Laravel 4 db seed specific seeder file
提问by user1995781
I have an existing user table with information seeded via db:seedfrom UserSeeder.php. Now, I am adding new product table and want to seed information into product table. How can I prevent Laravel from seeding the UserSeeder into the database, but only the new ProductSeeder being seeded?
我有一个现有的用户表,其中包含通过db:seedUserSeeder.php播种的信息。现在,我正在添加新的产品表并希望将信息播种到产品表中。如何防止 Laravel 将 UserSeeder 播种到数据库中,但只播种新的 ProductSeeder?
Thanks.
谢谢。

You can call individual seed classes by their class name. From the docs.
您可以按类名调用单个种子类。从文档。
By default, the db:seed command runs the DatabaseSeeder class, which may be used to call other seed classes. However, you may use the --class option to specify a specific seeder class to run individually:
默认情况下,db:seed 命令运行 DatabaseSeeder 类,该类可用于调用其他种子类。但是,您可以使用 --class 选项指定要单独运行的特定播种机类:
php artisan db:seed --class=ProductTableSeeder
In the example above, the ProductTableSeederclass should exist in database/seeds.
在上面的例子中,ProductTableSeeder类应该存在于database/seeds.

Here's a working example with the class full namespace:
这是一个具有完整命名空间的类的工作示例:
Should use double backslashes \\.
应该使用双反斜杠\\。
Class name is DefaultBannersSeeder.
班级名称是DefaultBannersSeeder.
php artisan db:seed --class=App\Containers\Banners\Data\Seeders\DefaultBannersSeeder
