I know this question had been asked for more than five times but I had tried many solutions as a noob and still weren't able to find out the solution. I had been following the django-channels documentation and instead of room-name I want to display username in the URL but when I try as per instructions this error occurred. This is the image of error. Image of error when I run it on Mozilla firefox and this is what it is saying in terminal Image of error in terminal and this is the line of chatpage urls.py line which is I am trying to display with username path('ChatView/<str:uname>', login_required(views.ChatView.as_view()), name="chatpage"), and this is the line of views.py for chatpage. class ChatView(View): def get(request, username): uname = User.objects.get(username=username) return render(request, 'chatbot/chatPage.html', { 'uname': uname }, context_instance=RequestContext(request)) and this is the Html code that I use for username input: <input class="w-full text-lg py-2 border-b border-gray-300 focus:outline-none focus:border-indigo-500" type="text" placeholder="Enter Your Username" id="username" name="username" value="{{data.username}}" Required> These are the four links of pastebin for whole code: views.py urls.py chatpage.html signin.html -
Complicated Neted Admin Inline
I have a complicated model, where playlists can be created on two levels: UserGroup and User. Further, these playlists are targeted to a specific weekday. So Users/UserGroups can have separate playlists for each day of the week. To manage the user playlists in the admin, I'm looking to add the User and UserGroup an inline of all weekdays, and under each weekday the inline of all songs (for that weekday). Hopefully the image below will clear this up a bit. To add to the confusion, the songs per a specific weekday should include both User songs and also UserGroup songs. My models: UserGroup name = models.CharField(max_length=255) User name = models.CharField(max_length=255) UserGroupSong file = models.FileField() weekday = models.ForeignKey(Weekday, on_delete=models.PROTECT) user_group = models.ForeignKey(UserGroup, on_delete=models.PROTECT) UserSong file = models.FileField() weekday = models.ForeignKey(Weekday, on_delete=models.PROTECT) user = models.ForeignKey(User, on_delete=models.PROTECT) inherit = models.BooleanField(verbose_name='Include songs from user-group for this weekday?') class Weekday(models.Model): day = models.CharField(max_length=255) # Pre-populated with values: Sun, Mon, Tue, Wed, Thu, Fri, Sat Any help will be greatly appreciated. -

Django: How to have a UniqueConstraint across fields in multiple models?
In Django 3.2, can I use the UniqueConstraint feature to enforce uniqueness across multiple models, and can you show me how? I want to add an optional ID field for three models that is unique across all of them. This way, when I get that ID from a URL parameter, I can be sure which model type was requested. For my IDs I have 8 alphanumeric characters to play with. If UniqueConstraints across models is a stupid idea please tell me, because I can just reserve one of my 8 characters for model type identification. -

Django token not valid
I'm trying to create a process to verify a users email before changing it. However, the token keeps getting invalidated. Any help? The views: def _send_verification_email(user=None,email=None,request=None): current_site = get_current_site(request) message = render_to_string('emails/email_verification.html', { 'user': user, 'domain': current_site.domain, 'uid': urlsafe_base64_encode(force_bytes(user.pk)), 'token': default_token_generator.make_token(user), 'email':urlsafe_base64_encode(force_bytes(email)), 'email_unencoded':email, }) user.send_email(mail_subject='Verify your email address', message=message) def verify_changed_email(request,uidb64=None,token=None,email=None): try: uid = urlsafe_base64_decode(uidb64).decode() user = Account.objects.get(pk=uid) except(TypeError, ValueError, OverflowError, Account.DoesNotExist): user = None if user is not None and default_token_generator.check_token(user, token): email = urlsafe_base64_decode(email).decode() user.email = email user.save() auth.login(request, user) messages.success(request, 'Your email has been changed.') return redirect('/') else: messages.error(request, 'An error has occurred. This link is not valid.') return redirect('/') Form validation, this works. if form.is_valid() and account_settings_form.is_valid(): self.object = form.save() try: user = Account.objects.get(id=self.request.user.id) if account_settings_form.instance.email != user.email: _send_verification_email(email=account_settings_form.instance.email, user=user, request=self.request) account_settings_form.instance.email = user.email messages.success(self.request,'We sent you an e-mail for further verification!') account_settings_form.save() except ValueError as e: messages.error(self.request, e) return self.render_to_response(self.get_context_data(form=form)) The URL in email, and urlpatterns http://{{domain}}{% url 'accounts:verify_changed_email' uidb64=uid token=token email=email %} path('change-email/<uidb64>/<email>/<token>/',account_views.verify_changed_email,name='verify_changed_email'), It keeps failing this check, the token keeps getting invalidated: if user is not None and default_token_generator.check_token(user, token): Any idea why it keeps failing? What the solution might be?
