django variable of one view to another from session -

i m confused on , dont have idea how this.. have view have listed news news table. display news have passed context data in list view. here view

class singlenewsview(listview): model = news form_class = searchform template_name = "single_news.html"  # def post(self, request, **kwargs): #   print "request" #   form = searchform(request.user)    def get(self, request, pk, **kwargs):      #form = searchform(request.user)     self.pk = pk      self.pub_from = request.get.get('pub_date_from',false)     self.pub_to = request.get.get('pub_date_to',false)     self.crawlers = request.get.get('crawler',false)       print self.crawlers       return super(singlenewsview,self).get(request,pk, **kwargs)    def get_context_data(self, **kwargs):      context = super(singlenewsview,self).get_context_data(**kwargs)     context["form"] = searchform     if self.pub_from , self.pub_to , self.crawlers:         context["something"] = news.objects.filter(category_id=self.pk).filter(published_date__range=(self.pub_from,self.pub_to), crawler=self.crawlers)     else:         context["something"] = news.objects.filter(category_id=self.pk)      return context 

and have written view referenced django doc download news in csv format.. have included search form filter news. in first view have passed context["something"] display list of news in template. want download news in csv. have written view this

def csvview(request):  response = httpresponse(content_type="text/csv") response["content-disposition"] = 'attachment; filename=somefilename.csv"'  some_val = request.session["something"] print some_val print "this"  writer = csv.writer(response)   writer.writerow(some_val) return response 

this next view download csv. here trying download news come after filter. in first view context["something "] gives list of news. did dont know how it. lastly m trying value of contxt["something"] session failed in too. how can value of 1 view another. or have better idea how can download news returned context["something"]. doing wrong.

setting data in context not put in session. need set data in session store there. also, storing objects directly in session not idea. may have serialize them.

better way create list of pks of objects want session.

something like:

def get_context_data(self, **kwargs):      context = super(singlenewsview,self).get_context_data(**kwargs)     context["form"] = searchform     if self.pub_from , self.pub_to , self.crawlers:         qs = news.objects.filter(category_id=self.pk).filter(published_date__range=(self.pub_from,self.pub_to), crawler=self.crawlers)     else:         qs = news.objects.filter(category_id=self.pk)     context["something"] = qs     #set data in session     self.request.session['something_pks'] = [ i.pk in qs ]     return context 

then in csvview can them `request.session['something_pks'] , query objects.
