AttributeError 'str' object has no attribute 'add'
I am working on a project which has multiple types of users. Such as students, teachers, staff, etc, I use Django AbstractBaseUser to define my own fields. Problem: At the time that I save a user as a student; in addition to email and password, I also want to save some more information about the student user, such as profile info. The same pattern should be applied to other types of users as well.

Graphene Subscription error (has no attribute 'execute')
I am trying to make subscriptions work in my Django application. I have have followed the tutorial on the apollo client subscriptions part (https://www.apollographql.com/docs/react/data/subscriptions/): For the backend I have used this plugin (https://pypi.org/project/graphene-subscriptions/) and followed the instructions step by step as well, installing Django channels and setting the channel layers adding the query in the schema etc. However, I get an error when I try to 'do' the subscription and I believe it's a more general problem than one caused by the plugin I used. I was hoping one of you might have an idea what I did wrong. This is some of the relevant code: const httpLink = new HttpLink({ uri: "http://localhost:8000/graphql/", // use https for secure endpoint }); // Create a WebSocket link: const wsLink = new WebSocketLink({ uri: "ws://localhost:8000/graphql/", // use wss for a secure endpoint options: { reconnect: true } }); // using the ability to split links, you can send data to each link // depending on what kind of operation is being sent const link = split( // split based on operation type ({ query }) => { const { kind, operation } = getMainDefinition(query); return kind === 'OperationDefinition' && operation === 'subscription'; }, … -
Custom Id in Django Models
In my model I need an ID field that is different from the default ID given by Django. I need my IDs in the following format: [year][ascending number] Example: 2021001,2021002,2021003 The IDs shall not be editable but model entries shall take the year for the ID from a DateTimeField in the model. I am unsure if I use a normal Django ID and also create some kind of additional ID for the model or if I replace the normal Django ID with a Custom ID. -

Tagulous - Getting AutoComplete Fields to work
I have installed Tagulous successfully in to my Django app, and I have created a Tag textfield although, I'm struggling to get the AutoComplete process to work. I have been referencing the Tagulous instructions. I have installed AutoComplete and have included the relevant JS and CSS libraries within my Settings.py. Along with ensuring that "dal" and "dal_select2" is installed under INSTALLED_APPS. When I go to my form, I'm not receiving any errors and the Skills tag field appears. Although, there is no sign of any autocompletion working, the field just currently behaves as a regular tag field without the autocomplete feature. Here's my code so far: Views.py - (I have imported from dal import autocomplete in to this file) class PostCreateView(LoginRequiredMixin, CreateView): model = Post fields = ['content', 'image', 'skills'] widgets = { 'skills': autocomplete.ModelSelect2(url='skills-autocomplete') } template_name = 'sfsrv/post_new.html' success_url = '/' def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def get_context_data(self, **kwargs): data = super().get_context_data(**kwargs) data['tag_line'] = 'Create new post' return data class SkillsAutocomplete(autocomplete.Select2QuerySetView): def get_queryset(self): # Don't forget to filter out results depending on the visitor ! if not self.request.user.is_authenticated(): return Skills.objects.none() qs = Skills.objects.all() if self.q: qs = qs.filter(name__istartswith=self.q) return qs URLs.py (I have imported from sfsrv.views … -

Python not decoding JSON because "encoding" is an unexpected argument
I have a Django 2.2.23 app, running on Python 3.9.4. I have django-extensions 2.2.9. I have a model that has a django_extensions.db.fields.json.JSONField attribute (which, AFAIK, is just a text field auto-serialized). I mention this because when the JSON is deserialized, the django-extensions library does it like this: def loads(txt): value = json.loads( txt, encoding=settings.DEFAULT_CHARSET ) return value The problem is that the library imported by import json gives me an error when it's called this way: Python 3.9.4 (default, Apr 5 2021, 01:50:46) [Clang 12.0.0 (clang-1200.0.32.29)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import json >>> json.loads("{}", encoding="UTF-8") Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/Cellar/python@3.9/3.9.4/Frameworks/Python.framework/Versions/3.9/lib/python3.9/json/__init__.py", line 359, in loads return cls(**kw).decode(s) TypeError: __init__() got an unexpected keyword argument 'encoding' >>> The end result is that I am unable to load any of the records that contain a JSONField from the database because the JSONDecoder can't handle being passed an encoding argument.

Setting blank = False for email field in django authentication
I am using django built-in authentication and for that authetication system, we are given different fields like username, email, password etc. Username by default is required and also not blank but for email it is not required (i.e, it is null) which makes it blank also. Now for making it required, i added this code; extra_kwags = {'email': {'required': True}} I tried the same with blank; extra_kwags = {'email': {'required': True, 'blank': False}} But it gives error saying blank is not a valid keyword there. So i want to know if there is a way to set blank=False for the email field in django. Though i know a way which is by making the email_verification mandatory and making email the way to autheticate; ACCOUNT_AUTHENTICATION_METHOD = 'email' ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_EMAIL_VERIFICATION = 'mandatory' But i want to know if there is another way as i don't want it to make authentication_method. -

Fetch data from django backend having parts of dynamic URL private
Let's say I am developing a django REST api that is secured via token and basic authentication. The idea is to list juices. So I am having an URL that lists all juices from specific brands. So I got a dynamic URL like: path("juices/<str:brand>/" ...) What I want to do now is to show all juices of the brand coca-cola in my frontend where no authentication is required. So all visitors should see the list of juices from coca-cola. I need to use JS fetch since it has to be asynch. Thus my code is something like: async function get_juices() { let juices = await fetch( `${hostname}/api/v1/juices/coca-cola/ ) result = await juices.json(); return juices; } My backend is a simple ListView that dynamically filters by brand. But my problem now is that the API is private and I can't use my credentials in my frontend for obvious security reasons. Because any user could just read the frontend code and use my credentials to access the juices of other brands too. I was reading now in some posts that it is possible to have a proxy server which only accepts requests from a specific client and reroutes the request with credentials … -
