what is the difference between $model properity and newFactroy method in laravel factroy

i have a question regarding why do we need to set protected $model = User::class when defining a Factory and in the model itself we need sometimes (if we did not use a convention for Factory name ) to override newFactory method to tell the model about the Factory ? why we need both of them ? why not to use $model properity only ? or newFactory() only ? why both of them ??

      class UserFactory extends Factory{
protected $model = User::class;
}

and inside the model

   public static function newFactory(){
        return UserFactory::new();
 }

How to make laravel offline app through which user download from play store and it is offline

I want to make attendance management app (which is built with laravel) work offline...but I cant found out how to do it!

What i use for static files, but i am not sure exactly how to handle the dynamic side of the app.

The app uses a database which i am guessing I need to use localStorage for? (from what i have read online so far)

Im basically just looking for someone to point me in the right direction as i am struggling to find much online on setting up Laravel for use offline.

thanks for helping me.

FormData jQuery AJAX Returning Null

I am trying to use FormData() for sending texts and images. It's not working

$('#saveBtn').click(function(e) {
        e.preventDefault();
        $.ajaxSetup({
            headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            }
        });

        var formDataEdit = new FormData();

        //formDataEdit.append('images', $('#images')[0].files[0]); // for single item
        formDataEdit.append('nameForEdit', $("input[name='nameForEdit']")
            .val());
        formDataEdit.append('codeForEdit', $('#codeForEdit').val());
        formDataEdit.append('categoriesForEdit', $('#categoriesForEdit').val());
        formDataEdit.append('stokForEdit', $('#stokForEdit').val());

        let TotalImages = $('#photoForEdit')[0].files.length; //Total Images
        let images = $('#photoForEdit')[0];
        for (let i = 0; i < TotalImages; i++) {
            formDataEdit.append('images' + i, images.files[i]);
        }
        formDataEdit.append('TotalImages', TotalImages);

        console.log(formDataEdit.get('nameForEdit')); // it's works, returning the value of name. 
        console.log(formDataEdit.append('codeForEdit', $('#codeForEdit')
            .val())); // it's not working. Returning undefined. */

        $.ajax({
            url: "products/" + id,
            method: 'PUT',
            data: formDataEdit,
            enctype: 'multipart/form-data',
            cache: false,
            contentType: false,
            processData: false,
            dataType: 'JSON',
            async: true,
            headers: {
                'Content-Type': undefined,
            },
            xhr: function() {
                myXhr = $.ajaxSettings.xhr();
                return myXhr;
            },
            success: function(result) {
                if (result.errors) {
                    $('.alert-danger').html('An error in your input fields');
                    $.each(result.errors, function(key, value) {
                        $('.alert-danger').show();
                        $('.alert-danger').append('<strong><li>' + value +
                            '</li></strong>');
                    });
                } else {
                    $('.alert-danger').hide();
                    $('.alert-success').show();
                    $('.datatable').DataTable().ajax.reload();
                    setInterval(function() {
                        $('.alert-success').hide();
                        $('#ajaxModel').hide();
                        location.reload();
                    }, 2000);
                }
            },
            error: function(response) {
                $('#codeError').text(response.responseJSON.errors.code);
                $('.alert-danger').html('An error in your input fields');
                $.each(response.errors, function(key, value) {
                    $('.alert-danger').show();
                    $('.alert-danger').append('<strong><li>' + value +
                        '</li></strong>');
                });
            }
        });
    });

Everytime I use dd($request->get('stokForEdit')) for example, it's returning null

But, when I change code to below without FormData(), it's working.

url: "products/" + id,
        method: 'PUT',
        data: {
                nameForEdit: $('#nameForEdit').val(),
                codeForEdit: $('#codeForEdit').val(),
                categoriesForEdit: $('#categoriesForEdit').val(),
                stokForEdit: $('#stokForEdit').val(),
        },
        enctype: 'multipart/form-data',
        cache: false,
        //contentType: false,
        //processData: false,
        dataType: 'JSON',
        async: true,
        headers: {
            'Content-Type': undefined,
        },
        xhr: function() {
            myXhr = $.ajaxSettings.xhr();
            return myXhr;
        },

I can't use the second way, because I need to send an images. Help me with the soultion!

can't run laravel 5.7 on php8

hi guys I need help for this case I can't run laravel 5.7 on php8, when I do "php artisan serve" I got error:

thrown in /var/www/html/myProject/vendor/laravel/framework/src/Illuminate/Container/Container.php on line 838
PHP Fatal error:  Uncaught ErrorException: Method ReflectionParameter::getClass() is deprecated in /var/www/html/myProject/vendor/laravel/framework/src/Illuminate/Container/Container.php:838

I have tried to update composer required php version form "^7.1.3" to "php": "^7.1.3|^8.0", and when I run composer update I got another error.

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/framework[v5.7.0, ..., 5.7.x-dev] require php ^7.1.3 -> your php version (8.0.3) does not satisfy that requirement.
    - Root composer.json requires laravel/framework 5.7.* -> satisfiable by laravel/framework[v5.7.0, ..., 5.7.x-dev].

I hope any body sharing what is solution for this case

Laravel queues are not processing automatically until I run php artisan queue:work command

I came through multiple solutions on stack overflow but no luck. It worked fine before 1 month but now a days it is not working.

I am using Ubuntu Os and nginx server. For queue driver I used redis Here is my redis configuration in .env

BROADCAST_DRIVER=log
CACHE_DRIVER=redis
SESSION_DRIVER=file
QUEUE_DRIVER=redis

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

I also used supervisor to monitor and here is my configuration for supervisor

[program:worker-326242]
command=php7.4 /home/forge/myapp.com/artisan queue:work redis --sleep=10 --daemon --quiet --tries=3 --env=production --queue="default"

process_name=%(program_name)s_%(process_num)02d
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
user=forge
numprocs=1
stdout_logfile=/home/forge/.forge/worker-326242.log

The problem is queue jobs are not executing automatically but it works when i run the command "php artisan queue:work"

Please ignore my poor english. Any help will be appriciated
