JWT validation in class based view django
I've implemented jwt authentication in django using Django-graphql-jwt library, now I want to allow get/post on my endpoint (/graphql) only for requests with JWT token. There are examples in django-graphql-jwt documentation like @login_required, but I don't want to put a decorator above every query and mutation. So, I've decided to restrict an access to a view. I added path('graphql/', PrivateGraphQLView.as_view()) in url.py but how can I implement request checking for a valid token in the header? from graphene_django.views import GraphQLView class PrivateGraphQLView(GraphQLView): pass -
Adding Semantic UI React value of Form.Select into variable I post into my Django API
I'm new to React and I try to understand how I can add Form.Select value into my variables that I post into my Django API. When I only use Form.Input it works ok but when I add a Form.Select value doesn't passed into the userform. I saw that using event.target.elements.inputname.value is not possible for Form.Select, but after a lot of hours trying to make this works ... it looks like I'm unable to do it. errors shown is : Uncaught TypeError: Cannot read property 'value' of undefined Your help would be much appreciated.

Upgrading Django 1.11 to 3.X/Python2.7 to 3.7
I have a fairly old website running Django 1.11 and Python 2.7. I am not sure why it doesn't seem to be updating. I upgraded Python3.5 to Python3.7 just now. Deleted the old virtualenv (by deleting app/bin and creating a new virtualenv with virtualenv --python=/usr/bin/python3 . ) When in the virtualenv, if I do a python -V I get Python 3.7.7. If I run django-admin --version I see 3.0.6. But when I try to run the server, my Traceback says: File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/exception.py" in inner 41. response = get_response(request) So it's still pointing at apparently an old global install? How can I point it to the new version in the virtualenv I've created? -
Beginner Looking for Advice on How to Progress with Current Project
To combat a personal convenience issue and learn more about APIs, I made a python program that prompts a user for a YouTube playlist and transfers the songs from that playlist into a new or existing Spotify playlist (destination also prompted). I finally was able to get all the functionality working, but now I'd like to continue building the project, but I'm not really sure what to do next. Some things I'm interested in learning are building my own REST API and front and backend development, and wanted to incorporate that in this project by making a website where a user could log into their Youtube and Spotify accounts and complete the transfers in a more aesthetically pleasing interface as opposed to just running a python file. If anyone has advice on what would be best for a beginner to build next, and what technologies would be most relevant for front/back end, it would be greatly appreciated. Thanks! -

Django Blog - Comment function shows dropdown menu for authors in form
I created a Django Blog and want to add a comment section. So far I created the Comment-models and it is possible to make comments. But for every user it shows a dropdown menu where they can chose the user which will displayed with the comment-posting, which should not be. I tried to modifiy the Comments model and take out the 'author' in forms.py, but nothing works. Does anyone have an idea what I could do here? I assume it must have something to do with the author, I also tried 'author = models.ForeignKey(User, on_delete = models.CASCADE)' but same result.

Pointing Django storage to BunnyCDN
So I'm trying to serve /media/ files in a website through BunnyCDN, but I'm not exactly sure if I'm doing it right. From other remote storage implementations that I've seen, like AWS S3, I'm supposed to override the storage file that Django uses in my settings.py and do weird things to my urls file to point it to the server, but I'm kind of confused since the BunnyCDN documentation is very limited, and Django's own docs on writing custom storage systems are not very clear on this. I can't find anything since everyone seems to use AWS for this. -
Initializing manually rendered choice field on validation error
I've got a choice field that I'm manually rendering in my template. template.html <select name="pricing" id="id_pricing"> <option value> Make a selection </option> {% for value, object in form.pricing.field.choices %} <option value="{{value}}" {% if form.pricing.initial == value %} selected {% endif %} > {{object}} </option> {% endfor %} </select> This works 100% with one exception. If there is a validation error that gets thrown on another field due to checks that I have in def clean(), on the reload of the page, the value that populates the choice field isn't the one that the user just selected prior to submitting the form. It's 'Make a selection'. Do you know how I can ensure that the value that populates the choice field on reload of page due to validation error is the one that the user selected? Thanks for your help! -
Django 3.0: Unable to get value in view of selected option in template
I am at beginner level in django. And, I am unable to get the value of user selected option in view. I have to apply some logic there. views.py def shop(request): if request.GET.get('featured'): featured_filter = request.GET.get('featured') print(featured_filter) #debugging purpose else: print("\n\nnone\n\n") #debugging purpose bookz = Book.objects.order_by('title') var = {'books': bookz, 'range': 10} return render(request, 'bookrepo/shop.html', context=var) shop.html <form action="{% url 'bookrepo:shop' %}" method="GET"> <select name="featured" class="custom-select-lg custom-select"> <option selected><h1>Filter</h1></option> <option value="pricelow">Low price</option> <option value="pricehigh">High price</option> <input type="submit" name="featured" value="Filter" /> </select> </form> These option things have nothing to do with models.

How do I add security requirements to the password of my Django custom user model?
I'd like to start saying that I'm a beginner to Django, and I've been following a pretty great tutorial so far from Corey Schafer. In the project Corey uses the default Django User model, but I didn't want the users to log in with their username so I decided to override this as the Django docs say at https://docs.djangoproject.com/en/3.0/topics/auth/customizing/. I updated my registration forms with the new models and everything works fine. I can log in, log out and register properly, but I noticed that the password requirements for registration are gone. Previously Django would check if my password was too similar to the rest of my data, and had a minimum length requirement. I would like to know if there is a way to restore this feature. Here is my code for users/models.py: from django.db import models from django.contrib.auth.models import BaseUserManager, AbstractBaseUser from PIL import Image class UserManager(BaseUserManager): def create_user(self, email, name, password=None): """ Creates and saves a User with the given email, date of birth and password. """ if not email: raise ValueError('Users must have an email address') user = self.model( email=self.normalize_email(email), name=name, ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, name, password=None): """ Creates and saves a … -
(Django) automatic record creation for checklist?
I would like the user to be able to select a checklist for a project, however I believe the connection needs to be between the project and a checklist's items, not the checklist itself. This is to allow for an additional boolean field to mark whether an item has been completed for a specific project. However I only want the user to select the checklist name - so how would I code the app to automatically create the appropriate junction_project_checks records upon selecting a checklist? project(models.Model): name = models.CharField(max_length=100) checklist = models.ManyToManyField(checklist) checklist(models.Model): name = models.CharField(max_length=100) checks = models.ManyToManyField(checks, through='junction_checklist_checks') checks(models.Model): name = models.CharField(max_length=100) body = models.TextField() junction_checklist_checks(models.Model): checklist_id = models.ForeignKey(checklist, on_delete=models.CASCADE) checks_id = models.ForeignKey(checks, on_delete=models.CASCADE) junction_project_checks(models.Model): checks_id = models.ForeignKey(checks, on_delete=models.CASCADE) project_id = models.ForeignKey(project, on_delete=models.CASCADE) checkbox = models.BooleanField(default=False) -
How to create a selection based (multiple apps) experiment task in Django?
I am working at an experiment design and want to ask about your opinion and the feasibility with Django. We want to simplify our online experiments (university) and want to create a platform for our researchers to select settings for an online task (Picture 1). These are existing apps like a chatbot. There are also different settings / treatments like the collection of badges. Based on the selection, a website with its selected content and one or more links are generated to send out to a test person (Picture 2). I have some questions about this: How can I display all apps/experiments on one homepage (Picture 1) and generate sites for the selection (Picture 2)? How can I generate unique links for the sites to send them out to probands? Is Django the right option? I now that some of these questions are more opinion-based and I appreciate every answer on that! -

The serializer field might be named incorrectly and not match any attribute or key on the QuerySet instance models.py class Box(models.Model): box = models.IntegerField() controller = models.ForeignKey(Controller, related_name='boxes', on_delete=models.CASCADE) def __str__(self): return str(self.box) class Client(models.Model): client = models.CharField(max_length=30) cpf = models.IntegerField() box = models.OneToOneField( Box, on_delete=models.CASCADE, primary_key=True ) def __str__(self): return self.client serializers.py class ClientSerializer(serializers.ModelSerializer): class Meta: model = Client fields = [ "id", "client", "cpf", "box", ] class BoxSerializer(serializers.ModelSerializer): class Meta: model = Box fields = [ "id", "box", "controller" ] views.py class ClientViewSet(viewsets.ModelViewSet): serializer_class = ClientSerializer queryset = Client.objects.all() def list(self, request, store_pk=None, locker_pk=None, controller_pk=None, box_pk=None): queryset = Client.objects.filter(box=box_pk, box__controller=controller_pk, box__controller__locker=locker_pk, box__controller__locker__store=store_pk) serializer = ClientSerializer(queryset, context={'request': request}) return Response(serializer.data) def retrieve(self, request, store_pk=None, locker_pk=None, controller_pk=None, box_pk=None): queryset = Client.objects.filter(box=box_pk, box__controller=controller_pk, box__controller__locker=locker_pk, box__controller__locker__store=store_pk) client = get_object_or_404(queryset) serializer = ClientSerializer(client, context={'request': request}) return Response(serializer.data) I'm trying to get the object client on lockers/1/controllers/1/boxes/1/client/ which is OneToOneField relations with boxes and It's in a nested router I already tried use decorator @action but yet didn't work Anyone know why it's not finding the correct object attribute -
Enable Django support in IntelliJ?
I saw this question, but it doesn't help. I just made a new project in IntelliJ, (Community 2020.1 EAP). This is a Linux OS (Mint 18.3). In the left-hand panel I chose "Python". When I have created it I go File --> Project structure. I click "Facets" in the left-hand panel. In the middle panel it says "No facets are configured" and under that "Detection".

Naturally I have tried …
