i need help. trying read file content using url , return content response in html format getting following error.

error:

 traceback (most recent call last):   file "/usr/local/lib/python2.7/dist-packages/django/core/handlers/exception.py", line 41, in inner     response = get_response(request)   file "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py", line 187, in _get_response     response = self.process_exception_by_middleware(e, request)   file "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py", line 185, in _get_response     response = wrapped_callback(request, *callback_args, **callback_kwargs)   file "/opt/lampp/htdocs/rework/nuclear/rfi/secure/plant/views.py", line 217, in view_reactor     pers = user.objects.get(pk=request.session['id'])   file "/usr/local/lib/python2.7/dist-packages/django/contrib/sessions/backends/base.py", line 57, in __getitem__     return self._session[key] keyerror: u'id'

i explaining code below.

site = 'http://127.0.0.1:8000/'     my_list = []     my_list.extend(['home', 'view_reactor'])     if request.get.get('file') not none , request.get.get('file') != '':         file = request.get.get('file')         if file in my_list:             full_path = site+file             response = urllib.urlopen(full_path)             lines = response.readlines()             return httpresponse(content=lines, content_type="text/html")         else:             return render(request, 'plant/home.html', {'count': 1})     else:         return render(request, 'plant/home.html', {'count': 1})   def view_reactor(request):     """ function serch screen. """      pers = user.objects.get(pk=request.session['id'])     root = []     user_name = pers.uname     count = 1     root.append(         {'username': user_name,          'count': count          })     return render(request, 'plant/view_reactor.html',                   {'user': root, 'count': 1})

here passing the value in query string http://127.0.0.1:8000/createfile/?file=view_reactor , need response of http://127.0.0.1:8000/view_reactor page in html format. in code getting error. please help.

the error saying there no id key in session dictionary. in following line:

pers = user.objects.get(pk=request.session['id'])

and me looks redundant user this. should able user doing this:

pers = request.user

provided have auth middleware installed.

second option (not tested though):

pers = user.objects.get(pk=request.session['_auth_user_id'])

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
