How to build an ordering chat bot to save multiple values for the same slot. For example: A customer can have an order like this:

  • Customer_Name: Khalid Yousif
  • Order_Date: 05-05-2021
  • Order_Items:
    •    Item_name: Milk                - Qty: 1

    •    Item_name: Chocolate      - Qty: 3 

    •    Item_name: Baby Diapers - Qty:2
  • Amount: $25.00

Another order can be like this:

  • Customer_Name: Jacob Isaq
  • Order_Date: 04-05-2021
  • Order_Items:
    •    Item_name: Juice               - Qty: 2

    •    Item_name: Bread              - Qty: 4 

    •    Item_name: Tiolette Paper - Qty: 5

    •    Item_name: Ice Cream       - Qty: 1

    •    Item_name: Tooth Paste     - Qty: 2
  • Amount: $76.00

Thank you

Hello @khalid there is Duckling which is a pre-trained model that will help you capture the amount of money each time you add it to your pipeline. check the docs Components hope this helps :slight_smile:

Thank you Amina I don’t think duckling will help in this issue. Duckling is mainly used to recognize specific type of entities. I mainly need to save multiple values of the same slot. The user will insert them using intents repeatedly.

@khalid okay what about you put the type of your slot a “list” ?

Great Every time the “shopping_items_inform” intent will be recognized, the custom action will run. Now the question is : will the list slot save the previous values every time the action will run.

I have never used a slot with the type list so I don’t have an answer but you can always try and see

if it doesn’t work try to find some examples or tag someone from the rasa staff

I hope you find a solution :slight_smile:
