Django REST Framework permission_classes ModelViewSet
How do I create a permission, that only allows the user to be able to read, if they are logged in. If they are not logged in, they can not do anything. I feel like this is probably very easy, but I can't seem to find the answer. This is my views.py file: class MovieViewSet(viewsets.ModelViewSet): queryset = Movie.objects.all() serializer_class = MovieSerializer permission_classes = (permissions.IsAuthenticatedOrReadOnly, ) I know IsAuthenticatedOrReadOnly allows the User to read, but I don't even want that. -

Remove remaining celery tasks when concurrency is set to 1?
I have a Django application running with Docker, I'm looking for a way to terminate the remaining celery tasks when the concurrency is set to 1. This is my urls.py file from django.urls import path from . import views urlpatterns = [ path('start-process', views.start_process), path('terminate-process', views.terminate_process), ] This is my views.py file from .tasks import add_task, remove_tasks def start_process(request): add_task.delay() return HttpResponse('Task Started') def terminate_process(request): remove_tasks.delay() return HttpResponse('All remaining tasks will be removed') This is my tasks.py file from celery import shared_task from my_app.celery import app from time import sleep @shared_task def add_task(): sleep(50) return 'task completed' @shared_task def remove_tasks(): app.control.purge() return 'All tasks removed' This does not work as expected because the concurrency is set the 1. I have started the celery worker with the following command celery -A my_app worker --concurrency=1 --loglevel=info Is there any way I can remove the remaining tasks when the terminate-process url is called? -

Django Image Resizing Before Upload
Currently, If I upload an image, It shrinks the image size then overwrites the file inside AWS s3 storage Media file and name it to the the file's original name For example: If i upload a 1MB size image called AA.png, It shrinks the size to 50KB, Then in AWS S3 Media file you would find the shrinked image named AA.png I want: File extension to always be .jpg, Eg: User uploads .png but stored as .jpg in AWS S3 Media Give each image a unique name generated by random numbers or strings If I change to storage.save("{random_number}.jpg", memfile), then the above problems could be solved, But it creates 2 Images in the S3 Media file, Eg: If a user uploads 1mb AA.png, Then results in S3 Media would be: some_random_number.jpg(50kb), AA.png(1MB, untouched original image), If I am correct, The image files in S3 are being overwritten if it has the same name, Is there a way to shrink the image in Django before it reaches S3 Media file and prevent the original image from being stored in the first place?

Problems deploying Django on a web server hosting multiple sites
Currently I am working on migrationg a Django site (app) to a hosting service, folder structure is as follows: /home/user /public_html /example.com /example.ee - wordpress site, needs to keep working /example.fi - where I am trying to deploy the django app When I try to install a Python app from cPanel, and set up everything to work for django application, wordpress site and all others return a 500 internal server error, how could I deploy django only for one domain without affecting other domains at all... also a problem is if I set ALLOWED_HOSTS=['*'] it does load the other pages but it loads them wrong (showing a wrong page as the home page etc.) I have searched online for a day now and I can't seem to find the answer, cPanel installs the python virtualenv into the user home directory and not in the public_html folder, where I would like it to run. and I want it to only affect the domain it is a part of.

Django template VS Angular/React/Vue - Perforamance
Since i am confused to either combine django and any javascript framework or use django templates. I would like to know to following queries, How will be the performance will effect if i combine both of them together instead of django templates? Why people prefer to combine 2 frameworks together and will they prefer for huge projects like ERP and why? Since connecting and fetching data from database like MySQL and NoSQL have major impact on performance, Does REST API (or any other way) will solve the problem? Because django templates providing inbuit functions to display the data (Suppose we have to add loop in front end and backend) I hope you will consider seconds of time for the performance monitoring. Why not bootstrap? Note : I am new to front end frameworks. -
Does Google "validate" forgotten password links? [closed]
I am working on a web app using Django (hosted on Heroku). I was testing the password reset functionality and it all worked as expected. However, I found in the web logs that after I had accessed the generated link that the exact same URL was requested 14 minutes later by a different IP address. The link had expired so the response was a 400 code. For reference, the password reset link looks like this and was sent to my gmail account: https://www.example.com/password_reset/[uidb64]/[token]/ I looked up the IP address and it shows the following host name: [town]-google-cdn-01.network.[UK-ISP].net There is no other unusual traffic to the site and my email account is secure. The only thing I can think of would be if Google were to check unidentified password reset links for phishing threats, but is that actually a thing? Is there any other way that the URL could be found? -

Get unique outputs from combining more than one Django filters
So, I am trying to create a search engine on my website where the user enters a query and I display those results where the query exists inside the product name or description. My product model is as follows:- '''Product model to store the details of all the products''' class Product(models.Model): # Define the fields of the product model name = models.CharField(max_length=100) price = models.IntegerField(default=0) quantity = models.IntegerField(default=0) description = models.CharField(max_length=200, default='', null=True, blank=True) image = models.ImageField(upload_to='uploads/images/products') category = models.ForeignKey(Category, on_delete=models.CASCADE, default=1) # Foriegn key with Category Model store = models.ForeignKey(Store, on_delete=models.CASCADE, default=1) Now, I have created a search filter where I filter by name and then by description and then combine the results to return a queryset. The issue is that sometimes the query can be found in names and in descriptions so I get repeated entries like this My filtering code is mentioned below:- names = queryset.filter(name__icontains=search_query) descriptions = queryset.filter(description__icontains=search_query) queryset = list(chain(names, descriptions)) return Response(ProductSerializer(queryset, many = True).data) I want to be able to only get one result since it's the same product. Is there a way I can only save the distinct results in query set. I made a loop which checks the results in descriptions … -
Python+Django : Bug in code looking for a 2nd insight
I have a function with the following code: if request.method == 'POST': company_id = request.POST.get('company_id') choice_list = request.POST.getlist('info[]') response = read_csv_lines(choice_list,company_id) print(response) choice list contains numbers selected in a list. For example [2,3] and the ID of a dropdown box This one goes to the following function (read_csv_lines) def read_csv_lines(my_list,company_id): test_file = './upload.csv' company = Company.objects.get(id=company_id) with open(test_file) as csv_file: file_reader = list(csv.reader(csv_file, delimiter=';')) for i in my_list: i = int(i) deviceinf = file_reader[i] status = add_device(deviceinf,company.auth_token,company.company_name) I get the info from the company cause i need these to make an api call in a seperate function i open the file read every line but all lines in a list and for the value i I read the line in the list of read lines. And pass this trough to my API call. What happens next is the bug. When i launch a POST the following thing happens: It enters the read_csv_lines. jumps right back out and print as response "None" but the other calls keep on going and the api call in the background executes Could someone look into this as a 2nd opinion ? -

ORDER BY not allowed in subqueries of compound statements; union queryset
I'm trying to create a listing page of all the questions posted that share the same type of tags a single user has used in their own questions. In other words, if a User has only posted questions about Python and OOP, they would only see questions that shared either one or both of those tags. Upon trying to implement this, I tried to use the .union() queryset to add the different filtered querysets together. However the following error is raised: ORDER BY not allowed in subqueries of compound statements. I found a similar issue raised here and it mentions how the method may be incompatible with SQLite which is the database I'm using: error "ORDER BY not allowed in subqueries of compound statements".
