django.utils.translation.activate() issue

[tomasz.zawadzinski@…]

django.utils.translation.activate() doesn't affect on form instances. Strings defined in a class of form (ex label, error_messages etc), are translated only in a result of setting a proper cookie or session key.

Please provide us with real code so as we can judge if the problem is in Django or on your side. Did you use ugettext_lazy to mark form class strings for translation?

I'm sorry, everything is fine using ugettext_lazy. I don't know if this problem is worth solving anymore.

code looked like this (other strings were translated properly, these in templates and other helping functions):

from django.utils.translation import ugettext as _

class BookingForm(forms.Form):
   name = forms.CharField(max_length=25, label=_(u'Imię'), error_messages={'required': _(u'Proszę wpisać imię.')})
   [...]

def index(request, lang=''):
   if lang == 'en':
      translation.activate('en')
   elif lang == 'pl':
      translation.activate('pl')

   c = {'form': BookingForm()}
   [...]

This is exactly the reason why ugettext_lazy exists :)
