Hi all, I've asked this question on stackoverflow (http://stackoverflow.com/questions/18913661/using-django-relatedfield-for-custom-join-queries), but figured it might be better to post it here:
I'm curious whether a RelatedField can be used to cause custom join queries. I would like to apply this in django-parler (https://github.com/edoburu/django-parler), a multilingual app for Django. For example, when "slug" is a translated field, I would like to have: MyModel.objects.filter(slug="foo") to operate as: MyModel.objects.fiter(translations__slug="foo") under the hood. This is possible with the API of the RelatedField class for example? I noticed there are several API hooks in the RelatedField class, such as m2m_reverse_field_name(), m2m_target_field_name(), m2m_column_name(), extra_filters() etc.. which are used in the GenericRelation and django-taggit's TaggableManager classes but I have no idea how these work. N.B. Regular field access on instances is covered in django-parler (using descriptors that proxy to calls to the translated table), and I would love to extend support to ORM queries as well.
