Building a Simple CRUD Application in Laravel


CRUD (Create, Read, Update, Delete) operations are the foundation of most web applications. In Laravel, creating a CRUD application is a straightforward process thanks to the framework's powerful features. In this guide, we'll walk through building a simple CRUD application in Laravel, allowing you to perform these essential operations on a database.


Prerequisites


Before we start, make sure you have the following prerequisites in place:


  • Laravel Installation: You should have Laravel installed on your system. If not, follow the installation instructions in the Laravel documentation.
  • Database Setup: Create a database and configure your Laravel project to use it by updating the `.env` file with your database credentials.

Step 1: Create a Model


Start by creating a model for your application. In your terminal, use Artisan to generate a model. For this example, let's create a `Task` model:


        
php artisan make:model Task -m

This command generates a `Task` model and a migration file for the corresponding database table. The `-m` option indicates that a migration file should be created for the model.


Step 2: Define the Migration


Open the generated migration file (located in the `database/migrations` directory) and define the table schema. For our `Task` model, we might define a table with fields like `id`, `title`, `description`, and `completed`. Then, run the migration to create the table:


        
php artisan migrate

Step 3: Create a Controller


Create a controller to handle CRUD operations for your `Task` model. Run the following Artisan command to generate a `TaskController`:


        
php artisan make:controller TaskController

The generated controller will contain methods for creating, reading, updating, and deleting tasks.


Step 4: Define Routes


Open your `routes/web.php` file and define routes for the CRUD operations. Here's an example of how to define routes for a `TaskController`:


        
Route::resource('tasks', 'TaskController');

This single line of code defines routes for all CRUD operations, including creating, reading, updating, and deleting tasks.


Step 5: Create Views


Create Blade views for your CRUD operations. In your `resources/views` directory, create views for listing tasks, creating tasks, editing tasks, and displaying task details. Use Blade templates to display dynamic data.


Step 6: Implement Controller Methods


In your `TaskController`, implement methods to handle CRUD operations. For example, you can define a `create` method to show the task creation form and a `store` method to save a new task to the database. Use Eloquent models to interact with the database.


Step 7: Display Data in Views


In your views, use Blade templating to display data from your controller methods. Create forms for creating and editing tasks, and list tasks in a table or list view.


Step 8: Test Your Application


Finally, test your CRUD application by accessing the defined routes in your web browser. Ensure that you can create, read, update, and delete tasks as expected.


Conclusion


Building a simple CRUD application in Laravel is an excellent way to get started with the framework. It demonstrates the power of Laravel's features, including models, migrations, controllers, and views. As you become more comfortable with Laravel, you can explore advanced topics like authentication, validation, and more complex relationships between models.
