no such table: two_factor_phonedevice when using django-two-factor-auth==1.14.0 and --nomigrations
I have a 2.2 Django project with django-otp==0.8.0, django-two-factor-auth[phonenumbers]==1.14.0, and an app two_factor_auth that makes use of these two libraries.

Django filter by date gives wrong results
I am trying to filter data retrieved from a postgresSQL table using django filter method. Below is the code I am using for that and I am giving "2022-7-13" as the filter_date in the query. The database has 62 entries for the date "2022-7-13" but, the API gives 23 as the result.

Why isn't the current directory in sys.path for a django application
To my understanding, the sys.path has the current directory (the directory the module is in) as its first index, yet this seems inconsistent with django. I have a project structure: In my_file_1.py, printing sys.path gives me: In my_file_2.py, printing sys.path gives me: These two sys.path prints makes sense since that red underline is the directory the modules are in (their respective current directory). However, in my django app with the following project structure: When printing sys.path in urls.py, I get: Which is the root directory of the project, instead of the current directory of urls.py which should be c:\\Users\\5403\\Desktop\\tutorial\\tutorial Could someone explain this inconsistency and correct me if I have any misconceptions, thanks. -

for loop in django template returning blank list items
I'm looping through the field of joined for my Group model and returning the list of joined members in my GroupDetail template: class Group(models.Model): leader = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=55) description = models.TextField() joined = models.ManyToManyField(User, blank=True) Each member in the for loop relates to a User (or username) that has joined the Group: <ul> {% for member in joined_members %} <li>{{ member }}<li> {% endfor %} </ul> There are four members in the Group, and all members are being returned, however four empty list items are also being returned as such (via chrome dev tools): <ul style="display: block;"> <li>joe</li> <li></li> <li>johnny</li> <li></li> <li>ralph</li> <li>/li> <li>mike</li> <li></li> </ul> There are only four members (Users) joined to this particular group, so I don't understand what's happening. I assume the issue is from how I passed the data into the template from my view: class GroupDetail(DetailView): model = Group template_name = 'group_details.html' def get_context_data(self, *args, **kwargs): group = get_object_or_404(Group, id=self.kwargs['pk']) joined_members = group.joined.all() context = super(GroupDetail, self).get_context_data() context["joined_members"] = joined_members return context There are no actual errors, just these four empty list items. Is the issue with my for loop? Or is it with how I'm passing my context? -

Fixing load static Django Templates
I've been searching for an answer to this and I feel like I'm doing everything right and have taken on suggestions in multiple posts but this is still stumping me. I'm trying to load static in my django template but for some reason I keep getting and unresolved template error and it won't load in my browser. project/settings.py # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/4.0/howto/static-files/ STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' STATIC_FILES_FIRS = [os.path.join(BASE_DIR, 'static')] I've set up the static root. Then in my base.html I've got: {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <link rel="icon" type="image/png" sizes="16x16" href="{% static "favicon/favicon.png" %}"> <title>Title</title> <script src="https://cdn.tailwindcss.com"></script> </head> <body> {% include "navbar.html" %} <img src="{% static "favicon/favicon.png" %}" alt="img"/> <main class="container mx-auto p-8"> {% block main %}{% endblock %} </main> </body> </html> I feel like I'm missing something because that directory should exist but the django template isn't finding it! I've tried using {% load staticfiles %} instead but that errors saying it can't find staticfiles. Any help would be appreciated! Thanks, Mitchell -

How do I update settings.py using views and forms in Django? [duplicate]
I want to set my variables in settings.py through the front-end using Views and Forms. Let's say, I have following in settings.py: # My personal settings NO_OF_DAYS = 0 and I have following in my forms.py: def class SettingsForm(froms.Form): no_of_days = forms.CharField(max_length=254) Now, I want mixture of views and forms, something like below in my views.py: from django.conf import settings from .forms import SettingsForm class UpdateSettings(View): def get(self, request): settings_form = SettingsForm() return render(request, "settings-template.html", "form": settings_form) def post(self, request): settings_form = SettingsForm(request.POST) if settings_form.is_valid(): form_data = settings_form.cleaned_data settings.NO_OF_DAYS = int(form_data["no_of_days"]) # I WANT SOMETHING LIKE THIS, BUT I WANT SETTINGS.PY TO STORE THE VALUE FOREVER, NOT JUST IN THIS VIEW return redirect("/success/") How do I accomplish it?
