Hello Tomasz, thanks for the quick answer, however your first suggestion doesn't work, since I don't want a queryset, I just want to display a field of a related model for every model in the queryset. The second variant seems to work, even though I always get the result for German language. But I suppose the problem is rather untested i18n in my project than the formfield However I'm wondering how I would transform this concept on Formsets. I think I would somehow need to expand already the formsets __init__ to accept the additional 'request' parameter (otherwise I get "__init__ () got an unexpected keyword argument 'request'"), and then push it forward to the forms __init__.
