Django site hosting on Heroku "No web processes runnng"
So I tried to host my Django application to Heroku and at first it worked.

How to intergrate API calls in Django-rest framework
I'm trying to build a dashboard app using Django-rest framework and Reactjs for frontend. I'm able to produce required json files for my query. How do I edit my code so as to get different query results for different plots. For example, I have a filter for 'year', 4 types ie. 'segment' here, and 'sale/profit'. I have the required data in my database. Should I make individual query-view for every combination of API calls or is there a better way to modify my code for respective call. I'm noob in Django and have no experience working with react also. Please help. class StatSerializer(serializers.Serializer): segment = serializers.CharField(max_length=25, required=True) sale = serializers.DecimalField(max_digits=12, decimal_places=5, required=True) class Meta: fields = ('segment', 'sale') class StatList(ListAPIView): serializer_class = StatSerializer queryset = superstore.objects.filter(order_date__year=2015).values('segment').annotate(sale=Sum('sales')) def list(self, request): query = self.get_queryset() serializer = StatSerializer(list(query), many=True) return Response(serializer.data) -

How to Intercept and Modify / Alter a Django Request URL?
I have a search box. I search for: <- blank spaces in my search box. My form validation catches this. The URL shows: ++++++++++++++++ If I search for: <script>alert(1);</script> The URL shows: <script>alert%281%29%3B<%2Fscript> The Question Where in Django can I alter / change / modify the request that determines the request URL? I'm thinking middleware but I haven't found an example. Would I have to create an entirely new HttpRequest from scratch? Why do I want to? I want to encode the URL differently. For example, strip all punctuation from the q= value, replace whitespace, strip, replace single spaces with + to have cleaner URLs. Really looking for a clear example with CODE. -

Why not receiving post body dict - Django
I'm using manual built form (not the Forms.form or ModelForms.form) in Django. <div class="container"> <div id="tabs-contents"> <div id="infos" class="tab-content"> <form action="/page/" method="POST"> {% csrf_token %} <div class="infos-form-content"> <div class="infos-row-1"> <input id="field1" type="text" value="" name="field1"> <input id="field2" type="text" value="" name="field2"> </div> <div class="infos-row-2"> <input id="field3" type="date" value="" name="field3"> </div> ... ... </div> <button type="submit">Save</button> </form> </div> </div> </div> And it contains also dynamic input fields (created by JavaScript). When I check the request.body type in the view (after decoding of course request.body.decode('utf-8')) I find it's a string and not a dictionary. Why is that happening ? And how to receive the form data in dict ? -
Django: Renew and set JWTs as HttpOnly cookie using a middleware. Response() returning django.template.response.ContentNotRenderedError
I have a custom middleware where I am adding SimpleJWR HTTP_AUTHORIZATION to every authorized requests as I am using HttpOnly cookies. Also here I have added code to check whether an access token is valid or not. If not, then a request is sent using requests which fetches the new access token and set's it as HttpOnly cookie. So far, I'm able to get the new access token after it expires. But, the url from where I dispatched the request returns this error: raise ContentNotRenderedError( django.template.response.ContentNotRenderedError: The response content must be rendered before it can be accessed. At the first request it works. It returns the response and saves the tokens as HttpOnly cookies but after the token expires and if I again make the request, instead of (what I want to happen) saving the tokens as HttpOnly cookies and returning the same response again, it is returning the error. I think the issue is in the response statements. My middleware: import jwt import datetime import requests import json from rest_framework.response import Response from django.conf import settings class AuthorizationHeaderMiddleware: def __init__(self, get_response=None): self.get_response = get_response def __call__(self, request): access_token = request.COOKIES.get('access') refesh_token = request.COOKIES.get('refresh') print(refesh_token) # check if the access … -

Any suggestions for a Django Rest Framework JWT package that sets and supports HttpOnly cookies?
I've been using djangorestframework-simplejwt for a while but now I want to store the JWT token in the cookies (instead of localstorage or front-end states) so that every request that the client makes, contains the token. So did some research on it and the most relevant result I found was this stackoverflow question, in which the author is using djangorestframework-jwt which has a pre-configured setting for cookies called JWT_AUTH_COOKIE. So figured switching to that package but then ended up finding out that the package is pretty much dead. Although there is a fork for the djangorestframework-jwt that is recommended to use instead, I was wondering if anyone has any better suggestions of packages or anyways for setting the JWT token in an HttpOnly cookie in the response even in djangorestframework-simplejwt package or something. -

Celery container crashes when using django cache_page (InvalidCacheBackendError)
I am facing an issue with my Django webapp project. I am running a containerized environment using Django, Postgres, Redis and Celery.

Django creating dependent dropdown menus using pyodbc queries
I'm trying to create a dependent dropdown menu in django. Basically, I have 3 menus, which are Division, District and Store. What I need is that depending on the value selected on Division, Disitrict will be filtered, and depending on the district, store will be filtered.

Django Model with composite primary key didn't update
I have a model with composite primary key class ChatUserModel(CModelMixin): user = models.OneToOneField(Users, models.DO_NOTHING, primary_key=True) chat = models.ForeignKey(ChatModel, models.DO_NOTHING) chat_permissions = models.IntegerField(blank=True, null=True) class Meta: managed = True db_table = 'tbl_chat_users' unique_together = (('user', 'chat'),) And service, which use this model def connect_to_chat(self, serializer: ChatInfoSerializer) -> ChatUserModel: chat_id = serializer.validated_data.get('chat') if ChatUserModel.objects.filter(user_id=self.user.id, chat_id=chat_id).exists(): raise exceptions.ValidationError('User is already member of this chat') bundle = ChatUserModel.objects.create(user=self.user, chat_id=chat_id) if self.user.status == enum_status_of_user.confirmed_email: bundle.chat_permissions = ChatPermissions.canWrite.value bundle.save() return bundle when running, I get an error: django.db.utils.IntegrityError: duplicate key value violates unique constraint "pk_tbl_chat_user_user_id" DETAIL: Key (user_id, chat_id)=(26b01213-b9c3-4abc-b1d2-f7213781a2c6, 3054495f-8a92-49fc-8dd7-7c0700319d87) already exists. I think Django instead update model does create, but i don't know why. Parameter force_update=True didn't help me.
