In Laravel, seeder are used to populate the database with initial or dummy data. They provide a convenient way to create and insert data into database tables. Here's a step-by-step guide on using seeder in Laravel:
Create a Seeder
To create a new seeder, you can use the make:seeder
Artisan command. For example, to create a seeder for the "users" table, run the following command:
Define Data
Open the generated seeder file in the database/seeders
directory. In the run
method, you can define the data that you want to seed into the database. You can use Laravel's query builder or Eloquent ORM to insert the data.
Run the Seeder
To execute the seeder and insert the data into the database, use the db:seed
Artisan command. By default, all seeder will be run. If you want to run a specific seeder, you can use the --class
option.
Seeder and Rollback
Seeder can be rolled back just like migrations. To undo the last batch of seeder, you can use the db:seed --class
command with the --reverse
option.
Using seeder in Laravel makes it easy to populate the database with initial data or create dummy data for testing purposes. It allows you to quickly insert data into tables without manual intervention.
