How to get static files to work in Django | Favicon not getting loaded but appears when entering that directory
I'm having trouble trying to get my static files to work, I've already tried different answers for a long time and I'm getting confused what's the problem. I was trying to load my css with debug turned off, but I think its normal for the css not to appear since django doesn't load static files with debug turned off. My problem was when trying to put a favicon into my test website. I also think in the future I'll have complications with JS, etc.. main.html {% load static %} <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>Hello, Django</title> <!-- load staticfiles--> <link rel="stylesheet" href="{% static 'main.css' %}"> <link rel="shortcut icon" href="{% static "favicon.ico" %}}" type="image/png"> </head> <body> </body> </html> urls.py from django.urls import path from f1trackerapp import views from django.contrib.staticfiles.storage import staticfiles_storage from django.views.generic.base import RedirectView urlpatterns = [ path("", views.f1trackerapp, name="f1trackerapp"), path('favicon.ico', RedirectView.as_view(url=staticfiles_storage.url('favicon.ico'))) ] settings.py (stackoverflow doesn't let me post full settings.py code) ... from pathlib import Path import os # Build paths inside the project like this: BASE_DIR / 'subdir'.

HTML does not recognize CSS file - Django
I recently started working on my first python + django project and I'm working on some visual things, but I noticed that the HTML isn't recognizing my CSS file. I follow the documentation about How to manage static files but nothing worked. So, this is my settings.py #app definition INSTALLED_APPS = [ #personalizacao #'grappelli', #Configuraçoes principais 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles' ] #statics configs STATIC_URL = "/static/" STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static"), ] STATIC_ROOT = os.path.join(BASE_DIR, 'static/') STATICFILES_FINDERS = ( 'django.contrib.staticfiles.finders.FileSystemFinder', # 'django.contrib.staticfiles.finders.AppDirectoriesFinder', #causes verbose duplicate notifications in django 1.9 ) In my HTML I have {% load static %} <link rel="stylesheet" href="{% static 'css/styles.css' %}" /> And I can call the stuff that I have on the static/img folder with no problem So does anyone know what can it be? I don't know where to look anymore -
AWS EC2 Django Requests working from Public ipv4 address, but not Public ipv4 DNS address
Running a django project on an ubuntu 22.04 instance on a new account including a default VPC. Using a custom security group with 3 inbound rules: ipv6(http) on port 80, ipv4(http) on port 80, and ipv4(ssh) on port 22. Outbound rule is the same as default, ipv4(all) on all ports. No key pair was set. Running with gunicorn, nginx, and supervisor. sudo nginx -t shows no issues, supervisor err logs are empty. /var/log/nginx/access.log shows that the api is receiving requests from both sites with no difference in the logs besides codes 200 29 for the successful request from the public ipv4, and codes 404 197 for the failed request from the public ipv4 DNS. It's also worth noting that the public ipv4 DNS serves the default nginx page on the base url while the public ipv4 shows resource not found. There are no relevant errors in /var/log/nginx/error.log. -
Why is Heroku not updating my Django app's code?
I have a Django blog deployed by Heroku, statics served with S3 Bucket. A few days ago I realised that my changes are not shown in the actual code when I inspect it with Chrome's Inspector tool. I pushed them to the git repo and to heroku master. This project is for my thesis, so it would be really important to resolve this problem. Thank you very much to spend your time helping me in advance. This is one of my latest changes: Added a paragraph to a django signup form that the user can view my Privacy Policy before signing up to my blog. I attached the code from PyCharm: {% extends 'default.html' %} {% block content %} <h1>Signup</h1> <form class="site-form" action="/accounts/signup/" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Signup"> </form> <!-- Privacy Policy Link --> <p>By signing up, you agree to our <a href="https://www.termsfeed.com/live/d0e2bb42-feca-4abe-8051-afccfe402f6a">Privacy Policy</a>.</p> {% endblock %} The code from the actual website with Google's Inspector tool: <form class="site-form" action="/accounts/signup/" method="post"> <input type="hidden" name="csrfmiddlewaretoken" value="1P17fSXi3R2ihBMd17GqUPmx2pIsL4c855BnGwrhTbenlx4sKQea1nJTuCK0Apei"> <label for="id_username">Username:</label><input type="text" name="username" maxlength="150" autofocus="" required="" id="id_username" data-siid="si_input_0"><br><span class="helptext">Required. 150 characters or fewer.

AWS EC2 instance public ipv4 DNS address pointing to private ipv4 address instead of public ipv4 address
Running a django project on an ubuntu 22.04 instance on a new account including a default VPC. Using a custom security group with 3 inbound rules: ipv6(http) on port 80, ipv4(http) on port 80, and ipv4(ssh) on port 22. Outbound rule is the same as default, ipv4(all) on all ports. No key pair was set. Running with gunicorn, nginx, and supervisor. sudo nginx -t shows no issues, supervisor err logs are empty, and accessing the api through the public ipv4 address http://xx.xxx.xx.xxx works properly, serving content when requested, with the base url showing Not Found. Accessing through the private ipv4 address does not respond. The problem is that when accessing through the public ipv4 DNS address, http://ec2-xx-xxx-xx-xxx.us-east-2.compute.amazonaws.com, where the x values match the public ipv4 address, the site only serves the default nginx page. Running nslookup on the DNS address returns the private ipv4 address. Why doesn't the DNS address point to the public ipv4 address? And why does it serve content at all if it points to the private ipv4 address which doesn't respond? Here are the configurations I used for nginx: Changed nginx.conf user to root, and created/linked django.conf in /etc/nginx/sites-available and /etc/nginx/sites-enabled: `server{ listen 80; Server_name [public … -

Django cripsy form with a custom template for button
I have a need for a <button> element for my form submit instead of the layout helper Submit() input with Django and django-crispy-form. If I use {{ my_form|crispy }} I'm able to do this. However, with this method all of the other layout elements in the form are ignored. If I switch back to {% crispy my_form %} I get the layout back, but then my custom HTML button is ignored. Is there any way to have a custom HTML submit button while using the Layout helper? Note: If I add the HTML button below the crispy tag the button renders outside of the form, and I cannot iterate through the form fields in the template because my Layout in the Django form is very complex. -
React chat app messages don't have different className
I am making a chat app with django channels and react. I save the messages in state. When a new message is made I want it to have the className of the current user. The problem is that all messages have the className of the user reading them even if they were written from other. For example I am sending messages from 2 different browsers. The one is logged as first and the other as second. If first sends a message it will appear with a className of first. But for second this message will appear with a className of second chatSocket.onmessage = function(e) { if (ran == true) { const data = JSON.parse(e.data); setMessages(old => [...old, <p ref={oneRef} id={currentUser[0]?.username} className={currentUser[0]?.username}>{data.message}</p>]) } } What can I do to solve this. -

Is it normal that Django ORM makes a DB call on every object in a List View?
I'm facing a problem of extra DB calls to retrieve object's data. I have a model: class Post(models.Model): profile = models.ForeignKey(Profile, related_name="posts", on_delete=CASCADE) project = models.ForeignKey(Project, related_name="posts", on_delete=CASCADE) body = models.TextField(verbose_name="Content", max_length=1300) liked_by = models.ManyToManyField(Profile, related_name="post_likes", blank=True) date_published = models.DateTimeField(auto_now_add=True, verbose_name="Date published") date_modified = models.DateTimeField(auto_now=True, verbose_name="Date modified") is_active = models.BooleanField(verbose_name="Active", default=True) tags = TaggableManager(blank=True, related_name="posts") I am calling a View to list all Post objects (currently, there are 4) but getting 4 extra queries to posts_post for each entity. Is that normal behaviour to make an individual DB call on each entity in DB (not related entities but the root entities).

Issue in Django Prefetching same objects, but with different dates
I know there has to be a simple way to get around this, but I am having an issue figuring it out. Overall I have a semi-complex Prefetch giving me general ledger entries between a specific date range. Works great, and gives me the data I need. However, now I need to figure out a calulation based on any date before the selected date range but I am unable to prefetch the items again, even while casting to_attr=... from those dates. The error I get is: lookup was already seen with a different queryset. You may need to adjust the ordering of your lookups.

Django serve static files e.g. favicon.ico without `{% load static %}`
I have successfully followed the popular solution for serving static files in Django: I have /myproject/myapp/static/favicon.ico I use <link rel="icon" href="{%static 'favicon.ico' %}" /> in my html template But if I omit the <link rel...> from html then the browser will by default try to GET /favicon.ico which predictably logs Not Found: /favicon.ico How can I tell Django "if anything in urlpatterns does not match the GET string, and that GET string matches a file within a certain directory, just serve that file"? (Then I would be able to write e.g. <script src="/script.js"> and have /myproject/myapp/static-or-wherever/script.js be served without using {% use static %} in a template -- e.g. if I browse to http://my-site.com/script.js manually.) -

django if else template tag using object from with template tag
I have an if/else statement that determines which button will be displayed in my base.py template. From doing my research I think I am on the right path, but regardless of if the enddate field is null or populated, the endcast button displays. model: class Cast(models.Model): id = models.AutoField(db_column='Id') startdate = models.DateTimeField(db_column='StartDate') enddate = models.DateTimeField(db_column='EndDate') class Meta: managed = True db_table = 'Cast' verbose_name_plural = "Cast" get_latest_by = "pk" template block: <div class="top-button-container stickey-top"> {% with last=Cast.objects.latest %} {% if last.enddate %} <button type="button" class="btn btn-danger btn-lg btn-block"> <a class="nav-link" href="{% url 'caststart' %}">Start Cast</a> </button> {% else %} <button type="button" class="btn btn-danger btn-lg btn-block"> <a class="nav-link" href="{% url 'cast_end' %}">End Cast</a> </button> {% endif %} {% endwith %} </div> I was expecting the "start cast" button to render when the last objects enddate field is populated. The "end cast" button should render when the enddate field is none. It currently renders the "end cast" button regardless of the last objects enddate field value.
