gunicorn.service: Failed at step CHDIR spawning */fresh_env/bin/gunicorn: No such file or directory
gunicorn.service cannot open WorkingDirectory and the gunicorn executable.

How to print out data into a certain html DOM element in Django templates?
I am printing out a list of deeds in template in a todo-list app. It works fine, but I would like block <p>No deeds here yet</p> to be outside of the ul list since it doesn't need to be in a list because it's a logically separate block. Also it gets a margin that I don't want there. How to place that paragraph element outside of the ul list? {% extends "todo_lists/base.html" %} {% block content %} <h2>Deeds of a {{list_title}} list</h2> <ul> {% for deed in deeds %} <li>{{deed.title}}</li> {% empty %} <p>No deeds here yet</p> {% endfor %} </ul> {% endblock content %} -

Django and Sanity
Can Sanity be used as a database backend to Django when used in a dynamic ERP system? How would this work in practive, API calls with JSON data transfer? Would this be a good solution, or is it better to use a relational database like MySql/ Postgres/ SQLite? I am planning on making an ERP system, and have started coding in Django, and would like to know more about the dastabase connection before moving on. -

Django queryset not filtering correctly in ListView with complex lookup
I'm trying to build a Django application where I have a ListView that displays a list of objects based on complex filtering criteria, but I'm encountering issues with the queryset not filtering correctly. Here's a simplified version of my code: models.py from django.db import models class Product(models.Model): name = models.CharField(max_length=100) price = models.DecimalField(max_digits=10, decimal_places=2) category = models.CharField(max_length=100) stock_quantity = models.IntegerField() class Sale(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) quantity_sold = models.IntegerField() sale_date = models.CharField() views.py from django.views.generic import ListView from .models import Product, Sale class ProductListView(ListView): model = Product template_name = 'product_list.html' def get_queryset(self): queryset = super().get_queryset() return queryset.filter(category='Electronics', stock_quantity__gte=10, sale__sale_date__month=4) product_list.html {% extends 'base.html' %} {% block content %} <h1>Products</h1> <ul> {% for product in object_list %} <li>{{ product.name }}</li> {% endfor %} </ul> {% endblock %} I expect this ProductListView to display a list of products that belong to the 'Electronics' category, have a stock quantity of at least 10, and have had sales in the current month (April). However, when I visit the page, it displays an empty list, even though I know there are products that meet these criteria. I've tried debugging by printing the queryset in the get_queryset method, and it seems to be filtering correctly. I'm … -

How do I effectively filter locations in my database without having to loop through it manually?
In my DRF project, I have a model structured like this class ServiceLocation(models.Model): ''' Represents a location where an internet service is offered ''' SERVICE_TYPES = [ ("wifi", 'wifi'), ("fibre", "fibre"), ("p2p/ptmp", "p2p/ptmp") ] id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, null=False, blank=False) description = models.TextField() # Location address = models.CharField(max_length=150, null=False, blank=False) latitude = models.DecimalField(max_digits=18, decimal_places=15) longitude = models.DecimalField(max_digits=18, decimal_places=15) # Service service = models.CharField( max_length=10, choices=SERVICE_TYPES, null=False, blank=False) speed = models.IntegerField() def __str__(self): return f"{self.service} by {self.operator}" and I'm trying to filter this instances of this model with their relative proximity to given coordinate.

Filter deep nested related_set in Django
There are two models: class Subject(Model): categories = ManyToManyField(Category, related_name='subjects') class Category(Model): parent = ForeignKey('self', related_name='subcategories') This supposed to be translated into the following rest output: [ { ..., "categories": [ {"subcategories": [{}, {} ... {}]}, {"subcategories": [{}, {} ... {}]} ], }, { ..., "categories": [ {"subcategories": [{}, {} ... {}]}, {"subcategories": [{}, {} ... {}]} ], } ] The problem is to have set of subcategories for each category, subcategories that are in many to many relation with ancestor subject. So far I think that queryset should be something like: Subject.objects.prefetch_related( Prefetch( lookup="categories", queryset=Category.objects.filter(parent__isnull=True) .prefetch_related( Prefetch( lookup="subcategories", queryset=Subquery( Category.objects.filter( parent__pk=OuterRef("pk"), subjects__id__in=OuterRef(OuterRef("pk")), ) ) ) ) .distinct(), ), ) But this gives the error: AttributeError: 'Subquery' object has no attribute '_chain' What is wrong with the queryset. What would be the correct way of doing that? -
How to test external fetch API function with connectionerror exception Django
My code snippet fetches data from an external API. It works fine and I tested the results when I don't have any issues with the connection. However, I'm interested on testing my try except block that handles any connection problem during the function execution. I'm using python 'requests' library and I don't have any complain about it but I feel testing a connection issue will reassure my code does throw the exception. This is the closest StackOverflow answer for python only, I couldn't implement it in my code though. Also, I found another answer that suggested using Httpretty but I don't that's the approach to this question.

Django User not inheriting Group permissions

I can see the permission is set for the group but when i call get_all_permissions(), nothing shows up. That makes no sense because get_all_permissions() is suppose to return all permissions on both the User and the group. -
In django crispy form, forms.ImageField value always is None
I have a form with an image field but its value is always None.

Dark Mode doesn't sync properly?
I'm having an issue syncing the Django admin panel theme with the application's side of the theme...Whenever I switch to Light mode from Dark mode on the app side, it changes to Auto and it should rather switch to Dark mode and vice versa. The issue persists on the admin side as well for some reason. If I switch from Light mode to Dark mode whilst in the admin panel and refresh the application's side, it changes it to Light mode? It's quite odd. I tried troubleshooting it and what I could find was an error pointing at theme.js which is a file part of the admin panel. It seems the problems stems from this file... theme.js 'use strict'; { window.addEventListener('load', function(e) { function setTheme(mode) { if (mode !== "light" && mode !== "dark" && mode !== "auto") { console.error(`Got invalid theme mode: ${mode}. Resetting to auto.`); mode = "auto"; } document.documentElement.dataset.theme = mode; localStorage.setItem("theme", mode); } function cycleTheme() { const currentTheme = localStorage.getItem("theme") || "auto"; const prefersDark = window.matchMedia("(prefers-color-scheme: dark)").matches; if (prefersDark) { // Auto (dark) -> Light -> Dark if (currentTheme === "auto") { setTheme("light"); } else if (currentTheme === "light") { setTheme("dark"); } else { setTheme("auto"); } … -
Django: how to pass javascript code from python to form field attributes?
I'm using django-bootstrap-daterangepicker plugin that allows to create the following Django form: from django import forms from bootstrap_daterangepicker import fields class DateRangeForm(forms.Form): date_range = fields.DateRangeField() Everything works as expected until I want to add some dynamic daterangepicker-specific options like predefined ranges, that should be evaluated on every page refresh: $('#demo').daterangepicker({ ranges: { 'Last 7 Days': [moment().subtract(6, 'days'), moment()], 'Last 30 Days': [moment().subtract(29, 'days'), moment()], }, }) If I use: from datetime import datetime, timedelta from django import forms from bootstrap_daterangepicker import fields, widgets class DateRangeForm(forms.Form): date_range = fields.DateRangeField( widget = widgets.DateRangeWidget( picker_options = { 'ranges': { 'Last week': [ (datetime.now() - timedelta(days=7)).isoformat(), datetime.now().isoformat(), ], }, }, ), ) then dates are evaluated on server start and not re-evaluated at page refresh. Is there a way to tell Django to treat string as javascript code to pass it to rendered page as code, not as string? Or are there other ways to solve this problem?
