group in user.groups

for group in user.groups:
     if permission in group.permissions:
         return True

But the last one is IMO better solved in a higher authority layer, so 
that you can abstract thinks like

if identity.is_anonymous:
     groups = [Group.query().get_by(group_name='anonymous').one()]
else:
     groups = identity.groups + \
       [Group.query().get_by(group_name='authenticated').one()]

for group in groups:
     if permission in group.permissions:
         return True

Also:

Group.users
Group.by_group_name()           #*
Permission.by_permission_name() #*

* Should we also provide User.by_name(), Group.by_name() and 
Permission.by_name() as aliases?
