"Optimizing Django Form/Table Reload for Improved Performance and Minimizing Page Reloads"
1-I'm encountering challenges with page reloading and performance optimization in my Django project. The primary issues involve the reload behavior of a form or table, where the entire page refreshes upon submission. i want only table elements or data will refresh or reload not the whole page will reload.. 2- the second issue is that it is taking too much time to reload or fetch or run queries can we make it faster.. this is my views.py- def Home(request): # Get the filtered data using RocCharge model from filters.py myfilter = Orderfilter(request.GET, queryset=RocCharge.objects.all().select_related('RocCharge')) # Logic for clearing all filter buttons if request.method == 'GET' and 'remove_filter' in request.GET: filter_name = request.GET['remove_filter'] myfilter.form[filter_name].initial = None elif 'remove_all_filters' in request.GET: for filter_name in myfilter.form.fields: myfilter.form[filter_name].initial = None # Showing or getting applied filters data combined_data = myfilter.qs.values( 'srn_no', 'charge_id', 'charge_holder_name', 'date_of_creation', 'date_of_modification', 'date_of_satisfaction', 'amount', 'address', 'existing_old', 'cin__state', 'cin__city', 'cin__company_name', 'cin__company_cin', 'cin__sector', 'cin__industry', ) from_date = request.GET.get('fromdate') to_date = request.GET.get('Todate') if from_date and to_date: combined_data = combined_data.filter(date_of_creation__gte=from_date, date_of_creation__lte=to_date) # download data logic/func.................................. if 'download_xlsx' in request.GET: filtered_data = myfilter.qs.values( 'charge_holder_name', 'date_of_creation', 'date_of_modification', 'date_of_satisfaction', 'amount', 'existing_old', 'cin__state', 'cin__city', 'cin__company_name', 'cin__company_cin', 'cin__sector', 'cin__industry' ) # Convert the filtered data to a DataFrame df = pd.DataFrame.from_records(filtered_data) … -

Converting Boolean value from DB to Bootstrap switch input - Django
I have a boolean field in the database - emails_allowed. This is reflected in the user profile page as a bootstrap 5 switch input To represent the current value in the database I am using the template language in the following manner - <input class="form-check-input" style="margin-left: -1.5em;" type="checkbox" id="email-allowed" {{ profile.email_allowed|yesno:"checked,unchecked" }}> I was expected the template language to merely output checked or unchecked as a string. Instead it is creating a HTML attribute called checked or unchecked as shown below - <input class="form-check-input" style="margin-left: -1.5em;" type="checkbox" id="email-allowed" checked=""> As a result, I am unable to change the state of the switch as it is permanently either checked or unchecked. Has anyone come across this issue? Any suggestions on how to solve this is greatly appreciated. Thanks in advance -

I want to know the hashed version of the password that is generated when using the user.set_password(pasword) method in Django and print that password
I want to know the hashed version of the password that is generated when using the user.set_password(password) method in Django and how to print that password? I'm trying to understand how Django's user.set_password(password) method works. Specifically, I'm interested in the generated hashed password, which is a secure representation of the plain text password. Can anyone explain how this method stores the password securely and how the hashed password can be used for authentication? code I am using: password = sellerForm.data['password'] user = User.objects.create(username=email,email=email,first_name=first_name,last_name=last_name,is_superuser=0,is_staff=0,is_active=1) user.set_password(password) user.save() See the actual hashed value of the password printed to the console or output. Understand how Django stores passwords securely using this method. Learn how the hashed password is used for authentication purposes. -

Extract Individual URL Request Counts
I have a Django app running with NGINX as a reverse proxy.

For instance, if I have two URLs, /job1 and /job2, I want to see the following metrics: number_of_requests{path:/job1} 20; number_of_requests{path:/job2} 30; Is there a way to achieve this?

How to give a user an authentication token with DRF to use in APIs based only off their username found in headers (no password)
To reach this token generating API on the web the user will have to first authenticate with Oauth2 with their company username/password. This username is now in the header as USERINFO-cn and I can access it with user = request.META['USERINFO-cn'] I want to take the username and assign that user a unique token. I've tried following the example in the django-rest-framework documentation on generating tokens with a customized version of obtain_auth_token. This code gives an error since Token.objects.get_or_create(user=user) is obviously expecting more than just a username. from rest_framework.authtoken.views import ObtainAuthToken from rest_framework.authtoken.models import Token from rest_framework.response import Response class CustomAuthToken(ObtainAuthToken): def get(self, request, *args, **kwargs): user = request.META['USERINFO-cn'] token, created = Token.objects.get_or_create(user=user) return Response({ 'token': token.key, 'user': user }) I know this method may be confusing but basically I want internal users at my company to be able to use other APIs without exposing their password (just a token) but I will at least be able to determine which users are calling APIs based off the token. -

Unable to Run Python HTTP Server on Port 8001 - Need Help in Creating a Minimal, Reproducible Example
Question: I'm encountering an issue while trying to run a Python HTTP server on port 8001 using the command python -m http.server 8001. The server starts, but I'm unable to access it. I've ruled out common problems like port availability and firewall settings. Here's what I've tried: Ensured that port 8001 is not in use by another process. Checked firewall settings to allow traffic on port 8001. Double-checked network configuration. Despite these checks, the issue persists. I'd like to seek help on Stack Overflow, and I want to follow the guidelines for creating a minimal, reproducible example. Can someone guide me on how to structure my question effectively? I want to provide a clear and concise example that others can easily understand and use to help me troubleshoot this problem. Thanks in advance! -
