Although its no good Practice Accessing the DB in Blade (better do this in the controller and pass the data) you can do:
<div class="price"><strong>Products</strong>
<span>
{{ BasicModel::where('sub_id', $row->sub_id)->count() }}
</span>
</div>
Its not tested, but have a look at the Eloquent docs, the count() method is explained there.
Update: I am not shure if laravel will find the class BasicModel (I never would access Models directly in blade, as stated do this in the controller and pass the data.) So maybe you need to write it with the full Namespace most likely {{ \App\BasicModel::where() }}.

Livewire Laravel - TypeError: Cannot read property 'getAttributeNames' of null

I'm fetching data from Ajax after sending a form. There is a listener that is setting the attribute to my component.
What I'm trying to achieve is to display my results after having submitted the form.
In the component, the model has been well retrieved but when I would like to display it to my component, I get an error.
directive_manager.js:26 Uncaught (in promise) TypeError: Cannot read property 'getAttributeNames' of null
at _default.value (directive_manager.js:26)

<div id="results-products" class="results-products">

var product= fetchData(url);
window.livewire.emit('set:product', product)
...
</script>
charts-products.blade.php
<div>
#isset($product)
#foreach ( $product->category as $category)
<div class="card">
<div class="card-header">
<h4>Product category</h4>
</div>
</div>
#endforeach
#endisset
</div>
ChartsProducts.php
<?php
namespace App\Http\Livewire;
use Livewire\Component;
use App\Models\Product;
class ChartsProducts extends Component
{
public $products;
protected $listeners = [
'set:product' => 'setProduct'
];
public function render()
{
return view('livewire.charts-products');
}
public function setProduct($product)
{
$this->product= Product::find($product);
//I have checked and the assigned variable is ok
}
}
The products is a model and has a relationship Category.
Is there something that I missed ?
This has to do with the way the dom-differ inside Livewire behaves. Try adding a key to the loop item
<div>
#isset($product)
#foreach ($product->category as $category)
<div class="card" wire:key="{{ $loop->index }}">
<div class="card-header">
<h4>Product category</h4>
</div>
</div>
#endforeach
#endisset
</div>
See the troubleshooting in the docs https://laravel-livewire.com/docs/troubleshooting
Also, change your public property from $products to $product

Laravel - Getting all records not just the first and putting together?

I have tried asking this question to everyone but nobody can see why I am trying to do it or why its not working but I will try my best to explain it properly this time.
I have a simple government page on my website that shows 3 panels in bootstrap with Higher Government, Senior Ministers and Junior Ministers. Inside each of them panels it shows a list of accounts assigned to that government rank.
Here is my government.blade.php:
#include('frontend.header')
<div class="col-md-12" style="padding-bottom:24px;">
<ul class="nav navtab nav-tabs" id="myTab" style="border-bottom:none;border-radius:1px;">
<li style="padding-right:13px;" class="active"><a style="" data-target="#higher_government_team" data-toggle="tab"><i class="fa fa-diamond" aria-hidden="true"></i> The Monarch/PM</a></li>
<li style="padding-right:13px;"><a style="" data-target="#senior_government_team" data-toggle="tab"><i class="fa fa-university"></i> Seniors</a></li>
<li style="padding-right:13px;"><a style="" data-target="#junior_government_team" data-toggle="tab"><i class="fa fa-university"></i> Juniors</a></li>
</ul>
</div>
<div class="col-md-8">
<div class="tab-content">
<div class="tab-pane active" id="higher_government_team">
<div class="panel panel-info">
<div class="panel panel-body">
higher gov here
</div>
</div>
</div>
<div class="tab-pane" id="senior_government_team">
<div class="panel panel-info">
<div class="panel panel-body">
senior gov here
</div>
</div>
</div>
<div class="tab-pane" id="junior_government_team">
<div class="panel panel-info">
<div class="panel panel-body">
#foreach ($juniorGovernment as $governmentMember)
{{ $governmentMember->user_id }}<br>
#endforeach
</div>
</div>
</div>
</div>
</div>
<div class="col-md-4">
</div>
</div>
#include('frontend.footer')
Here is my controller for displaying the page:
<?php
namespace App\Http\Controllers\Frontend\User;
use Auth;
use Cache;
use Illuminate\Http\Request;
use App\Database\Website\User\Roleplay;
use App\Database\Website\Roleplay\GovernmentRole;
use App\Database\Website\Roleplay\Life\LifeEvents;
class GovernmentController
{
public function getView()
{
$higherGovernment = Cache::remember('government.higher_government', 1, function() {
return GovernmentRole::where('government_type', 'higher_government')->first()->stats;
});
$seniorGovernment = Cache::remember('government.senior_government', 1, function() {
return GovernmentRole::where('government_type', 'senior_ministers')->first()->stats;
});
$juniorGovernment = Cache::remember('government.junior_government', 1, function() {
return GovernmentRole::where('government_type', 'junior_ministers')->first()->stats;
});
return view('frontend.community.government', compact('juniorGovernment', 'seniorGovernment', 'higherGovernment', 'royalty'));
}
}
Now as you can see, I only select the first record where government_type matches. But the issue is I have multiple government roles with that government type and I want to get all the account stats for all records with that government type. I have looked at others suggestions and none of them work, either throwing an error or don't do what I want to do.
Now, I have modals for each Roleplay and GovernmentRoles, I have posted them both below.
GovernmentRole:
namespace App\Database\Website\Roleplay;
use Eloquent;
class GovernmentRole extends Eloquent
{
protected $primaryKey = 'id';
protected $table = 'srp_government_roles';
public $timestamps = false;
protected $fillable = [];
public function stats(){
return $this->hasMany('App\Database\Website\User\Roleplay', 'government_id');
}
}
Roleplay:
use Eloquent;
class Roleplay extends Eloquent
{
protected $primaryKey = 'id';
protected $table = 'srp_user_statistics';
public $timestamps = false;
protected $fillable = [];
public function user()
{
return $this->belongsTo('App\Database\Website\User\Player', 'user_id', 'id');
}
public function government_role()
{
return $this->belongsTo('App\Database\Website\Roleplay\GovernmentRole', 'government_id');
}
}
So what I am trying to achieve is not just grabbing all the Roleplay instances for the FIRST government role record in the database it finds but putting together ALL roleplay instances for ALL records that match government_type either higher_government, senior_ministers, or junior_ministers.
If I understand what you are asking, can you not do something like fetching the stats on your loop through in blade? For example (I removed the cache, its adding complexity to the question/answer without any benefit):
// controller
$higherGovernment = GovernmentRole::where('government_type', 'higher_government')->get();
// blade
#foreach($higherGovernment as $g)
{{ $g->id }}
{{ $g->name }}
#foreach($g->stats as $stat)
{{ $stat->id }}
{{ $stat->something }}
#endforeach
#endforeach

Update multible rows in laravel 4

I wanted to update multiple rows in the database and have found a way to do it. but it does not seem like the best way to do it, since it is doing it in multiple calls at the moment.
I wanted to now if there is a better way to do this.
The homecontroller with the updatePersons function:
<?php
class HomeController extends BaseController {
public function index()
{
$persons = Person::get();
return View::make('hello')
->with(compact('persons'));
}
public function updatePersons()
{
$persons = Person::get();
foreach ($persons as $person) {
$person->fname = Input::get('fname'.$person->id);
$person->lname = Input::get('lname'.$person->id);
$person->save();
}
return Redirect::route('home')->with('succes', 'Siden er opdateret');
}
}
the view with the form
#extends('layouts.master')
#section('content')
<div class="container">
<ul class="list-group">
{{ Form::open(array('route'=>'personUpdate', 'method' => 'post')) }}
#foreach ($persons as $person)
<li class="list-group-item">
{{ Form::text('fname'.$person->id,$person->fname,array('class'=>'form-control', 'placeholder'=>'fname')) }}
{{ Form::text('lname'.$person->id,$person->lname,array('class'=>'form-control', 'placeholder'=>'lname')) }}
</li>
#endforeach
<li class="list-group-item">
<div class="box-footer">
<button type="submit" class="btn btn-primary">Update</button>
</div>
</li>
{{ Form::close() }}
</ul>
</div>
</div>
#stop
The routes:
<?php
Route::get('/', array('as'=>'home', 'uses'=>'HomeController#index'));
Route::post('/', array('as'=>'personUpdate', 'uses'=>'HomeController#updatePersons'));
I have tried to use the savemany() function on $persons after the foreach loop in updatePersons() but with no results.
If you're updating many rows with each with different values, there's no easier way to do it.
Could you think of how you'd write this in SQL?

In category counts his item from database table

$r = DB::table('sub_category')->select('*')->where('cat_id', $id)
->where('sub_status', '1')->orderBy('sub_id', 'asc')->get();
$name = DB::table('category')->where('cat_id', $id)->get();

I think you are closing the PHP tag in the wrong place. Change to this:
<?php print_r($count);
$data = $this->BasicController->count {{ ($row->sub_id) }}
echo $data['count'];//here is the rightplace to close your PHP ?>
</span></div>
All PHP code needs to stay between the <?php and ?>
Looking to your image, apparently, it's printing the $count and then it's printing the plain text , so you have 80$data = ...
If you counted your rows in controller by the code below
$count = DB::table('products')->where('sub_id', $id)->count();
then why wrote so many code in html for counting?
Remove all code form counting form your html and just use this {{ $count }}

Loop Object Relationship Laravel

Here i'm trying to to loop through all my users with their related assignments. I have made the User->Assignment Relationship in the model. When I dd($students) I receive the array of students with their related assignments, however when I view this on the page I do not receive the loop of assignments. What could I have missed in the code? Im sure it's somewhere in the html I messed up.
User Model:
public function assignments()
{
return $this->hasMany('App\Assignment');
}
Assignment Model:
public function userAssignment()
{
return $this->belongsTo('App\User');
}
Controller:
$students = User::where('position','student')->with('assignments')->get();
Html:
#foreach($students as $student)
<div class="item{{{ $isFirst ? ' active' : '' }}}">
<div class = "deck">
<div class = "row marg">
<div class="col-md-8">
<div class = "stdnt">
<h1>Student Info</h1>
<h1>{{$student->name}}</h1>
<p>Program: {{$student->pack}}</p>
<p>Level: {{$student->level}}</p>
<p>Status: {{$student->status}}</p>
<p>Lesson: {{$student->lesson}}</p>
</div>
</div>
<div class = "col-md-4">
<div class = "teac">
<h1>Teacher Info</h1>
<h1>{{$student->teacher}}</h1>
<p>Picture</p>
<p>assign form</p>
<p>assign button</p>
</div>
</div>
</div>
</div>
<div class = "mask flow">
<div class = "row-fluid marg">
#foreach($student->assignments() as $assignment)
<div class = "ablock">
<h1>{{$assignment->title}}</h1>
<p>{{$assignment->created_at}}</p>
<p>{{$assignment->type}}</p>
<p>{{$assignment->body}}</p>
</div>
#endforeach
</div>
</div>
{{--*/ $isFirst = false; /*--}}
</div>
#endforeach
Don't call the assignments method. Simply access it as a property:
#foreach($student->assignments as $assignment)
// ^^
#endforeach
