海外TECH DEV Community Adding and Removing columns from existing tables using Laravel migrations. https://dev.to/roxie/adding-and-removing-columns-from-existing-tables-using-laravel-migrations-389g Adding and Removing columns from existing tables using Laravel migrations TeaserHave you been at that point where you finished setting up your database and realized you forgot to add a column or you put in a wrong column and you have to remove it Are you like me that usually refreshes the entire database for minor changes That s poor programming practice and what would you do if it was a company s database Nevertheless I discovered an easy way out so please enjoy the read IntroductionLaravel migrations simply allows you to easily perform certain actions to the database without going to the database manager eg phpMyAdmin They can also serve as a version control for your database A default laravel migration file comes with a class definition containing both an up and a down method The up method is run when migration executes to apply changes to the database while the down method is run to revert those changes Generating MigrationsA migration can be simply generated with the following command P S Migration files are in the database migrations directory The name of the table to be created is tests you can change it to any preferred name php artisan make migration create tests table Laravel will use the name of the migration to attempt to guess the name of the table and whether or not the migration will be creating a new table If Laravel is able to determine the table name from the migration name Laravel will pre fill the generated migration file with the specified table The migration file should look like this by default use Illuminate Database Migrations Migration use Illuminate Database Schema Blueprint use Illuminate Support Facades Schema class CreateTestsTable extends Migration Run the migrations return void public function up Schema create tests function Blueprint table table gt id table gt timestamps Reverse the migrations return void public function down Schema dropIfExists tests P S Schema create is only used when a table is to be created initially A common error is trying to use it to add a column to an existing table The tests table that should have two columns name string and age integer will be written in the up method as follows public function up Schema create tests function Blueprint table table gt id table gt string name table gt integer age table gt timestamps Running MigrationsTo execute migrations to the database run this Artisan command php artisan migrateThis command runs all outstanding migrations P S Confirm the database that it s been updated with the columns and their respective types Other Migration Commandsphp artisan migrate rollback This rolls back the last batch of migrations php artisan migrate reset This rolls back all your applications migrations php artisan migrate refresh This rolls back all your migrations and execute the migrate command Its like recreating your entire database php artisan migrate fresh This drops all the tables and executes the migrate command again P S The rollback always executes the corresponding down method Updating Tables Adding columns to an existing table A gender string column is added to the tests table by the following steps Create a migration filephp artisan make migration add gender to tests table table testsUsing Schema table in the up method which will be provided by default columns can be added as follows public function up Schema table tests function Blueprint table table gt string gender Setting up the rollback optionThe down method should also be updated because of rollbacks public function down Schema table tests function Blueprint table table gt dropColumn gender Now execute the migrations To run the migrations use this Artisan command php artisan migrate P S Confirm that the gender column has been added to the tests table on your database Note Laravel places the added column last on the table however it can be placed at any desired position on the table For the gender to be placed after the name the up method would rather be like this public function up Schema table tests function Blueprint table table gt string gender gt after name This looks more organized and better The gender column is successfully added to the tests table Updating Tables Removing columns from an existing table There are several ways to remove a column from a table Remove a columnTo remove the name column from tests table Create the migration file with this Artisan command php artisan make migration drop gender from tests table table testsUpdate the up method with column you want to drop public function up Schema table tests function Blueprint table table gt dropColumn name Run migrationsExecute the migrations with this Artisan command php artisan migrateP S Confirm that the name column has been dropped on the tests table P S A migrations file name is unique so every migration file should have different names when creating them Remove multiple columnsIn order to remove more than one column from your table the same steps are followed as above but the up method is slightly different The column names are passed into an array as a single argument to dropColumn like this public function up Schema table tests function Blueprint table table gt dropColumn age gender Here are the results on the database Remove a column if it exists As usual follow the same guides as outlined in the first method of removing column with the only slight difference in the up method However the column will be checked if its existing before its dropped The up method will be as follows public function up Schema table tests function Blueprint table If the id column exists on tests table if Schema hasColumn tests id drop the id column Schema table tests function Blueprint table table gt dropColumn id After running the migrations here is the final output of our database The id name age and gender column is successfully removed from the table ConclusionNow you don t need to refresh your database always for these minor changesThis entire code is open source on Github Thank you for reading 2021-06-06 22:35:54
