Как встроить этот запрос в laravel eloquent

У меня есть этот запрос

select est.*, bf.followup as bf_follow, bf.unidad as bf_unidad, bu.unidad as bu_unidad, bu.asistencia as bu_asistencia, bu.calificacion as bu_calificacion
from estudiantes as est
inner join bluecard as bc on bc.estudiante = est.usuario_id
inner join beneficiarios as bene on bene.usuario_creado = est.usuario_id
inner join (
select bluecard, followup, unidad
from bluecard_followups
order by bf_id desc
) bf on (bf.bluecard = bc.bc_id)
left join (
select bluecard, unidad, asistencia, calificacion
from bluecard_unidades
order by bu_id desc
) bu on (bu.bluecard = bc.bc_id)

where bc.status = 1
group by est.usuario_id
limit 500

Я знаю, как создавать соединения с помощью eloquent, но я не знаю, как их написать.

С кем-нибудь подобное случалось?
Кому-нибудь нужен такой запрос с laravel?

Помоги мне!
Спасибо

я запускаю запрос так:

$estudiantes = Estudiantes::select(
DB::raw("select est.*, bene.contrato as nro_contrato, bf.followup as bf_follow, bf.unidad as bf_unidad, bu.unidad as bu_unidad, bu.asistencia as bu_asistencia, bu.calificacion as bu_calificacion
from estudiantes as est
inner join bluecard as bc on bc.estudiante = est.usuario_id
inner join beneficiarios as bene on bene.usuario_creado = est.usuario_id
inner join (
select bluecard, followup, unidad
from bluecard_followups
order by bf_id desc
) bf on (bf.bluecard = bc.bc_id)
left join (
select bluecard, unidad, asistencia, calificacion
from bluecard_unidades
order by bu_id desc
) bu on (bu.bluecard = bc.bc_id)

where bc.status = 1
group by est.usuario_id
limit 500"))
->get();

и я получил эту ошибку:
