I want to make a dropdown item send data to a form, help needed
I have this dropdown that fills itself with the make of cars inside my database and i want to make each one of the items(when selected) send their name to a dorm (ex: if i press Fiat i want the item to send the name Fiat to the form). I would appreciate any help :) Also if you saw a post with a similar question let me know, thanks :) Here is the code i got: {% extends "layout.html" %} {% block content %} {% load static %} <link rel="stylesheet" href="{% static 'css/styles.css' %}?v=1"> <!-- search bar for advanced search--> <div class="container-search"> <br> <h1 class="text-center text-white">Search Cars</h1> <hr> <form method="get" action="{% url 'search' %}"> <!-- Dropdowns - Side by side --> <div class="d-flex justify-content-center mb-3"> <div class="dropdown me-3"> <button class="btn btn-danger dropdown-toggle" type="button" id="makeDropdown" data-bs-toggle="dropdown" aria-expanded="false"> Select Make </button> <ul class="dropdown-menu" aria-labelledby="makeDropdown"> {% for make in car_makes %} <post value="{{make.make}}" name="{{ make.make }}" class="text-dark">{{ make.make }}</post> <br> {% endfor %} </ul> </div> <div class="dropdown"> <button class="btn btn-danger dropdown-toggle" type="button" id="modelDropdown" data-bs-toggle="dropdown" aria-expanded="false"> Select Model </button> <ul class="dropdown-menu" aria-labelledby="modelDropdown"> {% if cars != None %} {% for car in cars %} <option value="{{ car.model }}" class="text-dark">{{ car.model }}</option> {% endfor %} … -
Custom generic istruthy/isfalsy lookup doesn't work on Foreign Keys
In my Django project, I'm in need of a generic istruthy/isfalsy lookup that would work on any type of database field. Example of models.py: class MyModel(models.Model): my_charfield = models.CharField(...) my_decimalfield = models.DecimalField(...) my_datefield = models.DateField(...) my_boolfield = models.BooleanField(...) my_fkfield = models.ForeignKey(...) What I want to be able to do: MyModel.objects.filter(my_charfield__isfalsy=True) MyModel.objects.filter(my_decimalfield__isfalsy=True) MyModel.objects.filter(my_datefield__isfalsy=True) MyModel.objects.filter(my_boolfield__isfalsy=True) MyModel.objects.filter(my_fkfield__isfalsy=True) I have defined two custom lookups to do that: from django.db.models import Lookup, BooleanField, ForeignKey, Field class IsTruthy(Lookup): lookup_name = 'istruthy' def as_sql(self, compiler, connection): lhs, params = self.process_lhs(compiler, connection) if isinstance(self.lhs.output_field, BooleanField): return f"{lhs} = TRUE", params if isinstance(self.lhs.output_field, ForeignKey): lhs = f"{lhs}_id" return f"{lhs} IS NOT NULL", params return f"{lhs} IS NOT NULL AND {lhs} <> ''", params class IsFalsy(Lookup): lookup_name = 'isfalsy' def as_sql(self, compiler, connection): lhs, params = self.process_lhs(compiler, connection) if isinstance(self.lhs.output_field, BooleanField): return f"{lhs} = FALSE", params if isinstance(self.lhs.output_field, ForeignKey): lhs = f"{lhs}_id" return f"{lhs} IS NULL", params return f"{lhs} IS NULL OR {lhs} = ''", params Field.register_lookup(IsTruthy) Field.register_lookup(IsFalsy) These custom lookups work on all fields except ForeignKey. When used on a ForeignKey, the following error is triggered: django.core.exceptions.FieldError: Unsupported lookup 'isfalsy' for ForeignKey or join on the field not permitted I have tried different variations of this code to handle … -
Temporarily load a fixture for development
I would like to create a lot of dummy products for use in development. The dummy products need to be in the development database, in addition to a copy of all of the data that the production database has, so that I can see what the dummy products will look like in the website. How can I do this easily? I've looked into fixtures, but I can't figure out how to "apply" a fixture on top of a copy of the production database, and how I might be able to unapply it when I'm done with that part of development. -
Is this djoser implementation secure?
This question may be too broad for StackOverflow, but I'm not sure where else to go for help. I wrote a simple authentication system in Django with Djoser and its JWT implementation, using jQuery on the frontend. I really don't know what I'm doing though, and I'm about 99% sure I did it wrong and it's totally insecure. First, when a user submits the login form, I send a POST request to retrieve a refresh token and an access token. The refresh token is stored as a cookie, and the access token is stored in sessionStorage: // Post the form $.post("/auth/jwt/create/", $(this).serialize()) // Success: store tokens & redirect .done(function(data) { // Logged in: set redirect path & store tokens if (data.refresh !== "undefined" && data.access !== "undefined") { Cookies.set("refresh_token", data.refresh, { expires: 30, secure: true, sameSite: "strict" }); sessionStorage.setItem("access_token", data.access); } }) I have another simple script that runs every time a page is loaded. There, I verify the access token, attempt a refresh if it's invalid, fetch user data using the access token, then post that user data to the backend to login. This script also logs the user out if on the logout page: // Log in or … -
Data not saved to database
I don't know what's going on here, whenever I try to create a buzz with the status set to Draft (this is also the default status set on the model) Django returns a 302 response and does not saved it to the database. However, when I change the status to Published it just saves it normally on the database. Here's the code to the view def buzz_create(request): form = BuzzCreateForm() if request.method == 'POST': form = BuzzCreateForm(data=request.POST) if form.is_valid: buzz = form.save(commit=False) buzz.author = request.user buzz.save() return redirect(to=reverse('buzz:buzz_list')) return render( request=request, template_name='buzz/create.html', context={ 'form': form } ) Here's the code to the model: class BuzzPublishedManager(models.Manager): def get_queryset(self): return ( super().get_queryset().filter(status=Buzz.Status.PUBLISHED) ) class Buzz(models.Model): class Status(models.TextChoices): PUBLISHED = 'PBL', 'Published' DRAFT = 'DFT', 'Draft' title = models.CharField(max_length=250) body = models.TextField() slug = models.SlugField(max_length=250, unique_for_date='publish') publish = models.DateTimeField(default=timezone.now) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) author = models.ForeignKey( to=settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='buzzes' ) status = models.CharField( max_length=3, choices=Status, default=Status.DRAFT ) published = BuzzPublishedManager() objects = models.Manager() class Meta: verbose_name_plural = 'Buzzes' ordering = ['-publish'] indexes = [ models.Index(fields=['-publish']) ] def __str__(self): return self.title The objects in the model was not there before.

Django Allauth's Google Login Redirect and Page Design
Currently, on the login page, I have a button: <div class="d-grid gap-2"> <a href="{% provider_login_url 'google' %}" class="btn btn-danger"> <i class="fab fa-google"></i> Sign in with Google </a> </div> This redirects to accounts/google/login/, and that page allows for redirection to Google authentication. I have two problems: I don't know if these two steps are necessary and I don't see the value of having the extra step accounts/google/login/. I don't know how to replace the standard layout of the accounts/google/login/ page (in case it is really needed). -
Access request session data of DetailView in CreateView in django
I am writing a library management system in Django. There are two views that I am having a bit of a struggle. The BookDetailsView lists the details of a Book such as title, price, etc. class BookDetailsView(LoginRequiredMixin, DetailView): model = Book template_name = 'book_detail.html' def get(self, request, *args, **kwargs): response = super().get(request, *args, **kwargs) request.session['book_pk'] = kwargs['pk'] return response # used to mark book as read or unread def post(self, request, *args, **kwargs): if 'is_read' in request.POST: book = Book.objects.get(pk=kwargs['pk']) book.is_read = True book.save() return HttpResponseRedirect(self.request.path_info) In the BookBorrowView, I display a form where the reader can borrow a book. Two fields are preset (borrowers and book), and I don't want the user to be able to change them. At the moment, the user can select among many options. class BookBorrowView(LoginRequiredMixin, CreateView): model = BookBorrowTransaction template_name = 'book_borrow.html' fields = ['book', 'borrowers', 'date_borrowed', 'to_return', ] success_url = reverse_lazy('home') def get_initial(self): initial = super(BookBorrowView, self).get_initial() initial['borrowers'] = get_object_or_404(CustomUser, email=self.request.user.email) initial['book'] = get_object_or_404(Book, title=Book.objects.get(pk=self.request.session['book_pk']).title) # need the book id here print(self.request.GET) print(self.request.POST) print(self.request.session['book_pk']) return initial The following is a screenshot of the form displayed by the BookBorrowView. I have two questions: I am passing the primary key for the book through request.session … -

SAP Connection failed: name 'Connection' is not defined, PYRFC in django
I'm experiencing an issue with the pyrfc library in my Django project running on Pythonanywhere server. Specifically, I am trying to use the Connection class from pyrfc to establish a connection to an SAP system, but I am encountering an ImportError when I try to import Connection in my views.py file. The error message says: SAP Connection failed: name 'Connection' is not defined However, when I test the same code in the Django shell, everything works fine, and the Connection class is correctly imported. I have verified that the environment variables SAP_NWRFC_HOME and LD_LIBRARY_PATH are set correctly, and the libsapnwrfc.so library loads successfully. If i do make import like from pyrfc import Connection then it gives the error 2025-01-22 07:28:52,598: Error running WSGI application 2025-01-22 07:28:52,599: ImportError: cannot import name 'Connection' from 'pyrfc' (/home/moeez007/.local/lib/python3.10/site-packages/pyrfc/__init__.py) 2025-01-22 07:28:52,599: File "/var/www/moeez007_pythonanywhere_com_wsgi.py", line 80, in <module> 2025-01-22 07:28:52,600: from pyrfc import Connection i also have tried to set the environment variables in the wsgi file import os os.environ["SAP_NWRFC_HOME"] = "/home/moeez007/nwrfcsdk" os.environ["LD_LIBRARY_PATH"] = "/home/moeez007/nwrfcsdk/lib" but still the same, i also have tried to run this as a separate file but still the same why is it working in the django shell and python but not … -
How to configure Nginx to serve Django and a Wordpress site on a specific route?
Good day good people of SO! I have a Django app on a Hetzner server and a Wordpress site on a Hostinger server. I want to configure Nginx on my Hetzner server to serve the Django app and when it requests the /route-name route, it serves a Wordpress site from the Hostinger server. I've already allowed the IP address of my Hetzner server to access the Wordpress site. Hetzner server is running Nginx and Hostinger is running Apache2 if that's relevant. I know there are quite a few questions and answers regarding configuring Nginx to serve Django and Wordpress but I've been scouring this forum and the Internet for several hours now with no solution found for my problem. I suspect it may have to do with my Nginx config, but after trying out several configurations accepted on here and elsewhere, I can't seem to make it work. This is what I currently have for my Nginx config: server { location = /favicon.ico { access_log off; log_not_found off; } location /static/ { alias /var/www/example.com/static/; } location /media/ { alias /var/www/example.com/media/; } # Reverse proxy for /freebies location /route-name/ { proxy_pass http://<IP-ADDRESS OF HOSTINGER SERVER>/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; … -

How to create a Django custom field with different representations in admin, database, and Python code?
I want to create a custom model field in Django that can store values in bytes in the database but allows users to interact with it in gigabytes (GB) in the Django admin interface. The goal is for the field to handle all necessary conversions seamlessly. Specifically, the field should accept input in GB when adding or editing a record in the admin, convert it to bytes before saving it to the database, and then retrieve it in bytes for use in Python code. I’ve started working on this by overriding methods like to_python, get_prep_value, from_db_value, and formfield, but I’m not entirely sure how to structure these methods to ensure the field behaves as intended. Here is what I already have: class GigabyteField(models.BigIntegerField): def to_python(self, value): if value is None: return value try: return int(value) except (TypeError, ValueError): raise ValueError(f"Invalid value for GigabyteField: {value}") def get_prep_value(self, value): if value is None: return None return int(value * (1024**3)) def from_db_value(self, value, *args): if value is None: return value return int(value / (1024**3)) -
linux ssh key is available to wsl2 django launched by Windows PyCharm
I am working in a development environment for my Django application where I have PyCharm installed on windows, and I launch django in wsl2. This has been working for me flawlessly for a while now. However just now I have a new need to have an ssh key for 3rd party command line tool my application invokes. I created the key in linux and I can execute the command successfully in a linux terminal, however when my django application runs the command fails with the same error it failed with prior to creating my ssh key. At one point I was 100% confident I had found a workaround of starting ssh-agent and then adding an environment variable to my run configuration to set SSH_AUTH_SOCK to the value of SSH_AUTH_SOCK from my terminal, however over the course of trying to find an actual acceptable solution, I can no longer reproduce this, so I'm unsure if that ever even worked or it worked for another reason that I was not aware of. I can confirm that in this scenario my SSH_AUTH_SOCK does have the correct value in django. Every time the command requiring the ssh key is executed I get an error … -

I got 'IncompleteSignature' issue in Aliexpress open platform
I am working over Django using python. I am working on the official SDK for python of Aliexpress. I am trying to get the ACCESS TOKEN from Aliexpress. I got 'IncompleteSignature' issue which means 'The request signature does not conform to platform standards as the part of the response body. Here is full results : {'error_response': {'type': 'ISV', 'code': 'IncompleteSignature', 'msg': 'The request signature does not conform to platform standards', 'request_id': '2141154c17373626146733360'}} My code is very simple because I referred the sample code of their site.

I was shocked. It was not even python. And this advice can be only implemented if I modified their SDK itself. I am not sure if the python SDK is of practical working quality.

How to Include a Message Field in Structlog Logs and Best Practices for ElasticSearch Integration
I'm working on a Django project where logging is critical, and I'm using structlog to format and manage logs. The plan is to send these logs to ElasticSearch. However, I've encountered an issue: the logs are missing the "message" field, even though I explicitly pass a message in the logger call. Here’s the log output I currently get: { "code": 200, "request": "POST /api/push-notifications/subscribe/", "event": "request_finished", "ip": "127.0.0.1", "request_id": "d0edd77d-d68b-49d8-9d0d-87ee6ff723bf", "user_id": "98c78a2d-57f1-4caa-8b2a-8f5c4e295f95", "timestamp": "2025-01-21T10:40:43.233334Z", "logger": "django_structlog.middlewares.request", "level": "info" } What I want is to include the "message" field, for example: { "code": 200, "request": "POST /api/push-notifications/subscribe/", "event": "request_finished", "ip": "127.0.0.1", "request_id": "d0edd77d-d68b-49d8-9d0d-87ee6ff723bf", "user_id": "98c78a2d-57f1-4caa-8b2a-8f5c4e295f95", "timestamp": "2025-01-21T10:40:43.233334Z", "logger": "django_structlog.middlewares.request", "level": "info", "message": "push notification subscribed successfully" } Here’s my current setup: settings.py Logger Configuration LOGGING = { 'version': 1, 'disable_existing_loggers': False, "formatters": { "json_formatter": { "()": structlog.stdlib.ProcessorFormatter, "processor": structlog.processors.JSONRenderer(), }, "plain_console": { "()": structlog.stdlib.ProcessorFormatter, "processor": structlog.dev.ConsoleRenderer(), }, "key_value": { "()": structlog.stdlib.ProcessorFormatter, "processor": structlog.processors.KeyValueRenderer(key_order=['timestamp', 'level', 'event', 'message']), }, }, 'handlers': { "console": { "class": "logging.StreamHandler", "formatter": "plain_console", }, "json_file": { "level": "INFO", "class": "logging.handlers.RotatingFileHandler", "filename": "logs/ft_json.log", "formatter": "json_formatter", "maxBytes": 1024 * 1024 * 5, "backupCount": 3, }, "flat_line_file": { "level": "INFO", "class": "logging.handlers.RotatingFileHandler", "filename": "logs/flat_line.log", "formatter": "key_value", "maxBytes": 1024 * 1024 * … -

Override existing custom Django App template tags
I have an application that uses Weblate to manage translations. I use weblate/weblate Docker image, with my own customizations built as a separate Python package extending this image and built on top of it. The problem is that in the Weblate HTML templates there is an icon template tag that is supposed to load SVG icons from a STATIC_ROOT or a CACHE_DIR location - but my application runs in a serverless setup and as such offloads all of the static resources to a S3 bucket. For most of the resources it works fine, but due to that template tag logic the icons are not loaded and I get these error messages - weblate-1 | gunicorn stderr | [2025-01-21 12:41:08,913: WARNING/1540] Could not load icon: FileNotFoundError: [Errno 2] No such file or directory: '/app/cache/static/icons/weblate.svg' weblate-1 | gunicorn stderr | [2025-01-21 12:41:08,918: WARNING/1540] Could not load icon: FileNotFoundError: [Errno 2] No such file or directory: '/app/cache/static/icons/wrench.svg' weblate-1 | gunicorn stderr | [2025-01-21 12:41:08,919: WARNING/1540] Could not load icon: FileNotFoundError: [Errno 2] No such file or directory: '/app/cache/static/icons/plus.svg' weblate-1 | gunicorn stderr | [2025-01-21 12:41:08,923: WARNING/1540] Could not load icon: FileNotFoundError: [Errno 2] No such file or directory: '/app/cache/static/icons/dots.svg' I wrote my custom … -

How to Set Up Google Cloud ADC (Application Default Credentials) in Django on PythonAnywhere?
I'm trying to set up Google Cloud's Application Default Credentials (ADC) for my Django project on PythonAnywhere, but I keep encountering the following error: Error creating story: Your default credentials were not found. To set up Application Default Credentials, see https://cloud.google.com/docs/authentication/external/set-up-adc for more information. What I've Tried: Created a Service Account: Created a service account in Google Cloud and downloaded the JSON key file. Stored the file at: /home/footageflow/helloworld2003-754c20cfa98d.json. Set the GOOGLE_APPLICATION_CREDENTIALS Environment Variable: Added the following to .bashrc export GOOGLE_APPLICATION_CREDENTIALS="/home/footageflow/helloworld2003-754c20cfa98d.json" Tried Programmatic Credentials: Explicitly set the variable in my Django code import os os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "/home/footageflow/helloworld2003-754c20cfa98d.json" Attempted CLI Authentication: Installed the gcloud CLI on PythonAnywhere. Ran gcloud auth application-default login and authenticated successfully. enter code here Problem: Despite trying all these steps, the error persists when I run the code on PythonAnywhere. The same code works fine locally after authenticating with gcloud. My Questions: Is there something specific I need to configure for ADC to work on PythonAnywhere? Do I need to grant additional permissions to my service account in Google Cloud? Could the issue be related to how PythonAnywhere handles environment variables or service accounts? Additional Information: The Django project is running on PythonAnywhere. Locally, the project works … -
Django ORM filter on datetime understands entries with a 'Z' offset, but not '+0000' offset
I have a MySQL database that mirrors a salesforce database. My table has a column for "createddate" that is contains ISO-8601 datetime entries. Some of the entries have an offset of "Z" and some of the entries have an offset of "+0000" like this: 2025-01-20T17:18:18.000Z 2025-01-20T18:11:10.000Z 2025-01-20T17:27:55.000+0000 2025-01-20T17:29:46.000Z 2025-01-20T17:28:19.000+0000 When I attempt to filter on a certain date, the filter ONLY returns lines that have a "Z" offset. lines with "+0000" are not returned. My filter code looks like: receipts = Receipt.objects.filter(createddate__date='2025-01-20').count() As far as I can tell, both formats conform to ISO-8601. I do have USE_TZ set to true in my settings.py the field is configured in models.py like: createddate = models.CharField(db_column='CreatedDate', max_length=28, blank=True, null=True) Relatively new to django and its ORM, I'm currently working around with a raw SQL query but I'd rather do it natively if possible. -
Duplicate the content of the block in Django template
Suppose I have the following code in base.html: <meta name="description" content="{% block description %}Some description{% endblock %}"> Other templates that extend base.html, override the contents of the block and so each page gets its own description. What if I want to add <meta property="og:description" content="" />, where the value of the content should equal the above value? How can I add the contents of the block into another place? -
Javascript display raw JSON instead of rendering the HTML content like the "index" button
I'm developing a Django web application that allows users to follow each other and view a feed of posts from the users they follow. I have a button that triggers an AJAX request to a Django view designed to fetch and render the relevant posts. My Django view correctly retrieves the posts from users the currently logged-in user follows and returns them as a JSON response. However, when my JavaScript code receives this response, it doesn't render the posts into the page as HTML. Instead, the browser displays the raw JSON data. I expect the JavaScript to use the JSON data to update the page with rendered HTML content representing the posts, but this isn't happening. How can I ensure that my JavaScript correctly processes the JSON and renders the posts as HTML? thanks for helping ❤️ post.js: document.addEventListener('DOMContentLoaded', function() { // Use buttons to toggle between views const index = document.querySelector('#index') const following = document.querySelector('#following') if(index) { index.addEventListener('click', () => load_data('index')); } if (following) { following.addEventListener('click', () => load_data("following")); } // By default, load the index load_data('index'); }); function load_data(type) { console.log("type:", type); let url; if (type == "index") { url = "/post" } else if (type == "following") …
