I need to export over 100K records to Excel from database using Maatwebsite Laravel excel 3.1 plugin, the problem is that I get data as an array.
$data = $this->client->getData("sc/asistencia-social/informe",$request->all());
return (new ExcelExport($data))->store('myFile.xlsx'); //using FromQuery
My ExcelExport Class :
<?php
namespace App\Exports;
use Maatwebsite\Excel\Concerns\FromQuery;
use Maatwebsite\Excel\Concerns\Exportable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\SerializesModels;
class ExcelExport implements FromQuery
{
use Exportable, SerializesModels;
private $data;
public function __construct($data)
{
$this->data = $data; //Inject data
}
public function query()
{
return $this->data;
}
}
Actually, I get a "Call to a member function chunk() on array" error.
I even tried to convert it into a collection with no success. Is there any possible solution to this.
You have created your export class as FromQuery export class. instead create a FromArray export class.
Note the Implement interface and the function name
class ExcelExport implements FromArray // this was FromQuery before
{
use Exportable, SerializesModels;
private $data;
public function __construct($data)
{
$this->data = $data; //Inject data
}
public function array(): array // this was query() before
{
return $this->data;
}
}
You should use shouldQueue to export large data to an Excel file.
It Worked
In Query remove ->get() or replace with ->paginate(100)
with maatwebsite queue export.

i want to export only today's record from my table not whole data, i used Carbon also it didnt work and it just simply export empty excel file. here i am sharing my code snap please help me.
i am using laravel 7 and latest version of laravel-Excel package.
<?php
namespace App\Exports;
use App\CosQueue;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\ShouldAutoSize;
use Maatwebsite\Excel\Concerns\WithStyles;
use PhpOffice\PhpSpreadsheet\Worksheet\Worksheet;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\AfterSheet;
use Carbon\Carbon;
class CosQueueExport implements FromCollection, WithHeadings, ShouldAutoSize, WithEvents
{
/**
* #return \Illuminate\Support\Collection
*/
public function collection()
{
$todaydate = date('Y-m-d');
return CosQueue::get(array('full_name', 'job_title','meeting_with','subject','date'))->where('created_at',$todaydate);
}
public function headings():array{
return[
"اسم",
'وظیفه',
'ملاقات با',
'موضوع',
'تاریخ'
];
}
public function registerEvents(): array
{
return [
AfterSheet::class => function(AfterSheet $event) {
$cellRange = 'A1:W1'; // All headers
$event->sheet->getDelegate()->getStyle($cellRange)->getFont()->setSize(14);
$event->sheet->getDelegate()->getStyle($cellRange)->getFont()->setName('calibri');
},
];
}
}
You can do one of these
public function collection()
{
// Carbon::today() === today()
return CosQueue::whereDate('created_at', Carbon::today())->get(array('full_name', 'job_title','meeting_with','subject','date'));
}
Also, you can do
public function collection()
{
return CosQueue::whereDate('created_at', date('Y-m-d'))->get(array('full_name', 'job_title','meeting_with','subject','date'));
}
After creating several Apps with Laravel and using softDelete properties I realized that methods like destroy(), restore() and kill() are exactly the same among several controllers. Therefore I am trying to put themn in a trait and use it from diferent Controllers.
My code is as follows:
ProfilesController.php
<?php
namespace App\Http\Controllers;
use App\Profile;
class ProfilesController extends Controller
{
public function destroy(Profile $profile)
{
Profile::del($profile, 'profiles');
return redirect()->route('profiles.index');
}
public function trashed()
{
Profile::trash('Profile');
}
}
Profile.php (model)
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Profile extends Model
{
protected $fillable = ['user_id', 'role_id', 'title', 'subtitle', 'slug', 'birthday', 'about'];
use SoftDeletes, Helpers, commonMethods;
public function getRouteKeyName()
{
return 'slug';
}
// ... more code here
}
trait file: commonMethods.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Auth;
use App\Profile;
use Session;
trait commonMethods
{
public static function del($element, $page_name)
{
$element->delete();
Session::flash('success', $element . ' successfully deleted!');
}
public static function trash($model)
{
$total = $model::onlyTrashed()->get();
$total_tr = count($total);
$all_tr = $model::all();
return view('partials.templates.trashed', compact('total', 'total_tr', 'all_tr'));
}
// ...more code here
}
The problem:
I try to visit the view "Trashed" that will list all elements "softdeleted" but not "killed", the method.
I pass the $model variable with the method trash($model)
I get the following error:
Class App/Profile does not found. Try to call App/Profile
I have debugged and the $model variable contains exactly what I need, the string 'Profile' which is what I need to build the Query:
$total = Profile::onlyTrashed()->get();
This query works while in the ProfilesController, but does not work while in a trait, since the model class is not found.
Any idea how could I make it work?
I am using Laravel 6.
If you need to use a class as a string you will want to use its full name. 'App\Profile' instead of 'Profile'.
$model = 'Profile';
new $model; // will use `\Profile`
$model = 'App\Profile';
new $model; // will use '\App\Profile';
In your controller( ProfilesController ) write :
use App\Profile;
In your model write :
use App\commonMethods;
I am trying to make a notification system in my project.
These are the steps i have done:
1-php artisan notifications:table
2-php artisan migrate
3-php artisan make:notification AddPost
In my AddPost.php file i wrote this code:
<?php
namespace App\Notifications;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
class AddPost extends Notification
{
use Queueable;
protected $post;
public function __construct(Post $post)
{
$this->post=$post;
}
public function via($notifiable)
{
return ['database'];
}
public function toArray($notifiable)
{
return [
'data'=>'We have a new notification '.$this->post->title ."Added By" .auth()->user()->name
];
}
}
In my controller I am trying to save the data in a table and every thing was perfect.
This is my code in my controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Post;
use App\User;
//use App\Notifications\Compose;
use Illuminate\Notifications\Notification;
use DB;
use Route;
class PostNot extends Controller
{
public function index(){
$posts =DB::table('_notification')->get();
$users =DB::table('users')->get();
return view('pages.chat',compact('posts','users'));
}
public function create(){
return view('pages.chat');
}
public function store(Request $request){
$post=new Post();
//dd($request->all());
$post->title=$request->title;
$post->description=$request->description;
$post->view=0;
if ($post->save())
{
$user=User::all();
Notification::send($user,new AddPost($post));
}
return redirect()->route('chat');
}
}
Everything was good until I changed this code:
$post->save();
to this :
if ($post->save())
{
$user=User::all();
Notification::send($user,new AddPost($post));
}
It started to show an error which is:
FatalThrowableError in PostNot.php line 41: Call to undefined method
Illuminate\Notifications\Notification::send()
How can i fix this one please??
Thanks.
Instead of:
use Illuminate\Notifications\Notification;
you should use
use Notification;
Now you are using Illuminate\Notifications\Notification and it doesn't have send method and Notification facade uses Illuminate\Notifications\ChannelManager which has send method.
Using this
use Illuminate\Support\Facades\Notification;
instead of this
use Illuminate\Notifications\Notification;
solved the problem for me.
Hope this helps someone.
using this is better
use Notification
Instead of
use Illuminate\Support\Facades\Notification
this makes the send() not accessible [#Notification Databse]
I need to pass a collection to every view; the collection contains the IDs of the items in the user's shopping cart. I've tried Service Providers and a BaseClass but neither worked as (apparently) Auth hasn't been registered at those points and only returns null.
What's the best way get records from an authenticated user and pass it to every view?
Edit: here's the relevant code
User.php
public static function getCart()
{
if (Auth::guest()) {
return [];
}
$collection = new \Illuminate\Database\Eloquent\Collection();
$collection = Auth::user()->cart()->pluck('post_id');
return $collection;
}
CartServiceProvider.php
namespace App\Providers;
use View;
use App\User;
use Illuminate\Support\ServiceProvider;
class CartServiceProvider extends ServiceProvider
{
public function boot()
{
View::share('cart', User::getCart());
}
public function register()
{
//
}
}
In any view...
<?php dd($cart); ?>
returns [] because Auth hasn't been registered yet, so the empty array is returned.
Found the answer on Laracasts and it seems to work quite well.
https://laracasts.com/discuss/channels/general-discussion/l5-service-provider-for-sharing-view-variables
From the OP #imJohnBon: "I managed to solve this issue by creating 2 files. First a ComposerServiceProvider which uses a wildcard to be applied to every view and not just particular views:"
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Contracts\View\Factory as ViewFactory;
class ComposerServiceProvider extends ServiceProvider {
public function boot(ViewFactory $view)
{
$view->composer('*', 'App\Http\ViewComposers\GlobalComposer');
}
public function register()
{
//
}
}
"And then the corresponding GlobalComposer where I share variables that should be available in all views:"
namespace App\Http\ViewComposers;
use Illuminate\Contracts\View\View;
use Illuminate\Support\Facades\Auth;
class GlobalComposer {
public function compose(View $view)
{
$view->with('currentUser', Auth::user());
}
}
I have created trait as follows on this page app/Traits/ModelEventThrower.php
namespace App\Traits;
use Input;
use Event;
use App\Events\ActivityLog;
use Illuminate\Database\Eloquent\Model;
//use Illuminate\Support\Facades\Event;
/**
* Class ModelEventThrower
* #package App\Traits
*
* Automatically throw Add, Update, Delete events of Model.
*/
trait ModelEventThrower {
/**
* Automatically boot with Model, and register Events handler.
*/
protected static function bootModelEventThrower()
{
foreach (static::getModelEvents() as $eventName) {
static::$eventName(function (Model $model) use ($eventName) {
try {
$reflect = new \ReflectionClass($model);
echo "here";exit;
} catch (\Exception $e) {
return true;
}
});
}
}
/**
* Set the default events to be recorded if the $recordEvents
* property does not exist on the model.
*
* #return array
*/
protected static function getModelEvents()
{
if (isset(static::$recordEvents)) {
return static::$recordEvents;
}
return [
'created',
'updated',
'deleted',
];
}
}
My City Model is something like this
namespace App;
use App\Traits\ModelEventThrower;
use App\Events\ActivityLog;
use Illuminate\Database\Eloquent\Model;
use Event;
class City extends Model
{
use ModelEventThrower;
//protected static $recordEvents = ['updated'];
...
}
My CitiesController is
namespace App\Http\Controllers\Admin;
use App\City;
use App\Country;
use Input;
use Validator;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class CitiesController extends Controller
{
......
public function update(City $city,Request $request)
{
......
$city->where('id','=',$input['id'])->update($input);
Somehow, I dont see its calling the function written in trait file. When I tried to create $city->create($input); it echos "here" and stops execusion, but not doing same for update function , however I could successfully update the records.
Any suggestion/help will be highly appreciated.
I had a similar issue with Laravel. By adding a constructor in the model to call the boot() function of the parent Model, like so:
public function __construct()
{
parent::boot();
}
you can make sure that all the traits are booted. This solved it for me.
