Edit: [SOLVED] Was using different django version on local host.
I have no idea what to do, my search only yielded this forum topic.
I don't know what to make of SESSION_COOKIE_DOMAIN? so I added to the end of my settings.py:
#Cookie Domain
SESSION_COOKIE_DOMAIN = 'none'
But I still see the error:
Django Version: 1.9.3
Exception Type: AttributeError
Exception Value: 'WSGIRequest' object has no attribute 'session'
edit: I should add that everything worked great when used locally.
What's the traceback?

I suppose it could be installed middleware... or lack thereof?
Do you have the django sessionmiddleware activated?
.
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
I never deactivated it as far as I know.
Is there something i need to do other than make sure that
'django.contrib.sessions.middleware.SessionMiddleware',
is present?
so the middleware ordering also matters but most of it seems fine. The weirdest one is the clickjacking one. try taking that out and reloading and seeing what happens?
same error.
The whole project worked locally, without any django debugging display...
so I'm wondering if there is a specific instruction I need to make the 'session' variable work on pythonanywhere
Hmm I am definitely not aware of anything that strips out sessions. Will investigate a bit. Is this happening just for specific views? (ie. is session availble sometimes?)
Were you using python3.5 with a virtualenv locally?
I have to assume that the problem is global. The session data is only used for a presentation view and a view which serves a text file (for user to download), the latter is only reachable by the user after the former.
from views.py:
def index(request):
context = {}
#### sends form to new visitors
if request.method == 'GET':
# the numbers from which multiples can be chosen
context["quantity"] = quantity
context["operators"] = opChoices
context["limits"] = limits
context["multChoices"] = multChoices
return render(request, 'generator/form.html', context)
### reading submitted form data for parameters
params = {
'quantity': request.POST['quantity'],
'operators': getOps(request.POST),
'attributes': getAttr(request.POST),
'number0': numberSymbol(int(request.POST['leftRange-lower']),
int(request.POST['leftRange-upper']),
getMults(request.POST)[0]),
'number1': numberSymbol(int(request.POST['rightRange-lower']),
int(request.POST['rightRange-upper']),
getMults(request.POST)[1])
}
### generate questions based on collected information
generated_qna = generateQuestions(params)
# line by line data
printed_qna = generatePresentation(generated_qna)
context["params"] = params
request.session["questions"] = printed_qna['questions']
request.session["answers"] = printed_qna['answers']
context["questions"] = request.session["questions"]
context["answers"] = request.session["answers"]
# clean operator symbols for human reading
context["humanOperators"] = (human_list(human_clean(params["operators"])))
return render(request, 'generator/generated.html', context)
def download(request):
context = {}
#### prevents accessing the wrong page
if request.method == 'GET':
# force 404
return HttpResponse("such hack, very disappoint, wow")
### download text files
content = (docText["title"] + "\n"
+ docText["slogan"] +"\n\nQuestions only\n"
+ ''.join(request.session["questions"])
+ "\n"
+ "Questions with Answers\n"
+ ''.join(request.session["answers"]))
response = HttpResponse(content_type='text/plain; charset=utf8')
response['Content-Disposition'] = 'attachment; filename="%s.txt"' % "MathMaker"
response.write(content)
return response
locally I was using python 3.5 no virtualenv.
Ohhhh. It's because you were using django 1.10 locally and 1.9 on pythonanywhere. One is MIDDLEWARE, the other is MIDDLEWARE_CLASSES. I would setup a virtualenv both locally and on pythonanywhere to make sure you have the correct versions for different packages.
Thank you, changing the one variable name fixed it.
Thank you so much conrad.
I will work on my virtualenv game from now on.
