Undefined property: Illuminate\Pagination\LengthAwarePaginator::$event_parts - php

I received this error while trying to run two-layer loops in order to get a list out of an array:
Undefined property: Illuminate\Pagination\LengthAwarePaginator::$event_parts
I wanted to produce a table where it lists all my events and at the same time there is a column that listed all the attending participants.
Here is the phpmyadmin table:

Your $post->category is not an object which is why this error is coming.
Try
dd($post->category)
and you'll see what's in it. That will help you to debug the real problem.
First eager load the relation (to prevent N+1 issues) using:
public function index()
{
$posts = Post::with('category')->get();
return view('posts.index')->with('posts', $posts);
}
Then if you still get the error, it might be due to the fact that the post you are trying to view does not have category, so the relation is null. So when you try to get the category id, it throws that exception that null does not have id.
You can simply solve it by checking if there is any category before:
#if($post->category)
<a href="{{ route('categories.edit', $post->category->id ) }}">
{{ $post->category->name }}
</a>
#endif
Use eager loading in your controller before injecting the model to the view.
$post->load('category');
Make sure that each post has a relation with a category.

Laravel 7. How to fetch records from various tables using foreign key in laravel?

Laravel 7 and 2 tables: comp, computers.
I would like to display in the view index.blade.php the name of the computer e.g. DELL, IBM, LENOWO instead of id of this name.
What the foreach syntax should look like to retrieve the computer name from the computers table.
And when you add a new PC, what should the dropdownlist look like?

On Comp model, make a belongsTo relation :
public function computer()
{
return $this->belongsTo('App\Computer', 'name_id');
}
Now you can access this relation, from your blade, as:
#foreach($comp as $comp)
<tr>
<td>{{ $comp->computer->name }}</td>
</tr>

Update() function in the Laravel Resource Controller is not working

My create.blade.php is exactly the same as my edit.blade.php, the only changes are in the Form::open() line. And the edit page even displays my old data on the input fields but when I make a change & click Update, it just doesn't update anything in the database or the index page - so what am I doing wrong? Thanks in advance and please feel free to ask if any more code is required for you guys to crack this one.
Try this one out:
public function update(Request $request, Student $student)
{
$input = $request->all();
$student->fill($input)->save();
return redirect()->route('main.index')->with('update','Student has been updated!');
}
Try..
public function update(Request $request,$id)
{
$student = Student::find($id);
$student->name = $request->input('name');
$student->gender = $request->input('gender');
$student->address = $request->input('address');
$student->class = $request->input('class');
$student->save();
return redirect()->route('main.index')->with('update','Student has been updated!');
}
request()->all() contains method and token information. Can you maybe pass it through a validator?
$validated = request()->validate([
'name' => 'required',
'address' => '',
..
]);
$student->update($validated);
In your edit.blade.php,
{!! Form::submit('route_to_update()',['type'=>'submit','class'=>'btn btn-danger btn-block']) !!}
change "Edit"
And you can check your route by in your console like "php artisan route:list"
and check your route is reached
by var_damp() or var_export() or dd()in your student controller update function

Get the name of authenticated user and store it

I have a form in which you submit a "project". One of the field is "created by", but the user does not update this, it gets the name of the authenticated user in that moment and inserts it into the db.
I know how to retrieve the user's name, but the problem is that when I login with another user, then all the name change, because I store the name each time.
This is my project controller
<?php
namespace App\Http\Controllers;
use App\Project;
use App\Client;
use Auth;
use Illuminate\Http\Request;
class ProjectController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function __construct()
{
$this->middleware('auth');
}
public function index()
{
return view('projects.index', [
'project' => Project::all()
]);
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
if (Auth::user()->role != 1){
return redirect()->back();
}else{
return view('projects.create',[
'project' => new Project,
'client' => new Client
]);
}
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $r)
{
$validatedData = $r->validate([
'proj_title' => 'required|max:100',
'client_id' => 'required',
'proj_desc' => 'required',
]);
$currentUser = Auth::user()->name;
$r['created_by'] = $currentUser;
$project = Project::create($r->all());
return redirect('/projects')->with('store','');
}
/**
* Display the specified resource.
*
* #param \App\Project $project
* #return \Illuminate\Http\Response
*/
public function show(Project $project)
{
//
}
/**
* Show the form for editing the specified resource.
*
* #param \App\Project $project
* #return \Illuminate\Http\Response
*/
public function edit(Project $project)
{
return view('projects.edit', compact('project'));
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param \App\Project $project
* #return \Illuminate\Http\Response
*/
public function update(Request $r, Project $project)
{
$project->update($r->all());
return redirect('/projects')->with('update','');
}
/**
* Remove the specified resource from storage.
*
* #param \App\Project $project
* #return \Illuminate\Http\Response
*/
public function destroy(Project $project)
{
$project->delete();
return redirect('/projects')->with('delete','');
}
}
And this is my index
#section('content')
<div class="row">
<div class="col">
#if (Auth::user()->role == 1)
<a class="btn btn-success" href="/projects/create">Add Project</a>
#endif
</div>
<div class="col"></div>
<div class="col">
#if(session()->has('store'))
<div class="alert alert-success mt-2" role="alert">
<strong>Project created</strong>
</div>
#elseif(session()->has('update'))
<div class="alert alert-success mt-2" role="alert">
<strong>Project updated</strong>
</div>
#elseif(session()->has('delete'))
<div class="alert alert-success mt-2" role="alert">
<strong>Project deleted</strong>
</div>
#endif
</div>
</div>
<br>
<table class="table table-bordered table-hover">

#if (Auth::user()->role==1)

#endif

<tbody class="">
#foreach ($project as $project)

#if (Auth::user()->role==1)

<div class="dropdown">
<button class="btn btn-danger dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Action</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item" href="{{route('projects.edit',$project)}}">Edit</a>
<form method="POST" action="{{route('projects.destroy',$project)}}" onsubmit="return confirm('Are you sure you want to delete this?')">
#method('DELETE')
#csrf
<button class="dropdown-item" type="submit">Delete</button>
</form>
</div>
</div>
</td>
#endif
</tr>
#endforeach
</tbody>
</table>
#endsection
I think your problem is that you are using:
{{ $project->Auth::user()->name }}
instead of
{{ $project->created_by }}
