Laravel: one-to-many retrieving single record in view - php

Question

I'm currently learning Laravel 5.6. So my problem is this, I have the following Model:
class Tour extends Model
{
//
protected $fillable = [
'name',
'price',
'category',
'overview',
'activity',
'exclusion',
'inclusion',
'policies',
'guide_id',
'province_id'
];
public function tourImages(){
return $this -> hasMany('App\TourImage');
}
}
class TourImage extends Model
{
//
protected $fillable = [
'name',
'path',
'tour_id'
];
public function tour(){
return $this -> belongsTo('App\Tour');
}
}
So 1 Tour can have multiple TourImages. What i want to do is that i want to print out all the tours on the index page. But i only want to take one TourImage file to display for each tour. I return only array of all tours from controller. Is there a way that i can retrieve image directly on the blade view without returning more variable from the controller?
Here's what I write for my index method:
public function index($province_id = null)
{
$tours = Tour::where('province_id', $province_id)->get();
return view('tours.index', ['tours' => $tours]);
}
Here's my index view:
#extends('layouts.app')
#section('content')
<div class="col-md-8 offset-md-2">
<br/>
<table class="table">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">Name</th>
<th scope="col">Picture</th>
<th scope="col">Price</th>
</tr>
</thead>
<tbody>
#foreach($tours as $tour)
<tr>
<th scope="row">{{ $tour->id }}</th>
<td>{{ $tour->name }}</td>
<td><img src="/storage/{{ $tour->tourImages->path }}" width="200px"/></td>
<td>{{ $tour->price }}</td>
</tr>
#endforeach
</tbody>
</table>
</div>
#endsection

Answer 1

you can pass one image of each tour by this code :
$tours=Tour::with(['tourImages'=>function($query){
$query->first();
}])->get();
and in view:
#foreach($tours as $tour)
#if ($tour->tourImages->count())
<img src="/storage/{{ $tour->tourImages[0]->path }}" width="200px"/>
#endif
#endforeach

Answer 2

you need to use with() to get records.like this.
$tours = Tour::with('tourImages')->where('province_id', $province_id)->get();

Answer 3

You can add new relation in your Tour model like
public function latestTourImage() {
return $this->hasOne('App\TourImage')->latest();
}
Then you can fetch it using this in your controller file
$tours = Tour::with('latestTourImage')->where('province_id', $province_id)->get();
and then you can print it in your blade file like
$tour->latestTourImage->path
