Multiple level hasManyThrough relationship with Eloquent - php

Question

I'm using Eloquent in my PHP application and struggling with a hasManyThrough relationship.
Here's my structure :
Company
id
name
Admin
id
company_id
name
Offer
id
admin_id
name
Application
id
offer_id
candidat_id
Each Admin is part of a Company and can post Offer's, and the candidats can make an Application on that offer.
I'm trying to fetch all the applications that have been made on offers that have been started by admins of that company.
I've tried using the hasManyThrough relationship in my Company model, like so :
public function applications()
{
return $this->hasManyThrough("Application", "Offer");
}
but I get the following error :
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'offers.entreprise_id' in 'field list' (SQL: select `applications`.*, `offers`.`entreprise_id` from `applications` inner join `offers` on `offers`.`id` = `applications`.`offer_id` where `offers`.`entreprise_id` in (1))
Which makes sense, since it's thinking that the Offer is listed to the Company and not to the Admin.
How can I set it up so that it will look for the Admin's of that company, without having to fetch all the admins of the company and then looping through them, getting all the applications for each admins?
This would work, but it seems like a tedious way of doing it when Eloquent provides these relationships that make our lives easier. Is there a more elegant way of achieving what I want?

Answer 1

There is no native relationship for this case.
I created a HasManyThrough relationship with unlimited levels: Repository on GitHub
After the installation, you can use it like this:
class Company extends Model {
use \Staudenmeir\EloquentHasManyDeep\HasRelationships;
public function applications() {
return $this->hasManyDeep(Application::class, [Admin::class, Offer::class]);
}
}
