django-mathfilters: How to calculate totals with mathfilters
I need to calculate and display a sum total of maintenance and sinking funds listed on a page. My template is as follows: {% extends "base.html" %} {% load mathfilters %} <div class="container"> <div class="col-md-10 offset-md-1 mt-5"> <div class="jumbotron"> <h1 class="display-4">Unit List</h1> <hr class="my-4"> {% block content %} <form class="d-flex" role="search" action="{% url 'billing-list' %}"> <input class="form-control me-2" type="search" placeholder="Search for OWNER, PROPERTY, BLK or UNIT NUMBER" aria-label="Search" name="search"> <button class="btn btn-outline-success" type="submit">Search</button> </form> <table class="table table-borderless"> <thead class="border-bottom font-weight-bold"> <tr> <td>Property Name</td> <td>Block</td> <td>Floor Number</td> <td>Unit Number</td> <td>Owner</td> <td>Share Value</td> <td>Ownership Start Date</td> <td>Monthly Maintenance Fee Payable</td> <td>Monthly Sinking Fund Payable</td> <td> <a href="{% url 'pdf-list' %}" class="btn btn-outline-success"> <i class="fa-thin fa-file-pdf"></i> PDF </a> <a href="{% url 'email' %}" class="btn text-secondary px-0"> <i class="fa-solid fa-envelope"></i> Email </a> </td> </tr> </thead> <tbody> {% for unit in unit_list %} <tr> <td>{{unit.property}}</td> <td>{{unit.block}}</td> <td>{{unit.floor}}</td> <td>{{unit.unit_number}}</td> <td>{{unit.owner}}</td> <td>{{unit.share_value}}</td> <td>{{unit.ownership_start_date}}</td> {% with unit.maintenance_fee_monthly as maint %} {% with unit.share_value as share %} <td>{{maint|mul:share|div:100}}</td> {% endwith %} {% endwith %} {% with unit.sinking_fund_monthly as sink %} {% with unit.share_value as share %} <td>{{sink|mul:share|div:100}}</td> {% endwith %} {% endwith %} </tr> {% endfor %} </tbody> </table> {% endblock content %} </div> </div> </div> Line items were … -
Use Django ORM in locust
I'm using locust to load test my Django application. I'm currently hardcoding certain values in my locustfile.py: GROUP_UUID = "6790f1e6-64f9-4707-aa82-d4edd64c9cc7" @task def get_single_group(self): self.client.get(f"/api/groups/{GROUP_UUID}/") This obviously fails if GROUP_UUID is not in the database, which occurs whenever I reseed my database so I'm constantly having to change these hardcoded values. It would be much better if I could dynamically fetch a group at runtime: from myapp.models import Group @task def get_single_group(self): group = Group.objects.first() self.client.get(f"/api/groups/{group.id}/") However, I'm getting the following error, which makes sense because locust doesn't know anything about Django: ModuleNotFoundError: No module named 'myapp' Is there anyway to use the Django ORM in locustfile.py or do I need to continue hardcoding data all over the place? -
Apache error "Truncated or oversized response headers received from daemon process" when using Django
We have a Django application using mod_wsgi working fine on our Ubuntu 16 instance. When we spun up a new Ubuntu 18 instance, and attempt to log into our application, we get: [Tue Jan 10 22:12:00.930300 2023] [wsgi:error] [pid 11481:tid 140103479047936] [client 10.61.23.144:61958] Truncated or oversized response headers received from daemon process 'server': /home/.../wsgi.py, referer: https://application/login/?next=/application/ [Tue Jan 10 22:12:00.931998 2023] [core:notice] [pid 6523:tid 140103626501056] AH00052: child pid 11479 exit signal Segmentation fault (11) In searching for answers, we've seen several posts suggesting that we add this line to our apache2.conf file, which we did: WSGIApplicationGroup %{GLOBAL} However, this did not address the problem. Also tried the suggestions noted on https://serverfault.com/questions/844761/wsgi-truncated-or-oversized-response-headers-received-from-daemon-process, but this also did not solve the problem. We increased Apache logging to info but aside from the "Truncated or oversized response headers" and "Segmentation fault" no other information was logged. Hoping we may have missed a trick or two. -
Django: ProfileSerializer() takes no arguments
I am trying to get the logged in user profile using django restframework api_view, i have written a simple logic to do that but it keeps showing this error that says TypeError at /api/my-profile/2/ ProfileSerializer() takes no arguments, i cannot really tell what is wrong with the code that i have written. This is the code here class MyProfileView(APIView): # queryset = Profile.objects.all() serializer_class = ProfileSerializer permission_classes = [permissions.IsAuthenticated] def get_object(self, pk): try: return Profile.objects.get(pk=pk) except Profile.DoesNotExist: raise Http404 def get(self, request, pk ,format=None): profile = self.get_object(pk) serializer = ProfileSerializer(profile) return Response(serializer.data) urls.py path("my-profile/<int:pk>/", MyProfileView.as_view(), name="my-profile"), -
Can't import value from .env file / Django
I got a file .env with 4 values to hide sensitive data: DATABASE_PASSWD=Password1 SECRET_KEY=Password2 VAR3=Password3 VAR4=Password4 All of above values are properly imported in Django code except the DATABASE_PASSWORD. When the DATABASES configuration is as follows: # settings.py from decouple import config # ... DB_PASSWORD=config('DATABASE_PASSWD') SECRET_KEY=config('SECRET_KEY') VAR3=config('VAR3') VAR4=config('VAR4') DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': "database_name", 'USER': "database_test_admin", 'PASSWORD': DB_PASSWORD, 'HOST': "localhost", 'PORT': "5432", } } The django outputs: raise UndefinedValueError('{} not found. Declare it as envvar or define a default value.'.format(option)) decouple.UndefinedValueError: DATABASE_PASSWD not found. Declare it as envvar or define a default value. If I hardcode password that is just the same in .env the problem is gone - the password is correct since it's my private project. Other variables works well with the same config('VAR#') function in views for example. I have no clue what could be wrong here. -

Do I need to clear the prefetch cache after each Django prefetch_related?
Django mentions that this is the way to clear the prefetch cache: non_prefetched = qs.prefetch_related(None) Which you should do since now the values are loaded into memory. One problem I'm finding is that this is even persisting across requests, meaning that the data is still cached even after returning in a separate session. Is this expected behavior, or am I misunderstanding? If this is the expected behavior, does this also mean I have to clear the cache at the end of every view with the call above? -

How to color value in list with django?
I am using the django framework. And I have a list with values. And the values from that list are displayed on a template. So this is the list: self.list_school_values = [ "12bg00", "Basisschool Vroonestein", "Lohengrinhof 1517, 3438RA NIEUWEGEIN Utrecht", "Lohengrinhof 1517, 3438RA NIEUWEGEIN Utrecht", "mevr.

Kees Kooijman", "Koopliedenweg 38 , 2991 LN BARENDRECHT", "verdi@qualitycontrolsystems.nl", ] and the template looks: <div class="form-outline"> <div class="form-group"> <div class="wishlist"> <table> <tr> <th>Gegevens school </th> <th>waardes school contract</th> </tr> {% for value0, value1 in content %} <tr> <td> {{value0}} </td> <td class="{% if value1 == '12bg00' %}red {% endif %}"> {{value1}} </td> </tr> {% endfor %} </table> </div> </div> </div> and css: .red { color: red; } But the value is not colored red. Question: how to color the value from the list red? -
Why is django not showing multiple error messages?
When my form has multiple error messages it only show the first one. Forms.py code: class LoginForm(AuthenticationForm): error_messages = { "invalid_login": _("Incorrect login details. Try again"), "inactive": _("This account is inactive."), } I'm just using the normal Auth form but overwriting the already existing error messages so the message says something different. Template code: <form method="POST"> {% csrf_token %} {{ form }} <button type="submit">Log in</button> </form> When a inactive user tries to login the form returns this: {'invalid_login': 'Incorrect login details. Try again', 'inactive': 'This account is inactive.'} While the user did fill in the right details. And this is the only error that gets shown: <ul class="errorlist nonfield"><li>Incorrect login details. Try again</li></ul> I want it to show either both or the inactive error message since I find that more important to know. -

There seems to be a problem with Django Urls?
When ever I run python manage.py runserver, I get a message in the terminal "Not Found: /base/". I do not have this in my urls to start off with anyways so why am I seeing this?

Using the URLconf defined in cric_manager.urls, Django tried these URL patterns, in this order: admin/ manager/ The current path, base/, didn’t match any of these. I tried to restart the termnial, VSCODE, and the webpage, but nothing seems to be working. Its getting a little bit annoying. -
How to display name of table from queryset in django

I have such a view to display class Home(ListView): template_name = 'home.html' def get_queryset(self): qs1 = Book.objects.all() qs2 = CD.objects.all() qs3 = Film.objects.all() queryset = sorted(list(chain(qs1, qs2, qs3)), key=operator.attrgetter('title')) return queryset and it returns to me this [<CD: Music1>, <CD: Music2>, <Book: Some books>] How can I get "CD" or "Book" in this template {% block content %} <div class="row"> {% for object in object_list %} <div class="col-md-3"> <div class="card card-product-grid"> <img src="{{ object.image.url }}"> <a href="{% url 'DetailBook' object.pk %}" class="title">{{ object.title }}</a> </div> </div> {% endfor %} </div> {% endblock content %} At the same time, if it's a bad idea to display detailview and listview and it's done differently, I'd appreciate it if you'd let me know I tried different ways of displaying object.key in a loop but it didn't work very well.
