Calling other docker container by name doesn't work when using Nginx (Docker, Django, React/Next.js)
I am working on a project with Docker using Django in the backend and Next.js in the front. I currently have it working without using Nginx by binding the ports of each container to the host machine's port 8000 and 3000 respectively, with the Next.js's serverside calling from environment variable set as 'backend:8000/users/auth_api/google/' for authentication (backend is the container name for the backend). However, upon including Nginx, it doesn't seem to work anymore. I had to include a '/backend/' prefix to my backend container with the proxy_pass setting as I intend for the root '/' to be for the frontend. I've tried setting different environment variables and verified that uri call from the serverside from the logs but it just doesn't reach the backend (logs show that the api call to the environment variable uri was made by the frontend but not received by the backend meaning the api uri is wrong). Environment variables I've tried: SS_BACKEND_GOOGLE_AUTH=http://0.0.0.0:8000/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://0.0.0.0:8000/backend/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://backend:8000/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://backend:8000/backend/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://backend/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://backend/backend/users/auth_api/google/ Docker-compose file version: '3.8' services: backend: restart: unless-stopped build: context: ./backend dockerfile: Dockerfile.test command: sh entrypoint.prod.sh container_name: backend expose: - 8000 ports: - 8000:8000 volumes: - ./backend/:/usr/src/backend/ - static_volume:/usr/src/backend/staticfiles - media_volume:/usr/src/backend/mediafiles env_file: - ./.env.test depends_on: - db - … -

whats the most sensible way of keeping the current user when using mobile auth on login?
I want mobile auth on login, but am wondering what the best way would be to store the current user, before giving them a session id (which would be granted on successful mobile auth). does it make sense to store a jwt in cookies for the user after they enter their password, while they're on the 2fa auth page? I've looked at a few sites with 2fa, and cant see any that do this, so figure there must be a better way? -
Django RecursionError on A2 Hosting server with basic project
I recently set up Python hosting for my Django application. I used A2Hosting with cPanel, and followed these instructions that they gave. So now I have a Django project and application, with a few modifications they asked for; I can confirm that the app is running, but… Now I'm doing the standard procedure, creating a simple HttpResponse view, creating an app-local urls.py, linking that urls.py to the project-wide urls.py, and removing this url block that they had me use, which WORKS, but I really don't want to render the templates raw like this: url(r'^$', TemplateView.as_view(template_name='static_pages/index.html'), name='home'), Well now I'm getting this error: (DOMAIN, APP, and USERNAME removed for privacy) RecursionError at / maximum recursion depth exceeded while calling a Python object Request Method: GET Request URL: http://APP.DOMAIN.TLD/ Django Version: 3.1.4 Exception Type: RecursionError Exception Value: maximum recursion depth exceeded while calling a Python object Exception Location: /home/USERNAME/virtualenv/APP/3.7/lib/python3.7/site-packages/django/urls/resolvers.py, line 258, in match Python Executable: /home/USERNAME/virtualenv/APP/3.7/bin/python Python Version: 3.7.8 Is my version too high?

Is there a way in Django Rest Framework to deliver only specific attributes?
When building a large web backend we are faced with the problem that we have models with a lot of attributes. As we want to reduce the size of the responses for efficiency we use different serializers for our models. Take this simple model for instance: class Address(models.Model): country_id = models.ForeignKey(Country, on_delete=models.PROTECT) postal_code = models.CharField(max_length=10) street = models.CharField(max_length=176) number = models.CharField(max_length=20) additional = models.CharField(max_length=256, blank=True, default='') city = models.CharField(max_length=176) state = models.CharField(max_length=50) user = models.ForeignKey('user.User', on_delete=models.CASCADE) For this alone we have an ID Serializer, a StringSerializer (for delivering a usable string), a MinimalSerializer (for a list of multiple addresses), a DetailSerializer (with depth=1 for getting country and user details ... Now with this complexity we face several issues and thought about restructuring the api to include the required fields in the request. Is this possible with django + drf? We believed to find something under Content Negotiation but this is a different topic. -
Django display uploading files in different fields
I am creating a system with Django. A user has several customers. And every customer has a different file upload field. I have upload functions but it is common for everyone. What I want is for every customer should have different pdf upload and display field. How can I do that? models.py class Pdf(models.Model): comp_name = models.CharField(max_length=200, default='', blank=True, null=True) title = models.CharField(max_length=200) pdf = models.FileField(upload_to='pdfs/') type = models.CharField(max_length=200, default='Select') year = models.CharField(max_length=200, default='Select') def __str__(self): return self.title views.py def pdf_list(request): pdfs = Pdf.objects.all() return render(request, 'pdf_list.html', {'pdfs': pdfs}) def upload_pdf(request): if request.method == 'POST': form = PdfForm(request.POST, request.FILES) if form.is_valid(): form.save() return redirect('pdf_list') else: form = PdfForm() return render(request, 'upload_pdf.html', {'form': form}) forms.py class PdfForm(forms.ModelForm): CHOICES = [ ('img', 'Image'), ('txt', 'Text'), ] type = forms.ChoiceField(choices=CHOICES, widget=forms.RadioSelect) year = forms.fields.DateField(widget=forms.widgets.DateInput(attrs={'type': 'date'})) comp_name = forms.ModelChoiceField(queryset=CompanyProfile.objects.all(), required=False, widget=forms.HiddenInput()) customer/model.py class Customer(models.Model): name = models.CharField(max_length=20) surname = models.CharField(max_length=20) companyName = models.CharField(max_length=200, default="Choose") -

Customising the template for a form widget.: Can other object properties be passed as attributes?
I have a model form that represents the choices for a ManyToMany field as checkboxes. The two related models are as follows: Passenger Model: class Passenger(models.Model): ... attributes etc ..... trip_addons = models.ManyToManyField(AddOn, blank=True) 'Add on' Model: class Addon(models.Model): name = models.CharField(max_length=254) description = models.TextField() price = models.DecimalField(max_digits=8, decimal_places=2) image = models.ImageField(null=True, blank=True) image_thumb = models.ImageField(null=True, blank=True) image_url = models.URLField(max_length=1024, null=True, blank=True) def __str__(self): return self.name But rather than rendering the default html checkboxes, I would like present the 'addon' options a little more like the 3rd example 'Choose your main dish' in this link, with the picture and short description in addition to the name. I have created my own template to be used by the widget and that works. I just would like to know if can pass the description, image and price data to these templates? forms.py class CustomCheckbox(forms.CheckboxSelectMultiple): """ Creates a custom checkbox select widget that subclasses Django's CheckboxSelectMultiple and customises it with a different template """ template_name = 'bookings/forms/checkbox_select.html' option_template_name = 'bookings/forms/checkbox_option.html'. and in the Meta for my Modelform: widgets = { "trip_addons": CustomCheckbox(), } -
Which is the best way to protect a Django API?
I've deployed a Django API powered with Django Rest Framework with some open endpoints and some Authenticated endpoints using Token authentication. Which is the best way to protect the entry API allowing only to send request from the app frontend team? I was thinking to use an Nginx basic auth, but then the Authorization header is duplicated, so Token auth is not working. -
