In my ‘action\_ask\_weather’ action class, the ‘run’ method returns: `return [Restarted()]` By doing this, I want to be able to have the effect of having only single-turn dialog, that is. the bot only supports a single Question-Answer pair between user and the robot. Once the answer is generated through the action class, I thought I should return a list of Restarted() to destroy any previous dialog history. However, when I test, this return value doesn’t have any effect, and when I debug into the code in processor.py, the history is still remembered well, including the events and slots. Should I do something else, in addition to the returned value to achieve the effect? ---

restarted doesn’t erase all previous events. It is taken into account when creating `applied_events()` for featurization, so that policies ignore all previous history. So effectively you remove all history, so it’s still work ---

@Ghostvv, hi Ghostvv, didn’t quite get what you mean. Can you elaborate on it a little more? Thanks ---

`tracker.events` are not used entirely for featurization. For featurization we use [tracker.applied\_events()](https://github.com/RasaHQ/rasa/blob/e002d095134d52afbd4474a77738739957263db6/rasa/core/trackers.py#L335) which doesn’t include any history before `Restarted()` ---

@Ghostvv, So, do you have a recommendation on how to achieve a single-turn dialog robot? By that, simply remove all previous events at some point? Is there a way to do that? ---

“So effectively you remove all history, so it’s still work” @Ghostvv Do you mean Restarted() has the effect of removing history? But my test didn’t feel that. Is that true? ---

yes `Restarted()` do the job, in your test you checked different thing ---

@Ghostvv This actually works and thanks!
