Fixed #18169 -- NoReverseMatch not silenced if from block.super

    pass

class NoReverseMatch(Exception):

    # Don't make this raise an error when used in a template.

    silent_variable_failure = True

    pass

def get_callable(lookup_view, can_fail=False):

    """

  stored as ``null``. Previously, storing a ``blank`` value in a field which

  did not allow ``null`` would cause a database exception at runtime.

* If a :class:`~django.core.urlresolvers.NoReverseMatch` exception is risen

  from a method when rendering a template it is not silenced. For example

  {{ obj.view_href }} will cause template rendering to fail if view_href()

  raises NoReverseMatch. There is no change to {% url %} tag, it causes

  template rendering to fail like always when NoReverseMatch is risen.

Features deprecated in 1.6
