Django Admin Dropdown Filtering: Show Exam Class Related Students in Student Assign Field
I'm working on a school management system using Django, and I'm currently facing an issue with customizing the behavior of dropdown fields in the Django admin interface. In my application, I have models for managing exams, students, and student results. Each exam is assigned to a subject, which is associated with a specific class and section. When I'm creating a student result entry in the admin panel, I want to ensure that the student_assign field only displays students who are part of the same class as the exam subject. More specifically, when I select an ExamAssign in the admin form, I want the related student_assign dropdown field to dynamically filter and display only those students who are associated with the same class as the selected exam subject. If I Select Class 10 here I want only to show the related class students (not only the section) here. I've tried implementing this using a custom admin form and overriding the __init__ method, but I'm encountering issues with getting the related students based on the selected exam's subject. Could anyone guide me through the correct way to achieve this functionality? I'd greatly appreciate any help or advice on how to properly filter … -
I cannot host Django app with docker-compose, and boilerplates request
I wish some guidelines, or maybe a tutorial, to develop a good Django app based on examples, its models and practices. At some point, I stumble on some in complexity exponential increment due many Django features. So far, I have been able to construct this app: https://github.com/trouchet/tarzan. I even wrote a Medium blog post based on ChatGPT. However, there is complexity on the way. Example: Command run docker compose up with docker-compose.yaml content as below and Dockerfile as on repository exits the container with logs as follows: version: '3' services: # Your Django application web: image: tarzan-image:latest container_name: tarzan-box ports: - "8000:8000" depends_on: - db db: image: postgres:13 container_name: tarzan-memory env_file: - .env ports: - "5432:5432" Traceback (most recent call last): File "manage.py", line 5, in <module> import django ModuleNotFoundError: No module named 'django' Traceback (most recent call last): File "manage.py", line 5, in <module> import django ModuleNotFoundError: No module named 'django' -
Make Django DB Transaction Idempotent on an External Call
I'm using a Django DB with a Postgres backend. Each user has a "balance" associated with their DB object, which is their current funds in the system. They can cash out the balance via gift cards, which is done by sending a POST request to Amazon's API. I perform two operations when the cash out their balance: Update the DB to set their balance to 0 Send a POST request to the Amazon API to generate a gift card for their balance If only one of these operations happen, that's very bad, for obvious reasons. I know you can use Transactions to make sure multiple database operations happen atomically -- is there a way to do something similar with a DB operation and an external call like this? -

Customize Form for User adding/editing in admin Wagtail
I have customized user profiles in Wagtail by adding fields (drm, cpm). How can I modify the form, or more specifically, the values in the form's lists based on the currently logged-in user and their permissions? Hello everyone, I have customized user profiles in Wagtail by adding fields (drm, cpm). How can I modify the form, or more specifically, the values in the form's lists based on the currently logged-in user and their permissions? For example, let's say you have extended the user profile model in Wagtail to include custom fields drm and cpm, and you want to dynamically populate a choice field in a form based on the user's role or permissions. Here's how you might approach this: # in models.py from django.db import models from wagtail.users.models import UserProfile class CustomUserProfile(UserProfile): drm = models.CharField(max_length=50, blank=True, null=True) cpm = models.CharField(max_length=50, blank=True, null=True) Next, you can create a custom form for a Wagtail admin page and override the form fields based on the user's profile: # in admin.py from wagtail.contrib.modeladmin.options import ModelAdmin from wagtail.contrib.modeladmin.views import CreateView, EditView from wagtail.contrib.modeladmin.helpers import PermissionHelper from .models import CustomUserProfile class CustomUserProfilePermissionHelper(PermissionHelper): def user_can_edit_obj(self, user, obj): # Customize this method to check if the user has … -

Django - Form Not Saving Image on Form Submission
For my current ModelForm for some reason all the fields get updated on a form submission as they are supposed to except for the image field. What’s the best solution to get this working with my current code? I think it’s because request.FILES isn’t getting handled correctly in my views.py file but not 100% sure. Side note: If i upload an image to the Django backend, the image field updates how it’s supposed to. This is only happening when there’s a form submission on the front end when the image field isn’t getting updated. Below is my code. Screenshots attached of the Django admin backend and the front end where the data is being displayed. Any help is gladly appreciated. Thanks! views.py def account_view_myaccount_edit(request): user_profile = User_Info.objects.filter(user=request.user) instance = User_Info.objects.get(user=request.user) user = request.user if request.method == 'POST': form = HomeForm(request.POST, request.FILES, instance=instance) if form.is_valid(): listing_instance = form.save(commit=False) listing_instance.user = user listing_instance.save() return redirect('myaccount_edit') # Redirect to a success page else: form = HomeForm(instance=instance) context = { 'user_profile': user_profile, 'form': form } return render(request, 'myaccount_edit.html', context) models.py class User_Info(models.Model): id = models.IntegerField(primary_key=True, blank=True) image = models.ImageField(default='default.jpg', upload_to='profile_pics', null=True, blank=True) user = models.OneToOneField(settings.AUTH_USER_MODEL,blank=True, null=True, on_delete=models.CASCADE) name = models.CharField(max_length=100) address = models.CharField(max_length=100) city … -
Votes not being counted in django poll
I'm working through the polls tutorial and I want to be able to have multiple questions on the same page and only press the vote button once. Right now, I don't get any errors but it is not counting the votes. I tried to write unittests to trace the error but am not sure how to replicate an html form either. In the future, I would also like other types of questions (like free text) mixed in and am not sure if I should create another app for the other question type or modify the Question and Choice in models.py. I saw some other examples but people warned against hardcoding questions/choices in the html but my form should end up remaining pretty static. models.py from django.db import models import datetime from django.utils import timezone class Question(models.Model): def __str__(self): return self.question_text question_text = models.CharField(max_length=200) pub_date = models.DateTimeField("date published") def was_published_recently(self): now = timezone.now() return now - datetime.timedelta(days=1) <= self.pub_date <= now class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) def __str__(self): return self.choice_text views.py from django.shortcuts import render # Create your views here. from django.http import HttpResponse, HttpResponseRedirect from django.template import loader from django.shortcuts import render, get_object_or_404, … -
Error while migrating from a SQLite database to a MySQL database in a Django Project
I'm trying to migrate all of the data in my SQLite database to a new MySQL database, to do so, I've been following the following steps (which I found in another question What's the best way to migrate a Django DB from SQLite to MySQL?). I've tried the following approaches: First I run a py manage.py dumpdata > datadump.json. Then, I change my settings.py file to use my new MySQL database. After that, I run a py manage.py migrate --run-syncdb And then I exclude contentType data by: python manage.py shell from django.contrib.contenttypes.models import ContentType ContentType.objects.all().delete() quit() And Lastly, I try to run a py manage.py loaddata datadump.json I've also tried to just run py manage.py dumpdata --exclude contenttypes --exclude auth.permission --exclude sessions --indent 2 > dump.json, followed by py manage.py loaddata dump.json. The problem is that, in both approaches, in the very last step, when I'm trying to load the data into my new database, the following error is raised: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte I've been trying to investigate what could prevent or fix this error but nothing has come up. Any help is appreciated. Thanks in advance. In case this … -

MS auth - Django adding an 'http' to my URI at callback
I am building a PoC for web applications using Django with Microsoft Authentication.

What is the neatest way to implement an optional update for a django web app?
I am creating an open-source web app using Django that anyone can install on their local machine, Heroku, etc. The most obvious way for the clients to get updates in the app is to ask them to pull the latest version from GitHub. Is there a cleaner, more elegant way to do this? For example, can we have a webpage (in the same Django project) which has a button to trigger an update from GitHub, while the web app is already running? TLDR: How to make a Django web app update its own code when it's told to do so? -

Testing a split API route in django rest framework using pytest
I'm trying to create a split of routes, creating two APIs. My idea is that my application works in two modes: normal, custom. Here is an example of my directory structure: - config - urls.py - api - custom - v1 - urls.py - normal - v1 - urls.py For the modes, I'm using environment variables. In my main urls.py I put it like this: [...] router = DefaultRouter() NORMAL = "normal" CUSTOM = "custom" if config.settings.MODE == NORMAL: urlpatterns = [ path("normal/v1/", include("api.normal.v1.urls")), ] elif config.settings == CUSTOM: urlpatterns = [ path("custom/v1/", include("api.custom.v1.urls")), ] My urls.py (normal): [...] router = DefaultRouter() urlpatterns = [ re_path(r"^", include(router.urls)), path("normal-example/", normal.normal-example, name="normal-example/"), ] And my urls.py (custom): [...] router = DefaultRouter() urlpatterns = [ re_path(r"^", include(router.urls)), path("custom-example/", custom.custom-example, name="custom-example/"), ] Ok. When I run and change, by env, works. Both in normal and custom. My problem is how to test this with pytest. I tried like this: @pytest.fixture(autouse=True) def mode_custom(settings): settings.MODE = "custom" def test_custom-example(mode_custom, client): resp = client.get("/custom/v1/custom-example/") assert resp.status_code == 200 Or using override_settings decorator.

Update value from a django view
I'm looking to update a value in my template whenever a change is made in a form. Here's the relevant template code snippet: <div> <p style="text-align: right;">Object count: {{ object_count }}</p> </div> <form action="{% url 'list_objects' %}" method="post"> <div id="target" class="fieldWrapper"> {{ form.target.errors }} {{ form.target.label_tag }} {{ form.target }} </div> </form> I'm handling the change event using JavaScript, and when the "target" value changes, I'm sending the new value to the view. This is the view code: class MyView(LoginRequiredMixin, FormView): template_name = "my_template.html" form_class = MyForm def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) object_count = MyModel.objects.all().count() context['object_count'] = object_count return context def post(self, request, *args, **kwargs): context = self.get_context_data(**kwargs) target_id = request.POST.get("target_id", None) target_obj = TargetModel.objects.filter(target_id=target_id).first() if target_id else None if target_obj: object_count = MyModel.objects.filter(club=target_obj).count() context["object_count"] = object_count return render(request, self.template_name, context) However, despite handling the target change, the counter for MyModel does not update as expected. Could you please advise on what I might need to fix to achieve the desired behavior?
