I am in the process of turning a Django project into a multi-language site. For that purpose I am trying to adopt the countries-for-django (github) package.
In one of the templatetags, the code is trying to read the session variable django_country (taken from here), but Django 1.5 trips over reading the request variable from the context.
Exception Type: AttributeError
Exception Value: 'NoneType' object has no attribute 'session'
The code in the template tag is as stated below (the code has been extended since the first post):
class GetCurrentCountryNode(Node):
def __init__(self, variable):
self.variable = variable
def get_current_country(self, context):
from django.template import Context
return context.get('request').session.get('django_country')
def render(self, context):
context[self.variable] = self.get_current_country(context)
return ''
...
@register.tag("get_current_country")
def do_get_current_country(parser, token):
args = token.contents.split()
if len(args) != 3 or args[1] != 'as':
raise TemplateSyntaxError("'get_current_country' requires 'as variable' (got %r)" % args)
return GetCurrentCountryNode(args[2])
When I print the context variable, the print out does not contain any request variable. However, I can see via the Django Toolbar that the variable is existing.
Did the way of reading the context variable change with Django 1.5? I could not find anything in the documentation.
Views.py and template added for completeness.
views.py
...
class StartView(FormView):
form_class = StartForm
template_name = 'home.html'
def form_valid(self, form):
self.request.session['address'] = form.cleaned_data['address']
return HttpResponseRedirect(reverse_lazy('new'))
...
home.html
{% load countries %}
{% get_current_country as country %}
{% get_available_countries as COUNTRIES %}
<head>
...
The code works if
django.core.context_processors.requestis added to theTEMPLATE_CONTEXT_PROCESSORSin thesettings.py.
