I’ve attempted to use action_back, I saw it referenced here: Default Actions
Is there a guide available on how to trigger it?
I tried just entering /back into the command line and nothing was picked up. Then I created an intent called /back, trained it, and triggered it but nothing happened there either.
Any help would be much appreciated
Is this feature still supported?
@ronankff Hi. I will suggest make an intent like go_back, and then trigger like this
go_back:
triggers: action_back
actions:
- action_backThanks for the reply @nik202, I’ll give that a shot
Hey @nik202, I set up the bot as you said. Can you confirm for me that this is the way the back function works:
Story is as follows:
@ronankff have you updated config.yml file
action_back (Default Actions)
This action undoes the last user-bot interaction. It can be triggered by the user by sending a “/back” message to the assistant if the RulePolicy is configured.
policies:
- name: "RulePolicy"
core_fallback_threshold: 0.3
core_fallback_action_name: action_default_fallback
enable_fallback_prediction: true
restrict_rules: true
check_for_contradictions: true
In your stories, you not mention action?
I guess you using Rasa 1.X ? Right? If you are using Rasa Open Source please updated to Rasa 2.7.1 or 2.6.2
I am using 1.x, apologies I forgot to even mention that.
Unfortunately we’re not in the position to upgrade versions right now. According to the Legacy docs the correct policy for this action is MappingPolicy, which I have included
Good spot with the stories file too, I changed it.
Running with the above setup gets me this error:
I’m a bit confused because as far as I can tell action_back doesn’t need to be initialised in the actions file.
did you mention this in domain.yml?
actions:
- action_back
Is your action_back is a function in action.py with trigger utterance?
An alternative solution, if you want to go back to the previous menu. In that, I can help if you want? For Rasa Ver 1.X
For example:
Bot: How are you doing? or some menu Rasa | Rasa X
User: I’m fine
Button: previous menu
User: user select previous menu
Bot: How are you doing? or some menu Rasa | Rasa X
and so on.
I am sorry, a lot have change from Rasa 1.x to Rasa 2.7.1. It’ bit confusing for me also 
But, I honestly want to assist you @ronankff
Yes, I have the action registered in the domain. My action_back is not a function in action.py yet. I thought that it would be built into Rasa as it’s a default action. Do I have to create it myself? If so, what code do I need?
Thank you for offering an alternative but I the product owner wanted something that would take you back in the conversation. For example:
Does that make sense to you?
@ronankff Yes.It fine customer is always right! Mean while if you can share your all files it will be great to test. Thanks.
@ronankff python version? can you create the requirement file for me
pip freeze > requirements.txt
Python 3.9.5
[REMOVED]
Was the original command I used to set that up.
@ronankff using rasa-x?
Hope you aware of this You can install Rasa Open Source using pip (requires Python 3.6, 3.7 or 3.8).
Its fine if your rasa x is running on python 3.9
I’m not using rasa x for this particular task. I’m just trying to make a small demonstration of the back button working and then we’ll add it to the larger project once we know it works.
@ronankff You want something like this? Sorry for late reply was busy in office work and deadlines.
OR
you want to go back to the previous step/stage every time? When you say “go back”, “back”, "put me back "
Please consider this (back option) process (dialogue conversation) based on the project. Can I ask what’s are your project objective?
I have taken this thread How to use action_back? - #9 by ronankff as a example and checked and fixed your code.
Please give me more example(as shown in above thread) so that I can help you more. Thanks.
Oh no problem man, I appreciate the help.
Ideally what they want is that the bot goes back to the previous step. That’s why I’m trying to get action_back working.
The project has a lot of conversations and sometimes people press the wrong button or whatever and want to go back and hit the right button.
@ronankff Oh my bad, I see the example and based on that trying to fix. I will see much more tomorrow. Its late now in UK. Will find solution 
Hi @nik202, any luck?
@ronankff I have seen some example, everyone using action_back function. But nothing is working as they have suggested. Do you have any links which I can see and try to fix your code.
Would you mind sharing these examples? I can try implement them myself, it’s just hard to find anything on it.
