Wagtail one-to-one object hierarchy with enum type field
I have a wagtail site and I want to create an object hierarchy in a one-to-one matter, but with multiple options. Basically, I want that the database setup look slike this: CREATE TABLE products ( id PRIMARY KEY, product_type VARCHAR(10) CHECK (product_type IN ('BOOK', 'SHIRT', ...)), product_name VARCHAR(255), product_description TEXT, ... ); CREATE TABLE product_shirts ( id PRIMARY KEY, product_id integer REFERENCES products (id), size varchar(255), ... ); CREATE TABLE product_books ( id PRIMARY KEY, product_id integer REFERENCES products (id), author varchar(255), ... ); It is pretty straigt forward to create a regular one-to-one relationship with setting ParentalKey in the derived model. However, I want to also have an enum-type field in the parent model to check which product type we have, so that I can do something like that in my ProductsView: if object.product_type == 'SHIRT': # display additional shirt attributes elif object.product_type == 'BOOK': # display book attributes else: # unknown type, should not happen I know, that with a one-to-one relationship in wagtail I could just simply call product.shirtwhich would raise an exception, if the product is not a shirt. But it seems very cumbersome to have nested try-catch blocks if I have many different product types... … -
Azure AD Authentication with Django on AWS ALB: Redirect URI problem
I am trying to integrate Microsoft authentication with my Django app using the django_auth_adfs package. However, I encountered an error regarding a mismatch in the redirect URI. I have followed the documentation provided by django_auth_adfs for configuring Azure Active Directory integration. In my Azure portal, I registered the application and added https://myhost/oauth2/callback to the Web Redirect URLs as instructed. When attempting to authenticate, I receive the following error message with http URI instead of https: > AADSTS50011: The redirect URI 'http://myhost/oauth2/callback' specified in the request does not match the redirect URIs configured for the application '944fce1cxxxx-xxx-xxxx-4f2abba56fb6'. Make sure the redirect URI sent in the request matches one added to your application in the Azure portal. Navigate to https://aka.ms/redirectUriMismatchError to learn more about how to fix this. I have created a record for the host in route53 and configured my ALB with ACM certificate. I am using below settings file: from pathlib import Path import os BASE_DIR = Path(__file__).resolve().parent.parent SECRET_KEY = os.environ.get('DJANGO_SECRET_KEY') DEBUG = False SITE_ID = 1 ALLOWED_HOSTS = ['myhost'] CSRF_TRUSTED_ORIGINS = ['myhost'] # Application definition INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", 'django.contrib.sites', 'workspaces', 'django_auth_adfs', 'django_extensions', ] MIDDLEWARE = [ "django.middleware.security.SecurityMiddleware", "django.contrib.sessions.middleware.SessionMiddleware", "django.middleware.common.CommonMiddleware", "django.middleware.csrf.CsrfViewMiddleware", "django.contrib.auth.middleware.AuthenticationMiddleware", "django.contrib.messages.middleware.MessageMiddleware", "django.middleware.clickjacking.XFrameOptionsMiddleware", … -
Stock Quantity Not Updating on Size Selection in Django Template with JavaScript
Problem Description: I'm working on a Django project where a product can have multiple size variants, and each size has its own stock quantity. I want to display the stock information dynamically when a user selects a size using JavaScript. However, the stock information is not updating as expected. It always shows undefined in stock or Only undefined left, even though I can see the correct stock data in the browser console.

How to style a Django crispy-form label
I'm developing a small project using Django v5 and Bootstrap v5. At this stage I'm just playing around with the registration and login pages but I'd like to style the form using crispy-form and the crispy FormHelper. I can change the displayed label but (so far) I've been unable to make the label bold and/or underlined to show that it is a required field (rather than using crispy's asterisk). For what it is worth here is my forms.py file: from django import forms from django.contrib.auth import get_user_model from crispy_forms.helper import FormHelper from crispy_forms.layout import Submit, Field, Layout class LoginForm(forms.Form): username = forms.CharField(widget=forms.TextInput(attrs={'autofocus': 'autofocus'})) password = forms.CharField(widget = forms.PasswordInput) class UserRegistrationForm(forms.ModelForm): password = forms.CharField( label = 'Password', widget = forms.PasswordInput ) password2 = forms.CharField( label = 'Repeat password', widget = forms.PasswordInput ) class Meta: model = get_user_model() fields = ['username','email','first_name','last_name'] widgets = { "username": forms.TextInput(attrs={'autofocus': 'autofocus'}), } def clean_password2(self): cd = self.cleaned_data if cd['password'] != cd['password2']: raise forms.ValidationError("Passwords don't match!") return cd['password2'] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.helper = FormHelper() self.fields['username'].label= "User Name" self.fields['username'].help_text= "This will be your Login ID and must be unique" #self.helper.layout = Layout( #Field('username', label='User Name - Doug', css_class="fs-2") #) self.helper.add_input(Submit('submit', 'Register')) Note - the commented … -

Django: ORM player substitution, checking __isnull=False versus is not None
I have a Django model Player. Now this model has a save method which goes like this: def save(self, *args, **kwargs): """ Overrides the save method to convert the 'name' attribute to uppercase before saving. """ player = Player.objects.filter( Q(fide_id=self.fide_id, fide_id__isnull=False) | Q(lichess_username=self.lichess_username, lichess_username__isnull=False) | Q( name=self.name, email=self.email, email__isnull=False, name__isnull=False, ) ) if player.exists(): p = player.first() for k, v in self.__dict__.items(): if k == "_state": continue if v is None: self.__dict__[k] = p.__dict__[k] if self.check_lichess_user_exists(): self.get_lichess_user_ratings() print(f"id: {self.id}") super().save(*args, **kwargs) This is intended to look for a player which has either: The same fide_id (which should not be null, as then I would be considering two players with null values in their fide id to be the same) The same lichess_username (idem) The same combination of username and email (idem) Then, if such a player exists, then set every field of the player we're adding (if it is None) to the fields of the player already in the database. Then super().save() should overwrite the player with the same id, according to the Django docs: You may have noticed Django database objects use the same save() method for creating and changing objects.

How does one correctly define an index for efficiently querying the reverse relation for ForeignKey fields? (Django)
So I've spent days searching on and off for an answer to this question, and much to my surprise, I can't seem to find anbyone asking this specific question, nor any mentions of the confusion I have around it. My confusion lies, I suppose, in not being sure just how it is that Django builds queries under the hood, around querying a model_set reverse relation, or its related_name is specified as. It would be ideal if beginning an ORM query with parent_instance.related_name worked exactly like RelatedModel.objects does, so that, for example, the query parent_instance.related_name.filter(token__in=somelist) was able to utilize a simple field index on the "token" field created with db_index=True, just like how such an index would be able to be utilized with RelatedModel.objects.filter(token__in=somelist). However, these two queries are not equivalent; to be equivalent, the second query would have to be changed to RelatedModel.objects.filter(parent=parent_instance, token__in=somelist) (or the reverse order, RelatedModel.objects.filter(token__in=somelist, parent=parent_instance)). This leads me to believe that, in order to take advantage of indexing when querying Reverse foreignKey relations, the parent model likely n[eeds to be part of whatever indexes you plan to utilize. If one understands databases under the hood (which I do to an extent, though it is not … -
Configuring wagtail-markdown to use Prism instead of Pygments
Is there a way to inject a class into the <code> tag produced by wagtail-markdown so that I can style my Markdown code blocks with Prism instead of Pygments, which is the default syntax highlighter? Ideally, I'd like to choose the language in the first line of my Markdown as in e.g. :::python for i in range(5): print(i**2) and have it add the class="language-python" attribute required by Prism to style the block nicely. -
Accessing a foreign key's base classes's fields in UniqueConstraint

pycharm 2024.3.5 django docker compose set project path in container
I have a docker compose django project that run fine in a terminal on the server and I'm trying to setup Pycharm for development debugging. In my docker-compose .py I have a volume mapping the project root on the host file system to the container: volumes: - ../:/code So I would expect that when the project is run/debug it would build the root project directory in the container directory /code but instead it is in /opt/project directory. Docker is running on Ubuntu 24.04 on an ESXi 8 VM. How can I set the path of the project in the container to use /code and not /opt/project ? I've tried path mapping in the run/debug configurations /opt/my_app=/code setting the working directory /opt/my_app I've also spent hours looking online for any information regarding but most of what I can find is for older versions of Pycharm and is no longer valid. -

Django same slug but using different URL path
I am making a documentation site to self-host for myself; learning Django at the same time. I am at the point where I am starting to populate the website. I am wondering if there is a possibility to have two posts that have the same slug, but they are part of a different category. For example, I have two posts that are named "virus". One is under the category of "computer science" and the other is under the category of "heathcare". The website would link those pages as: .../healthcare/virus/ .../computer-science/virus/ Is there a way to use the same slug depending on the value of another field (e.g. category field) or some other technique?

How can I change device creation to be managed only through the Client model, and restrict direct device creation?
I currently have a system where devices can be created and managed through the Device model directly. However, I want to change it so that devices can only be added or deleted through the Client model, and not directly through the Device model.

Django + jQuery: "Add to Cart" Button Only Works for the First Product in a Loop

What is the best way to have row-level authorization in django with some constraints?
I have a django app which consists of multiple different models. These models are related to each others with database relations. And somehow these relations are making a hierarchy. For example: Model City can have multiple Libraries Model Library can have multiple Books Now I can't have row-level permissions over single instances without their related instaces. its like having permission to view a certain book but not the library which it belongs to. So the case is I want to have a way to define a permission over city for example to see all of its libraries (but not book). And maybe to have a permission to see all libraries and books.. etc... What I though about is to have a rule-based authroization system to handle all the cases that might a rise by following a set of rules (it is somehow a smart and persisted way to do the authorization), but I was afraid that I am overwhelming and there might be a hidden package that I can use in django which solve this case efficiently.
