Timestamps management in Laravel - Mini Project: Build & Apply

Timestamps management

📖 Scenario: You are building a Laravel application that tracks blog posts. Each post needs to record when it was created and last updated automatically.

🎯 Goal: Create a Laravel Eloquent model for Post that uses timestamps to automatically manage created_at and updated_at fields.

📋 What You'll Learn

Create a Post model class

Enable automatic timestamps management

Add a property to disable timestamps in the model

Manually set a timestamp value for created_at

💡 Why This Matters

🌍 Real World

Many web applications need to track when records are created and updated. Laravel's timestamps feature helps automate this common task.

💼 Career

Understanding timestamps management is essential for backend developers working with Laravel to build maintainable and reliable data models.

1

Create the Post model with timestamps enabled

Create a Laravel Eloquent model class called Post that extends Model and uses automatic timestamps management by default.

Laravel

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

// Define the Post model class here

Need a hint?

Laravel Eloquent models have timestamps enabled by default, so you only need to create the class extending Model.

2

Add a property to disable timestamps

Inside the Post model class, add a public property $timestamps and set it to false to disable automatic timestamps.

Laravel

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    // Disable timestamps here
    
    // Your code here
}

Need a hint?

Set public $timestamps = false; inside the model class to turn off timestamps.

3

Manually set the created_at timestamp

In the Post model class, add a method called setCreatedAtManually that sets the created_at attribute to the current date and time using now().

Laravel

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    public $timestamps = false;

    // Add method to set created_at manually
    
    // Your code here
}

Need a hint?

Define a public method that assigns now() to $this->created_at.

4

Re-enable timestamps and finalize the model

Remove or comment out the $timestamps property to re-enable automatic timestamps in the Post model class.

Laravel

created_at = now();
    }
}

Need a hint?

Comment out or delete the public $timestamps = false; line to enable timestamps again.
