Are you sure you have activated the request context processor? In
other words, do you have something like this in your settings file?
TEMPLATE_CONTEXT_PROCESSORS = (
"django.core.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"django.core.context_processors.media",
"django.core.context_processors.request",
)
There's more explanation about this in the docs here:

Yeah I thought it would do that but it really doesn't... here's what i
have...
in my view I have:
from django.template import RequestContext
from django.template import Template, Context
[... session variables set here...]
return render_to_response('step3.html',
context_instance=RequestContext(request))
and in my template i have:
Account #:
{{ request.session.AccountNum }}
it prints nothing to the screen unless i explicitly pass a variable.

If you have activated the request context processor, the request is
*automatically* passed to the template. (That was the point of all
this, right?)
So to display the value of request.session['City'], for example, you'd
use this in your template:
{{ request.session.City }}

Re: sessions in template (outside of views)
ok i'm totally lost i guess...
in my view i setup my session variables as such...
request.session['Street2']=request.POST.get('Street2','')
request.session['City']=request.POST.get('City','')
request.session['State']=request.POST.get('State','')
request.session['ZipCode']=request.POST.get('ZipCode','')
and when i want to pass back to the template i am doing the following:
return render_to_response("step2.html", 'form': form},
context_instance=RequestContext(request))
now my question here is how do i pass those session variables back to
the template. I've tried building a data dictionary like this:
{'Street2': request.session['Street2'], 'City':
request.session['City'], ...}
but that does nothing. Please help

Variables that happen to hold session data are no different from other variables. If you want to have access to a variable in a template, you'll have to make the variable available to the template somehow. You can do this by passing the variable to the template yourself, or (in some cases) you can have a context processor do that for you. This is one of those cases: you can have request.session added implicitly if you do what Daniel Roseman wrote and active the django.core.context_processors.request context processor, making sure to always use a RequestContext when rendering the template.

Re: sessions in template (outside of views)
So I have to explicitly pass the session variables to the template to use them? That kind of defeats the purpose of session variables doesn't it? If they are in session we should be able to access them easier than passing them from view to template throughout our application. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

You need to enable the request template context processor. Add (or
uncomment) this line to your TEMPLATE_CONTEXT_PROCESSORS tuple in
settings.py:
'django.core.context_processors.request'
You also need to make sure you're using a RequestContext when
rendering the template. If you're using render_to_response, you need
to do something like this:
return render_to_response('my_template.html',
my_data_dictionary,
context_instance=RequestContext(request))
See
http://www.djangoproject.com/documentation/templates_python/#subclassing-context-requestcontext
for more information.

Re: sessions in template (outside of views)
Hi Bobby,
Typically what I do is set the value from the session into a variable
that I pass into the context.
#in views.py
def my_action(request)
account_num = request.session['AccountNum']
return render_to_response('the_template.html', {'account_num' :
account_num})
#in the_template.html
{{ account_num }}
HTH,
Brandon

sessions in template (outside of views)
i'm trying to view session variables on the screen in a template. I
know the session variable has a value because i've tested it in my
view. I'm trying this in my template but not getting any results:
Account #: {{ request.session.AccountNum }}
What could I be doing wrong?
