Keeping the value salected in the drop-down list after the search
I have got a filter on my page, that filters my items by the category. You can choose the category from a drop-down list and then press search and the filtered content is displayed.

Anyone knows how to solve this? views.py def HomeView(request): item_list = Item.objects.all() item_list = item_list.annotate( current_price=Coalesce('discount_price', 'price')) category_list = Category.objects.all() query = request.GET.get('q') if query: item_list = item_list.filter(title__icontains=query) cat = request.GET.get('cat') if cat: item_list = item_list.filter(category__pk=cat) price_from = request.GET.get('price_from') price_to = request.GET.get('price_to') if price_from: item_list = item_list.filter(current_price__gte=price_from) if price_to: item_list = item_list.filter(current_price__lte=price_to) paginator = Paginator(item_list, 10) page = request.GET.get('page') try: items = paginator.page(page) except PageNotAnInteger: items = paginator.page(1) except EmptyPage: items = paginator.page(paginator.num_pages) context = { 'items': items, 'category': category_list } return render(request, "home.html", context) html: <form method="GET" action="."> <div class="form-group col-md-4"> <label for="category">Category</label> <select id="cat" class="form-control" name="cat"> <option value="" selected>Choose...</option> <option value="" href="/home">All</option> {% for cat in category %} <option value="{{ cat.pk }}"> {{ cat }}</option> {% endfor %} </select> </div> <button type="submit" class="btn btn-primary">Search</button> </form> -

Django REST framework: how to wrap the response with extra fields .... and supply the current response in data field
So, I have the following: class ObjectViewSet( mixins.CreateModelMixin, mixins.ListModelMixin, mixins.RetrieveModelMixin, mixins.DestroyModelMixin, viewsets.GenericViewSet ): """ REST API endpoints for Objects. """ serializer_class = ObjectSerializer queryset = Object.objects.all() This returns, say, for a list GET request: [ { "uuid": "787573a2-b4f1-40df-9e3a-8555fd873461", }, { "uuid": "2ab56449-1be1-47d7-aceb-a9eaefa49665", } ] However, how could I slightly alter this response for mixins to be similar to the following: { success: true, message: 'Some Extra Useful Message', data: [ { "uuid": "787573a2-b4f1-40df-9e3a-8555fd873461", }, { "uuid": "2ab56449-1be1-47d7-aceb-a9eaefa49665", } ] } Is this possible, or should I just write my own custom endpoint Response() and not utilise DRF's mixins capability? So, essentially, switching the custom: Response(data, status=None, template_name=None, headers=None, content_type=None) To: response = { 'success': true, 'message': 'Some Extra Useful Message', 'data': serializer.data } Response(response, status=None, template_name=None, headers=None, content_type=None) -
modifying class based view to add data to logged in user

Cannot set PeriodicTask schedule

Django Reverse Filter Queryset Foreign Key Example Not Working

Best practice for getting data from Django view into JS to execute on page?
I have been told it is 'bad practice' to return data from a Django view and use those returned items in Javascript that is loaded on the page. For example: if I was writing an app that needed some extra data to load/display a javascript based graph, I was told it's wrong to pass that data directly into the javascript on the page from a template variable passed from the Django view. My first thought: Just get the data the graph needs in the django view and return it in a context variable to be used in the template. Then just reference that context variable directly in the javascript in the template. It should load the data fine - but I was told that is the wrong way. So how is it best achieved? My second thought: Spin up Django Rest Framework and create an endpoint where you pass any required data to and make an AJAX request when the page loads - then load the data and do the JS stuff needed. This works, except for one thing, how do I get the variables required for the AJAX request into the AJAX request itself? I'd have to get them … -
How to add a model field calculated by data from to other model?
I have the following models: # models.py class Test(models.Model): name = models.CharField(max_length=40) author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) class Tester(models.Model): test_id = models.ForeignKey(Test, on_delete=models.DO_NOTHING) class TestViewset(viewsets.ModelViewSet): serializer_class = TestSerializers permission_classes = (permissions.IsAuthenticated,) def get_queryset(self): if self.request.user.is_superuser: return Test.objects.all() else: return Test.objects.filter(author=self.request.user) So each test can be made by many testers. My wish is to count how many testers conducted the test , i.e when I do a GET request to the TestViewset I wish to get in addition to current fields [name, author] a count field , for each test which specify how many testers have been tested. Appreciate the help! -

Now here is my views.py class TagFilterView(ListView): model = Post template_name = 'mainapp/tags_.html' def get_queryset(self): object_list = Post.objects.filter(tags=tag).distinct() return object_list Here is my url pattern path('tag/<int:pk>/',views.TagFilterView.as_view(),name='tag_view'), And finally here is the HTML file {% extends 'mainapp/base.html' %} {% block content %} <h1>Tags</h1> {% for post in object_list %} <h2>{{ post }}</h2> {% endfor %} {% endblock content %} I have tried lots of different filter combos and filter tags, but this seems to be the closest I think. So basically I want to know how I can filter posts to the specific tags they have associated with them. So for example, if a post has a programming tag, and I go to /tag/1 or something like that, it will filter so only the posts with the programming tag are shown. … -

Django calculate compounded interest for all objects in model

I have three models: Debtor - which contains the client’s personal information as well as the applicable interest rate, compounding period etc. DebtorAccount – is created whenever a new client is created. It also keeps a running balance and accrued interest.
