If i want to get total count of specific record from database, how can i achieve it using the experimental feature knowledge base actions?
We don’t support aggregate functions out of the box. You would need to overwrite the ActionQueryKnowledgeBase (see Knowledge Base Actions and link to the current cod: rasa-sdk/actions.py at master · RasaHQ/rasa-sdk · GitHub).
Do you want to always aggregate stuff when querying the knowledge base or just sometimes? If it depends on the user request, you might want to add a new function to the action, such as _query_aggregate. You would need to overwrite the run method (rasa-sdk/actions.py at master · RasaHQ/rasa-sdk · GitHub) and route to the method whenever the user request matches certain circumstances.
Hope that helps. Let me know if you have any further questions.
