How to paginate a “has many” relationship that is ordered?

Question

I would like to paginate the following relationship (a Category having many Apps):

class Category extends Model
{

To get this to work, I had to bypass the Eloquent Relationships. I created a repository instead.

In this example, a user has lots of reports.

App\Repositories\ReportsRepository

This will get the reports records for a user.

namespace App\Repositories;

use App\User;

class ReportsRepository
{
    public function findByUser(User $user, $paginate = 10)
    {
        $reports = User::find($user->id)
            ->reports()
            ->orderBy('created_at', 'DESC')
            ->paginate($paginate);
        return $reports;
    }
}

ReportController

Here we call the ReportsRepositroy to get the records (I've removed the Auth code).

class ReportController extends Controller
{
    public function index(\App\Repositories\ReportsRepository $repo)
    {
        $reports = $repo->findByUser(Auth::user());
        return view('report.index', ['reports' => $reports]);
    }
}

View - report/index.blade.php

The important bit for pagination here is {!! $reports->render() !!}. This generates the links of the pagination.

@extends('layout.master')

@section('content')
    

        
Reports

        @if ($reports->count())
            
                @foreach($reports as $report)
                    
                @endforeach
                

                

                    

                        
Status
                        
Info
                        
Date
                    
                

                

                        
{{ $report['status'] }}
                        
{{ $report['info'] }}
                        
{{ $report['created_at'] }}
                    
            
        @else
            
No records exist.
        @endif

        {!! $reports->render() !!}

    
@stop

This is all that's needed. Laravel deals with the rest of the pagination magic itself.

Hope this helps.
