How to run a telegram bot in django?
I want to run a telegram bot in django and have it run with the command "python manage.py runserver". I tried to do this with subprocess, but it gives an error and because of this there is a conflict with the launch of several bots.

Stripe Portal url not secure Python
I'm working on a Django application integrated with Stripe, and I'm facing a security issue related to user subscription management through the Stripe portal. Currently, I provide a simple link for users with subscriptions to access the portal. However, I've noticed that if I copy the link from the browser tab that the view generate and paste it into a private tab in another browser, the portal loads up, allowing access to someone else's subscription details. an example of the url generated : https://billing.stripe.com/p/session/test_YWNjdF8xSGFuNG5KV3p0WnBRQUJ4LF9POHM5UWlrYlhtM0FadVZmV3NUU3hQFMrgrrgg0HK1DtM1hxe This presents a significant security concern since an unauthorized user who obtains the URL could potentially manipulate the billing information of a subscriber. so my view : def customer_portal(request): # Authenticate your user. customer_id = request.user.customer.id # Create a session. session = stripe.billing_portal.Session.create( customer=customer_id, return_url='http://127.0.0.1:8000/account/billing/', ) # Directly redirect the user to the portal. return redirect(session.url) the link : <h4><a href="{% url 'subscriptions:customerPortal' %}">Manage Billing</a></h4> the urls : path('billing/portal/', customer_portal, name='customerPortal'), I'm doing something wrong ? -
Dajngo: Pagination in search results with Class-based views
I want to paginate by keywords that I enter in the form. I use the following class def pageNotFound(request, exceprion): return HttpResponseNotFound("<h2>Page not found</h2>") def get_quotes(): top_tags = get_top_tags() context = { "top_tags": top_tags, "functional_menu": functional_menu, } return context class Main(ListView): model = Quote paginate_by = 10 template_name = "quotes/index.html" context_object_name = "quotes" def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context.update(get_quotes()) return context class SearchedResults(ListView): model = Quote paginate_by = 10 template_name = "quotes/index.html" context_object_name = "quotes" def get_queryset(self): query = self.request.GET.get("search_query") if query: queryset = Quote.objects.filter( Q(quote__icontains=query) | Q(tags__name__icontains=query) | Q(author__fullname__icontains=query) ).distinct() else: queryset = super().get_queryset() return queryset def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) return context The problem is that when you go to the next page, the form field is cleared and the query takes the value None query=None. The entire pagination becomes undefined. How to save queryset when crossing pages in pagination? -
Django returns TemplateDoesNotExist for namespaced app templates which are rendered by class views but works for plain function views
I'm new to Django and have a project myproject and inside is an app, users. I can't figure out why name spacing the my templates in a subdirectory inside of a folder called templates within the users apps (so the path is myproject/users/templates/users/) does not work for class based views but it works fine for regular function views. When using a class based view I get error message Templateloader postmortem saying: django.template.loaders.app_directories.Loader: /home/me/projectmainfolder/myproject/users/templates/signup_form.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/me/projectmainfolder/penv/lib/python3.10/site-packages/django/contrib/admin/templates/signup_form.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/me/projectmainfolder/penv/lib/python3.10/site-packages/django/contrib/auth/templates/signup_form.html (Source does not exist) When I move the template out of the name spaced sub-directory and into templates it works fine. users/urls.py is: from django.urls import path, include from . import views app_name = "users" urlpatterns = [ path("accounts/", include("django.contrib.auth.urls")), # works fine path("accounts/test", views.testdef, name="test"), #doesn't work path("accounts/signup/user", views.UserSignupView.as_view(), name="signup_form"), ] The regular function testdef is : def testdef(request): return render(request, "users/test.html") The class view UserSignupView is: class UserSignupView(CreateView): model = CustomUser form_class =UserProfileSignupForm template_name = 'signup_form.html' def somefunction(self, **kwargs): ...

Django ORM: have model field always return a constant
I am extending Django model into a few child classes: Model –> SampleModel –> SampleModelA –> SampleModelB –> SampleModelC –> SampleModelD All child models (A,B,C,D) have field SampleType as Integer. Models A and B may have different SampleTypes (1–5), whereas for models C and D, SampleType is always the same: 1 and 2, respectively. I must preserve SampleType field in all child models for polymorphism purposes, but need models C and D always return 1 and 2, respectively for that field in any record, no matter what query. What is the simplest way to do that? (preferably without taking up disk space for the field) -

Django Authentication Form not working properly
I am trying to create a very basic login system (just to grasp Django's authentication system, nothing fancy). Thing is, when I use the following code (i.e. don't validate authentication form submission), everything works perfectly.

Vue Django app Forbidden (CSRF cookie not set.): 403 Forbidden

When using custom AuthBackend, unable to use request.user.is_authenticated or @login_required decorator
Firstly I'm coming from a PHP background and new to Django. And I'm trying to upgrade a webapp from a PHP framework to Django, keeping the database unchanged. The built-in authentication in Django is bit confusing, as my User table is different to what is expected in django's auth.User modal. In my usecase, I have an Employee entity whose login account is created at the instance of creating the Employee itself. The authentication part I managed to complete by implementing a custom AuthBackend. But now, I'm unable to use the @login_required decorator for other views post-login, because it throws and error 'User' object has no attribute 'is_authenticated'. In order to use is_authenticate method my User modal must then extend from auth.AbstractUser or auth.AbstractBaseUser. How can I keep the original table structure for User modal, but still get around these authentication functions in django? -

In Django, after extending the User model, how to add values to the new model?
