Issue with Django admin form: Custom file upload field affecting unrelated form field
I'm currently working on a Django project where I've extended the admin form to allow for multiple file uploads. I am following this article. However, I'm encountering an issue where my custom file upload field seems to be affecting an unrelated form field (property_title). Specifically, after implementing the custom file upload field, the value of property_title is being changed to the name of the uploaded image. Here is simplified version of my setup: Models: from django.db import models class Property(models.Model): property_title = models.CharField(max_length=100) # Other fields class PropertyImage(models.Model): property = models.ForeignKey(Property, related_name='images', on_delete=models.CASCADE) image = models.ImageField(upload_to='property_images/') Admin.py: from django.contrib import admin from .models import Property, PropertyImage from .forms import PropertyAdminForm class PropertyImageInline(admin.TabularInline): model = PropertyImage extra = 1 @admin.register(Property) class PropertyAdmin(admin.ModelAdmin): inlines = [PropertyImageInline] Change_form.html: {% extends "admin/change_form.html" %} {% block inline_field_sets %} {% for inline_admin_formset in inline_admin_formsets %} {% include inline_admin_formset.opts.template %} {% endfor %} <fieldset class="module"> {% comment %} <label for="id_photos_multiple">Upload Multiple Photos:</label> {% endcomment %} <h2>Upload Photos</h2> <input name="photos_multiple" type="file" multiple accept="image/*" /> </fieldset> {% endblock %} How can I implement this setup so that I will be able to upload multiple images without effecting other fields of the form. This issue which I figure out is … -

(debug_toolbar.E001) The Django Debug Toolbar can't be used with tests
The complete error message is as below ?: (debug_toolbar.E001) The Django Debug Toolbar can't be used with tests HINT: Django changes the DEBUG setting to False when running tests. By default the Django Debug Toolbar is installed because DEBUG is set to True. For most cases, you need to avoid installing the toolbar when running tests.

Django failing to use its own UUID, tries to do a hex replace errors with new items added to model
This is happening on both my local and my prod solution, both are new Django projects and no data is transferred between them (new db every time). Whenever I try to make a new entry in one of my models, it throws a AttributeError 'int' object has no attribute 'replace' Initially I thought it was something wrong with my code that writes data into the db, but I found its happening when I try and enter something new via the admin panel. Tracing it back further it appears to be coming from the internal code trying to clean up the UUID but failing: hex = hex.replace('urn:', '').replace('uuid:', '') I'm pretty lost as to what to do next given this is internal Django code that's throwing a fit and I'm not giving it the UUID values, those are coming from my model which uses their recommended code: class Articles(models.Model): # Fields id = models.UUIDField(primary_key=True,default=uuid.uuid4, editable=False) title = models.CharField(max_length=256,blank=False,null=False,help_text="", verbose_name="Article Title") url = models.URLField(blank=False,null=False, help_text="", verbose_name="Article URL") image_url = models.CharField(max_length=512,blank=False,null=False,help_text="", verbose_name="Image Reference") site = models.ForeignKey(Sites, on_delete=models.CASCADE) published = models.DateField(null=True, blank=True, help_text="The date the article was published", verbose_name="Published Date") created = models.DateTimeField(auto_now_add=True,null=True, blank=True, help_text="The date the article was created in the site", verbose_name="Created … -

Broken Process Pool: Processpool executor inside django app hosted on apache
I have a django application that I would like to host on my apache server. Use case of the application is to receive requests and performs compute intensive operations over a set of given inputs. To parallelise my computations I used future.ProcessPool executor in the core of the django app. Parallelisation in indispensable for my application. While the above setup works locally, I face BrokenProcessPool error especially when the app is hosted on the apache server. Tried few tricks in some related questions (here) but I have no clear idea what is happening or how to resolve it. Could someone please help me understand: Technically, what is the underlying issue in my setup? How do I resolve it without massively changing my existing framework(Django, Apache)? Can you provide me references for an ideal workflow used in some well known data-science or graphics web applications using Django and parallel computations. This could help me revise my current framework. Below is some relevant information views.py looks like import core.ray_trace def get_heatmap(request): list_of_inputs = request.POST.get('inputs') # parallel computation of list happens inside raytrace response_data = ray_trace(list_of_inputs) return JsonResponse(response_data, status=200) Apache config for my project WSGIDaemonProcess sp python-path=/home/ubuntu/_/spaceplanning python-home=/home/ubuntu/_/venv processes=3 threads=10 request-timeout=600 WSGIProcessGroup sp … -

Getting Error: Forbidden (CSRF cookie not set.) when trying to make a post request to Django view
I am trying to create a (chrome extension + Django) password manager that will read input boxes from forms and on clicking submit it will make a POST request to the Django view with the data which will then get stored on to the postgresql database. (Keep in mind, this is only a personal project.) But on every request, I get the error: Forbidden (CSRF cookie not set.). Even though I see csrftoken cookie under the Applications tab in inspect. I am passing the csrf token along with the request so I can't figure out what the error is. I have tried getting the csrf token from cookies using Cookies.get('csrftoken') and also setting the csrf token cookie after fetching it from Django as well. This is what my view looks like in Django : @ensure_csrf_cookie def add(request): if request.method == "POST": website = request.POST['website'] username = request.POST['username'] password = request.POST['password'] user = request.user encryptedPass = cryptography.crypto(password) credentials = Credentials.objects.create(email=username, password=encryptedPass) if Website.objects.filter(user = user.id).filter(name=website).exists(): website_obj = Website.objects.filter(user = user.id).filter(name=website) # print(website_obj[0].credentials) website_obj[0].credentials.add(credentials) else: website_obj = Website.objects.create(user=user, name=website) website_obj.credentials.add(credentials) if request.headers.get('X-Requested-With') == 'XMLHttpRequest': return JsonResponse({'message':'Credentials Add'}) return redirect('add') return render(request,'add.html') This is the view where I pass the csrf token to … -

Django models - How to Aggregate Many-to-Many Related Objects into Arrays?
so I started working with Django recently, I'm having a case of many-to-many relationship between Book and Author -as simple example- a book could have multiple authors. class Book(models.Model): title = models.CharField(max_length=100) authors = models.ManyToManyField('Author', related_name='books') def __str__(self): return self.title class Author(models.Model): name = models.CharField(max_length=50) def __str__(self): return self.name My goal is to fetch the data of Book, but the problem is when a book has multiple authors, I get the same book row for each of its authors, the question is can I have a book row with all its authors stored in a list ? instead of a row for each author. Example of data fetching as JSON: [ { "id": 1, "title": "Good Omens", "authors__name": "Neil Gaiman" }, { "id": 1, "title": "Good Omens", "authors__name": "Terry Pratchett" }, { "id": 2, "title": "The Lord of the Rings", "authors__name": "J.R.R. Tolkien" } ] So I want something like this instead: { "id": 1, "title": "Good Omens", "authors__name": ["Neil Gaiman", "Terry Pratchett"] }, While it's easy to implement this via python code, I want a solution using model queries or ORM methods, to gain some performance and time since the data will be so big.

How to Properly Transform Backend Datafrom Django to Frontend Models in Angular
I am a beginner working on an Angular frontend with a Django backend. I have tried to formulate my question as precisely as possible. Please avoid downvoting; if anything is unclear, feel free to ask for clarification, and I will gladly provide more details. I have three models: Task, Subtask, and User. A Task can have multiple Subtasks. A Subtask belongs to exactly one Task. A Task can be handled by multiple Users. I receive the data tasks, subtasks, and users from the backend. A Subtask can only be created after the corresponding Task is created, as a Subtask must always have a taskId. Here are the most important data models: Backend: // Users { "id": 1, "email": "bob@bob.com", "name": "bob" } // Tasks { "id": 1, "title": "Task 1", "description": "Task 1", "due_to": "2024-06-26T13:18:08Z", "created": "2024-06-26T13:18:36.238944Z", "updated": "2024-06-26T13:18:36.239951Z", "priority": "LOW", "category": "TECHNICAL_TASK", "status": "TO_DO", "subtasks": [1], "users": [1] } // Subtasks { "id": 1, "task_id": 1, "description": "Subtask 1", "is_done": false } Frontend: In the frontend, I have a Task data structure which includes Subtasks and Users. export interface Task { id: number, title: string, description: string, dueTo: Date, created: Date, updated: Date, priority: Priority, category: Category, subtasks: Subtask[], … -

When running: py manage.py runserver I get: Unable to create process using 'c:\Users\MyUserName\Documents\GitHub\Coding Practice\Python\DjangoLearningMongo\.venv\Scripts\python.exe manage.py runserver' Another post suggested using just manage.py runserver, but that yields: Unable to create process using 'c:\Users\MyUserName\Documents\GitHub\Coding Practice\Python\DjangoLearningMongo\.venv\Scripts\python.exe "C:\Users\MyUserName\Documents\GitHub\Coding Practice\Python\DjangoLearningMongo\grocery_prices_mongo\manage.py" runserver' I have used py manage.py runserver for the entirety of the project just fine until this morning. Now, py fails to work with anything, yielding the above, and instead I must use python. These are the changes I made to the project yesterday: added static files to the project (static folder, settings.py to have STATIC_ROOT, py manage.py collectstatic, etc...) pip installed whitenoise to handle static CSS in production set DEBUG to FALSE Added 127.0.0.1 to ALLOWED_HOSTS I was still able to use py manage.py runserver (or other py manage.py commands) each step of the way as I made these changes, it was only this morning when I returned to the project that py stopped working and had to use python instead, which I had not needed to do at any point prior in the project. I even went to another project I have not run or edited in a … -
Django - Middleware losing connection with database on multi-tenant app
On my Django app I use a multi-tenant approach with isolated databases. It works well but because it relies on subdomains for each tenant, which is not scalable, I'm trying to change that. To achieve this functionality I'm trying to use middlewares and sessions to retrieve the tenant from the username and use it to set a local variable for the database routers. The logic is this: If the user is not logged, the BeforeLoginMiddleware activates and retrieves the tenant name from the user. So username@tenant1 will set tenant1 to the session. Here's the code: import threading from users.forms import LoginForm Thread_Local = threading.local() class BeforeLoginMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): if request.path == '/login/': form = LoginForm(request.POST) if form.is_valid(): complete_username = form.cleaned_data.get('username') current_db = complete_username.split('@')[1] request.session['current_db'] = current_db request.session.modified = True response = self.get_response(request) return response If the user is already logged, a second middleware will retrieve the tenant data from the session and use it to define the Thread_Local variable that is called on a function used on the database routers: class AppMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): current_db = request.session.get('current_db') setattr(Thread_Local, 'current_db', current_db) response = self.get_response(request) return response def … -
Tox+Django can't find package after Django upgrade
