Django social network application - which machine learning model should I use and how to store it?
I am writing a Django project for a social network application. I need to create a machine learning model that - using existing data on a user's hobbies, interactions with content, current friends, etc - predicts the top 20 users to be matched. Which is the best model type to use for this situation? I thought about creating a model for each user but would that be optimal? How can I generalize the model to fit as many users as possible? Should I store the model on file or as part of the models.py in my Django project? -

Multiple Objects Returned. Django AllAuth
I am trying to get GitHub sign up option setup. But it keeps returning multiple objects. What I've learned until now is that there must be 2 entries in the social apps in Django admin. I checked and there is only 1. MultipleObjectsReturned at / No exception message supplied Request Method: GET Request URL: http://127.0.0.1:8000/ Django Version: 4.0.10 Exception Type: MultipleObjectsReturned Exception Location: /usr/local/lib/python3.11/site- I have setup everything correctly in settings.py. I don't think that is causing the issue. <li class="nav-item"> <a href="{% provider_login_url 'github' %}">Git</a> </li> This in the template is causing the error. -
Django user_id from django db missing in application models.py
A few Days ago I started this tutorial on Django: https://www.youtube.com/watch?v=sm1mokevMWk The video is about how to set up your first django project, using some libraries from django, as well as bootstrap to style your website. He goes on about how to setup the database, website and everything else you need for the example of a todolist website and at the end of the video series he goes over setting up Users, as well as user specific todo lists. I tried recreating the process and up to the point of the user specific todo lists it was all very understandable and easy to follow. Yet as I tried implementing pretty much the last step of the implementation i get the following error: OperationalError at /create/ table main_todolist has no column named user_id Request Method: POST Request URL: http://127.0.0.1:8000/create/ Django Version: 5.0.1 Exception Type: OperationalError Exception Value: table main_todolist has no column named user_id Exception Location: C:\Entwicklung\Python\Python312\Lib\site-packages\django\db\backends\sqlite3\base.py, line 328, in execute Raised during: main.views.create Python Executable: C:\Entwicklung\Python\Python312\python.exe Python Version: 3.12.0 Python Path: ['C:\Users\brenneckeo\Desktop\Django Projekt\meineSeite', 'C:\Entwicklung\Python\Python312\python312.zip', 'C:\Entwicklung\Python\Python312\DLLs', 'C:\Entwicklung\Python\Python312\Lib', 'C:\Entwicklung\Python\Python312', 'C:\Entwicklung\Python\Python312\Lib\site-packages'] Server time: Wed, 28 Feb 2024 14:18:52 +0000 The Error pops up when I try to create a ToDoList.

I am building an Ecommerce site thru Django framework. While creating category section which takes user to individual category to access all its items, following error occurs.

Django/Python - Delete function in UpdateView is duplicating rather than deleting
i have created a Django app that allows users to enter their stock trades, as a journaling tool. When a user clicks on an individual journal entry from the index page, they will be taken to a detail page showing all the information on that individual entry (single_entry.html). This page is handled by an UpdateView. From this page, a user can edit/update any info, as well as DELETE that specific entry. To accomplish this, I've imported the DeletionMixin module from django.views.generic.edit. However, when I click on the "Delete" button in the form, the entry is duplicated instead of deleted! Does anyone know why that's happening?? Thanks for your help! Here's my class based view in views.py: class SingleEntryView(UpdateView): template_name = "single_entry.html" model = Entry fields = ['ticker', 'strategy', 'result', 'comments', 'image'] success_url = '/' def post(self, request, *args, **kwargs): if "delete_button" in self.request.POST: return self.delete(request, *args, **kwargs) def update_post(self, form, pk): if "update_button" in self.request.POST: form.instance.user = self.request.user return super(SingleEntryView, self).update_post(form) single_entry.html: {% extends 'base.html' %} {% block title %} Trading Journal - Entry {% endblock title %}Trading Journal {% block content %} <form method="POST" action="/"> {% csrf_token %} {% for field in form %} {{field.label_tag}} {{field}} {% if field.errors … -
Summenote doesn't send data values in nested fields
I'm trying to create nested fields with htmx and summernote: When the user clicks in the button "Adicionar nova alternativa" it returns another section. <button class="button is-info" hx-get="{% url 'create_alternativa' espaco=espaco.title %}" hx-target='#alternativas_criadas' hx-trigger="click" name="alternativa" hx-swap="beforeend" > <span class="icon is-small"> <i class="fa-solid fa-circle-plus" ></i> </span> <p>Adicionar nova alternativa</p></button> the problem is that summernotes dosen't send the text values. <div class="column is-9"> {% render_field form_alternativa.text style="height:291px;" %} </div> views.py if request.method == 'POST': print(request.POST) the print result for the same input as in the image when i try to submit the form: <QueryDict:{'text': ['<p>Test1</p>', '', '']}> The problem doesn't happen when I don't use summernote. When I use just a 'textarea', the form is submitted properly. Thanks! -
Django with Freenom [closed]
I just got started on Django and web development (i love it so far). I have gotten far enough to start considering deployment options. Getting a domain name for free is always a challenge. I have been using Heroku for quite sometime now but they put up some limits to it that has become a blocking stone. So I did a "little" research and found out that i could get a domain name for free on freenom.com that should last for a year. But then i could not figure out a way to connect that domain name to a Django project. How would I host the project files? Is there a better option that I can check out? I wanted to see if i could somehow connect my free domain at freenom.com and a django project i created. -
Making a post request to a Django app on MS Azure from a client that I do not own getting cors error
I have deployed a django app on azure and have been running it for a while. I recently added an endpoint to my app that should get a POST request from the jengahq website. However, I am able to simulate post requests from them to my endpoint and see the responses. Everytime I simulate my POST request, I get an error: Access to fetch at https://notification-webservice.azurewebsites.net/... from origin jengahq site has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource... However, I have enabled cors-origin for this website. It also requires a basic authentication header which I have added appropriately as shown below: CSRF_TRUSTED_ORIGINS = ( ["https://" + os.environ["WEBSITE_HOSTNAME"], "https://secondsite", ]) CORS_ALLOWED_ORIGINS = [ "https://" + os.environ["WEBSITE_HOSTNAME"], "https://secondsite", ] CORS_ALLOWED_HEADERS = [ 'Accept', 'Accept-Encoding', 'Authorization', ... ] The first website in my cors allowed is where my frontend is served and I am able to run requests well. This does not work for the second website. When I remove my frontend site from my cors allowed list, I get a similar error, but the endpoint seems different: Access to fetch at mysite from origin myfrontend has been blocked by CORS policy... Even with the addition … -

127.0.0.1 slowness in django virtual environment running with vscode
After connecting to the server built in awsec2 with a remote of vscode, the django virtual environment was run to make a connection of 127.0.0.1. But its speed is too slow. When you connect using Chrome, the loading is too slow, sometimes it's infinitely loaded, and sometimes there's content that hasn't been loaded even if it's marked. There are even cases where only white pages are displayed. I'm currently using a MAC. Using a Windows laptop, connecting remotely to a remote server using vcode and then connecting to 127.0.0.1 will work fine I've been looking for other posts, but none of them correspond to my issues. I've tried many things. Turn off the process that currently uses 8000 ports on the Mac (but it was not there) Connect django to 8888 port or unused port and view it (this is the same error as well) It used to work very well, but it doesn't work well at some point. What should I do? -
