Django: How to make one-to-one relation with auth login and custom profile model?
I've implemented google login to my project, logs in correctly and makes a new row in the database for the user, but does not make a profile. I have one-to-one relation between the user and the profile, how can i add profile for the google logins? I'm getting error UserProfile matching query does not exist. when i try to view my profile on the page. This is the view for the profile page: class ProfileView(views.View): template_name = 'profile/profile.html' def get(self, request, pk): user = UserModel.objects.filter(pk=pk).get() profile = UserProfile.objects.filter(user_id=user.pk).get() context = { 'profile': profile } return render(request, self.template_name, context) the url: path('profile/<int:pk>/', views.ProfileView.as_view(), name='profile-page'), and the template: <li class='text-black text-xl mx-2 py-1.5 rounded-full bg-slate-300 shadow-2xl hover:bg-slate-400'> <a class="px-3 py-1.5" href="{% url 'profile-page' pk=request.user.pk %}"> <i class="fa-solid fa-user"> </i> </a> </li> I can get the error not to show but when i try to edit the profile it cannot do it since it has no relation with the profile model. -
Is it possible to get max id in filtered and limited queryset without fetching?
Suppose I have a table in db with rows like this: ID Foo 19 1 20 1 38 2 44 1 50 2 61 1 I want to get max id (50 in this example) from queryset like this: MyModel.objects.filter(foo=2).values_list('id')[:limit] limit, of course, can be greater than total row number. I can do this by fetching all queryset, convert it to list and use the last item list(MyModel.objects.filter(foo=2).values_list('id')[:limit])[-1] but can I do this in database, without fetching entire queryset? Raw sql solution is welcome too. DB is PostgreSQL. -

WSGI Server for Django + Python-Socketio
I have a Django server, that also has a socketio compenent using python-socketio library. I'm trying to produce a relatively simple but production ready deployment for it on an Amazon EC2 Instance. I've successfully configured the NGINX proxy. I'm curious about the best way to deploy, specifically with regard to WSGI. I've tried using the raw eventlet WSGI server (eventlet.wsgi.server(eventlet.listen(("", 8000)), application)). I then start it with python manage.py runserver. This has worked okay, but I'm unsure about how scalable it is. It seems like the standard stack is Django + Gunicorn + NGINX. Based on python-socketio documentation, this should be possible. I tried django + eventlet + gunicorn, but it seems like gunicorn a) doesn't play nice with eventlet and b) only supports one worker. Gevent + Gunicorn doesn't have this bug, but still only supports one worker. Also, I'm not sure how actively maintained gevent is. So I'm not sure how scalable either Gunicorn + eventlet or Gunicorn + geventlet is as a WSGI server. So I'm not sure if Gunicorn is my best bet, or if it's too limited. So TL;DR a) what scalable stack have you experienced success with for deploying Django + python-socketio and b) … -
Django Model with several OneToOne relationships of same model: implementation strategy
i am looking for a solution to the following problem: i defined the following class: class Parameter(models.Model): name = models.CharField(max_length=40) value = models.FloatField() unit = models.CharField(max_length=20) it describes a parameter for a measurement. now, i have various specific measurement classes and in these classes i want to define a couple of specific parameters as well as custom parameters class SpecificMeasurement1(models.Model): ... some fields here.... specific_parameter_1 = models.OneToOneField( Parameter, on_delete=models.CASCADE, related_name='specific_measurement_1_param_1') specific_parameter_2 = models.OneToOneField( Parameter, on_delete=models.CASCADE, related_name='specific_measurement_1_param_2') now i have several questions: does it make sense to implement the specific parameters like that? in the example above i define the One-To-One relationship in the parent class, which generally is not the best practice? however, i dont have another idea. For the specific parameters, is it possible to fix the name-field in the Parameter-object? e.g. to 'specific_parameter_1' for the specific_parameter_1. how / where would i define any custom-parameters? imagine a user wanted to add some additional parameters to their measurements with custom names. would i include a Generic Relationship in the Parameter class? in that case it can be included in any SpecificMeasurementX class? thanks for your opinions. Kind regards -
Django RestFramework Redirect failing
I am trying to build a csv file using POST and redirecting to GET to download that file. I tried returning a FileResponse/HttpResponse in the post function but the file doesnt download. But when I do a GET, it downloads the file and doesn't allow to take an input.

How to display automatically value instead of key in django rest framework for a model attributs which a choice fields?
I have a DRF api with model attributs with choice field like this: STRONG_FOOT = ( ("N", "-"), ("R", "Right"), ("L", "Left"), ("B", "Both") ) class Player(models.Model): ... strong_foot = models.CharField(max_length=2, choices=STRING_FOOT) ... I can chose to display the value instead of the key of the choices like this in my serializers: class JoueurSerializer(serializers.ModelSerializer): ... strong_foot = serializers.CharField(source="get_strong_foot_display") ... class Meta: model = Player fields = "__all__" The issue I have is that I have more than 30 attributs in my models. Is there a way to ask DRF to show automatically the value instead of the key of the choice field in the list view ? Or do I need to do what I did in the serializers for all of my attributs ? -

Authenticate works but login does not. It's stuck on pending

I am able to create and authenticate users through forms or the cli but once the user/patient object is passed to the login(request, user) function, the entire application gets stuck and the pages keep loading. Whether I am logging in directly from the sign in page or registering a new member then trying to redirect them based on successful authentication. What could the issue be?

best methods of archiving data of a model in django
Hello everyone, I have a Django model says modelA with 10 million records, our team took a call to not show the first million records as that data would not be of any interest to our customers and data is very old. Now I have two options. Option 1. Don't archive any data, just add created_date param in the search query in such a way that first 1 million records get filtered out while searching against the modelA. Option 2. Archive the first 1 million records of modelA, so that we don't add any date any created_date param in the search query. Can someone tell me please if option is very efficient. Note1: This model has references to other tables, so if I took a call to archive the data, I need to archive the referenced tables as well. -
