Rollback Migration Laravel | About
Laravel is a popular PHP framework. It offers several tools to manage database migrations.
Migrations act as a version control system for our database. They allow us to define and share the application’s database schema definition.
Today, we are going to explore how to roll back specific migrations in Laravel, including versions 6, 7, 8, and 9.
In addition, we will take a look at how to roll back all migrations using the command line.
Rolling Back the Last Migration
An easy way to roll back the latest migration is with the `migrate:rollback` command. This command rolls back the last “batch” of migrations, which usually includes multiple migration files. We can do this by running this command:
php artisan migrate:rollback
Rolling Back a Limited Number of Migrations
In case we are looking for a way to roll back a specific number of migrations, we can use the `–step` option with the `migrate:rollback` command.
For instance, we can roll back the last three migrations as seen below:
php artisan migrate:rollback –step=3
Rolling Back All Migrations
In order to roll back all migrations and revert our database to its initial state, we can use the `migrate:reset` command as seen here:
php artisan migrate:reset
Rolling Back Migrations from a Custom Path
Did you know that Laravel allows us to specify a custom path for our migrations?
For instance, if our migrations are located in a different directory, we can use the `–path` option with the `migrate:rollback` command to roll back specific migrations from that path.
In this scenario, we have to provide the full path to the migration file we want to roll back. Here’s an example:
php artisan migrate:rollback --path=/database/migrations/our-migration-file-name.php
Alternatively, we can also specify a specific migration file via its timestamp in the `–path` option. For example:
php artisan migrate:rollback --path=/database/migrations/2012_11_10_000000_create_users_table.php
Rolling Back and Re-Migrating a Limited Number of Migrations
Sometimes, we may prefer to roll back all migrations and re-migrate only a certain number of migrations. This can be done with the `migrate:refresh` command with the `–step` option.
Here’s an example of rolling back and re-migrating the last three migrations:
php artisan migrate:refresh –step=3
Creating Fresh Migrations
Furthermore, if we want to start fresh and drop all existing database tables, we can use the `migrate:fresh` command as seen here:
php artisan migrate:fresh
At the end of the day, rolling back specific migrations in Laravel is a key part of managing our database schema changes.
