I try to use django-filters in my Django app. I am using it with pagination. Page renders properly (it just works), but without filter fields that I created. Only submit button shows.

new Media files in django gets 404 not found nginx
My old media files (photos) are loading correctly but when new medias are uploaded I'm getting 404 not found by nginx. I used docker and this is my volume part of docker compose: volumes: - '/root/docker-compose/data/media/MEDIA/:/app/MEDIA' all media files are loading correctly and saved correctly but when new files added I get 404 not found. although all files are uploaded correctly and I can see them not only in docker container but also outside of it. but still getting 404 not found! I tried changing media files and reseting all docker compose details and uwsgi configs. but still not fixed. and also try refactor settings and urls. -

How long does it take to install chromadb on Ubuntu?
I have developed a django project and am trying to deploy to AWS EC2 Instance. My project uses chromadb so I try to install with this command. pip install chromadb Then it installs all the related dependencies but when it starts to install hnswlib, it freezes. Building wheels for collected packages: hnswlib Building wheel for hnswlib (pyproject.toml) ... \ It doesn't give any error but no progress. How to handle this? Should I wait? This was the second time for me to deploy this kind of project but at the first time, I installed chromadb without any issue. But at that time, I used the Instance that my client has provided. Now I created the Instance with myself. Are there any kind of settings about Instance? Thanks -
Django BaseFormSet and formset_factory not working properly
I took reference from https://whoisnicoleharris.com/2015/01/06/implementing-django-formsets.html to create a formset that creates multiple users from a model named Office365User that has a foreign key field linked to another model named Domain, but the formset is not saving the form.

Integrating Veracode logging formatter library into Django project
there! I'm currently working on resolving a vulnerability issue reported by Veracode, specifically CWE 117 (Improper Output Neutralization for Logs). To address this issue, I need to implement the Veracode logging formatter library available at logging-formatter-anticrlf in my Django project. In Django, there is a configuration file called settings.py where the logging behavior for the application is defined using formatters, handlers, and loggers. Here's an example of the configuration: # Logging LOGGING = { 'version': 1, 'formatters': { 'verbose': { 'format': '{levelname} {asctime} {filename}:{lineno} {message}', 'style': '{', }, 'simple': { 'format': '{levelname} {message}', 'style': '{', }, }, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'formatter': 'verbose', }, 'file': { 'level': 'DEBUG', 'class': 'concurrent_log_handler.ConcurrentRotatingFileHandler', 'filename': os.path.join(BASE_DIR, '..', '..', 'log-debug.log'), 'maxBytes': 1024 * 1024 * 1024, 'backupCount': 365 * 7, 'formatter': 'verbose', }, }, 'root': { 'handlers': ['console', 'file', 'errorfile'], 'level': 'DEBUG', }, 'loggers': { 'root': { 'handlers': ['console', 'file', 'errorfile'], 'propagate': True, 'level': 'DEBUG', }, 'django.request': { 'handlers': ['console', 'file', 'errorfile'], 'propagate': False, 'level': 'DEBUG', }, 'django.server': { 'handlers': ['console', 'errorfile'], 'propagate': False, 'level': 'DEBUG', }, 'webportal': { 'handlers': ['console', 'file', 'errorfile'], 'propagate': False, 'level': 'DEBUG', }, } } In each module of the Django application, the LOGGER is instantiated … -
Reduce database hit when using django-taggit and mymodel.tags.all in a template
I'm using django-taggit in Django 3.2 and can't figure out how to prevent it from hitting the database for every object in a list view template. Here's how I'm using it: class Quest(TagsModelMixin, models.Manager): # etc. In a ListView html template, I am displaying all Quest objects and their tags like this: {% for obj in quest_queryset %} {{obj.name}}: {{ obj.tags.all }} {% endfor %} At first, this was hitting the DB twice per object. I found that if I prefetch_related I could remove half of them: quest_queryset = quest_queryset.prefetch_related('tags') But I'm still getting one hit per object. How can I eliminate this repetition? Here's the offending query as shown by django-debug-toolbar, when there are 5 Quest objects. -
Django: How to format nested data, including a list of dictionaries, as multipart/form-data for posting?
How can I format nested data, including a list of dictionaries, as multipart/form-data for posting in Django? DATA = { "title": "Test Entry", "subcategory_id": subcategory.pk, "description": "Description for test entry.\n" * 2, "price": 150_000.00, "publisher": publisher.pk, "location": { "town": "Ant Town", "landmark": "Pink Poolside", }, "cover": _simple_image(), "images": [_simple_image(), _simple_image()], "specs": [ {"name": spec_field1.name, "value": "1000", "field_id": spec_field1.id}, {"name": spec_field2.name, "value": "SSD", "field_id": spec_field2.id}, ], "tags_ids": [tag.id for tag in TagFactory.create_batch(2)], } def test_something_doesnt_go_wrong(self): self.client.force_authenticate(user=UserFactory()) url = reverse("entries:entry-list") response = self.client.post(url, data, format="multipart") self.assertEqual(response.status_code, 201) self.assertEqual(len(response.data["images"]), 2) self.assertEqual(len(response.data["tags"]), 2) This is the error I get when I run my test suite. AssertionError: Test data contained a dictionary value for key 'location', but multipart uploads do not support nested data. You may want to consider using format='json' in this test case. Is this even legal? Is the API badly designed (I'm wondering). What can I do here? I can't seem to wrap my head around how to achieve this using QueryDict. -
Figma to Django (Python Web Framework) [closed]
Haii! I am new to Python web development, and I am using Python to master it further. I am trying to create a website using Django, and I already have my design in Figma. I am proficient in creating attractive user interfaces in Figma, but I have never used it with Python / exported. I do not know how to easily export Figma to Django. Does anyone know how to import Figma to Django without exporting every single item into an HTML file? Is that the only solution? Or am I doing something wrong? and are there any youtube / sites / plugin that you can recommend for me that I can try? I'm honestly lost for how to make exporting Figma to Django easier for myself. If there's no better solution, I completely understand, but I wanted to see if there was a better way than converting everything myself, which would take a significant amount of time. Thank you so much!! -

Is there a way to configure Django JWT authorisation/confirmation emails without SMTP server?
We are building an app with Django using Djoser and want it to send authorisation/confirmation emails to users. But the client said that there is no SMTP server on the domain he provides. So, is there some third-party api service that can send emails for our app?

Install requirements from Django project with VS Code
I try to run and open the development server of a Django project in VS Code, that I created with GidPod IDE. When I open the project in GidPod (where I created it), install the requirements, create an env.py, set the 'SECRET_KEY' variable and I can start the server with python3 manage.py runserver. Then I open the exact same project in VS code, I create a virtual environment and install the requirements from requirements.txt as I did in GidPod with pip3 install -r requirements.txt.

Django custom widget: best approach
Django: custom widget I use a material-kit library for django which offers a design for rendering form fields except for selects which is only available in the PRO version. I coded a custom selectpicker widget which renders similar to the selectpicker of the PRO version of material-kit. In a form, I have a lot of "select" fields to render with my selectpicker widget. To limit the repetition of the code I defined a template select_field.html which displays the selectpicker.html of my widget when I insert a field having this widget in my final template using an include. Isn't there a more efficient and/or elegant way to achieve the same result? #model.py dem_sex = models.IntegerField('Sexe', null=True, blank=True) #forms.py dem_sex = forms.TypedChoiceField(widget=Selectpicker(label='Sexe - SELECTPICKER',attrs={'class': ''}),choices=SEX_CHOICES, empty_value=None,required=False) #widget.py from django.forms.widgets import TextInput class Selectpicker(TextInput): template_name = 'widgets/selectpicker.html' def __init__(self, label=None, choices=None, *args, **kwargs): self.choices = choices self.label = label super().__init__(*args, **kwargs) def get_context(self, name, value, attrs=None): context = super().get_context(name, value, attrs) if self.choices: context['choices'] = self.choices if self.label: context['label'] = self.label return context #selectpicker.html {% with css_classes=widget.attrs.class|default:'' %} <div class="row ms-3 me-3"> <div class="col-md-12 selectpicker-div"> <div class="selectpicker"> <div class="label floating-label">{{label}}</div> <input class="textBox hidden" type="{{ widget.type }}" name="{{ widget.name }}"{% if widget.value is None … -

{% block content %} {% endblock %} displayed as text
I'm going through an online tutorial on python web development: https://www.youtube.com/watch?v=dam0GPOAvVI&list=PL7AeU6Jfo1ue-VZ6SI9x0EOCW2hhGC1l6&index=4&t=2214s However, despite double check all the codes are the same, I can't get visual studio to recognize the {% block content %} {% endblock %} part of the code. The expected output should be only the contents between {% block content %} {% endblock %}, which is none in this case. However, '{% block content %} {% endblock %}' is displayed as text on the web page, which it should not be. And the rest of the codes on other templates did not work as well. It seems that visual studio code does not recognize this syntax, maybe I need to configure some setting for it to work but I can't find it, any help is much appreciated. <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous" /> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" crossorigin="anonymous" /> <title> {% block title %}Home{% endblock %} </title> </head> <body> <nav class="navbar navbar-expand-lg navbar-dark bg-dark"> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbar"> <span class="navbar-toggler-icon"></span> </button> <div class = "collapse navbar-collapse" id="navbar"> <a class="nav-item nav-link" id="login" href="/login">Login</a> <a class="nav-item nav-link" id="SignUp" href="/sign_up">Sign Up</a> <a class="nav-item nav-link" id="logout" href="/logout">Log Out</a> <a class="nav-item … -
