How should I configure import_transform and export_transform im my configuration yaml file to be able to export and import multiple integer pr开发者_运维知识库operty?

I wrote this collection of helpers for bulk loading data:

I think that list_to_json(int) and json_to_list(int) are what you need.

Be aware that this will choke on entities that have don't have the list defined yet.
