Livewire throwing error when using paginated data - laravel

So I am being given this error when trying to paginate my data and send it in to a view through a livewire component.
I am trying to get all posts and display at max 5 posts per page using pagination in laravel.
Livewire version: 2.3.1
Laravel version: 8.13.0
Error:
Livewire\Exceptions\PublicPropertyTypeNotAllowedException
Livewire component's [user-posts] public property [posts] must be of type: [numeric, string, array, null,
or boolean]. Only protected or private properties can be set as other types because JavaScript doesn't
need to access them.
My Component:
<?php
namespace App\Http\Livewire;
use Livewire\Component;
use App\Models\Post;
use Livewire\WithPagination;
class UserPosts extends Component
{
use WithPagination;
public $posts;
public $type;
protected $listeners = ['refreshPosts'];
public function delete($postId)
{
$post = Post::find($postId);
$post->delete();
$this->posts = $this->posts->except($postId);
}
public function render()
{
if($this->type == 'all')
$this->posts = Post::latest()->paginate(5);
else if($this->type == 'user')
$this->posts = Post::where('user_id',Auth::id())->latest()->paginate(5);
return view('livewire.user-posts', ['posts' => $this->posts]);
}
}
My Blade:
<div wire:poll.5s>
#foreach($posts as $post)
<div style="margin-top: 10px">
<div class="post">
<div class="flex justify-between my-2">
<div class="flex">
<h1>{{ $post->title }}</h1>
<p class="mx-3 py-1 text-xs text-gray-500 font-semibold"
style="margin: 17px 0 16px 40px">{{ $post->created_at->diffForHumans() }}</p>
</div>
#if(Auth::id() == $post->user_id)
<i class="fas fa-times text-red-200 hover:text-red-600 cursor-pointer"
wire:click="delete({{$post->id}})"></i>
#endif
</div>
<img src="{{ asset('image/banner.jpg') }}" style="height:200px;"/>
<p class="text-gray-800">{{ $post->text }}</p>
#livewire('user-comments', [
'post_id' => $post->id,
'type' => 'all'
],
key($post->id)
)
</div>
</div>
#endforeach
{{ $posts->links() }}
</div>

$posts should not be declared as a property in the Livewire component class, you passed the posts with the laravel view() helpers as data.
Remove the line
public $posts;
And replace $this->posts by $posts in the render function:
public function render()
{
if($this->type == 'all')
$posts = Post::latest()->paginate(5);
else if($this->type == 'user')
$posts = Post::where('user_id',Auth::id())->latest()->paginate(5);
return view('livewire.user-posts', ['posts' => $posts]);
}
}

Laravel Livewire Message only to a specific user

I took over a working chat application. to send a message, the original code uses a user list, which then checks whether a message exists.
In this case, it will redirect to the chat blade. If not, a new message will be created and then redirected to Chat blade.
Github to the app
https://github.com/thee-king-yodah/laravel-livewire-chat-message-application
I would like to change this and use a button on a profile page, but I'm currently working on the implementation and get stuck.
If I add the livewire into my blade it list a button for all users.

$createdConversation->save();

Laravel 8 form select option dropdown problem

Am having problem here
I have two tables
Department table
with fields
id dept_code dept_name
I also have Persons table
with fields
id Persons_names Dept_name Position_held
I have a data entry form to enter data to the Persons_table
the problem am having is I want to create select option to get Dept_name From Department_table but am always getting undefined value error.
this is my form
{!! Form::open(['url' => 'persons_form/store']) !!}
{{ csrf_field() }}
<div class="form-row">
<div class="form-group col-md-6">
{{Form::label('FullNames', 'Fullnames')}}
{{Form::text('names', '',['class'=>'form-control','placeholder'=>'Persons Fullnames'])}}
</div>
<div class="form-group col-md-6">
{{Form::label('Department', 'Department')}}
#foreach ($depts as $dept)
{{
Form::select('department', $dept->department_name, null, ['class'=>'form-control','placeholder' => 'Select Department'])
}}
#endforeach
</div>
<div class="form-group col-md-12">
{{Form::label('Position', 'Position')}}
{{Form::text('level', '',['class'=>'form-control','placeholder'=>'Departmental Position'])}}
</div>
</div>
<div>
{{Form::submit('Save Data',['class'=>'btn btn-outline-primary text-center',])}}
</div>
{!! Form::close() !!}
this is my personsController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use App\Models\People;
class PeopleController extends Controller
{
public function index()
{
$depts = DB::table('departments')->select('department_name')->get();
return view('strategic_plan.people_form', ['depts' => $depts]);
}
public function create()
{
$depts = DB::table('departments')->pluck('department_name');
}
public function store(Request $request)
{
$this->validate($request,[
'names'=>'required',
'department'=>'required',
'level' =>'required'
]);
$persons =new People;
$persons->names=$request->input('names');
$persons->department=$request->input('persons');
$persons->level=$request->input('level');
$dept->save();
return redirect('/people')->with('message','Person Added Succesifully');
}
public function show()
{
$persons = People::all()->sortByDesc("id");
return view('strategic_plan.people',compact('persons'));
}
public function edit($id)
{
}
public function update(Request $request, $id)
{
//
}
public function destroy($id)
{
//
}
}
When I try to open the Form am getting
$depts is undefined
Try using compact, And get #dd in your blade of $depts and share the code.
Use
return view('strategic_plan.people_form', ['depts' => $depts]);
instead of
return view('strategic_plan.people_form', compact('depts');

Get objects of related tables from a collection laravel

I want to pass the result of a searching action but I am facing a problem because it is returning an array and from that all the relationships of the table are not working
result view. For this I can only access the data on my table not the related data through relationships
#extends('layouts.app')
#section('content')
#foreach ($result as $object)
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">
<h3>Details for the animal</h3>
</div>
<div class="card-body">
<div class="col-12">
<p><strong>Id: </strong>{{ $object->id }}</p>
</div>
</div>
</div>
</div>
</div>
</div>
#endforeach
#endsection
Here is my controller
<?php
namespace App\Http\Controllers;
use App\Animal;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class SearchController extends Controller
{
public function index()
{
Animal::all();
return view('search.index');
}
public function postSearch(Request $request)
{
$serial_number = $request->input('search');
$this->getResult($serial_number);
return redirect()->route('result',$serial_number);
}
public function getResult($serial_number){
$result = DB::table('slaughters')->where(function ($query) use ($serial_number) {
$query->where('id','LIKE',"%$serial_number%");
})->latest()->get();
return view('search.result', ['result'=>$result]);
}
}
And my routes
Route::get('/search','SearchController#index')->name('search');
Route::post('/get','SearchController#postSearch');
Route::get('/search/{result}','SearchController#getResult')->name('result');
I would like to access data from the table related to this one too. What am to do
Slaughter model
class Slaughter extends Model
{
protected $guarded = [];
public function user(){
return $this->belongsTo(User::class);
}
public function animal(){
return $this->belongsTo(Animal::class);
}
You must create model Slaughter and define relations.
And then you can get result:
public function getResult($serial_number)
{
$result = Slaughter::with(['name_of_relation_1', 'name_of_relation_2'])->latest()->get();
return view('search.result', ['result'=>$result]);
}
In your Controller:
use App\Slaughter;
public function getResult($serial_number) {
$result = Slaughter::where('id', 'like', "%{$serial_number}%")
->with('user', 'animal')
->latest()
->get();
return view('search.result', compact('result'));
}
In your view you can then access the relationships like so:
{{ $object->user }}
{{ $object->animal }}

How to Call/Display Foreach Loop after Login

I had problem on calling page inside Foreach Loop.Although It is Okay before I click Login, but when I'd try to login,only the html tag where loaded and foreach loop cannot... On my HomeController extends Controller
public function index()
{
return view('pages.welcome');
}
on where I call welcome page. and inside of it which is foreach loop.
<div class="row">
<div class="col-md-8">
#foreach ($posts as $post)
<div class="post">
<h3>{{ $post->title }}</h3>
<p>{{ substr($post->body, 0,300) }}
{{ strlen($post->body) > 300 ? "..." : " " }}</p>
Read More...
</div>
<hr>
#endforeach
</div>
</div>
And I think the problem is my route:
Route::get('/home', 'HomeController#index');
You haven't passed the $posts variable to the view.
Change
public function index()
{
return view('pages.welcome');
}
To something like this:
public function index()
{
$posts = \App\Post::all(); //Assuming your model is called "Post" in the App namespace
return view('pages.welcome', compact('posts'));
}
NOTE: compact('posts') is just a shortcut for ['posts'=>$posts]

Individual profile pages and searches Laravel 5.2

Having a real confusing time with this project, my issue is I'm trying to get my search working but for some reason its not pulling results from my query when there is that information in the database, also when I click on the username in the top corner of my page, it should redirect to the user page but instead I get this error "NotFoundHttpException in Application.php line 879:" with the URl looking like this "http://localhost/WorldLink/users/firstName%20=%3E%20Auth::user%28%29-%3EfirstName" and I have exhausted all other means of trying to fix it so I'm back for some help! my code is below Im using laravel 5.2:
Users.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Users extends Model
{
protected $table = 'users';
protected $fillable = [
'id', 'firstName', 'lastName', 'bio', 'homeLocation', 'currentLocation', 'email', 'password',
];
public function getName()
{
if ($this->firstName && $this->lastName) {
return "{$this->firstName} {$this->lastName}";
}
if ($this->firstName) {
return $this->firstName;
}
return null;
}
public function getNameOrLocation()
{
return $this->getName() ?: $this->currentLocation;
}
public function getFirstNameOrLocation()
{
return $this->firstName ?: $this->currentLocation;
}
public function getAllAvatarsUrl()
{
return "https://www.gravatar.com/avatar/{{ md5($this->email) }}?d=mm&s=40";
}
}
SearchController.php:
<?php
namespace App\Http\Controllers;
use DB;
use App\Users;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Http\Request;
class SearchController extends BaseController
{
public function getResults(Request $request)
{
$query = $request->input('query');
if (!$query) {
return back();
}
$users = Users::where(DB::raw("CONCAT(firstName, ' ', lastName)"), '
LIKE', "%{$query}%")
->orWhere('currentLocation', 'LIKE', "%{$query}%")
->get();
return view('search/results')->with('users', $users);
}
ProfileController.php
<?php
namespace App\Http\Controllers;
use App\User;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Http\Request;
class ProfileController extends BaseController
{
public function getProfile($firstName)
{
$users = User::where('firstName', $firstName)->first();
if (!$users) {
abort(404);
}
return view('profile.index')
->with('users', $users);
}
}
userblock.blade.php
<div class="media">
<a class="pull-left" href="{{ route('profile/index', ['firstName' => $users->firstName]) }}">
<img class="media-object" alt="{{ $users-getNameOrLocation() }}" src="{{ $users->getAllAvatarsUrl() }}">
</a>
<div class="media-body">
<h4 class="media-heading">{{ $users->getNameOrLocation() }}</h4>
</div>
#if ($users->currentLocation)
<p>{{ $users->currentLocation }}</p>
#endif
results.blade.php
#extends('layouts.app')
#section('content')
<h3>Search Results for "{{ Request::input('query') }}"</h3>
#if (!$users->count())
<p>No Results Found</p>
#else
<div class="row">
<div class="col-lg-12">
#foreach ($users as $user)
#include('users/partials/userblock')
#endforeach
</div>
</div>
#endif
#endsection
And finally my two routes, the problem is connected in here somewhere I just cant find where its going wrong.
Route::get('/search', [
'uses' => '\App\Http\Controllers\SearchController#getResults',
'as' => 'search/results',
]);
Route::get('/users/{firstName}', [
'uses' => '\App\Http\Controllers\ProfileController#getProfile',
'as' => 'profile/index',
]);
The Link:
#if (Auth::guest())
<li>Login</li>
<li>Register</li>
#else
<ul class="nav navbar-nav">
<form class="navbar-form navbar-left" role="search" action="{{ route('search/results') }}">
<input type="text" class="form-control" placeholder="Search" name="query">
</form>
<li>{{ Auth::user()->firstName }}</li>
<li>Timeline</li>
<li>Link</li>
<li>Journeys <span class="journey-num">{{ Auth::user()->journeys }}</span></li>
<li>Forum</li>
</ul>
Defo quoting incorrectly
....
<li>{{ Auth::user()->firstName }}</li>
....
Note closing ' moved to after firstName array key.
That should at least fix the link
