- middleware i18n url
- 5 (after 5 ratings)
This is an example middleware that is highly inspired by how Symfony handles i18n in URLs. You basically set a (?P<dj_culture>[\w-]+) pattern in your URL and this middleware will determine the language to use for the i18n toolkit for Django.
It also removes the dj_culture parameter after dealing with it, so that you don't have to change all the views you want this middleware to work with.
