Refresh document on API

[Nguyen Do Le Bao]

Haha this may sound very ridiculous but will it possible to refresh document in API... 

This is because the API (AFAIK processed by worker) and the web front end (by web process) can open the same document. 

If this happens, on the Web, it's fairly simple to resolve -> just clear cache and reload. 

But on API, this can be troublesome :|. How do I avoid this, or resolve this for API so that at least it catch this error, refresh and try again ?

Thanks a lot!!!

If you try to update a document that does not have the latest timestamp, it will give you an exception. You just need to catch it

Thanks a lot!!!

Okay, 

Figured out what's wrong in the code. In server, gotta call frappe.get_doc(Doctype, DocName) to refresh it

Thank you!
