How to extract multiple values for one slot in same intent?

rasafan · March 31, 2020, 5:40pm

Hi,

I’m trying to save multiple entities in my slot, how can I properly do this? I don’t know how many entities will a person submit since they are entering what ingredients they have currently at their disposal.

When I check my actions console the intent is recognized but my debugger prints: “Test None” so it means that he didn’t save ingredients into my slot.

**Actions.py**

class ActionRecipeSearchByIngredients(Action):

    def name(self):

        return "action_recipe_search_by_ingredients"

    def run(self, dispatcher, tracker, domain):

        ingredients = tracker.get_slot("ingredients")

        logger.debug("Test %s",ingredients)

stories.md

## story_recipe

* ask_ingredients

    - action_recipe_search_by_ingredients

    - utter_recipe

NLU.md:

## lookup: ingredients

@JiteshGaikwad I’ve seen that your Zomato chatbot does similar things, can you help maybe?

JiteshGaikwad · March 31, 2020, 5:55pm

How can help you?

rasafan · March 31, 2020, 5:56pm

Did you read my problem?

I have similar situation like you here but I would want to parse multiple cuisines for example, so someone writes: “i want indian italian and american” and I want to store all that?

## intent:changeCuisine
- change the cuisine to [indian](cuisine)
- change the cuisine to [italian](cuisine)
- change the cuisine to [american](cuisine)
- change the cuisine to [Maharashtrian](cuisine)
- change the cuisine to [south indian](cuisine)
- change the cuisine to [North Eastern](cuisine)
- can you change the cusine to [punjabi](cuisine)
- can you change the cusine to [japanese](cuisine)
- can you change the cusine to [japanese](cuisine)
- please change the cuisine to [thai](cuisine)
- please change the cuisine to [European](cuisine)
- please change the cuisine to [BBQ](cuisine)
- please change the cuisine to [Desserts](cuisine)
- please change the cuisine to [french](cuisine)
- I changed my mind I would like to try out some [chinese](cuisine) food
- I changed my mind I would like to try out some [North Eastern](cuisine) food
- I changed my mind I would like to try out some [Hyderabadi](cuisine) food
- I changed my mind I would like to try out some [Rajasthani](cuisine) food
- I changed my mind I would like to try out [Mangalorean](cuisine) food
- I changed my mind I would like to try out [Malaysian](cuisine) food
- I changed my mind I would like to try out [Bengali](cuisine) food
- I changed my mind I would like to try out [Modern Indian](cuisine) food
- can you please change the cuisine to [italian](cuisine)
- please change the cuisine to [italian](cuisine)

I’ve tried this as stories.md too but still doesn’t work:

## story_recipe{"ingredients":"berries"}

* ask_ingredients

    - slot{"ingredients":"berries"}

    - action_recipe_search_by_ingredients

    - utter_recipe

JiteshGaikwad · March 31, 2020, 6:21pm

You can use list slots to capture multiple values.

rasafan · March 31, 2020, 6:27pm

I tried with:

ingredients:
    type: list

but the same error still persists, somehow my action does not “catch” ingredients, can I do something differently in my actions.py?

class ActionRecipeSearchByIngredients(Action):

    def name(self):

        return "action_recipe_search_by_ingredients"

    def run(self, dispatcher, tracker, domain):

        ingredients = tracker.get_slot("ingredients")

        logger.debug("Test %s",ingredients)

         if ingredients:

            return [SlotSet("recipe_info", ingredients)]

        else:

            print("No recipe found.")

            return [SlotSet("recipe_info", "not found")]

JiteshGaikwad · March 31, 2020, 6:40pm

But the problem here is if user had not provided the ingredients it will take the previous ingredients value from the slot…

rasafan · March 31, 2020, 6:41pm

That is a future worry, now I send only one message when I start the bot:

“my ingredients are seed pumpkin berries”

and it doesn’t work anyway…

JiteshGaikwad · March 31, 2020, 6:45pm

Why don’t you try to set the slot by extracting the ingredients from entity and then set it into the slot.

        print()
        location=tracker.get_slot("location")

        locationEntity=next(tracker.get_latest_entity_values("location"), None)

JiteshGaikwad · March 31, 2020, 6:47pm

And I see here you haven’t written the story In which it will set the slot, due to which you are not able to get the ingredient slot in your code.

rasafan · March 31, 2020, 6:51pm

This is the error I get when I tried using get_latest_entity_values:

This are my stories.md now:

## story_recipe{"recipe_info":"berries"}

* ask_ingredients

    - action_recipe_search_by_ingredients

    - slot{"recipe_info":"berries"}

    - utter_recipe

JiteshGaikwad · March 31, 2020, 6:55pm

Can you change your story as mentioned below:

* ask_ingredients

    - action_recipe_search_by_ingredients{"recipe_info":"berries"}

    - slot{"recipe_info":"berries"}

    - utter_recipe

rasafan · March 31, 2020, 6:56pm

Let me try

JiteshGaikwad · March 31, 2020, 6:56pm

And this story will work for “recipe_info”

rasafan · March 31, 2020, 6:58pm

Yes that is my:

utter_recipe:

  - text: "The recipe is {recipe_info}."

I want to get ingredients and return new entity (recipe_info) because I will add more code in custom action.py so I will use ingredients as query params and return recipe_info.

EDIT: Same error persists: @JiteshGaikwad

JiteshGaikwad · March 31, 2020, 7:02pm

Did you tried to extract the ingredient entity using the below code:

next(tracker.get_latest_entity_values(“ingredient”), None)

rasafan · March 31, 2020, 7:07pm

When I try like that:

JiteshGaikwad · March 31, 2020, 7:08pm

Ok so that means your nlu model is not able to extract the ingredient entity value.

JiteshGaikwad · March 31, 2020, 7:09pm

Can you just check by running the below command and check whether it’s able to extract entity:

rasa shell nlu

rasafan · March 31, 2020, 7:10pm

It seems he hasn’t extracted them…

JiteshGaikwad · March 31, 2020, 7:12pm

I see here your nlu model didn’t predicted the values for ingredients entity.
