Eloquent select field with relationship - eloquent

Question

Here is the controller
$query = ( new Product() )->where( 'quantity', '>', 0 )
->where( 'product_category_id', '!=', null )
->where( 'soft_delete', 0 )
->whereBetween( 'price', [ $priceFrom, $priceTo ] )
->with( [
'campaign' => function ( $q ) {
$q->where( 'stock', '>', 0 );
$q->where( 'expire', '>', Carbon::today()->toDateString() );
}] )->first()// Check the campaign table if it has any record or not
->orderBy( 'price', $sort );
Now I am try to get the price from the campaign so what I trying to do in blade is this
#if(count($product->campaign))
<del>$425.00</del>
{!! $product->campaign->price !!}
#endif
but I got
Property [price] does not exist on this collection instance.
how can I select the price from the campaign?

Answer 1

$query = Product::where('quantity', '>', 0)
->whereIsNotNull('product_category_id')
->where('soft_delete', 0)
->whereBetween('price', [$priceFrom, $priceTo])
->with([
'campaign' => function ( $q ) {
$q->where( 'stock', '>', 0 );
$q->where( 'expire', '>', Carbon::today()->toDateString());
}
])
->first()// Check the campaign table if it has any record or not
->orderBy('price', $sort);
Property [price] does not exist on this collection instance. This error because your Product model have HasMany campaign relation.
For get separate campaign price use
#if(count($product->campaign))
<del>$425.00</del>
#foreach ($product->campaign as $compaign)
{!! $coampaign->price !!}
#endforeach
#endif
