Return to a previous conversation state after a already handled update message being edited #5111

I have a bot that collects some user input and save it to the database. Each state deals with non-edited messages only and perform user input validation. I want to allow the user to edit a previously sent information so she/he can make corrections to the input. To do that, I keep a map relating message_id to the state that handle it. The callback that deal with edited messages, located in the fallbacks sections, retrieves this mapping, put the update back in the queue and set the appropriate conversation state but I don't know how to force the conversation handler to be executed again and to process the edited message in its appropriate state.

text_not_command_or_end_filter = filters.TEXT & ~(filters.COMMAND | filters.UpdateType.EDITED_MESSAGE | filters.Regex("(?i)^FIM$"))

expense_conv = ConversationHandler(
        entry_points=[ CommandHandler("nova_despesa", start_new_expense) ],
        states={
            COMPANY:            [MessageHandler(text_not_command_or_end_filter, company)],
            PERIOD:             [MessageHandler(text_not_command_or_end_filter, period)],
            COST:               [MessageHandler(text_not_command_or_end_filter, cost)],
            PAYMENT_TYPE:       [MessageHandler(text_not_command_or_end_filter, payment_type)],
            ...
            ConversationHandler.TIMEOUT: [MessageHandler(filters.ALL, done)],
        },
        fallbacks=[
            MessageHandler(filters.UpdateType.EDITED_MESSAGE, handle_edited_message),
            MessageHandler(filters.ALL, done)
        ],
    )

async def handle_edited_message(update: Update, context: ContextTypes.DEFAULT_TYPE) -> int:
    msg_id = update.edited_message.message_id
    state = context.bot_data["message_map"][msg_id]
    await context.application.update_queue.put(update)
    return state

Any guidance on this?

Thanks all.

Hmm your setup should work generally, in that PTB already updates conversation's state when/if returned from a fallback, no need to force it :)

However the issue seems that your text_not_command_or_end_filter filter excludes filters.UpdateType.EDITED_MESSAGE and hence edited messages will not be handled by state handlers.

You are right. I've put the app in an infinite loop. Is it possible to create a copy of the update object with the edited message and convert it to a regular message? This way, when I put the copy back in the queue, it will be handled by the appropriate callback.

If you want to, yes there is an internal context manager for all Telegram Objects (e.g Update) called _unfrozen() that can be used to update attributes of instances.

However just note that this is a private method not intended for public use.

An alternative would be to use filters.MESSAGES and have a stricter text filter for each state handler to differentiate it from others.
