=================
use App\Models\prod2;
$model = new prod2();
Добавление:
==============
php artisan make:model UserModel -m
или
php artisan make:model Contact -m
Здесь команда -m обозначает создание файла миграции вместе с файлом модели.
Это есть - хорошо.
В миграции потом нужно прописать например:
/**
* Run the migrations.
*/
public function up(): void
{
Schema::create('prod2s', function (Blueprint $table) {
$table->id();
$table->string('nazv');
$table->string('cena');
$table->string('vers');
$table->text('mes');
$table->timestamps();
});
}
Затем:
Когда все будет готово выполните команду миграции и очистки кэша:
php artisan migrate
1. Оно не разрешило без кавычек в пароле, так-как там было #
2. Заставил прописать вот это:
/config/database.php
'mysql' => [
...,
...,
'engine' => env('DB_ENGINE', 'InnoDB'),
]
3. Сказал что я хочу создать таблицу повторно. Пришлось удалить все таблицы
php artisan cache:clear

Написано что без Компосера тоже можно установить.
sudo apt install php-mysql php-mbstring php-tokenizer php-xml php-json php-common
- если это всё установлено - то оно сразу об этом скажет.
Нужно перейти в папку куда будите устанавливать этот самый Ларавел. Я сделал не правельно и установил всё в папку по инструкции /var/www/sites. Так тоже можно, но как к ней обращаться потом с Апачи?
sudo composer create-project --prefer-dist laravel/laravel laravelapp
ln -s ./laravelapp/public public_html
на домен устанавливается быстро
- устанавливается очень долго и скачивает около 50МБ в распакованном виде.
Установит всё в папку laravelapp
БД получается что не нужна. Я создал БД и таблицу и прописал её в настройках, но там всё осталось нетронутым.
php artisan serve - запускает свой, внутренний сервер. Команда работает только из корня установки сайта!
Сразу есть файл:
\resources\views\welcome.blade.php
В нем работает Твиг и команды ЛАревел. Он на главной.
И php во Вьюхах тоже работает! То есть достаточно Ларевел использовать как маршрутизатор и внутренние команды и Твиг!!!
Создание адреса:
в файле:
\routes\web.php
Route::get('/', function () {
return view('home');
});
Route::get('/about', function () {
return view('about');
});
Route::get('/contact', function () {
return view('contact');
});
Эти все пути будут искать соответствующие файлы-Вьюхи в \resources\views\ с расширением .blade.php
------------------------
https://riptutorial.com/laravel/example/29382/hello-world-example-with-v...
1. В resources/views создать файл helloview.blade.php с <h1>Hello, World</h1> - Вьюха, view, Представление
2. cd your_laravel_project_root_directory
$> php artisan make:controller HelloController - это создаст файл app/Http/Controllers/HelloController.php
3. Его нужно дополнить, а точнее написать - потому как это просто пустой Класс, шаблон, заготовка. Пишем туда:
public function hello(){
return view('helloview');
}
4. В routes/web.php нужно прописать: Route::get('/helloworld', 'App\Http\Controllers\HelloController@hello');
Это у них называется Роутер.
Вот столько плясок с Бубном чтоб вывести одну строку.
================
Отслеживание URL
Laravel предоставляет класс Route для отслеживания всех URL адресов в проекте. Отслеживание адресов необходимо прописывать в файле /routes/web.php
<?php
Route::get('/users', function () {
return view('users');
});
Здесь указывается URL адрес что отслеживается, а также шаблон, что будет вызван при переходе на URL адрес.
