django-parler - DjangoCon EU 2014 lightning talk

Extended version of my previous django-parler presentation. Explain why django-modeltranslation or django-hvad were nog used, and what complex inheritance I'd faced. Now features such as:

* Python 3 support
* Prefetching translations
* Caching
* High-level features such as `{% get_translated_url %}`.
* Admin inlines

  2. Simple Django model translations without nasty hacks with nice admin

    integration.
  3. Got hopeful Making a CMS multilingual: Well, let's use something

    existing...
  4. django-modeltranslation :-(

  5. django-hvad :-( Very nice admin, awesome API – however: Overrides

    just about all ORM methods! Lots of metaclass magic Mixing translated with untranslated objects = hard Can't be combined with other apps (mptt, polymorphic, shop) Doesn't call super() often
  6. django-polymorphic-tree Yes, we do crazy things...

  7. django-fluent CMS ...when they make sense

  8. 1 row for each language

  9. Let's just do this..!

  10. And tried more hacking!

  11. Package that! So we: – Hacked something directly in the

    CMS app – K.I.S.S – Manually created translated fields table – Manually assigned descriptors – Hey that works!!
  12. Model API

  13. Usage
