Prompt stage validation

Further validation of prompts can be done using policies.

To validate that two password fields are identical, create the following expression policy:

if request.context.get('prompt_data').get('password') == request.context.get('prompt_data').get('password_repeat'):

return True

ak_message("Passwords don't match.")

return False

This policy expects you to have two password fields with field_key set to password and password_repeat.

Afterwards, bind this policy to the prompt stage you want to validate.
