However it doesn’t handle the re-import of lists by default (it just treats them as strings). You can add an inline lambda function to the .yaml file to fix this. This handles lists of strings, but it can probably be modified to handle other types.

- property: mylist
external_name: mylist
import_transform: “lambda x: len(x) > 0 and eval(x) or ””

Why it works:
In your csv, your list should export like so:
“[u'item1', u'item2', u'item3']“
Running an eval on this string, converts it to a list. The length check is like if/else statement, if len(x) > 0 convert it else use empty string.

Try it out!

http://shoppertalk.appspot.com

It’s unbreakable. Ok, that’s not true, but I do need some testers.

It’s a Django app running on Google App Engine. It utilizes the Twitter api and their OAuth implementation (so you can log in with your Twitter account).

Currently only the Amazon product catalog is available for browsing, but more will be added.
