Django Crispy Forms with Tailwind CSS 4.0: Unwanted downward caret appears within the form
I'm using: Django 5.2.1 Tailwind CSS 4.0 crispy-tailwind 1.0.3 django-crispy-forms 2.4 I am using the Tailwind template pack, which is defined in my settings.py. When I render my form in my template 'concert_form.html' using crispy-forms, a large upside-down caret symbol appears after one of the fields in the middle of the form. If I comment out crispy-forms, then the form renders properly. Using the developer tools, with crispy-forms active, I can see there is a new in the code with an svg definition. That is not present with crispy-forms inactive. The only CSS I'm using is what is generated from the tailwind --watch command. Is there any way I can control crispy-forms to prevent this from happening? Here are the relevant code sections: concert_form.html html {% extends "_base.html" %} {% load tailwind_filters %} ... <div class="bg-white rounded-lg shadow-lg p-6"> <form method="post" class="space-y-6"> {% csrf_token %} {% form|crispy %} <div class="flex justify-end space-x-3 pt-4"> ... the balance of the code, navigation buttons to 'Cancel' or 'Submit' the form models.py python from django.db import models from django.urls import reverse class ConcertForm(forms.ModelForm): name = models.CharField(max_length=100) date = models.DateField() time = models.TimeField() venue = models.ForeignKey(Venue, on_delete=models.CASCADE) conductor = models.ManyToManyField(Conductor, blank=True) guests = models.ManyToManyField(Guest, blank=True) … -

Django ModelForm not prepopulating fields when updating instance – "This field is required" errors
I'm making a project in Django--UniTest. The idea is to let our university's faculty create and conduct online surprise tests on it.

Is it possible to use DRF's datetime picker and include the UTC offset for timestamps in the response JSON?
I am trying to use the Web browsable API in Django Rest Framework. I have objects with timestamp data in this format, "2025-05-08T22:02:58.869000-07:00". But the required format for Django's datetime picker does not support UTC offset or the last three significant digits for microseconds as shown below: I can trim the input data to satisfy the datetime picker like this: class MillisecondDateTimeField(serializers.DateTimeField): def to_representation(self, value): return value.astimezone().strftime("%Y-%m-%dT%H:%M:%S") + ".{:03d}".format( int(value.microsecond / 1000) ) But then the UTC offset is also missing from the timestamp in the POST/PUT response. { ... "start_datetime": "2025-05-08T22:02:58.869", ... } How can I make the value for "start_datetime" appear as "2025-05-08T22:02:58.869000-07:00" in the JSON response from POST/PUT while also using "2025-05-08T22:02:58.869" in the datetime picker? I have been researching online and trying for days. -
How can I set a javascript const to a value in a form element that could be either a dropdown select or a checked radio button?
I have an html form in a django site that is used for both add and update. If the form is for a new entry, I want the field estimateType to be radio buttons with three choices, one of which is checked by default. If the form is for an edit to an existing entry, I want the form widget to change to a select dropdown with additional choices to pick from. In the javascript in the onchange event, I need to know what the value of the estimateType field is. I can get it to work for select, or radio input, but not both. For example, what I have right now is: const estimateType = document.querySelector(input[name=estimateType]:checked).value; That works for a radio button but not the select dropdown. How can I use the same const declaration but account for heterogeneous form input types? -
Django filter objects which JSONField value contains in another model's JSONField values LIST of same "key"
I'm not sure if the title of this post made you understand the problem but let me explain: I have models: class ItemCategory(models.Model): name = CharField() class Item(models.Model): brand = CharField() model = CharField() category = ForeignKey(ItemCategory) attributes = JSONField(default=dict) # e.g {"size": 1000, "power": 250} class StockItem(models.Model): item = ForeignKey(Item) stock = ForeignKey(Stock) quantity = PositiveIntegerField() This models represent some articles on stock. Now I want to implement functionality to allow user create "abstract container" where he can input data and monitor how many of "abstract containers" may be produced based on stock remainings. Example: class Container(models.Model): name = CharField() class ContainerItem(models.Model): container = models.ForeignKey(Container) item_category = models.ForeignKey(ItemCategory) attributes = models.JSONField(default=dict) quantity = models.PositiveIntegerField() To handle aggregation I build a view: class ContainerListView(ListView): model = models.Container def get_queryset(self): items_quantity_sq = models.Item.objects.filter( item_category=OuterRef('item_category'), attributes__contains=OuterRef('attributes'), ).values('item_category').annotate( total_quantity=Sum('stock_items__quantity') ).values('total_quantity') min_available_sq = models.ContainerItem.objects.filter( container_id=OuterRef('pk') ).annotate( available=Coalesce(Subquery(items_quantity_sq), Value(0)) ).order_by('available').values('available')[:1] base_qs = super().get_queryset().annotate( # Attach the minimum available quantity across all items potential=Subquery(min_available_sq) ).prefetch_related( Prefetch( "items", queryset=models.ContainerItem.objects.all() .annotate(available=Subquery(items_quantity_sq)) .order_by("available"), ) ) return base_qs.order_by("potential") It works until ContainerItem attributes field contains a single value: {"size": 1000} but I want to allow user to input multiple values ("size": [1000, 800]) to find all Item objects which attributes … -
How to create a form Django (names and elements) from a column of a DataFrame or QuerySet column.?
How can I create a form - even if it's not a Django form, but a regular one via input? So that the names and elements of the form fields are taken from a column of a DataFrame or QuerySet column. I would like the form fields not to be set initially, but to be the result of data processing - in the form of data from a column of a DataFrame or QuerySet column. The name of the form fields to fill in from the data in Views. Maybe send a list or a single DataFrame or QuerySet to the template via JINJA? from django import forms # creating a form class InputForm(forms.Form): first_name = forms.CharField(max_length = 200) last_name = forms.CharField(max_length = 200) roll_number = forms.IntegerField( help_text = "Enter 6 digit roll number" ) password = forms.CharField(widget = forms.PasswordInput()) from django.shortcuts import render from .forms import InputForm # Create your views here. def home_view(request): context ={} context['form']= InputForm() return render(request, "home.html", context) <form action = "" method = "post"> {% csrf_token %} <table> {{ form.as_table }} </table> <input type="submit" value="Submit"> </form> How to create a form Django (names and elements of the form fields) from a column of a … -
Django Application: Model field or app for conditions
I'm currently planning a Django-application that runs jobs regurarly based on conditions. Regurarly the application should check if any of the jobs has the conditions met and should run those with positive outcome. Think of the conditions of an automation in HomeAssistant as an example of what I'm trying to construct. I also want to include "OR" or "AND" conditions to link multiple conditions together. Ideally a frontend component should allow for comfortable editing these conditions. As I already initiated to implement it as a JSON-Field with a custom syntax that is checked in a method inside the model. But it seems to be such a common problem to me, that I'm sure someone has already developed an app for that. But unfortunately I was not able to find anything in that direction - maybe because of lack of words. Has anybody a pointer to for an application? -

Django allauth social account autoconnect
I got a Django-allauth backed site with legacy local users most of which eventually should be connected to social login upon their next sign-in, whenever that might be. Only supported social provider is Microsoft Graph. All emails from the provider are to be treated as verified, and in case it matches any existing user, these are also treated as the same user without further verification. Relevant allauth settings as below: ACCOUNT_LOGIN_METHODS = {"email"} ACCOUNT_USER_MODEL_USERNAME_FIELD = None SOCIALACCOUNT_PROVIDERS = { "microsoft": { "EMAIL_AUTHENTICATION_AUTO_CONNECT": True, "EMAIL_AUTHENTICATION": True, "EMAIL_VERIFICATION": False, "VERIFIED_EMAIL": True, "APPS": [ #client id, secret masked ] } } Signing in with a social account that has its e-mail registered (and which should be connected upon login) works, but no connected social account is created. Signing in with a social account without an existing user creates a new user with the respective social account as expected and desired. If I write my own hooks to customized SocialAccountAdapter (or add receivers to allauth's signals), I can achieve my target, but at least according to my interpretation of the allauth documentation, this seems a bit hacky and does not seem like the intended way in the current version. Allauth version is 65.7.0 -

Trying to deploy Django web app on PythonAnywhere, "no python application found"
I have a Django web app (Python 3.11) that runs on Azure, and I'm trying to migrate it to PythonAnywhere. I've followed the setup instructions. The web page itself says "Internal Server Error". The error log is empty. The server log has the following: --- no python application found, check your startup logs for errors --- as well as a most peculiar 'import math' error (see below) that may be relevant. (Starting python in my virtual environment, I'm unable to import anything there either, so possibly a PYTHONPATH or other env problem?) Where are these startup logs? I assume something is just pointing to the wrong place, I just need the information to work out what.

Scroll and nesting issues when rendering multiple reports with Leaflet on a single HTML page
I'm generating a combined report in Django by looping through several database entries and rendering the same HTML template multiple times, each with different data. The template includes Leaflet maps and some inline scripts. The problem is: when I combine the reports into a single page, the layout breaks — it looks like the reports are either nested inside each other or overlapping. I also see multiple scrollbars (one inside another), which shouldn't happen. This only occurs when I render several reports together. Each individual report works fine on its own. The issue only appears when I generate them together in a loop. Any help or direction would be appreciated. -
Orderby and distinct at the same time
I have tabels like this id sku 1 C 2 B 3 C 4 A Finally I want to get the raws like this. 1 C 2 B 4 A At first I use distinct queryset = self.filter_queryset(queryset.order_by('sku').distinct('sku')) It depicts the raw like this, 4 A 1 C 2 B Then now I want to sort this with id, queryset = queryset.order_by('id') However it shows error like this, django.db.utils.ProgrammingError: SELECT DISTINCT ON expressions must match initial ORDER BY expressions LINE 1: SELECT DISTINCT ON ("defapp_log"."sku") "d... -
Django: Applying Multiple Coupons Adds Discounts Incorrectly Instead of Sequentially
I'm building a Django e-commerce checkout system where multiple coupon codes can be applied. Each coupon can be either a fixed amount or a percentage. Coupons are stored in a Coupon model, and applied coupons are tracked in the session. Problem: Suppose I have a product costing ₹30,000. When I apply the first coupon CODE001 (10% discount), the total should become ₹27,000. Then I apply the second coupon CODE002 (90% discount), which should apply on ₹27,000, making the final total ₹2,700. But currently, both coupons are being applied independently on the full cart total of ₹30,000, not on the discounted total. So the discount appears as ₹30,000 for both coupons. My Current View Logic: In the view, I'm looping over all the applied coupons like this: if 'applied_coupon_codes' in request.session: applied_coupon_codes = request.session['applied_coupon_codes'] applied_coupons = [] for code in applied_coupon_codes: try: coupon = Coupon.objects.get(code__iexact=code, is_active=True) if coupon.valid_to >= timezone.now() and cart_total_amount >= float(coupon.min_cart_total): applied_coupons.append(coupon) if coupon.discount_type == 'percent': percent_discount = (cart_total_amount * coupon.discount_value) / 100 if coupon.max_discount_value is not None: percent_discount = min(percent_discount, coupon.max_discount_value) coupon_discount += percent_discount else: coupon_discount += float(coupon.discount_value) except Coupon.DoesNotExist: continue Here, cart_total_amount is used for each coupon, so all coupons calculate their discount on the full … -
Django Static Files Not Uploading to Digital Ocean Spaces Despite Correct Configuration
I'm having issues with Django's static files not being uploaded to Digital Ocean Spaces (S3-compatible storage) in production since I've upgraded to Django 5.2 from 4.2. As part of this upgrade I also updated python, boto3 and django-storages. The collectstatic command appears to run successfully locally, but files are not being updated in the Spaces bucket. Additionally, some static files (particularly CSS) are being served as downloads instead of being rendered in the browser.

ModuleNotFoundError: No module named 'rest_framework_simplejwt'. I have tried the methods listed in other posts
I am building an authentication system with the JWT token. I have done pip install djangorestframework-simplejwt and pip install --upgrade djangorestframework-simplejwt in my virtual environment. This is my installed-apps in settings.py: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'rest_framework_simplejwt', 'rest_framework_simplejwt.token_blacklist', ] And here is my urls.py: from django.contrib import admin from django.urls import path, include from api.views import CreateUserView from rest_framework_simplejwt.views import TokenObtainPairView, TokenRefreshView urlpatterns = [ path("admin/", admin.site.urls), path("api/user/register",CreateUserView.as_view(), name="register"), path("api/token/",TokenObtainPairView().as_view(),name="get_token"), path("api/token/refresh/",TokenRefreshView.as_view(),name="refresh"), path("api-auth/", include("rest_framework.urls")) ] I have these on my pip list: django-rest-framework 0.1.0 djangorestframework 3.16.0 djangorestframework-jwt 1.11.0 djangorestframework_simplejwt 5.5.0 pip 25.1.1 PyJWT 1.7.1 python-dotenv 1.1.0 pytz 2025.2 rest-framework-simplejwt 0.0.2 But when I run the code, it still says ModuleNotFoundError: No module named 'rest_framework_simplejwt'. I have checked the documentation and other posts. Is there anything else I am missing?
