I am developing a website using Django Mezzanine.
I have some pages using a model derived from Mezzanine Page model with translatable fields (using i18n) and this works.
However I have some pages relative to some events in given countries, so they are only in one language, and they use a model derived from Mezzanine Displayable model, without translatable fields but a language attribute.
In the list I tried to put links including the language of the page (like /en/events/event/eventslug ).
I tried to add translation.activate(lang_code) to the view.
This way I get the page in the wanted language (I use {% trans %} template tags).
The problem comes when I visit the page from another language (for example if I am on the filter page in Spanish and go to an English event). Then the language switch (mezzanine form sending a POST request to /i18n/) doesn't work any more (I am locked in English) The switch still work in private navigation for example as long as I don't visit one of this pages from another language.
How can I fix this? I am out of ideas as of why...
Update: I changed the urlpattern so it is not i18n anymore (I think it makes more sense) but as I still need translation.activate(lang_code) for the {% trans %} tags my problem is still the same.
The problem came from the fact that if you use translation.activate(language) then you need to use translation.deactivate().
So that would have required the use of a middleware to make it work properly.
However I found the i18next module allowing to override the locale in the template, so I defined the context 'lang_code' in my view and used {% overridelocale lang_code %} in my template.
