Eloquent first() and loops - php

Question

I'm new to Eloquent and I'm having trouble when using it with loops.
Imagine I have a table in my db called ‘Jobs’ with:
Id – 1; value: engineer
Id – 2 ; value: doctor
Id – 3 ; value: nurse
I'd also have a JobTranslations table with each job translations. Then, I have this piece of code:
$jobTranslations = [];
$lang = $request->input('lang') ?? 'pt';
foreach(Job::all() as $job) {
$job = $job->with(['jobtranslations' => function($query) use ($lang) {
$query->where('languageCode', $lang);
}])->firstOrFail();
$jobTranslations[] = $job;
}
return ['translatedJobs' => $jobTranslations];
When I run this code, I’m expecting to get an array (jobTranslations) with those 3 jobs in it and each job’s translation.
However, I get instead an array with three items, but they’re all the same:
array([‘id’ => 1, ‘value’ => ‘engineer’, ‘jobtranslations’ => [another array]],
[‘id’ => 1, ‘value’ => ‘engineer’, ‘jobtranslations’ => [another array]],
[‘id’ => 1, ‘value’ => ‘engineer’, ‘jobtranslations’ => [another array]]
);
I’ve realized this is happening due to ‘firstOrFail’ but I don’t understand why. $job->firstOrFail() doesn’t make sense to me because it’s only one job (the current one in the loop) but I don’t want to use get() either.
In C#, using EF, I’d do something like this (no need to call get or first):
foreach(var job in jobs) {
translatedJobs.Add(job.Include(j => j.jobtranslations.FirstOrDefault(jt => jt.languageCode == lang)));
}
return translatedJobs;
Thanks in advance!

I assum what you ar looking for ist this:
$lang = $request->input('lang', 'pt');
$jobTranslations = Job::with([
'jobtranslations' => function ($query) use($lang)
{
$query->where('languageCode', $lang);
}
])->get()->toArray();
return ['translatedJobs' => $jobTranslations];
There is no need to do a Foreach Loop if you setup your Model correct.
