Django, passing get query has a value to filter query, calls get query twice
I have get query which is passed as a value in filter query ,when running the code get query is called twice. #get query employee = Employee.objects.get( user=self.request.user.email, project=self.request.org_id) #filter query LeaveApproval.objects.filter(approver=employee) #dbCallLog SELECT ••• FROM "leavetracker_employee" WHERE ("leavetracker_employee"."project_id" = 'f5b10d49-9056-4faa-b95a-251f998a724f'::uuid AND "leavetracker_employee"."user_id" ='rajini@gmail.com') LIMIT 21 2 similar queries.

Tailwind Dynamic Colour Based on Page/URL
I was hoping someone new how I could dynamically set text/bg colours based on the current page I'm on?

Django views.py code running automatically whenever I reload the server
I have logs which are uploaded and inserted into MySQL table from CSV files using upload_log endpoint in views.py of a Django app. I also have another views.py in a different sub-app (Django as well) that parses the existing data from the logs table and splits it in different rows according to conditions. The problem is the parsing happens whenever I reload the server which creates duplicates besides the fact that it is not my intention to have it like this. I need to have it so that whenever data is uploaded (post is triggered), it runs the function on that uploaded data to parse the logs. Edit (clarification): It doesn't execute when I do py manage.py runserver - But it executes after I run the runserver command and CTRL + S inside the file to reload the server. I would appreciate it if someone guides me through this. Here's the views.py of that task (Logs app): from rest_framework import viewsets from rest_framework.decorators import action from api.packets.models import Fields from .models import LogsParsed from api.logs.models import Logs from .serializers import LogsParsedSerializer class getLogs(viewsets.ModelViewSet): serializer_class = LogsParsedSerializer queryset = LogsParsed.objects.all() parsedLogs=[] for log in Logs.objects.all(): fields = Fields.objects.filter(pac_id=log.message_id_decimal) binaryTest=log.data_binary for field … -

Python: Display either Video or Image File, but it shows both
I have been working on a social media website where you can upload images and videos and follow other users. I managed to upload and display uploaded files to the website.

Django boto3 with s3 not working in production
So I am currently trying to enable large file uploads for my site www.theraplounge.co/ the only problem is I’m using boto3 to upload directly to s3 with https://justdjango.com/blog/how-to-upload-large-files as a guide. The good thing is large files get uploaded when I’m on development server. When I launch code to production server on heroku large files don’t upload anymore. I don’t think code would work locally but not in production which leads me to think the problem may be heroku 30s timeouts although I’m not sure. Anyone got a glue or a hint at what’s going on? -

Wagtail-2fa token doesn't work when setting up 2fa after new admin user registration
New users can't seem to set up 2fa--token always fails at set up with wagtail-2fa. Background: I set up a wagtail site a few months ago with Wagtail-2fa (which is based on django-otp). When I first set up an admin user with 2fa, the token works fine. That admin login has no problems using 2fa. When I try to set up new users, I can register the user, but when the user logs in for the first time, it requires 2fa set up (which is the desired behavior) but the token always fails. I've tried Google Authenticator, Symantec VIP, and Duo Mobile. None of them work for new users. Wagtail-2fa uses TOTP so I checked the time on the device and on the server and they appear to match at least to the minute. I've tried the same process on my localhost, staging, and production (the latter two on heroku), and none of them work (but the original admin with 2fa works). My main hypothesis now is that something broke with wagtail-2fa when I upgraded several packages: django 3.1.11 --> 4.0.5 wagtail 2.15.1 --> 3.0.1 It could be that wagtail-2fa doesn't support wagtail 3.0.1 or django 4.0.5.

I save multiple copies of videos with different resolutions, and when users change the quality, I change the displayed video, but how can I dynamically change the resolution and not store many copies? -
choose one value multiple time in many to many field of Django
i'm creating a Ecommerce website & i have a order item model which has many to many relationship with product model so customer can add products to their order. everything is okay with my system but the customer can't order one product twice or more since Many to many field choose an option once! how can i add one value twice in a many to many field?? also if you think there's a better way rather than using this system & many to many field, you can suggest! #my_views_py from django.db import models from django.contrib.auth.models import User class Customer(models.Model): user = models.OneToOneField(User,null=True,blank=True,on_delete=models.SET_NULL) name = models.CharField(max_length=100,null=True) email = models.CharField(max_length=100,null=True) def __str__(self): return self.name or str(self.id) class Product(models.Model): title = models.CharField(max_length=200) price = models.FloatField() image = models.ImageField(upload_to='static/images') def __str__(self): return self.title class Order(models.Model): customer = models.ForeignKey(Customer,on_delete=models.SET_NULL,blank=True,null=True) date = models.DateField(auto_now_add=True,blank=True) complete = models.BooleanField(default=False,null=True,blank=False) transaction_id = models.CharField(max_length=200,null=True,blank=True) def __str__(self): return str(self.id) class OrderItem(models.Model): product = models.ManyToManyField(Product,blank=True) order = models.ForeignKey(Order,on_delete=models.SET_NULL,null=True,blank=True) date = models.DateField(auto_now_add=True) def __str__(self): return str(self.order)
