Before & After

Manual Approach (3+ hours per table) 

// Write by hand for every table...
type User struct {
    ID        int       `json:"id" gorm:"primaryKey"`
    Email     string    `json:"email" gorm:"unique;not null"`
    CreatedAt time.Time `json:"created_at"`
    UpdatedAt time.Time `json:"updated_at"`
}

func GetUsers(c *gin.Context) {
    // 50+ lines of boilerplate CRUD...
}
