I'm trying to get a local copy of a Django site working. The production site works just fine on login, but my local instance doesn't redirect to the profile page after completing the login form.
This is the login_page view:
def login_page(request): profile_page = HttpResponseRedirect('profile') if request.user.is_authenticated(): return profile_page form = LoginForm(request.POST or None) if request.POST and form.is_valid(): user = form.login(request) if user: login(request, user) return profile_page return render(request, 'login.html', {'form': form}) This is what the debug output of the server shows:
Performing system checks... <function home_page at 0x7f77ad696c08> System check identified no issues (0 silenced). July 08, 2017 - 03:21:39 Django version 1.9.1, using settings 'mysite.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C. [08/Jul/2017 03:21:49] "GET / HTTP/1.1" 200 3276 [08/Jul/2017 03:21:50] "GET /login HTTP/1.1" 200 2370 [08/Jul/2017 03:21:57] "POST /login HTTP/1.1" 302 0 [08/Jul/2017 03:21:57] "GET /profile HTTP/1.1" 302 0 [08/Jul/2017 03:21:57] "GET /login?next=/profile HTTP/1.1" 200 2370 After the above, the browser is left at http://127.0.0.1:8000/login?next=/profile and just displays the standard login page.
Again, identical code is working on the same version of Django in production (though running through gunicorn/nginx instead of django-admin runserver), so it makes me think that there's something in my Django config that I'm missing rather than an actual code problem.
urls.py entries:
from accounts import urls as account_urls ... url(r'^', include(account_urls)), accounts/urls.py:
from django.conf.urls import url import accounts.views urlpatterns = [ url(r'profile/?$', accounts.views.user_profile_page, name='user_profile_page'), Profile view (this never gets triggered AFICT - sticking a breakpoint in there doesn't help):
@login_required def user_profile_page(request): """Returns user home page, with respective user status of surveys.""" print "User profile accessed: %s" % request // user specific data here context = {'some': some, 'data': data, 'here': here, } return render(request, 'accounts/profile.html', context) Also interesting: resolve_url doesn't seem to do the remapping like I would expect:
(Pdb) resolve_url('/profile') '/profile' Shouldn't that point to acccounts/profile or 127.0.0.1:8000/profile or something like that?
This is the AUTHENTICATION_BACKEND's 'authenticate' method that is getting executed (not sure how this differs from standard Django). All of the answers here imply that authenticate needs to accept the request argument - can I update this method to append something here?:
def authenticate(self, username=None, password=None, **kwargs): UserModel = get_user_model() if username is None: username = kwargs.get(UserModel.USERNAME_FIELD) try: if username is not None: username = username.lower() user = UserModel._default_manager.get_by_natural_key(username) if user.check_password(password): return user except UserModel.DoesNotExist: # Run the default password hasher once to reduce the timing # difference between an existing and a non-existing user (#20760). UserModel().set_password(password) 5 Answers

Changed in Django 1.10: In older versions, when you’re manually logging a user in, you must successfully authenticate the user with authenticate() before you call login(). Now you can set the backend using the new backend argument.
If you using Django<=1.10, you must use authenticate method before you login. Otherwise, you have to feed authentication backend at least in login method. Here is the code snippet from django docs.
username = request.POST['username'] password = request.POST['password'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) # Redirect to a success page. ... else: # Return an 'invalid login' error message. ... Answers 2
try this
from django.shorcuts import redirect from django.contrib.auth import authenticate def login_page(request): profile_page = HttpResponseRedirect('profile') if request.user.is_authenticated(): return profile_page form = LoginForm(request.POST or None) if request.POST and form.is_valid(): user = authenticate(request,username=form.cleaned_data['username'],password=form.cleaned_data['password']) if user: login(request, user) return redirect('profile') Answers 3
Try modifying:
profile_page = HttpResponseRedirect('profile') to:
profile_page = HttpResponseRedirect(reverse('profile')) Answers 4
try with class bassed views
class Login(FormView, View): template_name = 'login/login.html' form_class = AuthenticationForm success_url = reverse_lazy("your_succes:url") def dispatch(self, request, *args, **kwargs): if request.user.is_authenticated(): return HttpResponseRedirect(self.get_success_url()) else: return super(Login, self).dispatch(request, *args, **kwargs) def form_valid(self, form): login(self.request, form.get_user()) return super(Login, self).form_valid(form) Answers 5
to get your page redirected to some other URL you actually require to use import redirect from Django shortcuts and utilize this to redirect to the required URL this is the ones available(as you already have created a Django website) in urls.py you can Have a look at the youtube video link

Another thing You may want to try is using templates as it makes Web developer's life Easier and safer
Answering the Question about gunicorn/nginx the application server has its default route set, you might have done it in the production build, to the profile page when the session info is added.
Also, check with the naming of the page profile it presently does not have any file extensions
you can also try with URL reverse
