Managing data in a Laravel application is a critical task to ensure optimal performance and prevent database clutter. In this guide, we’ll explore how to automatically delete data that is older than 30 days from your Laravel application’s database. We’ll use a Laravel controller and Eloquent to achieve this task efficiently.
Understanding the Code
The provided code snippet is a part of a Laravel controller named PostController
. It contains a method named index
, which is responsible for deleting data that is 30 days old.
Here’s a breakdown of the code.
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Models\Post;
First, we import the necessary dependencies, including the Post
model, which presumably represents the data we want to delete.
public function index(Request $request)
{
Post::whereDate('created_at', '<=', now()->subDays(30))->delete();
}
Inside the index
method, we execute a database query using Eloquent. Here’s how it works:
- We use the
Post
model to interact with the database. - The
whereDate
method filters the records based on thecreated_at
column of thePost
model. - We specify that we want to delete records where the
created_at
date is less than or equal to the current date minus 30 days, achieved usingnow()->subDays(30)
. - Finally, the
delete
method is called to remove the selected records from the database.
Implementing the Automatic Deletion Process
To make this code execute automatically, you can use Laravel’s task scheduling feature. Here’s how to set it up:
- Open the
app/Console/Kernel.php
file in your Laravel project. - In the
schedule
method, add the following code to schedule theindex
method ofPostController
to run daily.
protected function schedule(Schedule $schedule)
{
$schedule->call([new \App\Http\Controllers\PostController, 'index'])->daily();
}
- Save the file.
Now, Laravel will automatically run the index
method of the PostController
daily. This means that any data in the Post
model’s table that is older than 30 days will be deleted automatically.
