the server does not distribute django + gunicorn + nginx static
On my ubuntu 20.04 I am trying to deploy a Django 3.2.8 project using nginx and gunicorn. The problem is that the server cannot find the static. Because of this, the pages are displayed without css and images. I tried many solutions from the internet but nothing helped me. Thank you in advance for your time! at first im start this script (start_gunicorn.sh) #!/bin/bash source /root/myapps/zhanna_first_web/env/bin/activate exec gunicorn -c /root/myapps/zhanna_first_web/zhanna/gunicorn_config.py lawyer> gunicorn_config.py: command = '/root/myapps/zhanna_first_web/env/bin/gunicorn' pythonpath = '/root/myapps/zhanna_first_web/zhanna' bind = '185.46.8.164:8001' workers = 3 user = 'root' limit_request_fields = 32000 limit_request_field_size = 0 raw_env = 'DJANGO_SETTINGS_MODULE=lawyer.settings' /etc/nginx/sites-enabled/default server { listen 80; server_name 185.46.8.164; location /static { autoindex on; root /myapps/zhanna_first_app/zhanna/static; } location / { proxy_pass http://185.46.8.164:8001; proxy_set_header X-Forwarded-Host $server_name; proxy_set_header X-Real-IP $remote_addr; add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"'; add_header Access-Control-Allow-Origin *; } } Ubuntu responds to the launch of the start_gunicorn script with this output.

annotate an extra field but show just once in api response in django rest
I have to add an extra field using annotate in the get api. The field is something like count of a field of all the objects, not a particular object. And I want it to appear just once in the response of get api. If I use annotate, it appears on all the objects response. How can it be achieved?? My model: class Package(models.Model): location = models.CharField() bought_times = models.IntegerField(default=0) /....................../ Now if I use annotate something like this: qs = Package.objects.filter(....).annotate(whole_bought_counts=Sum("bought_times") or some logic) In the response it will come like: { id = 1, localtion = Paris, bought_times = 22, whole_bought_counts =72, } { id = 1, localtion = Miami, bought_times = 16, whole_bought_counts =72, } id = 1, localtion = Switzerland, bought_times = 24, whole_bought_counts =72, } I need the whole_bought_counts to appear just to appear once, because the count is used for the dashboard info only. Appearing several times will make it appear 100+ times which makes the api quite slow. isnt it?? -
Modal popup for Django DeleteView
I'm trying to have a modal popup asking for confirmation before deleting the object using DeleteView. So far, I've tried solutions from this thread using the following code. views.py class SessionCancelView( SuccessMessageMixin, LoginRequiredMixin, UserPassesTestMixin, DeleteView ): model = Session success_url = "/profile" success_message = "Session was cancelled successfully" # FIXME: success message not showing - eh maybe not necessary tho def test_func(self): session = self.get_object() if self.request.user == session.student: return True return False def get(self, request, *args, **kwargs): return self.post(request, *args, **kwargs) profile.html <!-- Modal --> <div class="modal fade" id="sessionDeleteModal" tabindex="-1" role="dialog" aria-labelledby="sessionDeleteModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Cancel Session</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> Are you sure you want to cancel this session? </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> <button class="btn btn-outline-danger" type="submit">Yes, Cancel</button> <form method="POST" action="{% url 'session-cancel' session.id %}"> {% csrf_token %}<input type="submit" value="DELETE"> </form> </div> </div> </div> </div> . . . {% for session in user_sessions %} {% if session.is_upcoming %} <div class="card bg-light mb-3" style="width: 18rem;"> <div class="card-header">{{ session.date|date:"F d [l]" }}</div> <div class="card-body"> <h5 class="card-title">{{ session.get_timeblock_display }}</h5> <h6 class="card-subtitle mb-2 text-muted">{{ session.weekday }}</h6> <p class="card-text">{{ session.helptype }}</p> <a class='btn btn-outline-secondary btn-small … -
Django: Unique IDs for each sub-model of a Model
I'm fairly new to Django, but I believe my question is more towards designing databases regardless of the framework or platform. Let me explain using following quick pseudo. I have following two models: class Issue(models.Model): title = models.CharField(max_length=60) status = models.IntegerField(choices=Status.choices, default=Status.OPEN) ... class Comment(models.Model): issue = models.ForeignKey(Issue, on_delete=models.CASCADE, related_name="comments") text = models.TextField() ... In my web app, I'm building a collection of Issues. Each issue is assigned a django's auto-generated unique ID number (pk), which is perfect. And for each issue there is a property comments which holds a collection of comments specific to this issue. Each comment also has a system-generated unique ID, but the sequence of this ID is not specific to the Issue model. Means if I create 3 comments in Issue #1 (comment #1, #2, #3), and then I create a comment under Issue #2, that comment's ID is set as #4 instead of #1. I understand that this is the way the data models are defined. What I would like to have is that whenever a new issue is created and a comment added, its ID should start from 1. I cannot define comment IDs manually by incrementing over the previous comment ID because … -
How to control the size of div by adding class using jquery?
sorry if the question isn't clear enough but let me explain what is happened to me. now I have 5 graphs that have been created by Pandas and want to use jquery to affect on grid system in bootstrap. all the divs have the following class "col-md-6" except the last child which has "col-md-12", what I would like to do is: to add "col-md-6" to the last child in case of the length of graphs are even number and remove the "col-md-12" from the last one. actually, this process is working and the class becomes added to the last child after the document is ready, however, the last graph does apply "col-md-12" and does not apply "col-md-6" even though, it has "col-md-6" but when I do a resize for the page the graph starts to apply "col-md-6" on it. the question is How can I apply the "col-md-6" dynamically without doing resize for the page? you can see the behavior before and after resize to understand what I mean exactly:- before do resize after doing a resize The code is like so:- ... <div class="col-md-6 error-graph"> {% if regular_group %} <div style=""> <div style="max-width: 100%;max-height: 100%"> {{ regular_group|safe }} </div> … -

Django access site name/url in template - views, contexts and settings
(It feels like "best practices" type of question, sorry if these don't belong here) I'm building a website which has user registration and password reset feature, both of which would send email to the user with a link to click to complete the respective process. While testing on a staging box, I used a dirty workaround in order finish the Proof Of Concept - hardcoded the website address in the template ) Needless to say, I want to fix this sooner rather than later. Searching around, found references to django.contrib.sites, which looks like a possible solution, though one thing bothers me - technically there's but one site, but with two stages, staging and production. I don't want to swim against the current, potentially abusing "sites", where another solution might apply. I've then considered another approach - add respective URLs to corresponding settings.py files, of which I already have a grasp - one for local, one for staging, and one for prod. The issue here is probably obvious - I don't think it's proper (or possible) to read the settings.py from templates, and trying to keep the solution as simple as possible, I'm using a few standard views, which means I … -
GET Request causes net::ERR_CONNECTION_REFUSED (Django/PostgreSQL)

How to create a test-only Django model in general (and with pytest-django specifically)
General issue: I have an abstract model that I want to test with a real model instance, however I don't want to have to completely restructure my project/test format. See these two answers for reference: First answer Second answer I want to A) Define models inside each test app folder and not define them inside the actual apps B) Not have an additional/separate apps.py and settings.py configuration for each test folder. I know this is possible because the django project has a very similar test structure like this, but they use a test run script that I can't entirely decipher. The test/ folder mirrors the app structure I have (which are blog/, projects/, richeditable/). backend ├── projects ├── blog ├── richeditable ├── tests │ ├── __init__.py │ ├── conftest.py │ ├── blog │ │ ├── ... │ ├── projects │ │ ├── ... │ └── richeditable │ │ ├── __init__.py │ │ ├── test_model.py │ │ ├── models.py <-------------- This defines a model that inherits from richeditable.models # richeditable/models.py class Draftable(models.Model): blah = models.IntegerField() class Meta: abstract = True # tests/richeditable/models.py class DummyDraftable(Draftable): additional_field = models.BooleanField() # class Meta: # app_label = "some_app" # ^--- Django does not seem to … -

Cant apply django migration that changes primary key name
I am trying to rename some models and fields that have names I do not like. I am using an mssql database. I have a very simple model.

How to update a foreign key's attribute after creation of object in Django Model
I'm creating a REST API using Django that has two models that relate to each other: Item and Attribute. An Item has Attribute as a foreign key.

TemplateDoesNotExist at / index.html (Django)
I'm currently trying to get my full stack app (React and Django 4.0) to deploy on Heroku, but when I load the landing page, I get a TemplateDoesNotExist at / index.html error on the page. Like so: However, I can get the django admin page to load just fine. From what I've seen so far, I think my current problem is in my TEMPLATES settings in my settings.py file, but nothing I have changed has worked for me yet. Here is some of the settings.py file: from pathlib import Path import os BASE_DIR = Path(__file__).resolve().parent.parent TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'build')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] I was following a tutorial since I'm new to Django and I changed my file structure from two directories (one for front-end and one for back-end) to just one like below: My index.html is still located in the public directory and I'm not quite sure if I need to make a templates folder and relay that path in my settings or not. Here's my urls.py: from django.contrib import admin from django.urls import path, include, re_path from django.views.generic import TemplateView from django.conf import … -

Настройка docker-compose.yaml для vue, redis и django [closed]
Я планирую запускать приложение одной командой из терминала. Однако при конфигурировании docker-compose.yaml столкнулся со множеством проблем и пробелов в своих знаниях. Составив наконец этот файл понял что работает только redis а остальное не запускается. Сам Django работает на postgresql, а redis нужен только для нормальной работы celery, которого я пока не хочу добавлять в docker Структура приложения docker-compose.yaml src/web/static/museum/(фронт приложения на vue.js) src/manage.py python/Dockerfile vue-js/Dockerfile python/Dockerfile FROM python:3.8 ENV PYTHONUNBUFFERED 1 RUN pip install poetry==1.1.8 && poetry config virtualenvs.create false WORKDIR /app COPY pyproject.toml .
