php - 如何在 Laravel 中进行条件数据库播种？

Question

我可以创建种子组吗？例如，我有一些我只想在某些时候执行的种子。执行时如何添加标志php artisan migrate --seed --group1

我对此类功能有哪些选择？

Answer 1

Well, what you could do is create multiple Seeder extended classes, and having each one of them running $this->call() on a specific group of tables and then specify which one you want using the --class flag. Something like this:

class GroupOneDatabaseSeeder extends Seeder {

    public function run() {
        Eloquent::unguard();

        $this->call('UserTableSeeder');
        $this->call('RoleTableSeeder');
    }

}

And then call it this way:

php artisan db:seed --class="GroupOneDatabaseSeeder"

Well, that or you could extend the SeedCommand to add this functionality via methods instead of classes.
