`. Alternatively, you can also let rasa execute a custom action. You’d typically write that in python code, but of course the custom action is just some program that you write inside of your action server, which you can implement in any language you want as long as it follows the API specs.

In the document just as u represent for the loop question we can specify it in domain file as _utter\_ask\_slot name_…okay that works fine …but what I want to do is _action\_ask\_slot name_ where the question come from the custom action …but rasa jumps that part and move to the questions that come from _utter\_ask\_slot name_…have u ever tried the questions from custom action which will return action\_ask\_slot name and will be saved in action in domain file???

Yes, I just tried it and it works without problems. Did you start the action server (`rasa run actions`)? If yes, have you re-trained your model after making changes? And if yes, try running `rasa shell --debug` to get some more information.

Also, I am not sure what you mean by this. Custom actions don’t need to return anything but `[]` if you only want to send text to the user (use `dispatcher.utter_message` for this). Also, nothing is saved to the domain file while Rasa is running.

Well what I meant was for the formaction or for form filling we use _utter\_ask\_slot name \* for the bot to ask the question required to fill the form…and what I want is for the bot to ask from custom action…I know I have to put under action"action\_ask\_slot name_ in the domain file .but the bot jumps that and try to find utter\_ask\_slot name…the rasa docs doesn’t discuss much about it but it points some but didnt work for me

Rasa will prioritize the custom action, so if you have both `action_ask_x` and `utter_ask_x` for slot `x`, then Rasa will run the former. To do that, you must have implemented that custom action and given it the name `action_ask_x` via the `name` property of your custom action class in the python file. Furthermore, before you run `rasa shell`, **you have to start the action server in a separate shell** with `rasa run actions`. If the action server is not running, Rasa cannot execute the custom action and might fall back to use `utter_ask_x` instead.

For the difference between `from_text` and `from_entity`, please read [Forms](https://rasa.com/docs/rasa/forms#slot-mappings). For Rasa to catch all the entities correctly, you’ll have to provide enough training data (a dozen different examples per entity at least I’d say). If you have a fixed set of words that you always want to have recognized, you can add the `RegexEntityExtractor` to your NLU pipeline, see [NLU Training Data](https://rasa.com/docs/rasa/nlu-training-data#regular-expressions-for-entity-extraction)

Okay…but is it possible to use _DucklingEntityExtractor_ for extracting name without putting lots of examples in the nlu data

Yes. If duckling provides an extractor for names. See [Tuning Your NLU Model](https://rasa.com/docs/rasa/tuning-your-model#entity-extraction)
