Django CORS requests creating 403 Forbidden Error only on server
I have an application which uses Django for the backend and react for the frontend so I setup django-cors-headers. When I tested the application locally with the settings I added, I had no issues. But I deployed to my server, I kept getting 403 error on API requests (except GET requests).

Django workaround to use window function call in an aggregate function?
I'm trying to calculate customer order frequency. First use a window function to get the previous order date then annotate the days since the last order. from django.db.models import Avg, F, Window from django.db.models.functions import ExtractDay, Lag, TruncDate orders = ( Order.objects .annotate( prev_order_date=Window( expression=Lag('paid_at', 1), partition_by=[F('customer_email')], order_by=F('paid_at').asc(), ), days_since_last=ExtractDay( TruncDate('paid_at') - TruncDate('prev_order_date') ), ) ) Then group by customer_email before calculating the average frequency. customer_data = ( orders.values('customer') .annotate(avg_frequency=Avg('days_since_last')) ) Unfortunately this throws an error. Does anyone know of a workaround or know of an alternate way to calculate the average frequency? psycopg2.errors.GroupingError: aggregate function calls cannot contain window function calls -
Django request.session empty between views using JWT
I'm having trouble with using request.session in Django (using JWT for authentification) to keep some user's parameters. I am well aware I have to specify INSTALLED_APPS = [ 'django.contrib.sessions', MIDDLEWARE = [ 'django.contrib.sessions.middleware.SessionMiddleware', REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_jwt.authentication.JSONWebTokenAuthentication', 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.BasicAuthentication', but I think there is something I don't get and I think it is related to the fact I am using JWT. I can store some data in request.session when doing an API call (view) but it won't exist anymore on another one. @api_view(["POST"]) def updateFilters(request): # récupère les filtres dans la session filtres = request.data for key, value in filtres.items(): request.session[key] = value #it's ok here return Response("Filters updated") @api_view(['POST']) def testAPI(request): #empty here !!!!! print(request.session.items()) return Response("Test") Could someone explain what is wrong and maybe propose a solution ?

Django - pagination based on search criteria
I am having issues getting results when clicking on page 2 and above - most likely due to url issues. I have a list of names and if I search on e.g. "John" I want them to be separated by pages if number of names > e.g. 10.

Django: how to refresh html content on new database entry
I am developing a MQTT Dashboard app with django. I have a mqtt thread running in background, periodically polling for data from remote device and saving it as a database (MariaDB) row. I also have a view that displays this row in simple table. Now, what I want to do is to refresh this view (without page reload) when new data appears and my question is how to do that. I thought of two different approaches: Use JS's setInterval triggering ajax call to periodically refresh content. Problem here is that I'm not really proficient with JavaScript nor jQuery so I would love to get simple example how to do that Somehow refresh data from within on_message function which is called when mqtt gets new data. Problem here is that I have no clue if it is even possible I would appreciate any explanation of above or even more some description of different, more proper way to do that. Here is my code: part of template with content i want to refresh: <div class="row mb-4 justify-content-center text-center"> <h1 class="text-uppercase text-white font-weight-bold">{% translate "Parameters" %}</h1> <table id="device-parameters-table"> <thead> <tr> <th scope="col">{% translate "Parameter" %}</th> <th scope="col">{% translate "Value" %}</th> <th scope="col">{% translate … -

Django: how to add a step among the auth login code
I'm building out my first Django Project, and I'm always grateful that authentication steps are provided in modern frameworks, but I'm having trouble seeing how/where to customize the login process to do an additional step behind the scenes. I followed a tutorial to use the Django authentication, and everything is working great. I made a registration/login.html page that includes 'next' for where to take the users. I include the Django urls for authentication in mysite/urls.py: urlpatterns = [ path('familytree/', include('familytree.urls')), path('admin/', admin.site.urls, name='admin'), path('accounts/', include('django.contrib.auth.urls')), ] In settings.py, I specify that I want users to go to the dashboard page after logging in: LOGIN_REDIRECT_URL = 'dashboard' LOGOUT_REDIRECT_URL = 'landing' The question: I'd like to add one other step: after a user successfully authenticates, I'd like to make a record in a new logins table, and then let them continue on to the dashboard. Where's the right place to add this step? At first I was thinking I could change the LOGIN_REDIRECT_URL to some other step (and then have that proceed to dashboard), but what I want isn't really a url.... not sure if middleware would be more appropriate? OR is there some way to sort of extend the login code … -

How to cumsum two models related by an intermediate model using Django ORM
Problem Let's say I have one table called Price which is a timeseries with a timestamp, a value and the difference of previous day. To simplify the table I have put only the dates not the hours, mins, etc.: timestamp value difference 2021-01-21 500 500 2021-01-22 1000 500 2021-01-23 1500 500 2021-01-24 2000 500 2021-01-25 2500 500 Those values might be incorrect and a user might correct it at any point in time using a second table called CorrectedPrice. A user can correct the start value even before the date of the first Price value: timestamp value 2021-01-15 1000 2021-01-23 500 By merging those two informations the resulting queryset between date 2021-01-22 and 2021-01-26 should be: timestamp value 2021-01-21 1500 2021-01-22 2000 2021-01-23 1000 2021-01-24 1500 2021-01-25 2000 Django Models We have a Stock model: class Stock(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.Charfield(unique=True) A Price model: class Price(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) value = models.IntegerField() difference = models.IntegerField() # done with a signal on pre_save timestamp = AutoCreatedField() stock = models.ForeignKey(Stock, on_delete=models.CASCADE) and then we have the CorrectedPrice model: class CorrectedPrice(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) value = models.IntegerField() timestamp = AutoCreatedField() stock = models.ForeignKey(Stock, on_delete=models.CASCADE) What … -

Facebook Login By Using Custom User Model Django
I have a custom User model named Account. I have an activation system so by default is_active is False. In manual login, users receive an e-mail address for an activation link then login to their account. But also I added social media login. I use django-allauth for that. When I login with facebook, it says that user is inactive because my is_active is set to False by default. How can I solve this question and make the social account user to login to the website without any problem? Can i set the is_active=True only for social media users? or do i have to do something else? -
Can I add a form in django html?
I want to add comments form a specific html which has it's own views and models and I do not want to create a new html file like comment.html which will only display the form and its views. I want users to be able to comment right underneath a post, so that users don't have to click a button such as "add comment" which will take them to a new page with the "comment.form" and then they can comment. But I'm stuck. I can add comments manually from the admin page and it's working fine, but it seems that I have to create another url and html file to display the comment form and for users to be able to add comments(btw I'm trying to build a sports related website). Thanks in advance! My models.py: class Transfernews(models.Model): player_name = models.CharField(max_length=255) player_image = models.CharField(max_length=2083) player_description = models.CharField(max_length=3000) date_posted = models.DateTimeField(default=timezone.now) class Comment(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) transfernews = models.ForeignKey(Transfernews, related_name="comments", on_delete=models.CASCADE) body = models.TextField() date_added = models.DateTimeField(auto_now_add=True) def __str__(self): return '%s - %s' % (self.transfernews.player_name, self.user.username) My forms.py : class CommentForm(forms.ModelForm): class Meta: model = Comment fields = ('body',) My views.py : def addcomment(request): model = Comment form_class = CommentForm template_name … -
Data doesn't get submitted to database from Django forms using classed based views
I'm am trying to make a registration page for Companies and the whole flow is working fine using froms in Django. Though when I fill out the form with data and hit submit it redirects me to my index page and doesn't show any error. But when I check the database in /admin the object/data is not submitted. Any idea what the "error" could be? I'm using class based views and I've added my model in admin.py admin.site.register(Company) My urls.py path looks like this: path('createCompanyProfile/', CompanyFormView.as_view(), name = "createCompanyProfile"), models.py: class Company(models.Model): companyName = models.CharField(max_length = 145) description = models.TextField() websiteURL = models.CharField(max_length = 100) relationToDjango = models.TextField() phoneNumber = models.CharField(max_length = 11) email = models.CharField(max_length = 100) mainContact = models.CharField(max_length = 50) streetName = models.CharField(max_length = 45) houseNumber = models.CharField(max_length = 25) postalCode = models.CharField(max_length = 4) region = models.CharField(max_length = 45) def __str__(self): return '{} {} {} {} {} {} {} {} {} {} {}'.format(self.companyName, self.description, self.websiteURL, self.relationToDjango, self.phoneNumber, self.email, self.mainContact, self.streetName, self.houseNumber, self.postalCode, self.region) class CompanyForm(ModelForm): class Meta: model = Company fields = '__all__' views.py: class CompanyFormView(FormView): model = Company template_name = "company/createCompanyProfile.html" form_class = CompanyForm success_url = '/' def form_valid(self, form): return super(CompanyFormView, self).form_valid(form) createCompanyProfile.html <form …
