The one that is inherited from my common base class (I followed the tutorial
[1] except that I don't
have separate manager classes) through init_db.

Is it ok then to just define init_db once in the base class and never add a
'db' parameter in special
purpose methods? I thought if no 'db' is given, the one from init_db is used in
every search.
Or is this a new one on every call so that I don't have the needed same db for
all the work?
