ahlib-db's Issues

Change OrderByFunc signature to builtin type

func OrderByFunc(p xproperty.PropertyDict) func(source string) string

// PropertyMapperValue represents a value stored in PropertyMapper, used to represents some property settings.
type PropertyMapperValue struct {
	// id represents the property order `id`.
	id int

	// revert represents if need `revert` in sort for destination.
	revert bool

	// arg represents some other arguments for property.
	arg interface{}

	// destinations represents the destination properties.
	destinations []string
}

// GetId returns the id in PropertyMapperValue.
func (p *PropertyMapperValue) GetId() int {
	return p.id
}

// GetRevert returns the revert in PropertyMapperValue.
func (p *PropertyMapperValue) GetRevert() bool {
	return p.revert
}

// GetArg returns the arg in PropertyMapperValue.
func (p *PropertyMapperValue) GetArg() interface{} {
	return p.arg
}

// GetDestinations returns the destinations in PropertyMapperValue.
func (p *PropertyMapperValue) GetDestinations() []string {
	return p.destinations
}

Return err when Duplicate

// CreateErr checks gorm.DB's create result.
func CreateErr(rdb *gorm.DB) (xstatus.DbStatus, error) {
	if IsMySQL(rdb) && IsMySQLDuplicateEntryError(rdb.Error) {
		return xstatus.DbExisted, nil // <<< rdb.Error
	} else if rdb.Error != nil || rdb.RowsAffected == 0 {
		return xstatus.DbFailed, rdb.Error
	}

	return xstatus.DbSuccess, nil
}

go-redis logger

Change gomodule/redigo to go-redis/redis, and use hook to add logger.

Notice that the value field is a private field in xxxCmd struct, need to use reflect to get it.

type hook struct{}

func (h hook) BeforeProcess(ctx context.Context, _ redis.Cmder) (context.Context, error) {
	return ctx, nil
}

func (h hook) AfterProcess(_ context.Context, cmd redis.Cmder) error {
	log.Println("=====================================")
	log.Println(cmd.String())
	log.Println(cmd.Name(), cmd.Args(), cmd.Err())
	log.Println("=====================================")
	return nil
}

func (h hook) BeforeProcessPipeline(ctx context.Context, _ []redis.Cmder) (context.Context, error) {
	return ctx, nil
}

func (h hook) AfterProcessPipeline(context.Context, []redis.Cmder) error {
	return nil
}

Refactor the whole library to v1.5

Progress:

• xgorm
• xneo4j
• xredis
