How can i get query result id in controller from Laravel? - php

Question

I want to take houses lists and houses pictures on mysql from laravel. But, i have this problem. Using the process below:
$houses = Houses::query()
->orderBy('sort', 'ASC')
->take('6')
->get();
This query, give houses list to me. And I need to use the houses I retrieve to get their photos, this is the best I could think of:
$pictures = Housephotos::query()
->where('house_id', '=', $houses->house_id)
->get();
Question one: This process is correct?
Question two : How can do this?

Answer 1

Add a relation to Houses:
class Houses extends Model
{
public function photos()
{
return $this->hasMany(Housephotos::class);
}
}
and now you can get the photos easily like:
$houses = Houses::query()
->orderBy('sort', 'ASC')
->take('6')
->get();
foreach ($houses->photos as $photo) {
echo $photo->id;
}
the problem with that is, select query will run n times (5 times for this example).
if you add with to the query however, then laravel will run a single in query to get the pictures:
$houses = Houses::query()
->with('pictures')
->orderBy('sort', 'ASC')
->take('6')
->get();

Answer 2

You need to make a relationship between Housephotos and House so that there is house_id in Housephotos. If this is true, you can already use the houses Id you have to retrieve the houses Id:
Say you already have the houses, then you can have:
$pictures = Housephotos::whereIn('house_id', '=', $houses->pluck('id')->toArray())
->get();
This will give you the houses photos.
