Im sending Inline Keyboards for different commands with the tgbotapi.NewInlineKeyboardButtonData function. How do I distinguish from which command the callback data comes from while handling the callback?
The only method I can think of is to prefix the InlineKeyboardButtonData with something like the command name and match this in the callback handler. But is there a more elegant solution? E.g. something that comes near to a conversation-based flow?
My example code (simplified)
#### main.go
```go
// ...
func main() {
// ...
for update := range updates {
if update.CallbackQuery != nil {
handleCallbackQuery(bot, update)
continue
}
if update.Message != nil && update.Message.IsCommand() {
handleCommand(bot, update)
continue
}
}
}
func handleCallbackQuery(bot *tgbotapi.BotAPI, update tgbotapi.Update) {
// How to distinguish if the callback data comes from command "addX" or "addY"???
}
func handleCommand(bot *tgbotapi.BotAPI, update tgbotapi.Update) {
msg := tgbotapi.NewMessage(update.Message.Chat.ID, "")
msg.ParseMode = tgbotapi.ModeMarkdown
switch update.Message.Command() {
case "addX":
users := getUsers() // []string with usernames
msg.Text = "For which user do you want to add X?"
msg.ReplyMarkup = makeUsernameKeyboard(users...) // see bot_keyboards.go
case "addY":
users := getUsers() // []string with usernames
msg.Text = "For which user do you want to add Y?"
msg.ReplyMarkup = makeUsernameKeyboard(users...) // see bot_keyboards.go
}
bot.Send(msg)
}
```
#### bot_keyboards.go
```go
// ...
// makeUsernameKeyboard creates an InlineKeyboardMarkup that can be directly
// assigned to msg.ReplyMarkup. Every User is listed in its own line.
func makeUsernameKeyboard(usernames ...string) tgbotapi.InlineKeyboardMarkup {
rows := make([][]tgbotapi.InlineKeyboardButton, 0)
for _, username := range usernames {
rows = append(rows,
tgbotapi.NewInlineKeyboardRow(
tgbotapi.NewInlineKeyboardButtonData("@"+username, username),
),
)
}
return tgbotapi.NewInlineKeyboardMarkup(rows...)
}
```
