How can i load all fixtures inside particular directory While writing TestCases in Djnago using Pytest
I have multiple fixtures(json files) inside admin folder and i need to load all the fixtures of that directory without mannuallly writing all fixtures location. I have tried below code but but it's not working @pytest.fixture(scope='session') def load_admin_data(django_db_setup, django_db_blocker): fixtures = [ 'fixtures_for_tests/admin/*.json' ] with django_db_blocker.unblock(): call_command('loaddata', *fixtures) I need to give each and every fixture's location like shown below: @pytest.fixture(scope='session') def load_admin_data(django_db_setup, django_db_blocker): fixtures = [ 'fixtures_for_tests/admin/data1.json', 'fixtures_for_tests/admin/data2.json', ] with django_db_blocker.unblock(): call_command('loaddata', *fixtures) Note: One approch which i figure out is get all fixture location using some script is there any other way to give fixture location using some regex pattern while loaddata? I'm expecting that i'm able to give dyanamic path or regex pattern of fixture location -

Django allauth google login with Google identity
The google sign in javascript library is being deprecated: Warning: The Google Sign-In JavaScript platform library for Web is deprecated, and unavailable for download after March 31, 2023. The solutions in this guide are based on this library and therefore also deprecated. Use instead the new Google Identity Services for Web solution to quickly and easily sign users into your app using their Google accounts. By default, new client IDs are now blocked from using the older platform library; existing client IDs are unaffected. New client IDs created before July 29th, 2022 may set the plugin_name to enable use of the legacy Google platform library. The existing oauth implementation from django-allauth requires the users to either use server-based redirect with the Oauth2.0 code or send in both the access_token and id_token for processing the login, The implementation by google now only gives us the id_token and all the required data like name, profile picture etc. is included in the JWT token. Thus, the login fails as I am unable to send in both the access token and the id token. There are two approaches that come to my mind for solving this: I either override the social login view and … -

I have django model ImageField called avatar. I want to enable user clear their avatar, so Blank = True. The problem is when user clear their avatar, the ImageField path is now empty. What i want is, the ImageField back to default. models.py class Profile(models.Model): AVATAR_UPLOAD_TO = "account_avatar/" DEFAULT_AVATAR = "default.jpg" user = models.OneToOneField(CustomUser, on_delete=models.CASCADE) avatar = sorl.thumbnail.ImageField(upload_to=AVATAR_UPLOAD_TO, default=AVATAR_UPLOAD_TO+DEFAULT_AVATAR, blank=True, null=True) I see some related questions Django ImageField overwrites existing path when empty.

Share env across GitHub Actions workflows
I have a GitHub Action (test-python.yml) intended to test a Django application. It utilizes the env tag like so towards the top of the file: env: SECRET_KEY: test DEBUG: False ... I want to make another workflow - not a job in the same workflow - that is reliant on the same variables. I could obviously just make another file for said workflow and copy the env however this seems slightly flaky, I'd rather somehow share the env variables across numerous workflows so I only have to keep it up to date in one place. Is there a way to do this? Thank you in advance! -

What is the best way to parse this request.data in drf, when the request is form-data?
I have this form which sends an image along with some other data. I am using django-rest-framework in the back end. I need to take out couple of fields from this form input and do some operations and use the remaining fields to send to my ModelSerializer for posting the form data. What is the best way to achieve this? <QueryDict: {'areaName': ['Mall-24F'], 'devices': ['[\n {\n "name": "device_001",\n "coordinates": [\n 23,\n 56\n ],\n },\n {\n "name": "device_002",\n "coordinates": [\n 24,\n 57\n ],\n },\n {\n "name": "device_003",\n "coordinates": [\n 25,\n 58\n ],\n }\n]'], 'floorMap': [<InMemoryUploadedFile: 1653650801973.png (image/png)>]}> This is how request.data looks like. What I have tried doing is context = request.data context["name"] = context.pop("areaName")[0] context["floor_map"] = context.pop("floorMap")[0] Basically I only want "name" and "floor_map" to be sent to ModelSerializer. I have read that request.data is immutable, but here it is mutable. I think I am missing something. -

Django simplejwt validate token
I am implementing authentication with Django simpleJwt, and have a question. I want to create something with Client's jwt token. I use methods provided from simpleJwt to validate and decode jwt token. class AccountBookAPIView(APIView): def post(self, request): jwt_authenticator = JWTAuthentication() raw_access_token = request.META.get('access_token') validated_token = jwt_authenticator.get_validated_token(raw_access_token) user = jwt_authenticator.get_user(validated_token) However, I doubt that some methods really validate token.

Creating a simple multiple users app in Django
So I've created 3 different users: admins, developers, and project managers. When I use the individual signup forms for each of these users and log out, it works, but then I when try to use the login form, it seems to me that it's acting like the signup form. Because when I input the same user details as the one I just created into the login form, it throws up the built-in error message, 'A user with that user name already exists' I'm not sure how to proceed from here. Here's what I have so far. models.py class CustomUser(AbstractUser): ACCOUNT_TYPE_CHOICES = ( ('admin', 'Admin'), ('developer', 'Developer'), ('project_manager', 'Project Manager') ) account_type = models.CharField(max_length=20, choices=ACCOUNT_TYPE_CHOICES) login and signupviews class LoginView(View): def get(self, request): # Render the login form form = LoginForm() return render(request, 'users/login.html', {'form': form}) def post(self, request): # Get the form data from the request form = LoginForm(request.POST) # Validate the form data if form.is_valid(): # Get the username and password from the form username = form.cleaned_data['username'] password = form.cleaned_data['password'] # Authenticate the user user = authenticate(request, username=username, password=password) # If the user is authenticated, log them in and redirect to the homepage if user is not None: login(request, …
