I used to (at least with the 0.9 tree) be able to access metadata and series information for a book with "self.metadata" and "self.series".
With the switch to db/backend.py, I can't find those methods anymore:
Code:
calibre, version 1.5.0
...
ERROR: Unhandled exception: <b>AttributeError</b>:'DB' object has no attribute 'series'
What is the current best practice to access this information?
