Plopulate slot within form actions

Hi ,

I have different leave type which are captured by NLU, Now I want to create form actions for which i want to map the leave_type with leave_type_ID as below . I have created a slot for it , But as there are 3 parts in form actions 1] required_slots, 2] slot_mappings , 3] validate_cuisine. I am not sure on how to do this.

I am trying to do the below in def validate_leave_type . I am not sure is it right i wan leave_type_id to run a wsdl service

        leave_type_maping ={

 leave_type_id = leave_type_maping[value]

Also if the above is need to be done in slot_mappings please share the code on how to do

Thank you Aashay
