Maybe somebody can explain or just show example how i can update Meta data in database from Plugin?
I create Plugin to update Metadata when i convert from fb2 to EPUB, works fine, but change Meta only in EPUB file, but i need change in DB also.
Or maybe how to make some bath proccess of "Take meta data from *** format", like now exist in Metadata edit GUI?
Thank for advice.
P.S. I am new in Pithon
