Question about populating custom field

[jmricker]

I'm working on a metadata source plugin that fetches Dewey Decimal and Library of Congress data. That part of it is working fine -- when it finds a piece of information, it stores it as an identifier. What I'm trying to do next is calculate a genre to plug into a custom column.

Ive got something like this so far:

mi = Metadata(title, authors)
mi.identifiers = identifiers

mi.set('#genre','im a test')
self.clean_downloaded_metadata(mi)
result_queue.put(mi)

But genre doesn't seem to get populated. Similar results with the .set_userdata method. Whats a better way to do this?

Thanks!

@jmricker - basically you can't.

See this thread in the development forums for the discussion about it.

All you can do right now is put it into one of the existing fields that Calibre does support, like tags or comments.

Phew. So its not just me I've looked through the api swearing I'm doing it right. Thanks for the pointer.

Now since identifier is populated with my two values, I guess I can build a custom template for a column and display the genre that way. (I think, haven't tried this yet).

Are you still working on this plugin, and if so, how much of it works? I'm willing to help beta test it, if you need somebodyw illing to risk their collection to see how well it works.

Asking, because I'd love to have both Dewey Decimal and Library of Congress Catalog numbers in my Calibre Library. What I'd really love, is a plugin that automatically adds complete CIP data for every book.
