Django Choices model field with choices of classes

Best Solution for connecting to 2 diffreent databases with 2 diffrent access in Django by using ORM or query Script
I want to connect my django project to 2 diffrent databases, one of them is MS-SQL with read-only access and the other is a PostgreSQL with full access what I want to do is read from the MS-SQL by using celery beat and write the aggrigated data on the Postgres what is the best solution to update my Postgres DB with the most performance? What is the most sample way which is already said in django documentation is this: https://docs.djangoproject.com/en/5.0/topics/db/multi-db/ I want to know that is if i use router.py file is better of just create an API which I read the some functions as a python script which are contatains the SQL query and insert or update them into the PostgreSQl What is the best solution? -
Custom save() method not working any more in Django 5.0.4
I have this custom save() method in mt admin.py: def save_model(self, request, obj, form, change): if obj._state.adding: obj.added_by = request.user return super().save_model(request, obj, form, change) After a recent update this is not working any more; indeed, when I hit 'save' on the backend I get no errors and the data is not saved on the database. It has worked until a recent update (I think up until 5.0.2). -
What is the Django logic flow to show pdf inside HTML template after click the given link
I'm using Django to create a website to public my post, all of my post is pdf. As usual, I defined my view and view logic, it returns a context dictionary views.py class PageView(TemplateView): def get_context_data(self): context = super().get_context_data(**kwargs) highlightObject = Post.objects.filter(is_highlight = 1).order_by('-created_on') context['highlight'] = highlightObject return context Then, on my html file {% extends "base.html" %} {% for row in highlight %} <h3 class="mb-auto">{{ row. Title }}</h3> <div class="btn-group"> <a href="{{ row.pdfFile.url }}" class="icon-link">Reading more</a> </div> {% endfor %} Until now, when cliking on the "Reading more", it changes to pdf Viewer, but I want to show pdf viewer inside html template, for example, it should change to other html file which extend the template from base.html and show pdf viewer using path row.pdfFile.url So, how to write a new html file for reading pdf from directory row.pdfFile.url Or, if there is any other way to solve this problem.

Custom User Model having ForeignKey to Customer with dj-stripe
I would like to have a Custom User Model in my django application, featuring a column to hold reference to Customer objects coming from stripe, being synced via dj-stripe. So my approach was to extend as follows: from django.contrib.auth.models import AbstractUser, UserManager from django.db import models class StripeUserModel(AbstractUser): objects = UserManager() customer = models.ForeignKey("djstripe.Customer", null=True, blank=True, on_delete=models.SET_NULL) Setting the standard django User model to: AUTH_USER_MODEL = "billing_stripe_app.StripeUserModel" When I start with a clean new database by deleting the SQLite file and running python manage.py makemigrations, I observe following error: django.db.migrations.exceptions.CircularDependencyError: billing_stripe_app.0001_initial, djstripe.0001_initial, djstripe.0008_2_5, djstripe.0009_2_6, djstripe.0010_alter_customer_balance, djstripe.0011_2_7 Without the customer field in StripeUserModel, everything works. I wonder how to resolve this. I have run into circular dependency in Python before. It completely makes sense. In my application (billing_stripe_app), I reference dj-stripe customer field. And apparently this one relies on the AUTH_USER_MODEL user model itself again, creating that circular dep, as can be seen from the djstripe migration file 0001_initial.py (excerpt below). ...

Django Mediapipe application: how to manage delays in realtime video processing?
I'm developing a Django application which opens the client camera via JS using navigator.MediaDevices.getUserMedia(), send a blob to the server through websocket and then the server should process the images through mediapose library. I'm using the following three functions respectively to: convert blob to cv image def blob2image(bytes_data): np_data = np.frombuffer(bytes_data, dtype=np.uint8) img = cv2.imdecode(np_data, cv2.IMREAD_COLOR) if img is None: raise ValueError("Could not decode image from bytes") return img extract markers from the img def extractMarkers(image, pose, mp_drawing, custom_connections): image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB) results = pose.process(image) mp_drawing.draw_landmarks( image, results.pose_landmarks, connections = custom_connections, ) return image, results convert back the annotated image to b64_img def image2b64(img): _, encoded_image = cv2.imencode('.jpg', img) b64_img = base64.b64encode(encoded_image).decode('utf-8') return b64_img The code runs, but keeps accumulating delay during the streaming. Is there any way to drop the buffer or to improve the performance of the code? I tried locally the code for extracting markers extractMarkers(), without using the Django server application getting images coming from a local camera and it works smootly. I also tried to use the Django application to get the images from the client and sending them to the server through websocket and then only sending back to the client the images … -
Web application using gunicorn in nginx server not working
I had 3 apps in a server running on Ubuntu 22.04. The first one was a Django app, the second a Flask appp under a subdomain and the third one a FastAPI under another subdomain. When I tried to add a fourth one (Flask) I don't know how I messed up but now none of them work. All the apps run perfectly in my computer. When I try to access the page through the browser in my computer it returns ERR_CONNECTION_REFUSED and when accessing throught my phone it returns a 502 Bad Gateway nginx/1.18.0 (Ubuntu) error.

Issue Adding "django.contrib.gis" to INSTALLED_APPS in Django
I'm currently developing an application using Django and aiming to integrate geospatial functionalities by adding "django.contrib.gis" to my project's INSTALLED_APPS. However, upon adding this module to INSTALLED_APPS in the settings.py file, I encounter the following error: django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried "gdal307", "gdal306", "gdal305", "gdal304", "gdal303", "gdal302", "gdal301", "gdal300", "gdal204"). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings Despite having the GDAL library installed in the directory C:\Program Files\PostgreSQL\16\gdal-data, specifying the GDAL_LIBRARY_PATH in the settings.py file doesn't seem to resolve the issue. Additionally, I have installed PostGIS via the Application Stack Builder in PostgreSQL. I'm seeking guidance on how to resolve this issue and successfully integrate "django.contrib.gis" into my Django project. Any insights or suggestions would be greatly appreciated. Thank you! -

Internal Server Error when Querying Orders: ValueError Must be User instance
I encountered an Internal Server Error while querying orders in my Django application. The error message indicates a ValueError: "Must be User instance." This occurs when filtering orders by customer_id. I'm developing a Django application where users can place orders. I have models for Order, Customer, and User. Each order is associated with a customer, and customers are linked to users through a foreign key relationship. I have a viewset to handle order queries, and I'm trying to filter orders based on the customer_id. However, when attempting to filter, I encounter a ValueError stating that it must be a User instance. 1.Reviewed the models and viewset code to ensure proper relationships and filtering. 2.Checked the queryset and filtering logic in the viewset's get_queryset method. 3.Examined the Customer and User models to verify the foreign key relationship. -

Django create several container columns in a template and fill it with several values from QuerySet
I'm pretty a newbie in Web-Development, so I've met some difficulties while trying to connect html-templates with Django code. My plan for a certain page of my projected site is roughly to have a header on above, then lower there are 3 column-shaped containers (left to right, representing, i.e., different groups) filled with names of members of those groups (with vertical alignment, each member in a separate little container with photo, name and description). I thought that, as I use Django, it would be stupid to hard-code all the members into containers, and there probably are some methods to fill those columns from the code. I used cycles. Here is the template ("core" is a name of the app, templates are located in project/core/templates/core directory): {% extends 'core/base.html' %} {% block content %} <h1>{{title}}</h1> <div>Characters</div> <div> {% for fac in factions %} {% if fac == outers %} <div> <h2>{{fac}}</h2> {% for char in fac %} <div> <h3>{{char.name}}</h3> <h3>{{char.description}}</h3> </div> {% endfor %} </div> {% endif %} {% if fac == resistance %} ... {% endfor %} </div> {% endblock %} File core/models.py: class Character(models.Model): FACTION_CHOICES = ( ('outers', 'Outer World'), ('resistance', 'Resistance'), ('neutrals', 'Neutral characters'), ) name = models.CharField(max_length=100) … -
How to get rid of django.db.utils.OperationalError: no such table?
I'm developing this app in Django where I can't generate the migrations under any circumstances. I have tried other posts on SO, I have spent hours on ChatGPT, but there's no progress. After defining the single model, views and urls, my project is always returning django.db.utils.OperationalError: no such table: vini_rest_plotdata in the code that I will provide below.

'The request signature we calculated does not match the signature you provided' in DigitalOcean Spaces
My django app saves user-uploaded files to my s3 bucket in DigitalOcean Spaces(using django-storages[s3], which is based on amazon-s3) and the path to the file is saved in my database. However when I click the url in located in the database it leads me to a page with this error: The request signature we calculated does not match the signature you provided. Check your key and signing method.

Kong 502 Bad Gateway
I have two VMs. One is running an Apache server with a Django API and the other is running Kong. The two VMs are on the same network and can ping each other, and I can access the Django site on my browser from my Kong VM. I have configured the Kong route to point specifically to the local IP address on the network (192.168.x.x) instead of localhost. On the Kong VM I can do curl requests directly to the API just fine, and I can access the site on my browser, and the test route to httpbin works fine as well. But I still continue to run into this error when I try to access the API through my service. I'm running Kong as is, no docker stuff I tried getting the logs and got no information other than the Bad Gateway stuff, I've triple checked and verified that the routes are pointing to the correct local IP address and route and not localhost, still nothing I also have a web application firewall setup (Modsecurity) but disabling the firewall doesn't fix the problem and no relevant error logs show up that might suggest the firewall is blocking my requests … -
How to optimize a bulk query to redis in django - hiredis
I am porting a rest/graphql api from a Java project to Django in Python. We are using redis in both. We have one endpoint that is rather large (returns several MB). In this endpoint we construct a key and if that key exists in redis we return that data and skip past the other logic in the endpoint. I have deployed the api to a development environment. The Java version of this endpoint returns data between 4-5 seconds faster than the python version. I recognize some of this is that Java is a compiled language vs Python which is interpreted. I'm aware that there are a host of other differences, but I'm trying to see if there is any low hanging fruit that I can pick to speed up my Python api. I ran across an optimized library named hiredis. The website says the library speeds up multi-bulk replies, which is my use case. I repeatedly hit an endpoint that returns a large amount of data. Hiredis is supposedly a parser written in C. I have redis-py and django-redis installed. I read that I need to pip install hiredis. One source says hiredis will automatically be detected and just work … -
How can I show and hide Like/Unlike buttons using Javascript in my Web app?
I'm doing online course CS50W by Harvard and building a web app similar to twitter. When user sees a post I need to show the user Like or Unlike button depending on user liked it or not. There's also a counter showing how many users liked the post so far. I am able to update the counter if the user liked or unliked the post, but I'm having problem with the code showing or hiding the buttons. Here's my code: models.py class Post(models.Model): """ Model representing a post. """ user = models.ForeignKey(User, on_delete=models.CASCADE) content = models.TextField() timestamp = models.DateTimeField(auto_now_add=True) no_of_likes = models.IntegerField(default=0) def __str__(self): return f"Post {self.id} by {self.user.username} on {self.timestamp}" class Like(models.Model): """ Model representing a like. """ user = models.ForeignKey(User, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return f"{self.user} likes {self.post}" urls.py path("", views.index, name="index"), path("like/<int:post_id>", views.like, name="like"), path("unlike/<int:post_id>", views.unlike, name="unlike"), views.py def index(request): """ Home page. """ posts = Post.objects.all().order_by('-timestamp') paginator = Paginator(posts, 5) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) likes = Like.objects.all() # Make a list of liked posts. liked_posts = [] try: for like in likes: if like.user.id == request.user.id: liked_posts.append(like.post.id) except: liked_posts = [] return render(request, "network/index.html", { "posts": posts, "page_obj": … -
Errors in Importing assets folder with static url in React parcel project
I am trying to serverside render a react page using Django. The server-side rendering is working fine for normal react components. The project is using parcel to auto-build javaScript files so that Django could render them. This is the command I am using to compile react to Js. "scripts": { "watch": "parcel watch src/index.tsx --public-url /assets/" } I am new to the parcel, So sorry for the poor framing of the problem and/or any wrong terminology. The problem comes whenever I try to import an assets component in my assets folder into my react components. The import statement in my react code is working fine but I am getting an error in the import statements of the assets folder telling the file path for import is wrong. Here is the below screenshot of the issue. enter image description here @parcel/core: Failed to resolve 'assets/theme/base/typography' from './src/assets/theme/index.js' C:\profitional\BRAVO\Server\assets\src\assets\theme\index.js:23:24 22 | import breakpoints from "assets/theme/base/breakpoints"; > 23 | import typography from "assets/theme/base/typography"; > | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 24 | import boxShadows from "assets/theme/base/boxShadows"; 25 | import borders from "assets/theme/base/borders"; Done in 689.72s.
