how create dynamic inline keyboard markup?

[roxyash]

I'm considering a similar question (https://github.com/go-telegram-bot-api/telegram-bot-api/issues/225), but not quite putting it into practice for inline keyboard markup.

 func GenerateKeyboardWithSubjects() (tgbotapi.InlineKeyboardMarkup, error) {
    dateTo := strings.Split(time.Now().Format(time.RFC3339), "T")[0]
    dateStart := fmt.Sprintf("%v-%v-%v", strings.Split(dateTo, "-")[0], strings.Split(dateTo, "-")[1], "01")
    arg := params.GetSubjectsForAnyDateParams{
        ToDate:   dateStart,
        ToDate_2: dateTo,
    }

    subjects, err := store.GetSubjectsForAnyDate(context.Background(), arg)
    if err != nil {
        return tgbotapi.NewInlineKeyboardMarkup(), err
    }
        rows := make([][]tgbotapi.InlineKeyboardMarkup, len(subjects))
    for index, subject := range subjects {
        rows[index] = tgbotapi.NewInlineKeyboardRow(tgbotapi.NewInlineKeyboardButtonData(subject, subject))
    }
    return tgbotapi.NewInlineKeyboardMarkup(rows...), nil
}

It was easier than I thought

func GenerateKeyboardWithSubjects() (tgbotapi.InlineKeyboardMarkup, error) {
    dateTo := strings.Split(time.Now().Format(time.RFC3339), "T")[0]
    dateStart := fmt.Sprintf("%v-%v-%v", strings.Split(dateTo, "-")[0], strings.Split(dateTo, "-")[1], "01")

    arg := params.GetSubjectsForAnyDateParams{
        ToDate:   dateStart,
        ToDate_2: dateTo,
    }

    subjects, err := store.GetSubjectsForAnyDate(context.Background(), arg)
    if err != nil {
        return tgbotapi.NewInlineKeyboardMarkup(), err
    }

    rows := make([][]tgbotapi.InlineKeyboardButton, len(subjects))
    for index, subject := range subjects {
        rows[index] = tgbotapi.NewInlineKeyboardRow(tgbotapi.InlineKeyboardButton{
            Text:         subject,
            CallbackData: &subject,
        })
    }
    return tgbotapi.NewInlineKeyboardMarkup(rows...), nil
}
