Laravel Lucid whereHas by latest column in pivot table - php

Question

I have 3 tables : Orders ( id, name, surname, created_at and updated_at ), OrdersStatuses (order_id, order_status_name_id, created_at) and OrderStautsNames ( id and name ):
I have orders model which has method like this:
protected $appends = ['actual_status'];
public function orderProducts()
{
return $this->hasMany(OrderProduct::class);
}
public function statuses()
{
return $this->belongsToMany(OrderStatusName::class, 'order_statuses')
->withPivot('created_at');
}
public function getActualStatusAttribute()
{
return $this->statuses()->latest('set_at')->first();
}
I have problem with seraching all orders, where highest status id ( this info is in pivot table OrderStatuses, and I need name of this status which is in OrderStatusNames ) is like $statuses (this is an array with statuses ). I started do like this:
$orders = Order::query();
$orders->whereHas('statuses', function($query) use ($statuses) {
$query->whereIn('order_status_name_id', $statuses);
});
But it return me orders with not latest status, but this query search me throught all statuses... . Can i do this by latest status? I tryed to use current_status but I don't know how to get there.

Answer 1

Add this relation to your Order Model
public function lastStatus()
{
return $this->hasOne(OrderStatusName::class)->select('OrderStautsNames.*', 'order_statuses.order_id', DB::raw('MAX(order_statuses.set_at) as lastOrder'))->join('order_statuses', 'order_statuses.order_status_name_id', '=', 'OrderStautsNames.id')
}
Then eager load it
$orders = Order::whereHas('lastStatus', function ($query) use ($statuses) {
$query->whereIn('OrderStautsNames.id', $statuses);
})->get();
