That's an implicit relative import. From
https://www.python.org/dev/peps/pep-0008/:
So please:

  from cms.utils import get_page_params

[kzar, 2015/04/07 14:43:56]

Done.

[Wladimir Palant, 2015/04/06 19:14:30]

We never specify the format as part of the page. You should "guess" the format:

  source = self._params["source]
  for format in converters.iterkeys():
    if source.has_page(source, format):
      ...

In fact, that's something that get_page_params() could do.

[kzar, 2015/04/07 14:43:56]

Done.
