Wagtail 2.10 update breaks SVGs
I have an old codebase written using wagtail at work and I have to update the wagtail version from 2.9 to 2.10. I tried this thing and the icons from the cms literally break. They do not show up at all. Looks like the 2.10 update migrates the font icons to svg icons. The HTML looks good, but there is no svg path to reference to for some reason. <svg class="icon icon-folder-open-inverse icon--menuitem" aria-hidden="true"> :before <use href="#icon-folder-open-inverse"></use> </svg> From other examples, looks like I should have the svgs with paths defined at the top of the body tag, but there are none. Tried to rerun collectstatic, but with no success. Does anyone have any idea why or how to solve this? -
Django get authors in serie through book-object
For a hobby project I am building a django-app that displays the books in a private collection. I have 3 models relevant to this question: Serie, Book and Author: from django.db import models class Author(models.Model): pass class Book(models.Model): authors = models.ManyToManyField(Author) class Serie(models.Model): books = models.ManyToManyField(Book) If I have a Serie-object, what is a good way to get all authors in the serie? (Some series in the collection have books written by different authors) -
Please explain the essence of the task related to Django models
Good afternoon! I ask for help in explaining the task of using DRF. The task is to develop an authorization and news server. I basically understand what I need to do, but here are some steps from the explanation I don't understand. I need to have a Users model (which has a username field and an encrypted password field). I can't figure out if I need to use the built-in Django - User model or create this model myself. It is also written in the explanation that admin users may not overlap with users in the Users table I tried to create my own Users class, but I couldn't figure out which type of field to choose for the password. -
Django Model VIewSet overriding
Models class Inventory(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE) product_name = models.CharField(max_length=100) unit_price = models.DecimalField(max_digits=8, decimal_places=2) quantity = models.PositiveIntegerField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return f"{self.product.name} - {self.quantity}" class InventoryHistory(models.Model): inventory = models.ForeignKey(Inventory, on_delete=models.CASCADE) quantity_change = models.DecimalField(max_digits=8, decimal_places=2) timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return f"{self.product.name} - {self.quantity_change} ({self.timestamp})" Serializers class InventoryHistorySerializer(serializers.ModelSerializer): class Meta: model = InventoryHistory fields = '__all__' class InventorySerializer(serializers.ModelSerializer): category = CategorySerializer() class Meta: model = Inventory fields = '__all__' ViewSets class InventoryViewSet(viewsets.ModelViewSet): queryset = Inventory.objects.all() serializer_class = InventorySerializer class InventoryHistoryViewSet(viewsets.ReadOnlyModelViewSet): queryset = InventoryHistory.objects.all() serializer_class = InventoryHistorySerializer I'm working with above code. The idea is, When Some changes are made in Inventory, the InventoryHistory gets automatically updated with a new record. My main confusion is, having two different serializers. How can i override viewsets and manage these two different serializers. -
Django - Show a simple gallery in the template
I have these models: class Car(models.Model): brand = models.CharField(max_length=255) model = models.CharField(max_length=255) class CarImage(models.Model): car = models.ForeignKey(to=Car, on_delete=models.CASCADE) image_upload = models.ImageField(upload_to="images", blank=True, null=True) From my DetailView to the template I am passing the Car instance's data and also the CarImage instances belonging to the specific Car. How do I create a simple, but responsive gallery of images from CarImage instances if I shall not use JavaScript frameworks like Vue, React or anything else? I am looking to get a gallery like these ones: https://photoswipe.com/ or https://www.lightgalleryjs.com/ I was not able to get them running either because of some weird JavaScript issues, or, because they require some license to be purchased. Thank you -

Error when Making Migration for Django Project
When I completed writing my models, one models, I used GenericForeignKey. Here is the code from django.db import models from django.contrib.contenttypes.models import ContentType from django.contrib.contenttypes.fields import GenericForeignKey # Create your models here. class Tag(models.Model): label = models.CharField(max_length=255) class TaggedItem(models.Model): # what tag applied to what object tag = models.ForeignKey(Tag, on_delete=models.CASCADE) content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_type = GenericForeignKey() but I counter this error which I could not solve. SystemCheckError: System check identified some issues: ERRORS: like.LikedItem.content_type: (contenttypes.E003) 'LikedItem.content_type' is not a ForeignKey. HINT: GenericForeignKeys must use a ForeignKey to 'contenttypes.ContentType' as the 'content_type' field. tags.TaggedItem.content_type: (contenttypes.E003) 'TaggedItem.content_type' is not a ForeignKey. HINT: GenericForeignKeys must use a ForeignKey to 'contenttypes.ContentType' as the 'content_type' field. Your support is appreciated I tried multiple solution that I found through my research in the Internet, but none of those fixed the issue. One of the change I did is: content_type = GenericForeignKey('content_type', 'object_id') -
How to apply Count on prefetched queryset in django?
To demonstrate my use case, I've devised a similar but simpler setup as follows: class Student(models.Model): name = models.CharField(max_length=100) def __str__(self): return self.name class Routine(models.Model): owner = models.OneToOneField(Student, on_delete=models.CASCADE, related_name='routine') def __str__(self): return f"Routine | {self.owner}" class Activity(models.Model): title = models.CharField(max_length=100) is_active = models.BooleanField(default=True) routine = models.ForeignKey(Routine, on_delete=models.CASCADE, related_name='activities') def __str__(self): return f"{self.title} | {'Active' if self.is_active else 'Expired'} | {self.routine.owner}" routines = Routine.objects.all().prefetch_related( Prefetch('activities', queryset=Activity.objects.filter(is_active=True)) ) The queryset above will retrieve all routines and their related active activities. However, some routines might not have any associated active activities, and in such cases, their activities will be empty. routines = Routine.objects.all().prefetch_related( Prefetch('activities', queryset=Activity.objects.filter(is_active=True)) ).annotate(active_activity_count=Count("activities")).exclude(active_activity_count=0) I updated the queryset to filter out routines with empty activities after prefetching active activities but this doesn't work. It seems like Count counts actual activities instead of prefetched activities. Is there a way to make Count count prefetched activities? -
How to install chormadb on AWS EC2?
Pythoners. I need an urgent help with AWS and Django. I created AWS EC2 instance and installed django using pip install django. But when I try to install chromadb, it freezes on the stage of installing hnswlib. What is the reason? This is my second time to deploy on AWS EC2. But at the first time, my client created instance and I only used it. And there was no issue. But this time, I created instance and tried. I felt the speed is very slower than before. Are there any options of the speed of instance? Thanks -
Invalid date error with django DateField using generic UpdateView and bootstrap_datepicker_plus
Django noob but been wrangling with this for a while. When attempting to update or create a new ticket on my dev server I encounter an error beneath the field stating 'Enter a valid date.'. The relevant details models.py class Ticket(models.Model): date_of_complaint = models.DateField() ticket_new.html template <!--templates/ticket_edit--> {% extends "base.html" %} {% load crispy_forms_tags %} {% block content %} <h1>Edit</h1> <form action="" method="post">{% csrf_token %} {{ form.media }} {{ form|crispy }} <button class="btn btn-info ml-2" type="submit">Update</button> </form> {% endblock content %} views.py class TicketCreateView(LoginRequiredMixin, CreateView): model = Ticket template_name = "ticket_new.html" fields = ( "title", "date_of_complaint", "author", "customer", "description", "account_manager", ) def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def get_form(self): form = super().get_form() form.fields["date_of_complaint"].widget = DateTimePickerInput() return form settings.py I believe the root of the issue is that the field was formerly a DateTimeField before I realized I did not want the time, only the date. I changed the model to DateTime and ran makemigrations and migrate, then changed the settings of bootstrap date picker plus to only include mm/dd/yyyy, but when I click on a date within the widget it still brings a timestamp. settings.py BOOTSTRAP_DATEPICKER_PLUS = { "options":{ "showTodayButton": True, }, "variant_options": { "date": { "format": "MM/DD/YYYY", … -
How to set a dictionary or list to a cookie and get it properly in Django?
I could set a dictionary or list to a session and get it properly as shown below: # "views.py" from django.http import HttpResponse def my_view(request): request.session['teacher'] = {'name': 'John', 'age': 36} print(request.session['teacher']) # {'name':'John','age':36} print(request.session['teacher']['name']) # John print(request.session['teacher']['age']) # 36 request.session['student'] = ['David', 21] print(request.session['student']) # ['David', 21] print(request.session['student'][0]) # David print(request.session['student'][1]) # 21 return HttpResponse("Test") But, I couldn't set a dictionary or list to a cookie and get it properly as shown below: # "views.py" from django.http import HttpResponse def my_view(request): response = HttpResponse('Test') response.set_cookie('teacher', {'name': 'John', 'age': 36}) response.cookies['student'] = ['David', 21] return response # "views.py" from django.http import HttpResponse def my_view(request): print(request.COOKIES['teacher']) # {'name': 'John', 'age': 36} print(request.COOKIES['teacher']['name']) # Error print(request.COOKIES['teacher']['age']) # Error print(request.COOKIES['student']) # ['David', 21] print(request.COOKIES['student'][0]) # [ print(request.COOKIES['student'][1]) # ' HttpResponse("Test") So, how can I set a dictionary or list to a cookie and get it properly in Django? -
How do we add functions in existing Django views?

Django shuts up after pandas DataFrame.loc search by index and column combination
I am using pandas to read csv and create Dataframe with columns pilot and avarage_lap_time.

How to configure dev environment with multiple containers from a git repository?
I have a full-stack application repository with the following structure: .git <- Note git repository /front-end /back-end <- python back-end /docker -front-end-dockerfile -back-end-dockerfile -front-end-setup.sh -back-end-setup.sh docker-compose.yaml After running docker compose build and docker compose up -d in the repository's root level, I get 2 containers: front-end-dev back-end-dev Both work fine, however, when building, both the front-end and the back-end get split up between both containers. I want to develop inside each container and still want git to track changes, despite each container containing either the back-end or front-end directory. Currently I see two options: develop outside the container, which mean I won't have a working interpreter for intellisense/pylance. develop in the container, which means I won't have git working. Is there a way to have both 1) git and 2) intellisense/pylance working? Any suggestions and recommendations on how to develop using this configuration would also be appreciated. -
Is the Basic File Upload example in the Django documentation correct?
I'm using python 3.10.5 with django 4.2.2. The djangoproject documentation for a Basic File Upload has the following example for uploading a file: Consider a form containing a FileField: forms.py from django import forms class UploadFileForm(forms.Form): title = forms.CharField(max_length=50) file = forms.FileField() views.py from django.http import HttpResponseRedirect from django.shortcuts import render from .forms import UploadFileForm # Imaginary function to handle an uploaded file. from somewhere import handle_uploaded_file def upload_file(request): if request.method == 'POST': form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): handle_uploaded_file(request.FILES['file']) return HttpResponseRedirect('/success/url/') else: form = UploadFileForm() return render(request, 'upload.html', {'form': form}) This is my upload.html: <!DOCTYPE html> <html> <head> <title>File Upload</title> </head> <body> <h1>File Upload</h1> <form method="post" enctype="multipart/form-data"> {% csrf_token %} <input type="file" name="file" required> <button type="submit">Upload</button> </form> </body> </html> When I run that code, it fails the... if form.is_valid() ...test in views.py because "title" is empty, but it's defined as required in the forms.py. If I simply comment out the... title = forms.CharField(max_length=50) ...line from forms.py, then it works fine, so what is that "title = forms.CharField(max_length=50)" line for in forms.py? -

How long does it take to install chromadb on Ubuntu?
I have developed a django project and am trying to deploy to AWS EC2 Instance.

Building wheels for collected packages: hnswlib Building wheel for hnswlib (pyproject.toml) ... \ It doesn't give any error but no progress. How to handle this? Should I wait?

Now I created the Instance with myself. Are there any kind of settings about Instance? Thanks -

Integrating Veracode logging formatter library into Django project
there! I'm currently working on resolving a vulnerability issue reported by Veracode, specifically CWE 117 (Improper Output Neutralization for Logs). To address this issue, I need to implement the Veracode logging formatter library available at logging-formatter-anticrlf in my Django project. In Django, there is a configuration file called settings.py where the logging behavior for the application is defined using formatters, handlers, and loggers. Here's an example of the configuration: # Logging LOGGING = { 'version': 1, 'formatters': { 'verbose': { 'format': '{levelname} {asctime} {filename}:{lineno} {message}', 'style': '{', }, 'simple': { 'format': '{levelname} {message}', 'style': '{', }, }, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'formatter': 'verbose', }, 'file': { 'level': 'DEBUG', 'class': 'concurrent_log_handler.ConcurrentRotatingFileHandler', 'filename': os.path.join(BASE_DIR, '..', '..', 'log-debug.log'), 'maxBytes': 1024 * 1024 * 1024, 'backupCount': 365 * 7, 'formatter': 'verbose', }, }, 'root': { 'handlers': ['console', 'file', 'errorfile'], 'level': 'DEBUG', }, 'loggers': { 'root': { 'handlers': ['console', 'file', 'errorfile'], 'propagate': True, 'level': 'DEBUG', }, 'django.request': { 'handlers': ['console', 'file', 'errorfile'], 'propagate': False, 'level': 'DEBUG', }, 'django.server': { 'handlers': ['console', 'errorfile'], 'propagate': False, 'level': 'DEBUG', }, 'webportal': { 'handlers': ['console', 'file', 'errorfile'], 'propagate': False, 'level': 'DEBUG', }, } } In each module of the Django application, the LOGGER is instantiated … -
Reduce database hit when using django-taggit and mymodel.tags.all in a template
I'm using django-taggit in Django 3.2 and can't figure out how to prevent it from hitting the database for every object in a list view template. Here's how I'm using it: class Quest(TagsModelMixin, models.Manager): # etc. In a ListView html template, I am displaying all Quest objects and their tags like this: {% for obj in quest_queryset %} {{obj.name}}: {{ obj.tags.all }} {% endfor %} At first, this was hitting the DB twice per object. I found that if I prefetch_related I could remove half of them: quest_queryset = quest_queryset.prefetch_related('tags') But I'm still getting one hit per object. How can I eliminate this repetition? Here's the offending query as shown by django-debug-toolbar, when there are 5 Quest objects. -

Is this even legal? Is the API badly designed (I'm wondering). What can I do here? I can't seem to wrap my head around how to achieve this using QueryDict.
