问题描述
我有以下故事：
story: survey continue
steps:
- intent: greet
- action: utter_greet
- intent: affirm
- action: health_form
- active_loop: health_form
- intent: out_of_scope
- action: utter_ask_continue
- intent: affirm
- action: health_form
- active_loop: null
- action: utter_slots_values
让我们假设以下对话：
1 Me: hello
2 Bot: Hi! It's time for your daily wellness check. Tracking healthy habits is a great way to measure your progress over time. Would you like to answer a few questions about your health?
3 Me: yes please
4 Bot: Did you exercise yesterday? Don't sweat it if you didn't run a marathon - walks count!
5 Me: wait stop
6 Bot: Sorry,I don't quite understand. Do you want to continue?
7 Me: actually yes
8 Bot: What kind of exercise did you do?
如您所见，在第 7 条消息中，如果用户做出肯定意图，它会回答第 6 条消息中提出的问题以及第 4 条消息中提出的问题。
我希望对话流程是这样的：
[...]
6 Bot: Sorry,I don't quite understand. Do you want to continue?
7 Me: actually yes
8 Bot: Did you exercise yesterday? Don't sweat it if you didn't run a marathon - walks count!
这是预期的行为吗？我怎样才能达到我心目中的预期流量？
解决方案
在 actions.py 中，向那些修改机器人内存的 extract_<slot_name> 函数添加更严格的条件，其意图与回答 utter_ask_continue 问题的意图相同。
if (not tracker.slots.get('requested_slot') == "confirm_exercise" or tracker.get_last_event_for(event_type="action",exclude=["health_form"],skip=1)['name'] == "utter_ask_continue"):
return {}

解决方法
尝试将您的表单设置为在 active_loop 下再次运行，而不是 null。来自 Rasa 官网的示例故事，关于如何在另一个 Intent 之后“返回”表单 here
rules:
- rule: Example of an unhappy path
condition:
# Condition that form is active.
- active_loop: restaurant_form
steps:
# This unhappy path handles the case of an intent `chitchat`.
- intent: chitchat
- action: utter_chitchat
# Return to form after handling the `chitchat` intent
- action: restaurant_form
- active_loop: restaurant_form
