Why do filters affect the result of StringAgg?
I'm using StringAgg and order as follows: # Get order column & annotate with list of credits if request.POST.get('order[0][name]'): order = request.POST['order[0][name]'] if order == 'credits_primary': releases = releases.annotate(credits_primary=StringAgg( 'credits__entity__name', delimiter=', ', filter=Q(credits__type='primary'), ordering='credits__id' )) elif order == 'credits_secondary': releases = releases.annotate(credits_secondary=StringAgg( 'credits__entity__name', delimiter=', ', filter=Q(credits__type='secondary'), ordering='credits__id' )) else: order = 'title' # Order releases if request.POST.get('order[0][dir]') == 'desc': releases = releases.order_by(F(order).desc(nulls_last=True), 'title') else: releases = releases.order_by(F(order).asc(nulls_last=True), 'title') for release in releases: try: print(release.credits_primary) except: pass try: print(release.credits_secondary) except: pass This in itself works exactly as expected: the ordering is what I expect, and print returns the values I expect. However, when I apply filters before this, it starts behaving strangely. Namely, sometimes it's fine and still works as expected, sometimes each credits__entity__name is repeated a random number of times, sometimes the annotation just returns None even though there are values. I can't figure out a pattern here. Below are the filters I'm applying, note that exclude as far as I can tell does not cause this problem: if request.POST.get('entity'): releases = Release.objects.filter(credits__entity=request.POST['entity']) else: releases = Release.objects.all() records_total = releases.count() # Filter by type if request.POST.get('type'): query = Q() for type in loads(request.POST['type']): if type in Release.TYPES_P_TO_S: query.add(Q(type=Release.TYPES_P_TO_S[type]), Q.OR) releases … -
Why is the data-tags attribute not preserved in my Django form widget? autoComplete DAL Select2
I'm using a CharField with a custom widget (ListSelect2) from the django-autocomplete-light library. I have a set of data-* attributes, including data-tags, that I want to be passed to the HTML output, but it doesn't seem like the data-tags attribute is being preserved or rendered correctly in the final after form is saved. industry_type = forms.CharField( widget=autocomplete.ListSelect2( url='/career-listings/industry-autocomplete/', attrs={ 'class': 'w-full px-4 py-2 border border-gray-300 rounded-lg shadow-sm focus:outline-none focus:ring-2 focus:ring-blue-500 focus:border-blue-500 transition duration-200', 'data-placeholder': 'Industry', 'data-minimum-input-length': 1, 'data-theme': 'tailwindcss-3', 'data-tags': 'true', # The attribute I'm trying to preserve 'id': 'id_industry_type', }, forward=['name'], ), required=True, ) What happens instead: The data-tags attribute does not appear in the HTML after form is saved. The field Things I've tried: I added data-tags to the attrs dictionary of the widget. I ensured that the widget is being properly rendered in the template. The data only data-tags is not preserved on form is submitted. -
Getting list of distinct ManyToManyField objects
Given these models: class Format(models.Model): name = models.CharField(unique=True) # More fields... class Release(models.Model): formats = models.ManyToManyField(Format, blank=True) # More fields... When I have a queryset of Releases (e.g. through releases = Release.objects.filter(foo='bar')), how do I get a list of the formats in that queryset, as objects and distinct? Neither of the following achieve this: # produces a list of dicts with IDs, not distinct e.g. [ { 'formats': 1 }, { 'formats': 2 }, { 'formats': 1 } ]: formats = releases.values('formats') # produces a list of IDs, not distinct, e.g. [ 1, 2, 1 ]: formats = releases.aggregate(arr=ArrayAgg('platforms'))['arr'] The only way I can think of is manually creating a list by looping through the IDs, checking if it already exists in the list, and if not adding it with formats.append(Format.objects.get(id=the_id)), but I would really like to avoid doing that, if possible. -
(fields.E331) Field specifies a many-to-many relation through model, which has not been installed
When I run makemigrations I get the error teams.Team.members: (fields.E331) Field specifies a many-to-many relation through model 'TeamMember', which has not been installed. from django.db import models from django.conf import settings from common import TimestampMixin from users.models import User class Team(models.Model, TimestampMixin): name = models.CharField(max_length=100) owner = models.ForeignKey( User, related_name='owned_teams', on_delete=models.CASCADE ) members = models.ManyToManyField( User, through='TeamMember', related_name='teams' ) def __str__(self): return self.name class TeamMember(models.Model, TimestampMixin): user = models.ForeignKey( User, on_delete=models.CASCADE ) team = models.ForeignKey( Team, on_delete=models.CASCADE ) def __str__(self): return f"{self.user} in {self.team}" I don't get why it's happening because the 'teams' app is installed and both Team and TeamMember is in the same file. Any ideas? -

why does the terminal say PATCH but no change in database
in my webpage, i update the request details to approve or reject. but it does not change in the status and still shows pending. the problem is, in my terminal it says PATCH so I though that means change and the database has been changed. but when I run my SQL shell, it still shows pending . what would the problem be? this is my handlestatusupdate code in the frontend: **const handleStatusUpdate = async (newStatus: 'approved' | 'rejected') => { if (!selectedRequest?.id) return; try { const response = await fetch(`${API_URL}/requests/${selectedRequest.id}/`, { method: 'PATCH', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ status: newStatus }), }); if (!response.ok) { throw new Error('Failed to update request status'); } const updatedRequest = await response.json(); setRequests(requests.map(req => req.id === selectedRequest.id ? updatedRequest : req )); setShowModal(false); } catch (err: any) { setError(err.message || 'Failed to update status'); } }; ** what other code would i need to share? the backend? -
How to create django site variables (NOT constants)?

Is it possible to use python-social-auth's EmailAuth with drf-social-oauth2 for registration
I have a facebook authentication in my project, and I've set up some pipelines. So It would be nice for non-social email registration to also utilize these pipelines. I tried adding EmailAuth to the authentication backends list, but I don't know what view to use now for registratioin. So, is it possible (or reasonable) to use EmailAuth with drf-social-oauth2 for non-social registration, and if so, how do I do it? -
Django Search Query Vulnerable to XSS - How to Prevent It?
I am working on a Django search functionality, and I noticed that when I pass JavaScript code in the URL query parameter, it executes on the page. Problem When I enter the following URL in my browser: http://127.0.0.1:8000/search/?q=%3Cscript%3Ealert(%27Hacked!%27)%3C/script%3E it shows an alert box with "Hacked!". I suspect my site is vulnerable to Reflected XSS. views.py from django.shortcuts import render def search_view(request): q = request.GET.get("q", "") # Get query parameter return render(request, "search.html", {"q": q}) search.html <h1>Search Results for: {{ q }}</h1> <!-- Displays the search query --> If I enter <script>alert('Hacked!')</script> in the search box, the JavaScript executes on the page instead of being displayed as plain text. What I Need Help With Why is this happening? What is the correct way to prevent XSS in this case? Does Django provide a built-in security mechanism for this? I appreciate any guidance on securing my search functionality. -

How can i edit external link format converter rule in wagtail cms draftail editor
When someone adds an external link in Wagtail CMS, they should have the option to choose whether to make the link 'nofollow' or 'noreferrer.' To achieve this, I have inherited the existing link form, and the code is provided here class CustomExternalLinkChooserForm(ExternalLinkChooserForm): rel = forms.ChoiceField( choices=[ ("noreferrer", "Noreferrer"), ("nofollow", "Nofollow"), ], required=False, label=_("Rel Attribute"), ) i have also inherited view class CustomExternalLinkView(ExternalLinkView): form_class = CustomExternalLinkChooserForm i registered this in wagtail hooks so admin take this override core view @hooks.register("register_admin_urls") def register_custom_external_link_view(): return [ path( "admin/choose-external-link/", CustomExternalLinkView.as_view(), name="wagtailadmin_choose_page_external_link", ) ] By using the above, it gives me an output like this, but the main issue is that when the Draftail rich text editor saves the link in the database, it does not add the rel attribute in href url. How can I solve this issue? -

Tailwind CSS does not generate CSS for all classes
I'm new to Tailwind CSS and I'm looking to include it in my Django/FastAPI project. I'm using Tailwind version 4.0.17. The problem I'm having is that Tailwind doesn't recognize the HTML tags I have in my template files... I run the following command : npx tailwindcss -i ./static/css/input.css -o ./static/css/output.css This generates a CSS file for me, but it doesn't have all the classes in it... On the other hand, when I test with this command : npx tailwindcss --content ./templates/test_endpoint.html --dry-run > output.css This time, all the CSS classes of the HTML template are present in the output file, but not the others (those of the other HTML templates). Here is the code for the tailwind.config.js file: /** @type {import('tailwindcss').Config} */ module.exports = { content: [ "./templates/**/*.html", "./templates/*.html", "templates/main/index.html", "templates/base.html", "./**/templates/**/*.html", "./static/**/*.css", "./fastapi_app/**/*.html", "./main/**/*.html" ], theme: { extend: {}, }, plugins: [], } I've tried reinstalling Tailwind several times, changing the paths, trying other commands, and the result is always the same. If you have any ideas on how to solve this problem, that would be great! Thanks -
Most efficient way to write a "Many to Occasional" field in Django
So I read that ManytoMany fields in Django were slower than ForeignKey lookups (as they make use of a helper table). I am creating an application that allows performers to catalog their acts. Each act they have in their catalog can have multiple images. However, I also want to specify one "Hero Image" of the Act which will be used for preview when they search through their catalog. each act can have many images, but only one of those could be a header image. I came up with three options but I want to hear what the hive has to think.

So I'm having trouble connecting my postgresql db server. I'm relatively new to Ubuntu, this is a brand new computer. My db name, username and password are all correct as per my Django settings. I hope I don't have to edit my pg_hba.conf file. I had similar issues regarding this with Fedora, but I didn't think I would have this problem with Ubuntu. I did in fact create a new database via the linux terminal. I'm also in my virtual environment. I even tried opening the psql shell and got more warnings. Here is the complete trackeback error after running python manage.py makemigrations and psql. FYI the name for my Ubuntu system is corey-james show_sunset_warning() /home/corey-james/Arborhub/arborhubenv/lib/python3.12/site-packages/django/core/management/commands/makemigrations.py:160: RuntimeWarning: Got an error checking a consistent migration history performed for database connection 'default': connection to server at "localhost" (127.0.0.1), port 5432 failed: FATAL: password authentication failed for user "cortec" connection to server at "localhost" (127.0.0.1), port 5432 failed: FATAL: password authentication failed for user "cortec" warnings.warn( No changes detected (arborhubenv) corey-james@corey-james-HP-Laptop-14-dq0xxx:~/Arborhub/MyProject$ psql psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL: role "corey-james" does not exist (arborhubenv) corey-james@corey-james-HP-Laptop-14-dq0xxx:~/Arborhub/MyProject$ -
Django + HTMX: how to have a CreateView that looks up information via HTMX and updates the form dynamically?
I'm a python and Django newbie. Also a newbie in StackOverflow... I'm trying to build a CreateView with a form that contains a button to lookup information via a GET request using HTMX. A user would encounter the form completely blank at first. Once they input a specific field (in this case a serial number), they can click the button that initiates the lookup/GET request. After the information is retrieved via the GET, I would like to update specific fields in the form with some of the information from the GET (essentially like an auto-complete). So far I have been able to build the initial CreateView (which is straightforward) and have been able to setup the button that does the HTMX GET request; I have also been able to retrieve the information needed but where I'm stuck is on being able to update/inject the values retrieved into specific fields from the form after the GET request. What are the steps I should take to handle that specific part? I have tried adding the form into the view that manages the HTMX get request and assigning some of the "initial" values, later having the form with the values defined as "initial" …
