How I can use a django variable in if statement of django template into a javascript string variable
I want to add a div to my page using a javascript variable. This div must take a class right or left ,but my if condition doesn't work in this variable, And it works if I try it without javascript. This is my view : def chat(request,sender_id,receiver_id): if request.user.is_authenticated: if request.user.profile == 'C' or request.user.profile == 'A': user = User.objects.filter(id=request.user.id).get() receiver_user = User.objects.filter(id=receiver_id).get() if request.user.profile == 'A': chat = Chat.objects.filter(Q(sender_id=sender_id) | Q(receiver_id=sender_id)).all() elif request.user.profile == 'C': chat = Chat.objects.filter(Q(sender_id=sender_id,receiver_id=receiver_id) | Q(sender_id=receiver_id,receiver_id=sender_id)) context = { 'user': user, 'chat': chat, 'receiver_user': receiver_user, } return render(request,'chat/chat.html',context) return render(request, 'Login/logout.html') And this is my javascript : $(document).ready(function(){ setInterval(function(){ $.ajax({ type: 'GET', url : "{% url 'getMessages' request.user.id receiver_user.id %}", success: function(response){ console.log(response); $("#display").empty(); for (var key in response.chat) { var temp='<div class="msg-box {% if request.user.id == chat.sender_id %} right {% else %} left {% endif %}">\ <div class="details">\ <p class="msg">'+response.chat[key].message+'</p>\ <p class="date">'+response.chat[key].msg_time+'</p></div></div>'; $("#display").append(temp); } }, error: function(response){ console.log('An error occured') } }); },100); }); -
Django Polymorphic Serializer Object of type ListSerializer is not JSON serializable
I'm working on a django view to return a nested list inside another list of records, to do this I use a nested serializer. The thing is that nested serializer is a Polymorphic serializer that decomposes to many other serializers. When I'm using a normal serializer instead of the polymorphic one the approach works fine, but when I use a polymorphic serializer it gives the following error Object of type ListSerializer is not JSON serializable Here is how I'm calling the first serializer in my view return Response(serializers.FormEntriesHistorySerializer(forms,many=True,context={'device_id': kwargs.get('device_id')}).data) And this is the parent serializer class FormEntrySerializer(serializers.ModelSerializer): #form = FormSerializer(read_only=True) response_set = ResponsePolymorphicSerializer(many=True,read_only=True) class Meta: model = models.FormEntry fields = '__all__' def to_representation(self, instance): response = super().to_representation(instance) response["response_set"] = sorted(response["response_set"], key=lambda x: x["id"],reverse=True) return response def validate(self, attrs): print("Validation in on going") return attrs The error is triggered by the ResponsePolymorphicSerializer, as I said this approach works fine if I use a normal serializer instead. But in this case I need to do it with the polymorphic. Here's my polymorphic serializer's definition class ResponsePolymorphicSerializer(PolymorphicSerializer): model_serializer_mapping = { models.FreeTextResponse: FreeTextResponseSerializer, models.ShortTextResponse: ShortTextResponseSerializer, I'd gladly appreciate some guidance on this. Thanks. -

Form not submitting to database in Django
I have created a form in Django and the information from this form must be registered in the database. But I have a problem. The information is not recorded in the database. I guess it's the JavaScript file that's blocking it. I remove the JavaScript file and the form works fine. But I don't want to remove the JavaScript file. How can I solve this problem? views.py def index(request): if request.POST: fname_lname = request.POST.get('name') number = request.POST.get('number') newForm = models.Form(fname_lname=fname_lname, number=number) newForm.save() return render(request, 'index.html') return render(request, 'index.html') model.py class Form(models.Model): fname_lname = models.CharField(max_length=50) number = models.IntegerField(max_length=15) send_date = models.DateTimeField(auto_now_add=True) index.html <div class="formbg"> <div class="formcolor"> <form class="forminput" method="post" action="/"> {% csrf_token %} <div class="label"> <label class="labels">Ad və Soyadınız <span>:vacibdir</span></label> <div class="input"> <input name="name" required type="text" class="inputs" /> </div> </div> <div class="label"> <label class="labels">Telefon nömrəniz <span>:vacibdir</span></label> <div class="input"> <input name="number" required type="number" class="inputs" /> </div> </div> <div class="formbut"> <button type="submit" class="btnsubmit">Göndər</button> </div> </form> </div> </div> </div> </div> <!-- SECTION19 --> <!-- SECTION20 --> <div class="security"> <i class="fa-solid fa-lock"></i> <p>SİZİN MƏLUMATLAR YADDAŞDA QALMIR VƏ 3-CÜ TƏRƏFƏ GÖSTƏRİLMİR</p> </div> <!-- SECTION20 --> <!-- SECTION21 --> <div class="finish"> <p>Məxfilik siyasəti</p> <h1>* - Q7 GOLD KİŞİ GÜCÜNÜN FORMULU</h1> </div> <!-- SECTION21 --> <script src="{% static … -
Django not redirecting to the web page

Django doesn't create session cookie in cross-site json request
I want to make cross-site JavaScript call from third-party domain (in this case my desktop/localhost server) to my remote Django server hosted on my_domain.com/ and calling REST WS exposed on my_domain.com/msg/my_service with using session/cookies for storing session state. But when I call this service (hosted on remote Django server) from my desktop browser or localhost Django server (JS is in index.html), Django doesn't create session cookie and on remote server are doesn't store session state.

Django Framework: Reading Data from MSSQL-Database directly? Or import the dataset to sqlite3?
I would like to build an admin dashboard in Django framework. So far I have only worked with sqlite3 databases in Django. However, the admin dashboard should read statistics from an MSSQL database and display them accordingly. (Sales figures as a graph, other sales in a table, etc.) The turnover figures are very extensive. There are several thousand entries per month and the client would like to be able to filter by any date period. Only data from the MSSQL database should be read. Writing or updating the data is not desired. So far this is no problem, but I wonder what is the better solution to implement the project. Should I connect the MSSQL database directly to Django or should I read the MSSQL database in certain intervals and cache the "results" in a sqlite3 database? Caching seems to me to be the nicer solution, as we don't need real-time data and the performance of the MSSQL server might not suffer as a result. But I would have to build an additional connector to transfer the data from MSSQL to sqlite3. How would you approach such a project? Short version: I´d like to display data in django-framework App, should … -

Django IsAuthenticated views always return 403

django transition between pages with saving data
Tell me how to implement, I just can’t figure it out, I’m still learning. Page1 opens and is created with forms.ModelForm +Meta. It has several inputs (text, selects, date) and 2 more inputs: input_hidden and input_text with the "select" button, as well as the "submit" button (sending to save to the database). By clicking on the "select" button, Page2 opens (like a reference book) with a table and a selection button, the desired row is selected in the table through the radiobutton and by pressing the selection button return to Page1 with data, so that the id of the selected element is recorded in input_hidden in value, and the text of the element string itself was written to input_text. At the same time, if before pressing the button on Page1 data were entered into some other inputs, then when returning from Page2, they retained their values. I can assume that it is possible to do something with saving data through a session, or some other simpler way to organize such a process. -
