Introduction
CRUD operations are a fundamental part of web development, and Laravel 9 provides an easy and efficient way to perform these operations. This tutorial will guide you through the process of creating a simple CRUD application using Laravel 9.
Prerequisites
Before we dive into the tutorial, there are a few prerequisites you need to have installed on your system:
- PHP 7.3 or higher
- Composer
- MySQL or any other database management system
Setting up a new Laravel 9 project
The first step is to set up a new Laravel 9 project. You can do this by running the following command in your terminal:
composer create-project --prefer-dist laravel/laravel blog
This will create a new Laravel 9 project called "blog" in your current directory.
Creating the database
The next step is to create a new database for our application. You can do this using your database management system of choice. Once you have created the database, you will need to update the .env file in your Laravel project with the correct database credentials.
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_crud
DB_USERNAME=root
DB_PASSWORD=
Make sure to replace the database name, username, and password with your own credentials.
Creating the Model
Now that we have set up the database, we need to create a model for our application. In Laravel, models are used to interact with the database. To create a new model, run the following command in your terminal:
php artisan make:model Post
This will create a new model called "Post" in your Laravel project. You can find the model in the app/Models directory.
Creating the Migration
The next step is to create a migration for our database table. Migrations are used to create and modify database tables. To create a new migration, run the following command in your terminal:
php artisan make:migration create_posts_table --create=posts
This will create a new migration called "create_posts_table" in your Laravel project. You can find the migration in the database/migrations directory.
Creating the Controller
Now that we have created the model and migration, we need to create a controller for our application. Controllers are used to handle incoming requests and return responses. To create a new controller, run the following command in your terminal:
php artisan make:controller PostController --resource
This will create a new controller called "PostController" in your Laravel project. The --resource flag tells Laravel to generate a controller with RESTful methods for CRUD operations.
Creating the Views
The final step is to create the views for our application. Views are used to display data to the user. To create a new view, run the following command in your terminal:
php artisan make:view index
php artisan makeThis will create two new views called "index.blade.php" and "create.blade.php" in the resources/views/posts directory. The index.blade.php view will display a list of all the posts, and the create.blade.php view will display a form for creating a new post.
Testing the CRUD operations
Now that we have created all the necessary files for our application, it's time to test the CRUD operations. Start by running the following command in your terminal to start the development server:
php artisan serve
This will start the development server on http://localhost:8000.
Creating a new post
To create a new post, go to http://localhost:8000/posts/create in your browser. You should see a form for creating a new post. Fill in the form with some dummy data and click the "Create Post" button. You should be redirected to the home page, and you should see your new post in the list.
Viewing a post
To view a post, click on its title in the list on the home page. You should be taken to a new page that displays the post's details.
Updating a post
To update a post, click on the "Edit" button next to its title on the home page. You should be taken to a form for editing the post's details. Make some changes to the post and click the "Update Post" button. You should be redirected to the post's details page, and you should see the updated information.
Deleting a post
To delete a post, click on the "Delete" button next to its title on the home page. You should be asked to confirm the deletion. Once you confirm, the post should be deleted, and you should be redirected to the home page.
Conclusion
In this tutorial, we learned how to perform CRUD operations using Laravel 9. We created a new Laravel 9 project, set up the database, created a model, migration, controller, and views, and tested the CRUD operations. Now that you have a basic understanding of how CRUD operations work in Laravel 9, you can use this knowledge to build more complex applications.
