A quick overview how to combine django-parler with django-oscar. This assumes you are familliar with the "Customising Oscar" topics (https://django-oscar.readthedocs.org/en/latest/topics/customisation.html). A screenshot of the integration was shown at DjangoConEU 2014 (http://django-fluent.org/blog/2014/05/lightning-talk-djangocon-eu-2014/)

{% comment %}

  This is some serious hacking to get translated fields in the Oscar template due to a lack of blocks.
  Also, currently there is no form class in django-parler so edit all translated fields in a single form,
  so the language tabs will still refresh the entire page. Improvements are welcome here.
