  # We have to workaround a bug in Rails 3 here. But, since Rails 3 is no longer fully supported,
  # this is not going to be fixed.

  # https://github.com/rails/rails/issues/7618
  #
  # With our workaround, the `delete_cache` method is called on the `DagLink` when
  # `group.members.destroy(user)` is called.
