}"> as bold**</a>

                </div>
                    
                <div class="col-sm-10">
                    <h3><a class="" href="{{ route('iklan_link' , [$iklan->id, $iklan->slug])}}">{{$iklan->judul}} - <strong>{{$iklan->harga}}</strong></a></h3>
                    <p class="muted">Kategori  <strong>{{ $iklan->kategori->nama }}</strong></p>
                    <p class="muted">Posted {{ $iklan->created_at->diffForHumans() }} to <a href="listings.html#" class="underline">{{$iklan->subkategori->nama}}</a></p>
 </div>
</div>

dd($iklan)
