code: def path(self, which=None):
          
          if which in ('compare',):
              return '{0}/{1}'.format(super(Errata, self).path('base'), which)
          return super(Errata, self).path(which)
docs: Extend ``nailgun.entity_mixins.Entity.path``.
  
          The format of the returned path depends on the value of ``which``:
  
          compare
              /katello/api/errata/compare
  
          Otherwise, call ``super``.
