// 1.定义接口
type IClubs interface {
	GetClubs(ctx context.Context) (clubs []entity.GoClubs, err error)
	GetClubShows(ctx context.Context) (shows []entity.GoShows, err error)

	EditClub(ctx context.Context, club do.GoClubs) (err error)
	DeleteClub(ctx context.Context) (err error)
}

// 2.定义接口变量
var localClub IClubs

// 3.定义获取接口实例的函数
func GetClubs() IClubs {
	if localClub == nil {
		panic("IClubs接口未实现或未注册")
	} else {
		return localClub

	}
}

// 4.定义一个接口实现的注册方法
func RegisterClubs(club IClubs) {
	localClub = club
