Django-oscar: Translatable models

[maikhoepfel]

Currently, several parts of Oscar are not supporting switching languages on-the-fly. Categories are one example. Review is needed to find good solutions to that problem.

@codeinthehole @maikhoepfel what do you think about using https://github.com/deschler/django-modeltranslation?

I'm thinking about integrating django-modeltranslation. What do you think @solarissmoke @mvantellingen ?

[solarissmoke]

Ok with me, but it would be nice if we could somehow make the dependency optional. Not sure whether that is possible.

I'm not sure if we should use https://github.com/deschler/django-modeltranslation or https://github.com/django-parler/django-parler.
To me django-parler looks like the right approach after reading https://django-parler.readthedocs.io/en/latest/background.html#database-schema, but django-modeltranslation seems to be easier to implement. Could you chime in, @vdboor?

I think having out-of-the-box support for django-modeltranslation would solve the problems for anybody who needs two or three languages. The database model isn't as clean as on django-parler but it's much more straightforward to work with.

Currently a bunch of the dashboard views need to be overriden to make django-modeltranslation to work.

This was discussed on the mailing list a few years back, but modeltranslation for sure.

I think we should use django-parler, because it adds the possibility to add languages without the need to create a migration. With django-modeltranslation you have to use a migration, everytime you decide to add a language. django-parler adds the possibility to give administrative users using the dashboard more power. It gives us flexibility. If an admin decides to add a language, we could make it possible that they could translate categories, emails, etc. to this language immediately.

(django-parler maintainer here) I've managed to include parler in an oscar website. A somewhat rough implementation is: https://gist.github.com/vdboor/46348490c7cd1a5b08f4 This doesn't properly support tab-switching (entering a new language means saving the existing first), but everything else worked with the translated fields. This implementation keeps the old title and description fields but leaves them alone.
