Introduction
The Eloquent ORM included with Laravel provides you with an easy way of interacting with your database. This simplifies all CRUD (Create, read, update, and delete) operations and any other database queries.
As described in the official Laravel documentation, Eloquent expects the created_at
and updated_at
columns to exist on your model's corresponding database table.
However, in some specific cases you might not have those two tables in place.
In this tutorial, you will learn how to fox the Laravel Unknown Column 'updated_at'
error by disabling the Laravel timestamps for a specific model!
Prerequisites
Before you start, you would need to have a Laravel application up and running.
I will be using a DigitalOcean Ubuntu Droplet for this demo. If you wish, you can use my affiliate code to get free $100 DigitalOcean credit to spin up your own servers!
If you do not have that yet, you can follow the steps from this tutorial on how to do that:
Or you could use this awesome script to do the installation:
Disable the timestamp columns in your Model
In order to disable the timestamp columns for a specific model, all that you would need to do is define the a public property called $timestamps
and set this to false.
That way, when you try to update your model, you will not get the Unknown Column 'updated_at'
error.
Let's have a model called Video
as an example:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Video extends Model
{
// Disable the model timestamps
public $timestamps = false;
}
With that, Eloquent will no longer be looking for the created_at
and the updated_at
columns.
Change the name of the timestamp tables
In order cases, you might have the timestamp columns present, but with different names, so you would not want to disable the timestamps
but instead specify the correct names of the tables.
To do so, all that you have to do is specify the following two constants in your Model:
<?php
class Video extends Model
{
const CREATED_AT = 'creation_date';
const UPDATED_AT = 'updated_date';
}
Adjust the contestants accordingly depending on your needs
That way, Eloquent will be looking for a updated_date
table rather than updated_at
as default.
