Laravel: Overcoming the Unknown Column 'updated_at' Error

Laravel, one of the most popular PHP frameworks, often delights developers with its powerful and smooth features. However, like any complex system, it can sometimes present unexpected issues. One such issue is the Unknown column 'updated_at' error. Let's delve into what causes this error and how you can resolve it. Additionally, we'll touch on checking if a column exists using Laravel Excel.

Understanding the Error

The Unknown column 'updated_at' error typically occurs in Laravel when the framework expects the presence of a timestamps column in your database, but it is missing. By default, Laravel includes created_at and updated_at columns in the migration schema for tracking when a record is created and last updated.

If your table, for some reason, does not include these columns, Laravel will throw an error when trying to perform any operations involving these timestamps.

How to Resolve the Error

To resolve this error, there are a few approaches you can take:

Add the updated_at Column:
If tracking the updated timestamp is necessary for your application, add the updated_at column to your table.
