  """Retrieves a list of sidebar entries for this View.

  Params usage:
    The params dictionary is passed to the getKeyFieldsPatterns
    method, see it's docstring on how it is used.
    
    django_patterns: The django_patterns value is returned directly
      if it is non-False.
    django_patterns_defaults: The dajngo_patterns_defaults value is
      used to construct the url patterns. It is expected to be a
      list of tuples. The tuples should contain an url, a module
      name, and the name of the url. The name is used as the
      page_name passed as keyword argument, but also as the name
      by which the url is known to Django internally.
    url_name: The url_name argument is passed as argument to each
      url, together with the link_id pattern, the link_id core
      pattern, and the key fields for this View.

  Args:
    params: a dict with params for this View
