Django is not refreshing content without server start
I am working on DjangoRest Framework, if I update values from the API, and see the content on the frontend, the changes are not getting reflected without server startup. For debugging, I also directly changed the value in the database, but the changes are not getting reflected either in this case too. What could be the reason behind this? Can someone point me out in the right direction? I read about it and someone told this is happening because of .pyc files I even deleted them. But nothing solved my issue yet. How can i resolve it ? -
Django model choices from database, another model
I'm trying to figure out how to allow for a model to take only certain values. But I can't use IntegerField with choices option because it's product database with couple thousand products. To be more precise- I'm trying to create app which manages product orders. For now my models are: class Order(models.Model): timestamp = models.DateField(auto_now_add=True) komentarz = models.CharField(max_length=150, unique=False) class Product(models.Model): order = models.ForeignKey(Order, on_delete=models.CASCADE) r = models.CharField(max_length=50, unique=False) s = models.CharField(max_length=50, unique=False) p = models.CharField(max_length=50, unique=False) I created another app with product database, it contains around 3000 records. class ProductBase(models.Model): r = models.CharField(max_length=50, unique=False) s = models.CharField(max_length=50, unique=False) p = models.CharField(max_length=50, unique=False) Basically I want to allow Product model to take values inside database made thanks to ProductBase model. Any idea what should I use? -

Which template tag to include an image stored using django-storage[dropbox]
I try to build my first application with Django, and use django-storage to store my media on dropbox: DEFAULT_FILE_STORAGE = 'storages.backends.dropbox.DropBoxStorage' DROPBOX_OAUTH2_TOKEN = ---- mytoken ---- DROPBOX_ROOT_PATH = 'media' It works well to upload and display the images using the models directly (e.g. {{ object.photo.url }} in the html template works) However, how can I create a link to the image in the template if I have no object. Something like <img src="{{media_url}}/myimage.jpg"> does not work as media_url points to localhost (on my local server). Is it needed to redefine media_url or is there another tag to use? -
How to configure NGINX for Vue and Django?
I was following this tutorial to create backend and it worked. I made simple a Django REST admin panel to upload images, it worked. Then i created Vue frontend app, run 'npm run serve' while in 'VScode remote' and it worked (images are fetched from django and styled by Vue in my localhost). The PROBLEM is it's not obvious how to make all this work in production vps server (i mean from Vue 'dist' folder after 'vue run build'). Everything i tried just gives me 404 error or ruins Django admin panel. Here are my NGINX settings : server { server_name kruglovks.xyz www.kruglovks.xyz; client_max_body_size 100m; location = /favicon.ico { access_log off; log_not_found off; } location /static { root /home/kirill/myprojectdir/myproject; } location /media { root /home/kirill/myprojectdir/myproject; } location /dist { try_files $uri $uri/ /index.html; alias /home/kirill/myprojectdir/myproject; } location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } Vue router is set to history mode. Please, i need some info how to make Vue work in this configuration. P.S. Maybe there is alternative way of using Vue alongside Django? Thank you so much and have a nice day! -
Data too long for column when creating user

I am currently new in programming (only 4 months coding) and mostly spent time with Python, could find time to properly learn front-end. So my problem is I can`t center LOGIN block in the page.

Optimize DB requests in Django
I have a page view in Django set up as follows: blog = get_object_or_404(Blog, subdomain=extracted.subdomain) all_posts = Post.objects.filter( blog=blog, publish=True).order_by('-published_date') nav = all_posts.filter(is_page=True) posts = all_posts.filter(is_page=False) This causes the DB to be accessed 3 times. I'm trying to optimize this to only access the DB once. The following snippet reduces the number of calls to 2, but I'm sure there is a better way than this that I don't know about. blog = get_object_or_404(Blog, subdomain=extracted.subdomain) all_posts = Post.objects.filter( blog=blog, publish=True).order_by('-published_date') nav = [] posts = [] for post in all_posts: if post.is_page: nav.append(post) else: posts.append(post) As far as I understand, prefetch_related and select_related work inversely and I'm unsure how to implement them in this context. My models are set up as follows: class Blog(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True) title = models.CharField(max_length=200) ... class Post(models.Model): blog = models.ForeignKey( Blog, on_delete=models.CASCADE, related_name='post') title = models.CharField(max_length=200) ...

Static Media Failure with NGINX and Gunicorn
Hello and thanks for taking time to read this request for help. I am installing a web application called Netbox, which is built on Django. A basic Gunicorn is front-ended with NGINX in a rather simplie configuration. The problem I'm running into is that the web application reports that it is unable to load any of the static files, and I can validate that I'm getting a 404 for these requests. I have validated that I can view the correct files in the /static/ path referenced in the NGINX path /opt/netbox/netbox/static, and the permissions are correctly set as well. Since this is a Django web app, I have performed a simple test with the built-in test web server and all the static files are correctly rendered; this is almost certainly an issue between Gunicorn and my NGINX configuration. nginx.conf server { listen 443 ssl; # CHANGE THIS TO YOUR SERVER'S NAME server_name netbox.example.com; ssl_certificate /etc/ssl/certs/netbox.crt; ssl_certificate_key /etc/ssl/private/netbox.key; client_max_body_size 25m; location /static/ { alias /opt/netbox/netbox/static/; } location / { proxy_pass http://127.0.0.1:8001; proxy_set_header X-Forwarded-Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto $scheme; } } server { # Redirect HTTP traffic to HTTPS listen 80; server_name _; return 301 https://$host$request_uri; } gunicorn.py bind = … -

Apache HUE, can login using REST API, but the rest doesn't work
I'm struggling with Apache HUE Rest API and django csrf. The problem is that I can kind-a login, but the rest doesn't work. I always get redirected to login page.

What's the correct way to use fcm-django using a custom Device-info model or a possibility to extend FCMDevice with more attributes. For example, I need to store into the device info some additional fields like language, position (lat/lng), app version, vendor etc. I'm new for FCM but for me, at the moment, It's not very clear the device registration flow. My current project is a backend service for mobile apps. So, I have some REST service using djnago-rest-framework. I already have an API to register/update a mobile device. Can I reuse it adding the FCM registration-id? -
AttributeError: Cannot use remove() on a ManyToManyField which specifies an intermediary model. Use songs.Playlist_Activity's Manager instead
I followed the documentation on figuring out how to remove an item in the manytomanyfield below but it doesn't seem to work and I am getting an attribute error. The remove method works totally fine without the intermediary model. models.py class Song (models.Model): author=models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, default=1) timestamp= models.DateTimeField(auto_now_add=True, editable=False) songname = models.CharField(max_length=500, null=False, blank=False) tags = TaggableManager() def __str__(self): return self.songname class Playlist (models.Model): name = models.CharField(max_length=150, null=False, blank=False) author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, default=1) song = models.ManyToManyField(Song, through='Playlist_Activity') class Playlist_Activity(models.Model): song= models.ForeignKey(Song, on_delete=models.CASCADE) playlist= models.ForeignKey(Playlist, on_delete=models.CASCADE) timestamp= models.DateTimeField(auto_now_add=True, editable=False) class Meta: ordering = ('timestamp',) Views.py @login_required def Playlist_Remove(request, id, P_id): Playlist_Activity p = Playlist.objects.get(id=P_id) s = p.song.get(id=id) p.song.remove(s) return redirect('account') -
How to change from request.site to Site._find_for_request(request) in wagtail 2.9
I've recently upgraded my wagtail app to the latest version, version 2.9, now since the wagtail site middleware has been deprecated I'm having trouble getting my site to work. I was using a request.site now wagtail 2.9 uses Site._find_for_request(request) How do I change my current code to work with the latest wagtail version?

Django crispy form layout helper does not work
I'm trying to set the html layout of my forms using the helper and layout of crispy form.
