DRF bulk insert crashes on serializer.data: too many values to unpack (expected 2)
I have two serializers and I use list_serializer_class for bulk inserts. I use viewset and in my viewset @action(methods=['post'], detail=False, url_path='bulk') def bulk_create(self, request): serializer = self.get_serializer(data=reusables, many=True) ......... self.perform_create(serializer) The data is successfully inserted into the database but when I try to get the data from the serializer headers = self.get_success_headers(serializer.data) return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers) I get the error: too many values to unpack (expected 2) probably beucase it's trying to decode the data using the first serializer and not the list_serializer_class These are my serializers: class ItemsSerializer(object, serializers.ListSerializer, serializers.ModelSerializer): name = serializers.CharField(source='display_name', max_length=90) def update(self, instance, validated_data): pass def create(self, validated_data): items = [Item(**item) for item in validated_data] return Item.objects.bulk_create(items) class Meta: model = Item fields = ('id', 'displayName', 'content', 'creationDate', 'modificationDate', 'ownerName', 'site', 'lastEditorName', 'uuid') class ItemSerializer(object, serializers.ModelSerializer): name = serializers.CharField(source='display_name', max_length=90) class Meta: list_serializer_class = ItemsSerializer model = ReusableBlock fields = ('id', 'name') -
How to resolve: ModuleNotFoundError: No module named 'leadsagents' in Django
I know the is a lot of similar questions but I've tried different solutions from stack overflow, the web and YouTube. This happened after making migrations to my db.sqlite3 file it worked until I tried adding new agents. Any help will be appreciated. Also I don't even know which files to upload because the is no module names leadsagent in my project.

Tpye hints for mixins that reference attributes of a third-party base class
I'm trying to add type hints to a mixin class that is to be used alongside an external, third-party class. That is, the mixin relies on members of the third-party class. For example, a mixin for a Django form: # mixin_typing.py from django import forms class SuffixFormMixin: suffix: str def add_suffix(self, field_name: str) -> str: # prefix is an attribute of forms.Form return f"{self.prefix}__{field_name}__{self.suffix}" class SuffixForm(SuffixFormMixin, forms.Form): pass Understandably, mypy will complain about the add_suffix method: "SuffixFormMixin" has no attribute "prefix" IDE (PyCharm) will also throw a warning: Unresolved attribute reference 'prefix' for class 'SuffixFormMixin' Question: Is there any "easy" solution that lets the mixin understand that self contains attributes/methods of forms.Form? Here is a github issue that addresses this, but sadly didn't go anywhere: https://github.com/python/typing/issues/246 Maybe some kind of typing object or other mypy-fu that acts as a promise to the mixin class that the future "partner class" has the members that the mixin is using? Attempted solutions The suggestions I have found so far all have drawbacks: Type-hinting self to the partner class (works for mypy: ✅, doesn't work for IDE: ❌) I have seen suggestions to type hint self to the class that the mixin will later … -
Why are multiple bootstrap modals being rendered after HTMX hx-get?
I have a Django page using HTMX to populate some bootstrap styled tabs (Members, Events and Contacts). 'hx-get' is used to load the desired page content into the DOM. On the Members page, I have a button that opens a bootstrap modal form when clicked for the user to add a member. The issue is that the number of times the modal is rendered to the DOM when the button is clicked corresponds to the number of times the Members content is loaded. If the Members page is rendered twice (navigating from Members tab to Events tab, then back to Members), two modals appear in the DOM and so on. I initially thought it may be caused by the modal form also being rendered with hx-get. However, I've replaced the modal form with a basic modal on the same page and the issue persists. Why is only the modal being rendered multiple times? The members page is only being rendered once. Tabs code: <div class="container"> <div class="row"> <div class="nav flex-column nav-pills me-3 col" role="tablist" aria-orientation="vertical" id="tabs" hx-target="#tab-contents" _="on htmx:afterOnLoad take .active for event.target"> <button type="button" id="members-btn" role="tab" aria-controls="tab-contents" aria- selected="true" hx-get="{% url 'members' %}" class="nav-link active"> Members </button> <button type="button" … -
django "import excel to database" libraries

Django CSRF protection for cross site post requests
I am using react as frontend and using django for backend. When I host both the frontend and backend on localhost, everything works fine and X-CSRFTOKEN is sent perfectly. const instance = axios.create({ withCredentials: true, withXSRFToken: true, xsrfHeaderName : 'X-CSRFTOKEN', xsrfCookieName : 'csrftoken' }); My DJango settings are (taken from this answer Django - check cookies's "SameSite" attribute): CORS_ALLOW_CREDENTIALS = True CSRF_COOKIE_SECURE = True SESSION_COOKIE_SECURE = True CSRF_COOKIE_SAMESITE = "None" SESSION_COOKIE_SAMESITE = "None" but when my frontend (firebase )and backend(eks aws) are hosted on different subdomains, I receive a 403 Forbidden Error. It should return a 201 ccreated response but instead it is returning a 403 error, CSRF verification failed. Request aborted. -

Problem with redis/celery, why do some tasks triggers an Errno 111 but others don't?
I am currently building a web app with django. I am using redis and celery to send emails for various purposes. I have a background worker checking my db for mails to send every 5s (very short for testing purposes),if it finds mails flagged as unsent, then it sends them, this part works as intended.

Errno 111 Connection refused: Issue with rendering PDF with xhtml2pdf in Django on a Linux server with static files images
I've successfully deployed my Django project on a Linux server, but I'm encountering an issue when trying to print PDF reports. The images located in the static folder are causing errors during the rendering process. <img class="logo" src="http://{{host}}/static/logo_1.jpeg"> enter image description here It's worth noting that I can access these images through their respective URLs, but I'm getting a connection refused error with xhtml2pdf. I'm curious if there might be some Apache2 configuration settings that I may have overlooked that could be causing this connection issue in the context of xhtml2pdf. Any insights or guidance on potential Apache2 configurations would be greatly appreciated. My goal is to determine if there's any permission or configuration issue with Django URLs that I might have overlooked. What doesn't make much sense to me is that I can view the images through the URL, but they can't be rendered in a PDF. Does this library use a different type of connection when importing images for PDF rendering? -
How to get status code for all urls in Django app
Есть ли возможность в Django 5.0 получить все ответы сервера для url адресов зарегистрированных в приложении? Или возможность передать url адрес и получить код ответа, но для уже авторизованного пользователя. Я пробовала использовать библиотеку requests. Без авторизации код ответа не является валидным, т.к в моем приложении все url адреа доступны только после авторизации. В зависимости от назначенных бизнес ролей, разным пользователям доступны разные url адреса. Я бы хотела иметь возможность заранее сформировать список доступных url адресов для авторизованного пользователя. Для авторизации и аутентификации используется Active Directory по протолку LDAP и в самом приложении нет паролей пользователя. -

Django models with hard coded model fields in filtersets
This question is about filtering. But to explain here is some supporting facts... There is a concept in my program of objects being virtual or not virtual. Using rest_framework I have two models in my models.py: So to do that I have tried: class ModelA(models.Model): @property def is_virtual(self): return False class ModelB(ModelA): @property def is_virtual(self): return True So ModelB inherits ModelA. And ALL ModelA objects are NOT virtual, and ALL ModelB objects ARE virtual. Instead of adding this to the database where the column is always True for ModelAs and False for ModelBs I would like to hardcode it in the model class and supporting classes. In my serializers.py I have: class ModelSerializer(serializers.ModelSerializer): is_virtual = serializers.SerializerMethodField() def get_is_virtual(self, obj): return obj.is_virtual All this above basically works UNTIL I want to filter search on is_virtual. In my filters.py: class ModelFilterSet(filters.FilterSet): is_virtual = filters.BooleanFilter(method='filter_is_virtual') def filter_is_virtual(self, queryset, name, value): if value: return queryset.filter(is_virtual=True) else: return queryset.filter(is_virtual=False) Then when I GET http://localhost:8080/api/modela/?is_virtual=false I get: Internal Server Error: /api/modela/ Traceback (most recent call last): File "D:\projects\my_app\venv\lib\site-packages\django\core\handlers\exception.py", line 55, in inner response = get_response(request) File "D:\projects\my_app\venv\lib\site-packages\django\core\handlers\base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "D:\projects\my_app\venv\lib\site-packages\django\views\decorators\csrf.py", line 65, in _view_wrapper return view_func(request, *args, **kwargs) … -
Django AdminSite overrides admin template
I tried to complete Django tutorial and it says that you can override Django's templates with providing example on how to change title of admin page (here). When I tried, nothing changed, so I went to google and investigate. My project structure currently looks like this (django_trial is my project's name): - django_trial/ - django_trial/ - polls/ - ... - templates/ - admin/ - base_site.html (copy of template from Django with modified title) - base_site.html (copy of admin/base_site.html from above, just in case) - venv I tried to see what template it loads, so I put code below in my polls/admin.py from django.template.loader import get_template a = get_template("admin/base_site.html") print(repr(a.origin)) and it printed <Origin name='/home/my_username/Projects/django_trial/templates/admin/base_site.html'>, so my template override seems to work somewhat correctly. Then I tried modifying actual library files and changing original .../venv/lib/python3.10/site-packages/django/contrib/admin/templates/admin/base_site.html didn't do anything as well. In the end, I managed to change admin page title when I modified .../venv/lib/python3.10/site-packages/django/contrib/admin/sites.py. There is a class AdminSite and it has the line site_header = gettext_lazy("Django administration") Seems it has top priority, so its modification actually changed admin page title. What could I do wrong so this line always take priority? -
My models are not showing in Django Admin after OTP Token implementation
I wanted to secure my Django Admin so I followed the steps in here and I implemented django-otp to the my website. The token works fine. I can login my admin page safely but my models doesn't show up in my admin page. For example: Before the OTP Implementation I was able to post a new blog or something but now I cant at all. There are nothing about blogs in my admin. I am logging as a superuser and I tried to create another superuser and logging but it didn't change. I think this error might be caused by the admin.py file configurations, but I'm not sure. Here is my urls.py from django.contrib import admin from django.urls import path, include, re_path from django.conf import settings from django.conf.urls.static import static from django.contrib.staticfiles.urls import staticfiles_urlpatterns # new from django.conf import settings from django.views.static import serve from django.contrib.auth.models import User from django_otp.admin import OTPAdminSite from django_otp.plugins.otp_totp.models import TOTPDevice from django_otp.plugins.otp_totp.admin import TOTPDeviceAdmin class OTPAdmin(OTPAdminSite): pass admin_site = OTPAdmin(name='OTPAdmin') admin_site.register(User) admin_site.register(TOTPDevice, TOTPDeviceAdmin) urlpatterns = [ path('admin/', admin_site.urls), path('', include('pages.urls')), path('', include('portfolio.urls')), path('', include('services.urls')), path('', include('blog.urls')), re_path(r'^media/(?P<path>.*)$', serve, {'document_root': settings.MEDIA_ROOT}), re_path(r'^static/(?P<path>.*)$', serve, {'document_root': settings.STATIC_ROOT}), ] Here is an example of my admin.py from django.contrib … -
How to properly scope validator function in parent class for use in child class
I'm trying to use validators, but I'm having a mysterious issue with using validators in a parent/child class. Right now I've created a base class for all media in my project; all media in this model need a name and a thumbnail: class BaseMedia(BaseModel): def validate_thumbnail(image_obj): validate_image_file_extension(image_obj) dimensions = [image_obj.width, image_obj.height] if dimensions[0] != 400 or dimensions[1] != 400: raise ValidationError( "Thumbnail dimensions must be 400 x 400; uploaded image is %s x %s" % (dimensions[0], dimensions[1]) ) media_title = models.CharField( max_length=25, verbose_name="Title (25 char)", null=True ) thumbnail = models.ImageField( null=True, verbose_name="Thumbnail (400 x 400 px)", upload_to="microscopy/images/thumbnails", validators=([validate_thumbnail],), ) and then I have a child class that inherits and implement the core media itself; for example: class MicroscopyMedia(BaseMedia): def validate_image(image_obj): validate_image_file_extension(image_obj) dimensions = [image_obj.width, image_obj.height] if dimensions[0] != 1920 or dimensions[1] != 1070: raise ValidationError( "Image dimensions must be 1920 x 1070; uploaded image is %s x %s" % (dimensions[0], dimensions[1]) ) media = models.ImageField( null=True, verbose_name="Media (1920 x 1070 px)", blank=True, upload_to="microscopy/images", validators=[validate_image], ) The idea being that all models will need a thumbnail, but within the child class I have a specific validator for each individual media type. However, when I try to make this migration, I get … -
django-registration class overriding
Because I need to add a captcha(django-recaptcha) to the registration form I want to override the RegistrationForm class from the django-registration module. I am using: django-registration==3.3 django==4.1 python(3.10) I've tried some options has shown below. forms.py from django_registration.forms import RegistrationForm class MyRegistrationForm(RegistrationForm): age = forms.IntegerField() class Meta(RegistrationForm.Meta): fields = RegistrationForm.Meta.fields + ['age'] urls.py from .forms import MyRegistrationForm from django_registration.backends.activation.views import RegistrationView path('accounts/register/', RegistrationView.as_view(form_class=MyRegistrationForm), name='registration_register') registration_form.html <form method="post" action="."> {% csrf_token %} {{ form.as_p }} <input type="submit" value="{% trans 'Submit' %}" /> </form> Nothing overrides the form. I don't understand why. Same thing for the RegistrationView. I can't override it for some reason. I've been arround these for a while now. Probably am missing something obvious by now. Help is appreciated. Thank you. -
How to get items stacked in a row together in a column thats col-3
I am trying to stack all the items under one another if there is more than one. I am using Django and currently its reproducing a new col-3 for each new item. I have tried bootstrap d-flex flex-wrap, however this is not working. <div class="col-12 col-lg-6"> <p>Order History</p> {% for order in orders %} <div class="row"> <div class="col-3"> <p>Date:</p> </div> <div class="col-3"> <p>Grand Total:</p> </div> <div class="col-3"> <p>Order Number:</p> </div> <div class="col-3"> <p>Items:</p> </div> </div> <div> <div class="row"> <div class="col-3"> <p><strong>{{ order.date }}</strong></p> </div> <div class="col-3"> <p><strong>&euro;{{ order.grand_total | floatformat:2 }}</strong></p> </div> <div class="col-3"> <a href="{% url 'order_history' order.order_number %}" title="{{ order.order_number }}"> {{ order.order_number|truncatechars:8 }} </a> </div> {% for item in order.lineitems.all %} <div class="col-3"> <p><strong>{{ item.product.name }} x {{ item.quantity }}</strong></p> </div> {% endfor %} </div> {% endfor %} </div> </div> The picture contains the current output. What I am trying to achieve is a list of items under each other.
