Django REST ViewSet create
I have a viewset for employees where I want to add a create definition, such that I can set employer=request.user.pk and add the employee (user). I've tried making a create definition (see code below) but the serializer is always invalid so it returns status 400. I don't know if it's me but there seems to be a lack of documentation on the create function so I can't figure out how to do it correctly. Any ideas? class EmployeeViewSet(viewsets.ModelViewSet): queryset = CustomUser.objects.all() serializer_class = CustomUserSerializer def list(self, request): queryset = self.queryset.filter(employer=request.user.pk) serializer = CustomUserSerializer(queryset, many=True) return Response(serializer.data) def create(self, request): serializer = self.serializer_class(data=request.data) if serializer.is_valid(): CustomUser.objects.create_user(**serializer.validated_data) return Response(serializer.validated_data, status=status.HTTP_201_CREATED) return Response({'status': 'Bad Request', 'message': serializer.is_valid()}, status=status.HTTP_400_BAD_REQUEST) -

How to iterate a queryset and append to a string
I have the following function in my view to generate notifications whenever a user has been removed from a project : for user in project.userProfile.all(): Notifications.objects.create( target=user.user, extra='Users', object_url='', title='The following users have been removed : ' + str(removed_users) , ) Of which removed_users is a queryset containing my UserProfile model.

mark as read django-notifications-hq
I pretty much have django-notifications-hq working except I can't figure out how to mark unread notifications as read after seeing the notifications. I followed along this StackOverflow answer to get the notifications to appear in a dropdown list in the navbar: django-notifications-hq: cannot show notifications But I can't seem to mark them as read. The docs say you can use an API call mark_as_read but it doesn't seem to work. I added mark_as_read to the callback section of the script call here: <script src="{% static 'notifications/notify.js' %}" type="text/javascript"></script> {% register_notify_callbacks callbacks='fill_notification_list,fill_notification_badge,mark_as_read' %} Here's the rest of the navbar code where I have the notifications: {% load notifications_tags %} {% if user.notifications %} <script src="{% static 'notifications/notify.js' %}" type="text/javascript"></script> {% register_notify_callbacks callbacks='fill_notification_list,fill_notification_badge' %} <li class="nav-item"> <div class="dropdown"> <a aria-expanded="false" aria-haspopup="true" class="dropdown-toggle nav-link nav-item arrow-bottom" data-toggle="dropdown-grid" href="#" role="button"><span class="badge badge-light">{% live_notify_badge %}</span></a> <div class="row dropdown-menu"> <div class="col-auto" data-dropdown-content> <ul class="dropdown-grid-menu" id="notice-link"> <a href="{% url 'messages' %}"> {% live_notify_list %} </a> </ul> </div> </div> </div> </li> {% endif %} -

I accidentally deleted my website in django admin/sites page
I was having an issue with the django generated sitemap.xml showing example.com instead of my domain name. I have read that I should change the name of my website in django admin, going to " sites" menu. But instead of modifying it, I deleted it and created a new one with the right domain name. Now, I can still access my website but not my sitemap.xml anymore. When I try to do so, I have the following message error: Site matching query does not exist. Does anyone know how I can solve this? -

How to define two Django fields unique in certain conditions
I want to make Django Model fields unique with two fields(values) in some conditions. there's two fields: 'team', 'type'. And I want to make team manager unique For Example: team=1, type='manager' team=1, type='manager' -> Not available team=1, type='manager' team=1, type='member' team=1, type='member' team=2, type='manager' -> Available I think unique_together('team', 'type') won't work properly with this situation.

How to get the context of a view to another in Django without accessing the database again?
I have a view that lists the items in the cart of a user, to show the user the invoice for their purchase. The code for that view is def invoice_view(request): cart = Cart.objects.get(user=request.user) cart_items = ItemInCart.objects.filter(cart=cart) total_cost = 0 for item in cart_items: total_cost += item.cost return render(request, 'app1/checkout.html', {'cart_items': cart_items, 'total_cost': total_cost}) Now say I need the 'cart_items' list in another view of the same app - to checkout the user. How do I do it without having to access the database again? The methods I found on SO and other forums were storing the information in session data or sending the data as parameters to an HTTP request. Is there an alternative to this? Thanks. -

Setting Up a Language-Switching Button in Django
I'm new to Django and would like some advice on how to set up a single language switching button to switch between two languages (English and Japanese in this case), and specifically how to set up this functionality in a view and access it from a template. In the template, I've arrived at the following which works but it includes repeated code for the form and the button, which obviously isn't great. {% get_current_language as LANGUAGE_CODE %} {% ifequal LANGUAGE_CODE 'en' %} <form action="{% url 'set_language' %}" method="post" id="form_{{ 'ja' }}" > {% csrf_token %} <input name="next" type="hidden" value="{{ redirect_to }}" /> <input name="language" type="hidden" value="{{ 'ja' }}" /> </form> <button class="btn btn-sm btn-outline-primary" type="submit" form="form_{{ 'ja' }}" value="Submit">日本語</button> {% else %} <form action="{% url 'set_language' %}" method="post" id="form_{{ 'en' }}" > {% csrf_token %} <input name="next" type="hidden" value="{{ redirect_to }}" /> <input name="language" type="hidden" value="{{ 'en' }}" /> </form> <button class="btn btn-sm btn-outline-primary" type="submit" form="form_{{ 'en' }}" value="Submit">English</button> {% endifequal %} My apologies for the beginner question but I'd really appreciate some advice as to how to put the above logic into a view and access it from the template. Thanks in advance.
