Rasa Regex string

Hi,

I am working on a chatbot which searches for a product in my db. I am facing a couple of issues:

  1. The object_name is not identified at all no matter how many data sentences i provide. Instead of providing a lookup is there a better solution for identifying name as an entity and store it in the slot?

  2. I need to query the id, in which case the id can be anything like: numeric or something like 393* or 393? or 3?3 (regex format). i need to store this in my slot. The slot type given is text.

I provided around 30-40 sentences as examples

My regex is given as :

regex:item_id

  • [0-9][?]{0,1}[0-9]{0,}

please provide help on this soon.

Training data(nlu.md):

intent: itemidsearch

I am facing the same issue. Regex entities are not being identified.

Any improvements here? How did you guys manage to get it working?

I don’t understand what is the actual problem

@Ghostvv I think he want to pass item_id as something like a parameter to his story for querying db in the backend.
use ActionForm and configure slot_mappings and write a custom_validation for slot could help…

just remember set return to self.from_text(intent = None) could help…

def slot_mappings(self): 
    return { "name": self.from_text(intent=None)}

@manpreetkaurm There is a nice blog from Justina Petraityte about this topic. hope this can help you.
