Efficient way to handle date between Controller and view in laravel - php

Question

I have an app that reads through a table of data and based on the name of the person, does a for each loop, producing a card for each job that is assigned to that user.
EG.
user1 Job 1
user1 Job 2
user2 Job 3
user3 Job 4
... could be 3000 plus records here with up to 40/50 users
The controller collects the data from the table and sends it in bulk to the view for a foreach user statment to produce the code for each user then for each Job where it matches the user.
Controller code:
function dash()
{
if($user = Auth::user())
{
$users= User::all();
$jobs= Job::all();
return view('jobview', compact('users','jobs'));
}
if(Auth::guest())
{
return redirect('/home');
}
}
The view code is simple:
#foreach($users as $user)
#foreach($jobs as $job)
#if ($job->technician == $user->id)
<!--The code in this include generates a few lines of code to create the card-->
#include('layouts/sublayouts.jobscard')
#endif
#endforeach
#endforeach
The core problem is, there can be over 3000 cards (all need to be visable at the same time) and there can be 40 users to show.
I assume the slowness is the for each loop being done in the view?
Any guidance would be appriciated.
Thanks

Answer 1

Try something like, this will do the comparasion when getting the data from the database instead, should be alot faster:
$user_id = Auth::user() -> id;
$jobs = Job::Where('technician', '=', $user_id)->get();
return view('jobview', compact('jobs'));
EDIT:
In response to comment for all Jobs, do an inverse One-to-many relationship, for example:
//Job Model
class Job extends Model
{
public function technician()
{
return $this->belongTo('App\User');
}
}
//Controller
$jobs= App\Job::All();
return('jobview', compact('jobs')
//View
#foreach($jobs as $job)
{{ $job -> technician -> [Insert Some User property you want here] }}
{{ $job -> jobName }}
And if you want to "group" them by user simply do orderBy('technician') in your controller.
