How to create a CRUD in Laravel?
Developing robust and efficient systems is key in today's technological world. Laravel, a highly popular PHP framework, simplifies this process with its organized architecture and tools. In this lesson, we explore how to create a CRUD (Create, Read, Update, Delete) in Laravel, an essential function for manipulating databases.
How to configure the database?
To begin with, it is essential to have a database configured in your Laravel project. We will use a MySQL database and we must follow the following steps:
- Create the database: In your MySQL client, create a database, for example,
crud_laravel
.
- Configure Laravel: Edit the
.env
file in the root of your project. Configure the variables for the database such as name, user and password.
DB_CONNECTION=mysqlDB_HOST=127.0.0.1DB_PORT=3306DB_DATABASE=crud_laravelDB_USERNAME=your_userDB_PASSWORD=your_password
How to perform migrations in Laravel?
Migrations are essential to define the structure of the tables in your database programmatically. They avoid manipulating the database directly, which is useful when you work in a team:
-
See available commands: In the terminal, run:
php artisan
Here you will see all available commands.
-
Migrate tables: Laravel includes default tables such as users
. Run the migrate command to create these tables:
php artisan migrate
How to configure routes in Laravel?
In Laravel, routes determine how HTTP requests are handled:
-
Modify default routes: in the routes/web.php
file, delete example routes and configure the necessary ones:
Route::get('/', 'UserController@index'); Route::post('/store', 'UserController@store')->name('users.store'); Route::delete('/destroy/{id}', 'UserController@destroy')->name('users.destroy');
What is a controller and how to create it?
A controller acts as an intermediary between the model and the view. It contains the logic to handle HTTP requests passing through routes:
-
Create a controller with Artisan: Use the following command to create a controller:
php artisan make:controller UserController.
-
Add methods in the controller: Define the methods corresponding to the routes in the controller:
public function index() { }
public function store() { }
public function destroy($id) { }
What is the workflow in Laravel?
Here's a general way to work with Laravel:
- Designing routes: The first step as programmers is to define routes.
- Define controllers: Create controllers that contain the logic to handle the requests.
- Write the logic: Implement the logic in the methods of the controllers.
- Migrate changes: Make migrations to modify the database structure.
