GUI plugin.

Having trouble getting the parameters right for the add_books() method (database2.py). I'm using advice from an older post to the effect of:

Code:

gui = get_gui()
db = gui.library_view.model().db
db.add_books(...)

I have a file object (PersistentTemporaryFile) representing a valid ePub called "result"

I have a metadata object ('mi'); retrieved using

Code:

mi = get_metadata(result, 'epub')

I'm able to successfully use 'import_book' to add the book:

Code:

db.import_book(mi, [result.name])

with all the correct metadata, so I'm assuming my get_metadata call is working(?), but I can't seem to get the add_books() call to work without the following error:

Spoiler:

I can't seem to nail down what is needed in the 'paths' and 'formats' parameters of the add_book() method.

Can someone clue me in to how to pass the correct parameters to the add_books method (based on my file object and my metadata object)?

I'm wanting to use the "add_books" method instead of "import_book" simply because it has the "add_duplicates" flag that I'm assuming that I can set to false in order to prevent adding a duplicate book (or at least honor the library settings for dealing with duplicates). If there's a better way to achieve that, I'm all ears, too.

Thanks in advance
