CRUD - Overview - php

Question

I succeeded the step "create" barring the overview.
My recordings are saved on PhpMyAdmin but not on my page index.blade.php I don't understand why ? I made several refreshments even so.
Here is my file AdminController.php
class AdminController extends Controller
{
public function index(){
/*$devis = Devis::all()->sortByDesc("created_at");
return view('admin.home', compact('devis'));*/
$students = Student::first()->paginate(5);
return view('student.index', compact('students'))
->with('i', (request()->input('page',1)-1)*5);
}
public function create()
{
return view('student.create');
}
public function store(Request $request)
{
$request->validate([
'firstname' => 'required',
'lastname' => 'required'
]);
Student::create($request->all());
return redirect()->route('student.index')
->with('success', 'save');
}
}
In my folder VIEWS with another folder which is Student which has 2 files:
Index.blade.php
#extends('student.template.master')
#section('left_menu')
#include('student.template.left_menu', array('current' => 'home'))
#endsection
#section('content')
<div class="px-content">
<div class="page-header">
<div class="row">
<div class="col-md-4 text-xs-center text-md-left text-nowrap">
<h1><i class="px-nav-icon ion-android-apps"></i>List </h1>
</div>
<hr class="page-wide-block visible-xs visible-sm">
<!-- Spacer -->
<div class="m-b-2 visible-xs visible-sm clearfix"></div>
</div>
</div>
<div class="row">
<div class="panel">
<div class="panel-body">
<div class="table-responsive">
<table class="table">
<a class="btn btn-sm btn-success" href="{{ route('student.create') }}">Create</a>
<thead>
<tr>
<th>Firstname</th>
<th>Lastname</th>
</tr>
</thead>
#foreach($students as $item)
<tr>
<td> {{$item->firstname}}</td>
<td> {{$item->lastname}} </td>
<td> <span class="left ion-close"></span></td>
</tr>
#endforeach
</table>
</div>
</div>
</div>
</div>
</div>
#endsection
And create.blade.php
#extends('student.template.master')
#section('left_menu')
#include('student.template.left_menu', array('current' => 'home'))
#endsection
#section('content')
<div class="px-content">
<div class="page-header">
<div class="row">
<div class="col-md-4 text-xs-center text-md-left text-nowrap">
<h1><i class="px-nav-icon ion-android-apps"></i>Devis</h1>
</div>
<hr class="page-wide-block visible-xs visible-sm">
<!-- Spacer -->
<div class="m-b-2 visible-xs visible-sm clearfix"></div>
</div>
</div>
<div class="row">
<div class="panel">
<div class="panel-body">
<div class="table-responsive">
<form class="panel-body" action="{{route('student.store')}}" method="POST">
#csrf
<fieldset class="form-group">
<label for="form-group-input-1">Firstname</label>
<input type="text" name="firstname" class="form-control" id="form-group-input-1">
</fieldset>
<fieldset class="form-group">
<label for="form-group-input-1">Lastname</label>
<input type="text" name="lastname" class="form-control" id="form-group-input-1" >
</fieldset>
Back
<button type="submit" class="btn btn-sm btn-primary">Submit</button>
</form>
</div>
</div>
</div>
</div>
</div>
#endsection
Do you have an idea please ? I am really stuck.

Answer 1

first() returns an instance of the class Student, you can't paginate on it. change
public function index(){
/*$devis = Devis::all()->sortByDesc("created_at");
return view('admin.home', compact('devis'));*/
$students = Student::first()->paginate(5);
return view('student.index', compact('students'))
->with('i', (request()->input('page',1)-1)*5);
}
to
public function index(){
/*$devis = Devis::all()->sortByDesc("created_at");
return view('admin.home', compact('devis'));*/
$students = Student::paginate(5);
return view('student.index', compact('students'))
->with('i', (request()->input('page',1)-1)*5);
}

Answer 2

In Laravel, when you use paginate(), it also comes with links() function. So all you needed to do was to pass the variable in the controller, as below:
public function index(){
$students = Student::get()->paginate(5);
return view('student.index', compact('students'));
}
Now, in index.blade.php, just reference the links() function:
{{ $students->links() }}
