CRUD stands for Create, Read, Update, and Delete, a set of operations used to manipulate data in an application. CRUD applications manage data in databases, such as entries in a contact list or product catalog. These applications are usually user-friendly and provide an efficient way of collecting data.
Laravel 9 is a popular open-source web framework for creating applications with PHP. It is based on the MVC (Model-View-Controller) design pattern and provides an easy way to create potent web applications. With Laravel 9, developers can quickly create robust web apps with authentication, routing, validation, and more features.
Setting up the Project
Before you begin working on the project, a few things need to be done first. First, you will need to make sure you have the necessary prerequisites installed on your machine. This includes a web server such as Apache or Nginx, a database such as MySQL or PostgreSQL, and PHP 7.4 or higher.
Once you have all the prerequisites installed, you can install Laravel 9. You can do this by running the following command in your terminal:
composer create-project laravel/laravel project_name --prefer-dist
This will install Laravel 9 in the folder named “project_name”. Once the installation is complete, you can move into the project directory and start working on the project.
The next step is to create the project. This can be done by running the following command in your terminal:
php artisan make:project project_name
This will create the necessary files and folders for the project and set up the environment.
Database Setup
The next step is to configure the database for the project. You can do this by editing the “.env” file in the root directory of your project. This file contains all the configuration settings for your project, including database settings such as hostname, username, password, and database name. Make sure to save the file after making any changes.
Once the database is configured, you can create the necessary migrations for the project. Migrations are used to define the structure of the database tables and columns. You can create a migration with the following command:
php artisan make:migration create_table_name_table --create=table_name
This will create a new migration file with the specified table name. After creating the migration file, you can add columns to it by using Eloquent ORM methods such as $table->string('column_name');. Once you have finished creating all your migrations, you can run them with the following command:
php artisan migrate
This will create all of your tables in your database.
You may also want to seed your database with fake data. To do this, you can use seeds. Seeds are used to generate mock data for testing purposes. You can create a seed with the following command:
php artisan make:seed TableNameSeeder
After creating your seed file, you can add mock data to it using Eloquent ORM methods such as $table->insert([…]);. Once you have finished creating all your seeds, you can run them with the following command:
php artisan db:seed
This will populate your database with mock data.
Models
Models represent data in an application and are usually based on a particular table in a database. In Laravel 9, models are created with Eloquent ORM, which provides an easy way to interact with databases and perform operations such as creating, updating, deleting, and more. For example, to create a model in Laravel 9, you can use the following command:
php artisan make:model ModelName
This will create a new model class with the specified name. Once you have created your model class, you can add attributes to it using Eloquent ORM methods such as $table->string('column_name');. You may also want to add mass assignment protection to your model by using the $fillable property or $guarded property. Mass assignment protection prevents malicious users from sending unwanted data to your application by limiting which attributes can be set when creating or updating records in your application.
Routes
Routes are used to define how users interact with your application and define which controller should handle each request. In Laravel 9, routes are defined in the “routes/web.php” file and use HTTP verbs such as GET, POST, PUT and DELETE to define how users should interact with your application. To create a route in Laravel 9, you can use the following syntax:
Route::get('/', 'ControllerName@methodName');
The first parameter defines the URL that should be matched when this route is requested and the second parameter defines which controller should handle this request and which method should be called on that controller.
Once you have defined all of your routes, you will need to define a controller for each route. Controllers are classes that contain methods that handle requests from users. To create a controller in Laravel 9, you can use the following command:
php artisan make:controller ControllerName
This will create a new controller class with the specified name. Once you have created your controller class, you can add methods to it that handle requests from users.
Views
Views are used to render HTML responses for requests from users and are usually based on templates or layouts. In Laravel 9, views are created with Blade templating engine which provides an easy way to mix HTML content with PHP code and display dynamic content on webpages. To create a view in Laravel 9, you can use the following command:
bash php artisan make:view viewName
This will create a new view template with the specified name inside of the “resources/views” directory. Once you have created your view template, you can add HTML content to it as well as Blade directives such as @foreach() or @if() to display dynamic content based on user input or other conditions.
Conclusion
In this tutorial we have gone over how to build a CRUD application using Laravel 9 by setting up our project, configuring our database, creating models and routes, creating views and more. By working through this tutorial we have seen how easy it is to build powerful web applications using Laravel 9 and its vast collection of tools and features.
