Why are my media files not being served in Django application with nginx?
I have a problem with my Django application which is deployed using gunicorn and nginx. I have a model for storing images in my sqlite database. class Image(models.Model): image_file = models.ImageField(upload_to="fucking_scraper/files/item_photos") item = models.ForeignKey(Item, on_delete=models.CASCADE) Here is my urls.py file urlpatterns = [ path("admin/", admin.site.urls), path("", include("fucking_scraper.urls")), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) and here are parts of settings.py file, related to serving files BASE_DIR = Path(__file__).resolve().parent.parent MEDIA_URL = "/media/" MEDIA_ROOT = "" STATIC_URL = "static/" STATICFILES_DIRS = [os.path.join(BASE_DIR, "fucking_scraper", "static", "fucking_scraper"), os.path.join(BASE_DIR, "fucking_scraper", "files", "item_photos")] STATIC_ROOT = os.path.join(BASE_DIR, 'static/') On a deployed website images are not displayed. I assume there is a problem with nginx configuration because before deployment it was working correctly in a debug mode. Here is how it looks like: server { listen [::]:80; server_name fwebsite.org; location /static/ { root /home/django/fwebsite.org; } location /media/ { root /home/django/fwebsite.org/fucking_scraper/files/item_photos/; } location / { include proxy_params; proxy_pass http://unix:/home/django/fwebsite.org/fucking_website.sock; } } I tried setting up location /media/ following instructions found on the internet but it didn't work for me and I am currently stuck. -

Flutter Exception "type 'String' is not a subtype of type 'int' of 'index'" when fetching filtered api data
I'm making an Android app with local Django Restful Api. I have 2 models in database, that are nested together, ShowsModel and DirectorModel. This is basically how my JSON looks like with GET function. [ { "id": 1, "name": "Shows name", "annotation": "Some long text", "image": "/media/images/poster.jpg" "director": { "id": 2, "name": "First name", "surname": "Last name", "image": "/media/images/portrait.jpg" }, }, ] I need to filter shows by director id and display them. I changed up views.py in my Django, and added some functions, like check_director = self.request.query_params.get('check_director', None) if check_director: queryset = queryset.filter(director=check_director) serializer = ShowsSerializer(queryset, many=True) return Response(serializer.data) It works, now I have this key parameter check_director, and when I add value 1, it shows only that data, which contains director with id 1. Now, the problem is in Flutter. I have director detail page, that requires id, which it gets from another screen. I use this function to get data from DirectorsModel in Django Api. Future<void> getDirectorInfo() async { directorModel = await APIHandler.getDirectorsById(id: widget.id); setState(() {}); } It works, no problem. But how do I fetch data from ShowsModel? I'm trying this function for api: static Future<ShowsModel> getShowsByDirector({required String director}) async { try { var uri = … -

How to build an NFC-based smart employee in/out management system with Django?
I am working on building an employee in/out management system that utilizes NFC tags for clock-in and clock-out operations. I want to implement this system using Django, but I'm unsure about the specific steps involved. I have come across some tutorials that demonstrate similar implementations using Google Sheets example The Best Employee Timesheet using NFCs and NFC-Based Employee Time Logging System. However, I would like to integrate the system with my Django application and sync the employee database with the data stored on the NFC tags. Now I'm particularly interested in the following areas: Communication between Django app and NFC tag: I'm unsure about how to establish communication between my Django application and the NFC tags. What libraries or technologies should I use? Are there any Django-specific considerations to keep in mind? Database synchronization with NFC tag data: I want to ensure that the employee database in my Django application stays synchronized with the data stored on the NFC tags. How can I achieve this synchronization? Are there any best practices or recommended approaches? If anyone has experience with building an NFC-based employee in/out management system using Django or has insights into the specific steps I outlined, I would greatly … -

Unable to generate downloadable PDF file from Django website hosted in apache
Im encountering an issue in generating a PDF file from a hosted django website. The website is hosted in apache thorough cpanel python web app. The website is basically a dashboard of all user submissions with a download button at the side. Once you click on the button, a dialog box will pop-up, prompting you to download the pdf file with user submission details. I followed this tutorial to get it to work: https://docs.djangoproject.com/en/4.2/howto/outputting-pdf/ I added some more code to it using pypdf and reportlab to handle the details from the database and add them to a pdf file to output it. The code works fine on my local computer, but when deployed to my hosting site, it returns a generic error response on my console and an uncommon error-like message saying io.UnsupportedOperation: fileno on my webapp stderr.log file. How my project is set up is that I have a javascript function that makes a GET request to a django function to generate the pdf file on the browser. Here are my code. javascript: function downloadPDF(id, date) { const csrftoken = getCookie('csrftoken'); $.ajax({ url: `/generate-pdf/${id}`, method: 'GET', headers: { 'X-CSRFToken': csrftoken, }, mode: 'same-origin', xhrFields: { responseType: 'blob' // Specify … -

How to fix bug when multiple accordions open in Bootstrap when quickly switching between them?
I'm trying to implement an accordion using bootstrap, where when a button is clicked, a collapse show occurs. It is important to understand that when one collapse is opened, the other must be closed. And it seems to work that way, but if I start switching between them quickly, I catch a bug where I have two collapse open at the same time. The Bootstrap documentation says that to achieve this effect, you need to specify the same data-bs-target, but as you can see from my code, this aspect is taken into account. Below I will attach all the required code, as well as a video with a demonstration of this bug. HTML <div class="container"> <div class="accordion" id="accordion"> <div class="steps"> <div class="step-item mx-auto"> {% for step in steps %} {% if step.id == 1%} <button class="step-button text-center" type="button" data-bs-toggle="collapse" data-bs-target="#Step{{ step.id }}" aria-expanded="true" aria-controls="collapse{{ step.id }}"> {{ step.id }} </button> {% else %} <button class="step-button text-center" type="button" data-bs-toggle="collapse" data-bs-target="#Step{{ step.id }}" aria-expanded="false" aria-controls="collapse{{ step.id }}" > {{ step.number_step }} </button> {% endif %} {% endfor %} </div> </div> <div class="card "> {% for step in steps %} {% if step.id == 1 %} <div id="Step{{ step.id }}" class="collapse show" data-bs-parent="#accordion"> … -
