Login page isn't redirecting - Django
I'm trying to create a basic authentication page with user and password, and it is almost working, almost. I found that the authentication process is working but the app is failing at redirecting to the home page. Here's the code From Views def home(request): print(request.user) if request.user.is_authenticated: return render(request, "home/home.html") else: return redirect("login/") def login(request): error = '' if request.method == "POST": username = request.POST['username'] password = request.POST['password'] try: user = AppUser.objects.get(email=username) except AppUser.DoesNotExist: error = 'Usuario no encontrado' return render(request, 'login.html', {'error': error, 'form': Login()}) if hasattr(user, 'appuserauth'): if user.appuserauth.check_password(password): uauth = authenticate(request, username=user.email, password=password) if uauth is not None: login(request, uauth) return redirect("home") else: error = 'Contraseña incorrecta' return render(request, 'login.html', {'error': error, 'form': Login()}) else: error = 'El usuario no tiene una contraseña' return render(request, 'login.html', {'error': error, 'form': Login()}) else: return render(request, "login.html", { "form": Login(), "error": error }) From urls from django.urls import path from . import views urlpatterns = [ path('home/', views.home, name='home'), path('inventario/', views.inventario, name='inventario'), path('compras/', views.compras, name='compras'), path('ventas/', views.ventas, name='ventas'), path('login/', views.login, name='login'), ] Does someone know what I'm doing wrong? enter image description here Thanks I've tried changing from redirect to render, and I also tried to track the redirection.

Django form validation errors not displaying with Bootstrap alert alert-danger styling
I'm working on a Django project where I'm using Bootstrap to style my form validation error messages. However, while the form validation works (I can see the errors in plain text), the errors are not being styled with the alert alert-danger classes from Bootstrap. I've confirmed that Bootstrap is properly included, but the error messages still appear unstyled. Here’s the relevant code from my form template: <section class="gallery" style="margin-left: 5em"> <form action="{% url 'register' %}" method="POST"> {% csrf_token %} <div class="row"> {% for field in form.visible_fields %} <div class="col-12 col-lg-12" style="margin-bottom: 10px;"> <label for="{{ field.id_for_label }}" style="color:#D9D9D9; margin-bottom: 5px;">{{ field.label }}</label> {{ field }} {% for error in field.errors %} <div class="alert alert-danger" style="margin-top: 5px;"> {{ error }} </div> {% endfor %} </div> {% endfor %} </div> <div> <button type="submit" class="btn btn-success col-12" style="padding-top: 5px;">Register</button> </div> </form> </section> Here’s what I’ve tried so far: Bootstrap inclusion: I've included the following link in my HTML file to ensure Bootstrap is loaded: <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.2.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-Zenh87qX5JnK2Jl0vWa8Ck2rdkQ2Bzep5IDxbcnCeuOxjzrPF/et3URy9Bv1WTRi" crossorigin="anonymous"> I confirmed that Bootstrap is loading by inspecting the network tab and seeing that the file is fetched without errors.

queryset objects in which user has an object
App has Game model and Player model. I want to get a list of the Game objects in which the logged in user has a Player. This is to show that user's Game history in a dashboard so they can see past games. This code gets all the Game objects. So it shows the history of every user. class DashboardListView(generic.ListView): model = Game template_name = 'dashboard.html' context_object_name = 'tournament_list' def get_queryset(self): return Game.objects.filter() I can narrow down to completed games for every player like this: class DashboardListView(generic.ListView): model = Game template_name = 'dashboard.html' context_object_name = 'tournament_list' def get_queryset(self): return Game.objects.filter(completed=True) I tried this to get to narrow down to only games of the specific user: def get_queryset(self): if Player.objects.filter(owner=self.request.user).exists(): mine = Player.objects.filter(owner=self.request.user).get() return Game.objects.filter( Q(player1=mine) | Q(player2=mine) | Q(player3=mine) & Q(completed=True)) But because there are multiple Player objects it throws this error: get() returned more than one Player -- it returned 12! What I want are the 12 Games in which the user has those 12 Player objects. How can I get those Game objects in which the user has a Player object? -
Why is my Avatar component not appearing on navbar?
I have been trying to get the avatar icon of user profile image to appear on the navbar but the word 'avatar' just appears instead next to 'Profile'. The Avatar icon appears perfectly fine with for my post.js I checked my API's serializer and settings, all this seems correct especially since the avatar is appearing correctly on Post.js. The API is using dj-rest-auth==6.0.0 and Django==4.2 serializers.py from dj_rest_auth.serializers import UserDetailsSerializer from rest_framework import serializers class CurrentUserSerializer(UserDetailsSerializer): profile_id = serializers.ReadOnlyField(source='profile.id') profile_image = serializers.ReadOnlyField(source='profile.image.url') class Meta(UserDetailsSerializer.Meta): fields = UserDetailsSerializer.Meta.fields + ( 'profile_id', 'profile_image' ) settings.py REST_AUTH_SERIALIZERS = { 'USER_DETAILS_SERIALIZER': 'pinch_api.serializers.CurrentUserSerializer' } Front end NavBar.js; import Avatar from './Avatar'; <NavLink className={styles.NavLink} to={`/profiles/${currentUser?.profile_id}`} > <Avatar src={currentUser?.profile_image} text="Profile" height={40} /> </NavLink> I have checked my API and searched for other solutions but I am not understanding why the avatar would appear for posts but not for navbar. Does anybody have suggestions what the problem would be? -
Django ModelDiffMixin: Maximum recursion depth exceeded
I am getting a weird error after upgrading the Django version from 4.0 to 4.2.15. The error being encountered is: RecursionError: maximum recursion depth exceeded while calling a Python object. The ModelDiffMixin looks something like below: from django.forms.models import model_to_dict class ModelDiffMixin(object): def __init__(self, *args, **kwargs): super(ModelDiffMixin, self).__init__(*args, **kwargs) self.__initial = self._dict @property def diff(self): d1 = self.__initial d2 = self._dict diffs = [(k, (v, d2[k])) for k, v in d1.items() if v != d2[k]] return dict(diffs) @property def has_changed(self): return bool(self.diff) @property def changed_fields(self): return self.diff.keys() def get_field_diff(self, field_name): """ Returns a diff for field if it's changed and None otherwise.

Solr Search Not Returning Expected Results in Django with Haystack
I'm working on a Django project using Haystack for search functionality with Solr as the backend. I've set up everything, but when I perform a search, the results are not returned as expected. Problem Description I have a search view that queries Solr for products based on a search term. While the search query executes without errors, the returned results do not contain any products, even though I have verified that products exist in the database. views.py: from haystack import indexes from haystack.query import SearchQuerySet from django.shortcuts import render def search_view(request): query = request.GET.get('q') results = SearchQuerySet().filter(content=query) if query else [] print(f"Search Query: {query}, Results: {results}") context = { 'results':results, 'query':query, } return render(request, 'core/search.html', context) Search_indexes.py: from haystack import indexes from core.models import * class Solr_Model_Index (indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) def get_model(self): return Product def index_queryset(self, using=None): """Used when the entire index for model is updated.""" return self.get_model().objects.all() Steps Taken: Rebuilt the Index: I ran python manage.py rebuild_index to ensure all products are indexed.

Django Channels websocket connection failed
I am working on a demo chat application as part of my learning process with Django Channels and WebSockets. My goal is to establish real-time communication using WebSockets, but I'm facing an issue where the connection to the WebSocket fails.

Is it possible to have a child model with multiple parents in a Django App?
I am creating a quiz back-end. I would like to add a feature where a user can report a question for being irrelevant or not fair. I have 3 relevant models for this in my Django app: User Model Question Model Report Model I would like to record what user created the report and also what question was reported. Is it possible to have a Many to 1 relationship between Report:User and also a Many to 1 relationship between Report:Question too? The report model would have two parents - User and Question. Is there a better way of doing this? -

Django not connecting to proper DB [closed]
I'm building a rather small backend component with Django and I got it connected to an external Postgre DB. The issue is, when I started the Django app and tried to fetch some data all I got is a 204 No content response (which is what I'd expect if there is no data in DB) but the DB has data, which make me think my app is not connecting to the proper DB. This is my DB config which was working before and is working in my deployed component: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': os.environ.get('DATABASE_NAME'), 'USER': os.environ.get('DATABASE_USERNAME'), 'PASSWORD': os.environ.get('DATABASE_PASSWORD'), 'HOST': os.environ.get('DATABASE_HOST'), 'PORT': os.environ.get('DATABASE_PORT'), } } There is no error showing up at all, just my DB has some test data which I can access through pgAdmin (pgAdmin result) and I also can get the data through postman calling the current deployed component (GET /api/products/ HTTP/1.1" 200 899 "-" "PostmanRuntime/7.41.0"/) -
Django as_field_group?
How can I modify the as_field_group method to change the order of its returned values? Currently, the method returns the label, error message, and then the input field.

How can I either override or customize the as_field_group method to achieve this? -
How to retrieve filtered queryset used to render form fields in Django?
I have a Django form that contains a table with rows that reflect course objects from a database . Each row contains a checkbox input. This form also has some submit buttons that allow the user to filter the course objects shown in the table (besides a generic submit button). This form is used to update the users profile with courses they are interested in. When the form is submitted, courses in the filter that are unchecked should be removed from the interested M2M relation and checked ones should be added to it. To do that I need to know which inputs are checked , which I know how to retrieve, but I also need to know which courses are in the table that have unchecked inputs. Retreiving this is not as easy as ‘all the other courses in the database’ because my table does not always contain all course objects. If a user previously clicked one of the filter buttons, then the table contains only a filtered set of courses. So I need to know which courses were used to create the table at rendertime, i.e. the ones that were injected as HTML context variable. Of course I know … -

How to customize Django Oscar category_tree template tag and remove pk from category URLs?
I'm working on an eCommerce project using Django Oscar, and I've run into an issue that I can't seem to solve. My goal is to customize the category URLs to only use slugs instead of both slug and pk, but I'm having trouble implementing this. Here's what I've done so far: What I Want to Achieve: I want to remove the pk from the category URLs in Django Oscar. Right now, my URLs look like this: http://127.0.0.1:8000/category/metal-detectors_2/ I would like them to look like this: http://127.0.0.1:8000/metal-detectors/ My Setup: I'm using a forked catalogue app from Django Oscar, where I'm making my customizations. I have a custom template categories.html in which I am trying to loop through categories and their child categories. I have created a custom template tag category_tree in a templatetags folder under the catalogue app to handle category rendering. Problem: I am using the {% category_tree as tree_categories %} template tag to render categories, but it seems to be failing due to the use of pk in the URL construction. I want to modify it to only rely on the category_slug. However, I keep getting the following error: NoReverseMatch: Reverse for 'category' with keyword arguments '{'category_slug': 'metal-detectors', 'pk': … -

How to configure two server domains in django-anymail
I'm working on a Django project and using Anymail with Mailgun to send emails. I have two domains pointing to same site domain1.com and domain2.com I set up mailgun both senver domains as mg.domain1.com and mg.domain2.com both with their api key. Both domains worked fine when set as default domain senders. I need to send client email and switch them depending if they are users of domain1 or domain2. Because I want the serder email will be noreply@domain1.com and noreply@domain2.com depending on the user. In my settings.py, I have the following configuration: ANYMAIL = { 'MAILGUN_API_KEY': API_KEY_DOMAIN1, 'MAILGUN_SENDER_DOMAIN': SENDER_DOMAIN_1'], } EMAIL_BACKEND = 'anymail.backends.mailgun.EmailBackend' SERVER_EMAIL = noreply@domain1.com DEFAULT_FROM_EMAIL = Domain 1 <noreply@domain1.com> Here is send email code: email = AnymailMessage( to=message.to.split(','), cc=message.cc.split(',') if message.cc else None, bcc=message.bcc.split(',') if message.bcc else None, reply_to=None, subject=message.notification.subject, body=message.notification.body_text, from_email=message.from_email, ) email.attach_alternative(message.notification.body_html, 'text/html') if user.brand['name'] == 'domain2': email.esp_extra = { 'sender_domain': SENDER_DOMAIN_2, 'api_key': API_KEY_DOMAIN2, } try: email.send() except Exception as e: print('Error sending email:', e) As you can see. I try to use esp_extra to switch between sender domain, but I get: anymail.exceptions.AnymailRequestsAPIError: Mailgun API response 401 (Unauthorized): 'Forbidden' What could be causing this issue, and how can I resolve it? -
Video Not Displaying on Vercel Deployment in Django Project (Works Locally)
I'm working on a Django project where I'm displaying a video using the tag. The video works perfectly on my local development server, but once I deploy the project to Vercel, the video does not load. Here’s the HTML code I’m using to display the video: I tried using both {{ video_url }} and the {% static %} tag to load the video file from the static/videos directory. I also ensured the video file was collected using collectstatic and updated the vercel.json file to serve static files correctly. I expected the video to load and play as it does on the local development server. However, after deploying to Vercel, the video doesn’t show up at all. No error messages are shown in the browser console.
