问题
My bot processes incoming user messages and takes action based on the intent. For simple, one shot answers that do not require multiple passes between users and the bot, it works well. Now when I want to implement a dialog, it's getting tough. Once the user sends the message and the Dialog gets triggered, the bot asks the user for input. Once the user provides the input, this input is being again processed by LUIS to understand the intent. However, I do not want this to happen as this abandons the ongoing Dialog.
I want to understand if there some way I can detect if a Dialog is under progress and what dialog is it. If I can know this, I can skip the LUIS intent check part and direct the logic to Dialog. I've used the Multi-turn Prompt as a basis for this. Below is what I expect.

This is in a way related to this question and though there was a discussion on Github here, I think my question/requirement is in a way different. I tried to understand if there's a way to get the current active dialog in other SDK but couldn't find any useful information.
The author of the above question has answered his approach. Though it's a good one, it only partially suits my requirements. The answer is useful when there are small number of intents and also where only Luis is used. My use cases has more than 50 intents and the list will keep increasing. I'll need to keep adding dialogs inside the maindialog. If I'm able to identify the active dialog, I'll be able to dynamically call the run_dialog method.
Also, I use QnA Maker to answer the user when the intent of the user input is None. When I tried to implement the QnA Maker also into a dialog, I'm ending up with certain errors below.

Error in case of None intent and Q&A Maker processes the user question. Also I've not tried the QnA Dialogs yet to see if they work in this setup.
It would be great if we could somehow access the current active dialog id so that we can switch the dialog easily based on the id by creating a map of intent to dialog.
Thanks to the author of this question for sharing his solution.

Whenever an intent and there by child intent is detected from Dispatch App, the dialog is getting triggered. However, as soon as the user provides input to the question from first dialog, which results in a None intent, the conversation ends with Dispatch unrecognized intent: None. The dialog is not supposed to end until an end_dialog is called. I tried doing the same by passing the child dialog into a Main Dialog like above, but it also results in the same. What should I be doing in order to skip the intent check or what am I doing wrong here ?
回答1:
Finally, I'm able to do exactly what I want. The Python SDK and the community around is not as mature as the .net one which is why it took a lot more time than it actually should. I followed a .Net sample on YouTube Github Repo. Checking if a dialog is active or seemed so straightforward after watching this sample. Below is the Python implementation. What the below code does is that, it creates a DialogSet when the bot is initiated and then a DialogContext. It checks if there is any existing dialog that can be run in the on_message_activity method, which if true, continues the old dialog or else, sends the message to LuisHelper Class to detect the intent and initiate the dialog based on intent.
