Why am I getting a 404 error with /None appended to the URL in my Django application? [closed]
it appears that after every successful request to a valid URL (e.g., /tasks/manager-dashboard/, /users/admin/dashboard/, etc.), an additional request is made to the same URL but with None appended to the end (e.g., /tasks/manager-dashboard/None). This results in a 404 Not Found error. Why are all my routes being redirected to /None? What could be causing this issue, and how can I fix it? Here’s the relevant log from my terminal: [03/Feb/2025 06:13:55] "GET / HTTP/1.1" 200 22745 Not Found: /None [03/Feb/2025 06:13:55] "GET /None HTTP/1.1" 404 16655 [03/Feb/2025 06:13:59] "GET /tasks/dashboard/ HTTP/1.1" 302 0 [03/Feb/2025 06:14:01] "GET /tasks/manager-dashboard/ HTTP/1.1" 200 30428 Not Found: /tasks/manager-dashboard/None [03/Feb/2025 06:14:01] "GET /tasks/manager-dashboard/None HTTP/1.1" 404 18835 [03/Feb/2025 06:14:07] "POST /users/logout/ HTTP/1.1" 302 0 [03/Feb/2025 06:14:07] "GET / HTTP/1.1" 200 22083 login form initialized [03/Feb/2025 06:14:08] "GET /users/login/ HTTP/1.1" 200 21320 login form initialized [03/Feb/2025 06:14:19] "POST /users/login/ HTTP/1.1" 302 0 [03/Feb/2025 06:14:20] "GET /tasks/dashboard/ HTTP/1.1" 302 0 [03/Feb/2025 06:14:22] "GET /users/admin/dashboard/ HTTP/1.1" 200 34903 Not Found: /users/admin/dashboard/None [03/Feb/2025 06:14:22] "GET /users/admin/dashboard/None HTTP/1.1" 404 19097 [03/Feb/2025 06:14:31] "GET /users/admin/user-list/ HTTP/1.1" 200 26112 Not Found: /users/admin/user-list/None [03/Feb/2025 06:14:31] "GET /users/admin/user-list/None HTTP/1.1" 404 19097 [03/Feb/2025 06:14:58] "GET /users/admin/user-list/ HTTP/1.1" 200 26111 Not Found: /users/admin/user-list/None [03/Feb/2025 06:14:58] "GET /users/admin/user-list/None HTTP/1.1" … -

Save all objects in QuerySet and related objects to a fixture
I've written a function to save a QuerySet to a fixture JSON file: def save_as_fixture(query_set: QuerySet, fixture_name: str, app_label: str='mainapp'): app_config = apps.get_app_config(app_label) fixture_dir = os.path.join(app_config.path, "fixtures") os.makedirs(fixture_dir, exist_ok=True) fixture_path = os.path.join(fixture_dir, fixture_name) data = serializers.serialize("json", query_set, indent=2, use_natural_foreign_keys=True, use_natural_primary_keys=True) with open(fixture_path, 'w') as file: file.write(data) But it doesn't save related objects. I would like it to also save the objects that reference one of the objects of the QuerySet via a ForeignKey, OneToOneField, etc. How can I do that? -
Does `.all()` in Django re-query the Database or use the cache?
I am getting very conflicting messages. From Django Queryset docs, I am reading (https://docs.djangoproject.com/en/5.1/ref/models/querysets/#django.db.models.query.QuerySet.all): When a QuerySet is evaluated, it typically caches its results. If the data in the database might have changed since a QuerySet was evaluated, you can get updated results for the same query by calling all() on a previously evaluated QuerySet. But then under the prefetch_related section, it shows that using .all() on the sub-objects uses results from the cache: >>> restaurants = Restaurant.objects.prefetch_related( ... Prefetch("pizzas", queryset=queryset), ... ) >>> vegetarian_pizzas = restaurants[0].pizzas.all() Here, apparently vegetarian_pizzas doesn't trigger a database query. So...which is it - what does all() actually do? Why does it trigger a database query on the outer but then not for sub-objects? I'm confused. -
Filter by ManyToManyField, one way
I have a model with a ManyToManyField: class Release(models.Model): #... bundled_releases = models.ManyToManyField("self", blank=True) def get_bundles(self): return Release.objects.filter(bundled_releases__in=[self.id]) I want get_bundles to only return releases that have self in their bundled_releases fields, but this way it also returns releases in self's bundled_releases field. How do I do this? -
Django: setting up project/app to use Jinja syntax in Markdown posts
I'm migrating my website from Eleventy to Django. I had Eleventy set up with some custom Nunjucks filters/shortcodes or whatever they're called so I could use Nunjucks for including responsive web images as well as custom HTML media player code for video files, instead of having to write out HTML in the Markdown file every time. I'm trying to replicate that simplification in Django via Jinja (as it's basically the same thing, by Nunjucks' own admission), but I'm having a time wrapping my head around the learning curve for the different things I need to tackle in order to do this. From what I think I understand so far, I have a few obstacles: Figuring out how to get my Django project/app to process Jinja syntax in Markdown files and convert it to HTML. I found what looks like a good context explainer here (https://stackoverflow.com/a/32254521/21423257), but it's more of a general heads-up and doesn't explain what you need to actually do to your project/app to make this work. I'm using the Markdown plugin, I assume that will be adequate but if not, I'm open to using one of the other Markdown plugins if they're better suited for this task. Posting … -
Use Oauth2+Django to get authorization toaccess user's Gmail
I was using this tutorial: https://www.geeksforgeeks.org/python-django-google-authentication-and-fetching-mails-from-scratch/. However, the oauth2client library is deprecated and hasn't been touched in almost 9 years. I have looked for various tutorials, but they seem to be written by AI; they make no sense, and do things like tell you to include credentials in a piece of code that does not use credentials. So my question is, how can I implement oauth2 into my Django application so that user's can go to the Django website and give permission to read their emails? -
Gmail Oauth2 - restrict scope to only apply to emails from a certain domain [closed]
I have a Django site that uses Google Oauth2 to allow users to grant access to read and reply to their emails. GOOGLE_OAUTH2_CREDENTIALS = { 'client_id': '********************', 'client_secret': '*******', 'scope': [ 'https://www.googleapis.com/auth/gmail.readonly', 'https://www.googleapis.com/auth/gmail.send' ], 'redirect_uri': 'https://www.********.com/*****/', } However, for privacy and security purposes I want to set restrict the scope to only being able to read and reply to emails from a specific domain. Is it possible to modify the scope to only allow the permissions within for emails to/from a certain domain? -
Docker port forwarding not working Django app
I have a Django app that works fine locally when I run it without a container. However, when I containerize the app, create an image, and run the container, the app is not accessible at the forwarded port: http://localhost:8081 When I exec into the container and run the curl command: curl localhost:8005 I am able to see the response inside the container. Here is my Dockerfile, which I am using to build the image and run the container with some environment variables, which are present when I exec into the container: FROM python:3.11 ENV PYTHONUNBUFFERED 1 RUN mkdir /app WORKDIR /app COPY requirements.txt /app RUN pip install --upgrade pip RUN pip install -r requirements.txt COPY . /app EXPOSE 8005 #ENTRYPOINT ["bash", "entrypoint.bash"] CMD ["python", "manage.py", "runserver", "0.0.0.0:8005"] To build the image and run the container, I use the following commands: docker build -t app_backend:v1 . docker run -dit --rm -p 8081:8005 --name app_backend app_backend:v1 For testing, I tried running a sample command and was able to access Nginx on port 8009, but I cannot access the Django app at the specified port: docker run -d -p 8009:80 nginx:alpine -
How can I reduce the number of queries in a queryset?

Does calling a method from template query the database each time?
Say you have the following method in a model: def get_images(self): return ReleaseImage.objects.filter(release=self.id) And you call it from a template like so: {% if release.get_images %}{{ MEDIA_URL }}{{ release.get_images.first }}{% endif %} Does the database get queried twice, or is there some behind-the-scenes optimization that prevents this? It might be highly inefficient if not. -
Issue with Django Login Form: Form is Invalid Despite Correct Credentials
I've been facing an issue with my Django login form. Despite providing the correct credentials, the form consistently returns as invalid. Here’s a detailed description of my setup and the problem I’m encountering. Description I'm using Django's AuthenticationForm to handle user login. My goal is to authenticate users and redirect them to a specific page upon successful login.

How to make Pre-commit ignore when an element is not accessible?
I have this config in my app.rb : from django.apps import AppConfig class WebsiteConfig(AppConfig): default_auto_field = "django.db.models.BigAutoField" name = "website" def ready(self): import website.signals The "website.signals" is not accessible (Pylance) because I am using docker. When the pre-commit is running, it will change my code to: from django.apps import AppConfig class WebsiteConfig(AppConfig): default_auto_field = "django.db.models.BigAutoField" name = "website" def ready(self): pass How do I bypass this in general in my pyproject.toml?

with regard to form.save(commit=False), what am I missing?
As explained in many posts like the following: Why do we use "form.save(commit=False)" in Django-views? "The main use case is if you have a ModelForm that doesn't contain all the required fields of a model. You need to save this form in the database, but because you didn't give it all the required fields, you will get an error.." which is all good and dandy but why not just complete all the instance fields and then call the regular save? In the bellow example: # Creates a Dog class with all fields as mandatory: class Dog(models.Model): name = models.CharField(max_length=50) race = models.CharField(max_length=50) age = models.PositiveIntegerField() # Creates a ModelForm with only name and age: class DogForm(forms.ModelForm): class Meta: model = Dog fields = ['name', 'age'] # In your view use this form: def dog_view(request): ... form = DogForm(request.POST or None) # If the form is valid we need to add a race, otherwise we will get an error: if form.is_valid(): dog = form.save(commit=False) # Define the race here: dog.race = 'Labrador retriever' # And then do the regular save to push the change in the database: dog.save() ... why not just say: form = DogForm(request.POST or None) # Define the … -

I have a following serializer definitions that validate request payload: # diagnosis serializer class ICD10Serializer(serializers.Serializer): icd_10 = serializers.IntegerField(required=True, allow_null=False) class DetailsSerializer(serializers.Serializer): diagnosis_details = ICD10Serializer(many=True) class ChartUpdateSerializer(serializers.Serializer): diagnosis = DetailsSerializer(many=True) Its usage: payload = ChartUpdateSerializer(data=request.data) if not payload.is_valid(): raise serializers.ValidationError(payload.errors) This throws validation error message in the following format: { "diagnosis": [ { "diagnosisDetails": [ {}, <- valid {}, <- valid {}, <- valid {}, <- valid { "icd10": [ "This field may not be null." ] } ] } ] } Here {} is also shown for valid ones. Can we simply raise validation error for invalid ones? Or better even if we can know which field and the message so custom message can be generated. -
Information on using Twilio with Whatsapp
I am making an app with Django and react about a clinic. My clients want to send automatically the appointment through WhatsApp to their patients. I have been reviewing the Twilio documentation, as I understand, I need that the phone number I use to send the WhatsApp must be WhatsApp Business. Can anyone help me on how to perform this function? I have never used Twilio, and I am very lost, I also don't understand how I am going to be able to test that it works correctly before launching it. Thanks in advance for the help. -
