URLconf does not appear to have any patterns in it/Circular import error
I am following a tutorial found in the Django documentation and upon attempting to map a view to a URL I received the following error: raise ImproperlyConfigured(msg.format(name=self.urlconf_name)) django.core.exceptions.ImproperlyConfigured: The included URLconf 'pollSite.urls' d oes not appear to have any patterns in it. If you see valid patterns in the file th en the issue is probably caused by a circular import . I have a pollSite project and a poll app. pollSite/pollSite/urls.py: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('polls/', include('polls.urls')), ] pollSite/poll: from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), ] views.py: from django.shortcuts import render from django.http import HttpResponse def index(request): return HttpResponse("Hello, world") I thought I may have mistyped something so I went back and copied the code from the docs and pasted it directly into my editor and still got the same error. I'm not sure what a circular import is but I am also working with virtualenv for the first time and am not sure if that could be causing this. Any suggestions?

Cannot test session params within Django test
I have home template that shows the message if it's provided: base.html <main role="main"> <div class="container"> {% if message %} <br> <span class="text-success">{{ message }}</span> <br><br> {% endif %} {% block content %} {% endblock %} </div> </main> home.html {% extends 'base.html' %} {% block content %} <span>Hello</span> {% endblock %} views.py def home(request): params = {} if 'message' in request.session and request.session['message']: params['message'] = request.session['message'] del request.session['message'] return render(request, 'products/home.html', params) And test for this code that I cannot make work: class HomeTests(TestCase): def test_home_shows_message_if_session_param_is_provided(self): self.client.session['message'] = 'test' self.client.session.save() response = self.client.get(reverse('home')) self.assertEqual(response.status_code, 200) self.assertTemplateUsed(response, 'products/home.html') self.assertContains(response, 'test') I get AssertionError: False is not true : Couldn't find 'test' in response.

Why are the selected values removed from the multi select in the admin page?
I wrote a multi-select form for the admin page. The selected data is saved in the database, but for some reason it is not displayed as selected (no selected property).

How to Prefill Form with URL Parameters (Django)
I would like to prefill a form with URL parameters, but I am unsure as to how I should configure my URLs. I need to fill multiple fields, so is using URL parameters still the best method? In the tutorials I have been reviewing, most cases only use 1 or 2 parameters from the GET request. In my view, I am only handling one field currently as I am having trouble with just one parameter. You can see in the form model the other fields I would like to fill. Any help is greatly appreciated! views.py def new_opportunity_confirm(request): form_class = OpportunityForm account_manager = request.GET.get('account_manager') form = form_class(initial={'account_manager': account_manager}) return render(request, 'website/new_opportunity_confirm.html', {'form': form}) urls.py re_path(r'new_opportunity/new_opportunity_confirm/(?P<account_manager>\w+)/$', view=views.new_opportunity_confirm, name='new_opportunity_confirm'), new_opportunity_confirm.html <form action="" method="post" name="newOpportunityForm" id="newOpportunityForm"> {% csrf_token %} <div class="field"> <label class="label">Account Manager:</label> <div class="select"> <select name="account_manager" id="account_manager" required> <option value="{{ form }}">{{ form }}</option> </select> </div> </div> -

Django and OAuth2 - 403 Unauthorized: Authentication credentials were not provided & 401 Forbidden

`manage.py inspectdb` tells me that I don't have an ENGINE specified in my default database, but the docs say that default can be blank
I'm creating a django web app that is going to be a database management portal for multiple databases. Because the web app will touch multiple databases, it doesn't make sense to have a default. However, when I run manage.py inspectdb I get an error saying that the ENGINE value isn't set on my database. It most definitely is. Here's my DATABASES setting in settings.py DATABASES = { 'default': { }, 'my_db': { 'NAME': 'my_db', 'USER': 'user', 'PASSWORD': 'pass', 'HOST': '192.168.0.255', 'PORT': '', 'ENGINE': 'sql_server.pyodbc', 'OPTIONS': { 'driver': 'ODBC Driver 13 for SQL Server', }, }, } If I run manage.py inspectdb using this setup I get this error: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details. This doesn't make sense to me, since it says in the documentation that 'default' can be a blank {}. However, if I supply a dummy NAME and ENGINE variable to the default db, it seems to work fine for the default DB, but it ignores my_db. If I set default to look at my_db's information I get a login error (so I know at least something is working right there, even if my creds are bad). So, … -

Django: send message to all users (sessions)
I have a python+django project and want to implement following functionality: by certain trigger (at certain time or by manual admin action) show message to all active users (i.e. to all sessions). Webpush seems unnecessary here as far as django has nice built-in messages subframework. I guess I may develop such functionality manually: make sql table session_messages, each time take snapshot of all sessions and show message, perform some checks to assure that message is shown only once and only to active users, etc. etc. Question: maybe there is some nice little library that already does it? Or even maybe django messages are able to do it "from the box"? I've googled a bit but found only packages for webpush integrations. Thanks :) -

How to interact with a REST api made with DRF
I am trying to use a REST api made with django REST framework to send data to my react native app. For authentification, I am using allauth which creates an authtoken when a user is created. My problem is: I don't know what to do next (once I have the token). I want to be able to retrieve my user's data with the API, but I don't know how to handle the authentification with DRF. Do I have to send the token every time I make a request? If yes, what would the json would like? (frontend with react native) How do I send the data back? Would it look like this: def sendUsername(request): return request.user.get_username() if not how? and if yes, it doesn't look very safe so is there a way to make it at least a little bit more secure? I am really new to this so sorry if it looks dumb. Thank you for your time. -

Manager still not available event with the get_user_model method
I'm trying to give the user the possibility to update his profile. The situation is the following : I have a custom User Model (Member) with a Babysitter Profile available under the unique condition to precise that you are a Babysitter. I almost found a way to get the complete form (Member + Babysitter - two forms in one). But there are two issues, the main issue is when i'm trying to save the entire profile after the update, i still get the following message : "Manager isn't available; 'auth.User' has been swapped for 'accounts.Member'", event with the get_user_model method. And the second issue, less important for now, is that i don't find a way to get the actual data displayed in form so the user can update it.
