在GORM中首次迁移时插入种子数据

package migrations

import (
    "github.com/jinzhu/gorm"
    "github.com/your/package/models"
)

    migrations := []func(*gorm.DB) error{
        createUsersTable,
        insertSeedData,
    }

    // Apply migrations
    for _, migration := range migrations {
        err := migration(models.DB)
        if err != nil {
            panic(err)
        }
    }
}

    err := db.AutoMigrate(&models.User{}).Error
    if err != nil {
        return err
    }

    return nil
}
