How to handle django.db.utils.IntegrityError for asynchronous POSTs? (Can you except an IntegrityError?)
I have a model with a @BEFORE_CREATE signal hook like thus: from django.lifecycle.hooks import BEFORE_CREATE class Item(models.Model): title = models.CharField() slug = models.JSONField(unique=True) @hook(BEFORE_CREATE) def populate_slug(self): # Create a slug from the title # If the slug already exists, append "-{n}" # to make sure it is unique slug[0] = slugify(self.title) n = 2 while List.objects.filter(slug=slug).exists(): slug[0] = f"{slug[0]-{n}" n += 1 self.slug = slug This works fine in my tests when the Items are created synchronously one-after-another: i1 = Item.objects.create(title="Hello") i2 = Item.objects.create(title="Hello") self.assertEqual(i1.slug, ["hello"]) self.assertEqual(i2.slug, ["hello-2"]) However, on my actual frontend, I'm creating these objects asynchronously and at the same time: const item1 = axios.post(POST_ITEMS_URL, {title: "Hello"}) const item2 = axios.post(POST_ITEMS_URL, {title: "Hello"}) Promise.all([item1, item2]); Which gives me this error: web_1 | django.db.utils.IntegrityError: duplicate key value violates unique constraint "app_item_slug_key" web_1 | DETAIL: Key (slug)=(["hello"]) already exists. An easy fix (I think) would be to change my @hook to be AFTER_CREATE but I would like to avoid the additional write on all objects if possible. Is it possible to put an except IntegrityError somewhere? If so, where? Or how else can I overcome this problem? I'm using PostGRE if that matters. -

Django ownership assignment to modify or delete entries
First post here. I followed the project code in the Python Crash Course book, so if the code looks similiar that is why. In my django project, I want all the users to be able to view everything on the website. However, I want to have only the users who entered information in the entries to be able to edit and delete said entries. I know I need to assign ownership, but I'm having difficulty assigning it. currently I have a default setting enabled. For some reason if I take out the default it messes everything up. urls.py """Defines URL patterns for research_topic_database.""" # research_topic_database from django.urls import path from . import views app_name = 'research_topic_database' urlpatterns = [ # Home page path('', views.index, name='index'), # Page that shows all the research category topics. path('topics/', views.topics, name='topics'), # Detail page for a single research entry submission. path('topics/<int:topic_id>/', views.topic, name='topic'), # Page for adding a new research entry submission. path('new_entry/<int:topic_id>/', views.new_entry, name='new_entry'), # Page for editing an entry. path('edit_entry/<int:entry_id>/', views.edit_entry, name='edit_entry'), ] models.py class Topic(models.Model): """A research category for topic submissions to fall under.""" category = models.CharField(max_length=19, choices=CATEGORY_CHOICES, blank=True) date_added = models.DateTimeField(auto_now_add=True) def __str__(self): """Return a string representation of the model.""" … -

Django and HTML Dropdown : Populate Parent / Child field with Selected any one of the Child Attributes
I have 3 models which are being used for Dropdown, and user can select value from any of dropdown. When user select the parent the child dropdown auto-filters (this is working), however need a functionality where, when a user select a child, parent dropdown will also get filter. While doing research I came across with such functionality on site "https://www.hertzcarsales.com/nashville.htm?utm_source=google&utm_medium=organic&utm_campaign=GoogleLocalListing". Due to security reason cannot share actual models. however can refer to the site. User can select Vehicle Make, and the model + Body Style will auto filter, and when user selects just Body Style, then Make & Model will be filtered accordingly. For example, in below screenshot I just selected Body Style as Truck, and all Make & Model are auto-filtered. Please suggest or point me how this can be doable, just a pointer or small suggestion would help. I did tried using JavaScript, but unable to do reverse dropdown filter. -

How to use a request.session stored value within a DetailView as the initial data to a ModelForm input field?
I'm a beginner at Django and I'm currently developing my first project. I'm using DetailView to display information from an object and in this same template there's a button that redirects to a ModelForm template. I've already gotten how to prepopulate the user field with form.save(commit=False) and a date field by simply setting a default on models. But I'm having trouble setting a ForeignKey field up. I've already tried different methods and variations of them but none worked. The one below is the last one I've tried. I've already studied and tried to make it work but I'm not sure how to use django sessions to pass the '''Book.id''' or anything that could possibly replace it from the DetailView to the ModelForm field. There were times I've gotten an error saying certain object was not JSON serializable then I've tried to make it work importing serializing modules and it didn't work as well. I also have doubts if I'm using the best method to achieve what I want using the DetailView class. Obs.: the input field is there with the options to pick. My intention is to set the initial value with previous page object. views.py class BookView(DetailView): model = … -

Django + Vue deployment pythonanywhere.com
I am new to vue and cannot figure out how to get my Django/Vue app deployed on pythonanywhere.com. For the backend I am using cookiecutter which I have deployed as normal using [this guide][1] . This is working and I can view the API endpoints. I have been having difficulty connecting up the vue part, this is probably due to being new to JS frameworks so I am not entirely sure how they run in production. From [this post][2] I know I need to serve my Vue files as static files but I dont know how to do this. I have tried to build my vue project on my local machine which creates a dist folder, I added the contents of this folder to my django static folder and ran collectstatic command but this has not worked for me. Does anyone have experience with Vue and Django on pythonanywhere that could point me in the right direction? Any ideas of how to get this working? Thanks, John -
(Bad Gateway) ERROR 502 Nginx, Gunicorn, Django DRF, Vue.js
I have deployed ecommerce made with Django and Vue.js on a VPS. Everything is working fine, but when I try to use POST method, Error 502 appears in console and nothing happens. The API is able to show products from Django Admin, but I can't post anything from the frontend. It always gives me this Error 502 problem. I have been trying to solve this for a few day already and still don't get what is wrong. Hope you can help.

Is it good practice to use HTML forms to display data?
I am planning on using the form-control classes from Bootstrap to display data. I have an inclusion template tag that generates a "form" from objects in the DB. Is this a good practice? Or should I be investing my time in searching for a better way to display data?
