Django + React Development Setup for a Hybrid App
I'm using Django + React hybrid setup. Django does not simply act as a backend to API but actually renders pages. The setup works in production with some urls routed to Django's templating system and others (starting with 'app/') rendered from index.html + static files from React build. This works in production. However, I'm trying to get Django development server (localhost:8000) work with react development server (localhost:3000) as follows. Django backend Urls.py urlpatterns = [ # React urls re_path(r'^app/.*',views.application,name='application'), # Django urls path("", include("my_app.urls")), ] Views.py def application(request, upstream='http://127.0.0.1:3000'): upstream_url = upstream + request.path with urllib.request.urlopen(upstream_url) as response: content_type = response.headers.get('Content-Type') # print('CONTENT TYPE: ',content_type) if content_type == 'text/html; charset=UTF-8': response_text = response.read().decode() content = engines['django'].from_string(response_text).render() else: content = response.read() return HttpResponse( content, content_type=content_type, status=response.status, reason=response.reason, ) React frontend App.js function App() { const HomePage = () => { return (<h1>Home Page</h1>); } const TestPage= () => { return (<h1>Test Page</h1>); }; return ( <BrowserRouter> <Routes> <Route path="app/" element = {<HomePage/>}/> <Route path="app/test" element = {<TestPage/>}/> </Routes> </BrowserRouter> ); }; .env PUBLIC_URL = app Both /app and app/test urls are accessible on port 3000. However, on port 8000 where Django development server is running I can only get /app while … -
Updating Cart Total Amount Dynamically After Adding Items with AJAX in Django is not working properly
I created a cart item total section for my website <div class="col-md-4"> <div class="cart-item total-section"> <h3>Subtotal: <span class="total">$50.00</span></h3> <h3>Discount: <span class="total">$50.00</span></h3> <h3>Shipping: <span class="total">Free</span></h3> <h3>Total: <span class="total">{{cart_total_ammount}}</span></h3> <button class="btn btn-checkout">Proceed to Checkout</button> </div> </div> In the above code I am taking total ammount of the cart In " <h3>Total: <span class="total">{{cart_total_ammount}}</span></h3> " this line for this I created a javascript file So, In function.js: $("#add-to-cart-btn").on("click",function(){ let quantity=$("#product-quantity").val() let product_title=$(".product-title").val() let product_id=$(".product-id").val() let product_price = $("#current-product-price").text() let product_image = $(".product-image").val() let product_pid=$(".product-pid").val() let this_val=$(this) console.log("Quantity:", quantity); console.log("Id:", product_id); console.log("PId:", product_pid); console.log("Image:", product_image); console.log("Title:", product_title); console.log("Price:", product_price); console.log("Image URL:", product_image); console.log("Current Element:", this_val); $.ajax({ url: '/add-to-cart', data: { 'id': product_id, 'pid': product_pid, 'image':product_image, 'qty': quantity, 'title': product_title, 'price': product_price }, dataType: 'json', beforeSend: function(){ console.log("Adding products to cart"); }, success: function(res){ this_val.html("Go to Cart") console.log("Added products to cart"); $(".cart-items-count").text(res.totalcartitems) $(".total").text(res.cart_total_ammount) //#p } }) }) In the above javascript file you can see that I created the cart_total_ammount section.

Blacklisting Network Range on django-blacklist
I've noticed recently that my django-website is being crawled by a number of spammy bots, so while looking for a way to block this IP-range I came across django-blacklist. It works well for the most part, and I've successfully blocked single IPs, but when I tried to block a range (51.222.253.0 - 51.222.253.255), it seems to be unsuccessful. My inputs were: Address = 51.222.253.0 & Prefixlen = 24 (see image below). I've read the docs, and can't seem to get more clarity on this topic, however, this isn't a strong suit of mine so let me know if I've done something wrong. All help is appreciated! -
Django application experiencing "CSRF token missing" error specifically for POST requests when deployed with Nginx and Gunicorn
I've deployed a Django application using Nginx and Gunicorn, and I'm encountering a "CSRF token missing" error specifically for POST requests.

Django Adding Square Brackets In Admin-Related Views
I am hosting two Django applications on a webserver and I recently upgraded all my packages to more recent versions, along with bringing the project to Python 3.12, which was generally beneficial. In doing so, I noticed that square brackets ("[]") started appearing in seemingly random views associated with admin views. To be specific, when looking at individual models in the admin view AND on the sign-in page, which I believe Django admin heavily handles. It's not mission critical to solve, and there's nothing in the source code that I know of that would cause this, and no code changes were made apart from upgrading versions. I would think it's some random setting I have to turn off but I've spent a good amount of time trying to figure it out. Admin Model View Example 1 Admin Model View Example 2 Admin Login Standard Login I've tried going in a bringing the version down on a couple of packages, but there a multitude of packages in the dependencies and for the sake of where I'd like to take the project, I'd want it to use updated versions of packages as there are certain features I can't utilize properly unless both … -

How to configure Apache to deploy a project with Django and React?

How can change the primary key in a django model so that other dependent models are also affected and the changes are synced to the postgresql db
I have a django project with a database table that already contains data. The models: class Foo_A(models.Model): field1_pk = models.CharField(max_length=50) field2 . . fieldN_newpk = model.CharField(max_length=50) Data in field1_pk and fieldN_newpk are exactly the same. Lets say I have other models that reference fieldN_newpk as foreign key. I would like to rename a fieldN_newpk in this Foo_A model, without losing any data. This change should also be reflected in my other dependent models. I want to change the primary key from field1_pk to fieldN_newpk I want these changes to be reflected in my postgresql database as well I have seen other answers related to renaming of a model Also Is there a safe way/safe mode to try out these changes/migrations before actually trying on the original codebase -
Synchronizing a Django database with a Realm or Core database in an iOS app
I'm working on an iOS app that needs to synchronize data with a Django backend. The backend uses Django ORM and exposes data through a RESTful API built with Django REST Framework. On the iOS side, I'm using Realm or Core in future as the local database. I need guidance on how to implement synchronization between the Django database and the Realm or Core database in my iOS app. Specifically, I'm looking for advice on the following: How to design the synchronization process to ensure data consistency and integrity. Strategies for fetching data from the Django API and storing it locally in the Realm database. Techniques for handling conflicts between local and server data. Best practices for optimizing synchronization performance and reliability. Recommendations for error handling and retry mechanisms in case of network failures or server errors. Any security considerations or precautions I should take when implementing data synchronization. I would appreciate any insights, sample code, or references to relevant resources that can help me implement robust and efficient data synchronization between my Django backend and iOS app using Realm. Thank you! Some advices who work with -
How to use node modules within a Django app
I developed a web map app using Django. I used Leaflet for the map and I'd like to add some Leaflet plugins that are meant to be installed using npm. I'm new to node (I've only used it in Development during my classes) and have never used it in Production or with Django. I'm wondering if I have to configure anything else in my project or if I can just npm init and then npm install anything. I suppose I'd have to add node_modules to my .gitignore but I'm not sure how should I manage the static files generated by node and how should I import modules into my django templates. I'd be using Node only for front-end stuff, all my back-end is managed by Django. I haven't installed anything yet as I'm afraid I'll break my web. -

Why am I getting DoesNotExist for the parent model in save_related
I am firing a celery task in save_related that takes the parent object id and does a get query to obtain the instance for use. Problem is some of the get queries are failing with DoesNotExist. This doesn't make sense to me because the Django docs clearly state that "Note that at this point the parent object and its form have already been saved.". Also why are others not failing? I am about to experiment with what happens when I call super().save_related(...) before the celery task but I don't think that should be an issue because of the note above. Django==4.2.3 -

Connecting a Django project that is hosted on a Virtual Machine with Nginx and Gunicorn
I'm new to deploying applications. Currently, I'm hosting my Django project on an Ubuntu virtual machine with IP address 192.168.xxx.xxx. It is hosted on a physical service with public IP address of 202.xxx.xxx.xxx (using port 8080). I have gunicorn and nginx installed and incorporated, and they're running properly as sudo systemctl status gunicorn and sudo systemctl status nginx show that they're running with no errors. However, when I try to access the public IP address 202.xxx.xxx.xxx:8080, I'm getting the default Nginx page. As for how I setup my gunicorn and nginx, I followed the guide posted here: https://medium.com/@muhammadali_12976/deploying-django-on-a-local-virtual-machine-virtualbox-with-nginx-and-gunicorn-369f70937913 Here's the gunicorn.socket file: [Unit] Description=gunicorn socket [Socket] ListenStream=/home/myProject/myProject.sock [Install] WantedBy=sockets.target Here's the gunicorn.service file: [Unit] Description=gunicorn daemon Requires=gunicorn.socket After=network.target [Service] User=myUserName Group=www-data WorkingDirectory=/home/myProject ExecStart=/home/myProject/env/bin/gunicorn --access-logfile - --workers 3 --bind unix:/home/myProject/myProject.sock core.wsgi:application [Install] WantedBy=multi-user.target Here's the contents of my /etc/nginx/sites-available/myProject file server { listen 80; server_name 192.168.xxx.xxx; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/myProject; } location / { include proxy_params; proxy_pass http://unix:/home/myProject/myProject.sock; } } Should I have used the public address in server_name or the IP address of the virtual machine where my Django project is hosted? In addition, I also tried changing the port … -
