Get the last record in a belongsToMany association - mysql

Question

I have a belongsToMany association between Appointment and Status models. The below query returns all of the statuses and I want to alter it to pull the last status assigned to the appointment.
$query = Appointment::query();
$query->with('statuses');
$query->with("agent");
$query->with("instruction_type");
$query->with("sign_up_customer");
$table = Datatables::of($query);
I have tried altering the query with this but it doesn't work.
$query->with('statuses')->latest();
This is my raw query:
select * from `users` where `users`.`id` = '1' limit 1
select count(*) as aggregate from (select '1' as `row_count` from `appointments`) count_row_table
select * from `appointments` limit 100 offset 0
select `statuses`.*, `appointment_status`.`appointment_id` as `pivot_appointment_id`, `appointment_status`.`status_id` as `pivot_status_id` from `statuses` inner join `appointment_status` on `statuses`.`id` = `appointment_status`.`status_id` where `appointment_status`.`appointment_id` in ('2') order by `created_at` desc
select * from `agents` where `agents`.`id` in ('1')
select * from `instruction_types` where `instruction_types`.`id` in ('1')
select * from `organisations` where `organisations`.`id` in ('1')
So this works, but it runs two queries on Statuses
$query = Appointment::with(['statuses' => function ($query) {
$query->latest()->first();
}]);
$query->with("agent");
$query->with("instruction_type");
$query->with("sign_up_customer");
$table = Datatables::of($query);

Answer 1

In order to get the latest record from the database, you should have a created_at column to reach that. In this case, you can do something like that:
Appointment::with(['statuses' => function ($query) {
$query->orderBy('created_at', 'desc')->first();
}])->get();

Answer 2

try
$query->with(["statuses"=>function($q){
$q->latest();
}])->get()
not tested but guess it should work
