cannot normally specify a partial index on an abstract base class, since
the :attr:`Meta.indexes <django.db.models.Options.indexes>` option is

(including ``name``) each time. To work around name collisions, part of the
name may contain ``'%(app_label)s'`` and ``'%(class)s'``, which are
replaced, respectively, by the lowercased app label and class name of the

name='%(app_label)s_%(class)s_title_index')``.
