Wrong installed virtualenv
I wanted to intall virtualenv in CMD (Windows 11). Unfortunately it was downloaded in the place I did not want to install it (it was supposed to be installed on D but it was installed on C. Also the folder i was expecting to be created was not created. What should I do to completly get rid of it from my computer? That is what occured after typing "virtualenv django" in CMD (django is the name of the folder which was supposed to be created): created virtual environment CPython3.11.0.final.0-64 in 1709ms creator CPython3Windows(dest=D:\django, clear=False, no_vcs_ignore=False, global=False) seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=C:\Users\mmilk\AppData\Local\pypa\virtualenv) added seed packages: pip==22.3.1, setuptools==65.6.3, wheel==0.38.4 activators BashActivator,BatchActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivator I chose the folder I wanted to install the program typed "virtualenv django". Later on the program introduced me where is the whole data which was created. It was on C instead of D. Is it true if I turn off the computer the virtualenv gets deactivated? Can I download it once again but this time on the completly different drive? For example the wrong virtualenv on C, the correct virtualenv on D. I'd only work on the virtualenv on the D drive. -
Django Polls Tutorial No answer detected in choice.votes polls
I decided to learn Django and started with the 'Django Polls App' which I figured would be the most simple, I am gripping the idea of how it works but I am stuck. To learn a bit better, I changed the variables and names from the original docs to my own. Example : question_text = q_text, Choice = Choices, choice_text = choice.. etc. Now I can't figure out what's wrong with my code as I can't make the polls work. There is no error code but it simply doesn't display the number of votes or show a success sign. I was also following Traversy Media's Django Crash Course (Polls App). My code : views.py from django.http import Http404, HttpResponseRedirect from django.shortcuts import render, get_object_or_404 from django.urls import reverse from django.template import loader from .models import Question, Choices def index(request): latest_ques = Question.objects.order_by('-published')[:5] context = {'latest_ques': latest_ques} return render(request, 'polls/index.html', context) def detail(request, question_id): try: question = Question.objects.get(pk=question_id) except Question.DoesNotExist: raise Http404("Question does not exist") return render(request, 'polls/detail.html', {'question': question}) def results(request, question_id): question = get_object_or_404(Question, pk=question_id) return render(request, 'polls/results.html', {'question': question}) def vote(request, question_id): question = get_object_or_404(Question, pk=question_id) try: selected_choice = question.choices_set.get(pk=request.POST['choices']) except (KeyError, Choices.DoesNotExist): return render(request, 'polls/detail.html', { 'question': … -

How do I put django cms plugins classes inside multiple files instead of just putting it all inside cms_plugins.py?
So I have a project where I am using Django CMS as the root of my project. First of all I'm new to Django CMS, and I now want to code some plugins to put into my pages. I searched for the solution but everywhere it says that I should put it inside cms_plugins.py. I tried creating a folder named cms_plugins and created an __init__.py file inside it. Then I created the plugin inside a file named ThePlugin.py and coded my plugin the same way I did it in cms_plugins.py. Unfortunately it's not working. If someone can help me I'd be really gratefull. Thanks. -
Is Django only good for web applications where a user logs in? [closed]
Is Django only good for web applications where a user logs in? The reason I ask is because I recently learned Django and built a website where a user could sign up, input their measurements, and the website tells them how many calories they should eat. Is there a way to build this website in a way where the user doesn't need to sign up or log in? I've seen Javascript-based exampled where data is carried from page to page using cookies but using Python / Django the only way I know how to do this is by using a database. -
How to generate newsfeed / timeline consisting of different types of contents?
I have to implement a newsfeed for an application where I need to show different types of content. And in the future, some new types of content may come. I have the following idea in my mind at a high level. At this point of time, I'm not concerned about ranking, caching, etc. My focus is to generate newsfeeds having different types of content. class ContentType1(models.Model): pass class ContentType2(models.Model): pass class ContentType3(models.Model): pass class Content(models.Model): c_type = models.CharField( max_length=6, choices=[ ('TYPE1', 'Type 1 content'), ('TYPE2', 'Type 2 content'), ('TYPE3', 'Type 3 content') ] ) type_1 = models.ForeignKey(ContentType1, null=True, blank=True) type_2 = models.ForeignKey(ContentType2, null=True, blank=True) type_3 = models.ForeignKey(ContentType3, null=True, blank=True) The idea is to have a general Content model having separate fields for every type of content and a field named c_type which determines the type of the content and guides to access the corresponding field. And responding to users' requests from the Content queryset. I'm not fully satisfied with the approach, looking for a better approach maybe something with polymorphism or any better approach using Django. -

Check box field in django forms showing error
Based on my django project I want to add multiple users to a group and I'm trying to do this using a form. But when I try adding choices via CheckBoxSelectMultiple() widget its not working as expected. models.py file from django.db import models from members.models import User from django.contrib.auth.models import Group class Sprint(models.Model): status_choice = [('Working','Working'), ('Closed','Closed')] sprint_name = models.CharField(max_length=180) sprint_created = models.DateTimeField(auto_now= True) lead = models.ForeignKey(User, on_delete=models.CASCADE, related_name='team_lead') sprint_members = models.ForeignKey(Group, on_delete=models.CASCADE, related_name = "member") sprint_period = models.PositiveIntegerField() sprint_status = models.CharField(max_length=10, choices=status_choice, default='Working') forms.py file from django import forms from .models import Sprint from members.models import User from django.core.exceptions import ValidationError from django.contrib.auth.models import Group class SprintForm(forms.Form): sprint_name = forms.CharField() sprint_period = forms.IntegerField(label="Sprint period (in days)", min_value=7) lead = forms.ModelChoiceField(queryset= User.objects.filter(role = 'Developer'), label="Team Lead") sprint_members = forms.ModelChoiceField(queryset= User.objects.filter(role = 'Developer'), widget= forms.CheckboxSelectMultiple(), label="Team members") # class Meta: # model = Sprint # fields = ['sprint_name', 'lead', 'sprint_period', 'sprint_members'] def clean(self): cleaned_data = super().clean() lead = cleaned_data.get('lead') team = cleaned_data.get('sprint_members') if team and lead: if lead in team: raise ValidationError('Team lead cant be in team') def save(self): team = Group.objects.get_or_create(name=f'team{self.cleaned_data["sprint_name"]}')[0] for team_member in self.cleaned_data['sprint_members']: team.user_set.add(team_member) Sprint.objects.update_or_create( sprint_name=self.cleaned_data["sprint_name"], lead=self.cleaned_data["lead"], sprint_period=self.cleaned_data["sprint_period"], _members=team ) views.py file class SprintCreationView(generic.FormView): model = Sprint template_name … -
WebSocket dosn't work with postman (django channels)
I have a Django project which I run locally on my mac. And I use channels to create websocket connection. And an interesting thing happened: The web socket works when I try to connect through .html file: myTemplate.html const ws = new WebSocket( 'ws://' + window.location.host +'/ws/test/?token=' +'**mytoken**' );' I can send, and receive messages. But the same URL doesn't work in postman or https://websocketking.com/ Firstly, I thought it is because I run server locally. But on real server nothing works at all.
