Heroku cannot read '/etc/secret_key.txt', No such file or directory:
I successfully deployed a django app to heroku with my settings.py as such: SECRET_KEY = 'the_real_long_secret_key_itself', which of course is not recommended, but that was find for me just in this scenario as it is just a test and can be changed. Now back to my local environment, I decided to hide the key without changing it yet and according to django documents like this: # on settings.py with open('/etc/secret_key.txt') as s: SECRET_KEY = s.read().strip() And it works when I run server locally. But now when I try to commit & push like this: (herokuvirtualenv)tester1@test:~/$ git add -A (herokuvirtualenv)tester1@test:~/$ git commit -m "some editing" (herokuvirtualenv)tester1@test:~/$ git push heroku master It runs but ends up with this error message: remote: with open('/etc/secret_key.txt') as s: remote: FileNotFoundError: [Errno 2] No such file or directory: '/etc/secret_key.txt I have used search engines and there seems to be many ways to do this and it point that this should work, but there seems to be something I am omitting here. Could someone please help out? -
Django change choice before validation
I am trying to update a choice field before it is validated in Django. The reason for this is the choice field in question value is the Id of a model that i want to update. def fuelLogSystemOne(request): entries = FuelLogSystemOneMod.objects.all().order_by('date') products = productsMod.objects.all() if request.method == 'POST': form = forms.AddFuelLogOneForm(request.POST, request.FILES) productid = form['product'].value() product = productsMod.objects.get(id=productid) product_id = request.POST.get('product') form.fields['product'].choices = [(product.product_type, product.product_type)] if form.is_valid(): bucketsRemoved = form['buckets_added'].value() product.stock -= bucketsRemoved product.save(['stock']) instance = form.save(commit=False) instance.staff = request.user instance.save() return redirect('home') else: form = forms.AddFuelLogOneForm() return render(request,'systems/fuellogsystemone.html',{'form':form,'entry':entries,'products':products}) The below part is where i am trying to change the form data before it gets validated so it doesn't say 'Select a valid choice. 1 is not one of the available choices' product_id = request.POST.get('product') form.fields['product'].choices = [(product.product_type, product.product_type)] But when I first submit the form it is still saying 'Select a valid choice.' At what point does Django validate the form because I am changing the form before the is_valid() method and it still hits this error? -
Django REST Framework - cookies not being set via Response.set_cookie() call...?
I have the following standard Response setup in my DRF application: response = Response(data=response, status=status.HTTP_200_OK) I'm then attempting to add a split JWT header.payload and signature to the response headers with a response.set_cookie() call, as follows: max_age = 365 * 24 * 60 * 60 expires = datetime.datetime.utcnow() + datetime.timedelta(seconds=max_age) response.set_cookie( key='JWT_ACCESS_HEADER_PAYLOAD', value=header_payload, httponly=False, expires=expires.strftime("%a, %d-%b-%Y %H:%M:%S UTC"), max_age=max_age ) response.set_cookie( key='JWT_ACCESS_SIGNATURE', value=signature, httponly=True, expires=expires.strftime("%a, %d-%b-%Y %H:%M:%S UTC"), max_age=max_age ) return response I can't see anything wrong with what I have done thus far: Yet, for some reason, the only cookies set on the client side are as follows: What have I done wrong here?? The actual output in the headers seem to be a valid SetCookie value: JWT_ACCESS_HEADER_PAYLOAD=aSasas; expires=Sat, 03-Apr-2021 10:24:31 GMT; Max-Age=31536000; Path=/ JWT_ACCESS_SIGNATURE=asaSasaS; expires=Sat, 03-Apr-2021 10:24:31 GMT; HttpOnly; Max-Age=31536000; Path=/ -
Manage models inheritance in Django admin
I'm developing with my team a Django webapp which provides authentication and users profile creation. Basically, we are dealing with a model Profile which extends django.auth.contrib.models.User implementing One-to-One link method, as shown below model.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) birth_date = models.DateField(default=datetime.date.today) # other custom fields def __str__(self): return self.user.username Since we have registered the model in admin.py, it appears in Django admin panel, as it should be. Then, we have introduced another model PersonalTrainer which is an intherited class of Profile one. admin.py from django.contrib import admin from usermanager.models import Profile, PersonalTrainer admin.site.register(Profile) admin.site.register(PersonalTrainer) Is there any programmatically method to organize PersonalTrainer instances in a such a way they appear both in Profile section and PersonalTrainer section? In other words, we'd like to have a PersonalTrainer instance which appears in auth User model, Profile model and PersonalTrainer model. -

How can I convert my class-based view to function-based views? - Django
I am trying to change all my class-based views to function-based views and I am having difficulty converting the following class: class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, SuccessMessageMixin, UpdateView): model = Post fields = ['image', 'title', 'category', status', 'description'] template_name = 'blog/post-form.html' success_message = 'Your post has been updated.' def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def test_func(self): post = self.get_object() if self.request.user == post.author: return True return False def get_context_data(self, **kwargs): context = super(PostUpdateView, self).get_context_data(**kwargs) context['title'] = 'Update post' context['submit'] = 'Update' return context def get_success_url(self): author = self.object.author return reverse_lazy( 'profile', kwargs={'author': author.username}) The function and form should do exactly what this class-based view does, so if anyone can help me out, please let me know. -
Object level authorization in a Django Rest Framework viewset
I'm creating an API with Django Rest Framework (DRF) and wondering where I should handle object level authorization. So far I've created an Organization model and a custom user model with email being the unique identifier instead of username. Organizations and users are currently connected through a many-to-many field. What I'd like to do is make sure that when a user hits my API they're only able to do the standard CRUD actions on the models that are linked to the users respective organization. As an example here's my current UserViewSet where I've overriden then get_queryset method to filter the User queryset to only return other users who are apart of the same organizations as the user calling the API: class UserViewSet(viewsets.ModelViewSet): serializer_class = UserSerializer def get_queryset(self): User = get_user_model() user = self.request.user organizations = user.organization.all() return User.objects.filter(organization__in=organizations) What's considered best practice to extend these limitations to other viewset actions? For example, if I want to make sure that the user can only create and add other users into the organizations they're linked to, should I override the create method in the viewset and perform a validation there that the organization which was passed in the request data is the … -

Add extra non-model attribute to serializer
I have following scenario: I have a device model with a "deleted" field. When it's true, the device is deleted. I need a endpoint to change the value of that field. I want to do this in a request by giving the device_id and a deleted_flag. I was able to just change the deleted attribute without passing the deleted_flag attribute.

how to load bootstrap in Django?
so I tried loading Bootstrap to Django.

Stripe - Retrieve Customer PaymentIntent history
I am building a platform where I am using Stripe's concept of a parent "platform" account and Connected Stripe accounts that belong to this platform. (e.g. Lyft model) Following Stripe's documentation, when I create a new customer in Stripe, I create it under the main platform account and also store all the payment methods under that customer. When a customer buys something from the Connected account, I follow this doc, where I clone payment method and create a PaymentIntent that is attached to the specific Connected account. And it all works. However, when I try to get a history of customer's transactions (List of PaymentIntents), it returns an empty list because it runs it against the main platform account: stripe.PaymentIntent.list(customer='cus_FJDHFGSJHDF') When I specify a customer AND connected account id, it returns an empty list, because that customer doesn't exist in that Connected account, however, the paymentIntents are present in that Connected account. So, what is the right way to create a PaymentIntent for a customer for a Connected account and then get the history of payments for that customer PER Connected Stripe account? Here is how I clone PaymentMethod and create PaymentIntent: payment_method = stripe.PaymentMethod.create( customer=customer, payment_method=customer.invoice_settings.default_payment_method, stripe_account=stripe_connect_id, ) intent … -

Django: Query `id__in` with UUIDs
In Django, we can use the id__in query with a queryset to filter down a queryset based on a list of IDs. However, by default this will fail if your IDs are UUIDs.
