Laravel get All with Relationships and Paginate relationship data - php

Question

I am trying to get all users and their associated (1:n) journals. However I want to add pagination to the associated journals, not the users
My Controller:
public function index()
{
$users = User::with(['journal'])->orderBy('name', 'asc')->get();
return view('journals/journals', ['users' => $users]);
}
My Blade:
#foreach($users as $user)
<a class="list-group-item list-group-item-action" data-toggle="collapse" href="#collapse{{$user->id}}" role="button" aria-expanded="false" aria-controls="collapse{{$user->id}}">
{{$user->name}}
</a>
<div class="collapse mt-1" id="collapse{{$user->id}}">
<div class="card card-body">
<div class="list-group">
<table class="table table-sm table-hover">
<thead>
<tr>
<th scope="col">Kunde</th>
<th scope="col">Betreff</th>
<th scope="col">Leistungsart</th>
<th scope="col">Beginn</th>
<th scope="col">Ende</th>
<th scope="col">Dauer</th>
<th scope="col">Arbeitszeit</th>
</tr>
</thead>
<tbody>
#foreach($user->journal as $journal)
<tr onclick="window.location='{{route('journal.show', [$journal->id])}}'">
<th scope="row">{{$journal->customer->name}}</th>
<td>{{$journal->title}}</td>
<td>{{$journal->type}}</td>
<td>{{$journal->started}}</td>
<td>{{$journal->ended}}</td>
<td>{{$journal->duration}}</td>
<td>{{$journal->worked}}</td>
</tr>
#endforeach
</tbody>
</table>
</div>
</div>
</div>
#endforeach
My Journal Model:
public function user(){
return $this->belongsTo('App\User', 'user_id', 'id');
}
My User Model:
public function journal(){
return $this->hasMany('App\Journal', 'user_id', 'id');
}
Again, what I am trying to achieve is that I can print out every user and paginate their journals, not paginate the users
I really hope someone can help me there

Answer 1

Render in blade
Above your journals for-each loop in your blade, try and put something like this:
#php
$paginated_journals = $user->journal()->paginate(10);
#endphp
And then, your for-each loop should look like this:
#foreach($paginated_journals as $journal)
...
#endforeach
After the for-each loop you can just put:
$paginated_journals->links()
to get the links for pagination
Pre-load data in controller
You can do the same thing server-side. Create a custom array that is empty, go through each user, and add sub array to that custom array:
array_push($custom_array, ['user' => $user, 'journals' => $user->journal()->paginate(10)])
This way you can send the custom array to your blade, loop through it, and render user data and paginated journals.
