Grey box rendered in place of icon on Google Maps
I'm using the Google Maps API in my Django project to display the current users location and this is my first time using maps. The map loads fine, but there's a grey box in place of where the map marker should be(Just over the Au in Australia): // Initialize and add the map function initMap() { // The location of Uluru const uluru = { lat: -25.344, lng: 131.031 }; // The map, centered at Uluru const map = new google.maps.Map(document.getElementById("map"), { zoom: 4, center: uluru, }); // The marker, positioned at Uluru const marker = new google.maps.Marker({ position: uluru, map: map, }); } window.initMap = initMap; I've customized the icon to display a different image and only the size of the grey box changed, there are no errors in the console. Any help would be appreciated! -

Slow loading Django Admin change/add
The Loading time is too much for this particular model in admin panel.I know it is because I have too many values in Foreign Fields (field with 20k+ records each) which takes too much time to load on client side.

How to ensure that a custom field may be used when creating an instance but is not included when updating?
I have a serializer for a User model with custom fields password_1 and password_2 configured with write_only = True so they are not displayed with GET but required with POST when creating a new model, which is perfectly fine. My problem is the PUT method, because when I want to update a model the fields are still required. How can I configure the serializer or the view to make these two fields optional with PUT ? I test my code with the browsable API and the PATCH method, although supported, isn't proposed when updating a model. This is what I've tried: first I updated the put method of the view by adding partial_update, but I couldn't get the expected result, probably because they are custom fields. views.py @permission_classes([IsAuthenticated]) class ManagerDetailsView(RetrieveUpdateAPIView): serializer_class = ManagerSerializer lookup_url_kwarg = "pk" def get_object(self): pk = self.kwargs.get(self.lookup_url_kwarg) obj = get_manager(pk) return obj def get_permissions(self): if self.request.method == 'PUT': self.permission_classes = [HasChangeManagerObjectPermission | HasTeamLeadPermission] return super(self.__class__, self).get_permissions() def put(self, request, *args, **kwargs): return self.partial_update(request, *args, **kwargs) Then I undo the previous try and modified the validate method of the serializer by setting kwargs["partial"] to True but it has no effect. serializers.py class ManagerSerializer(serializers.ModelSerializer): password1 = serializers.CharField(write_only=True) password2 … -
Can't get NGINX to read socket created by GUNICORN via SUPERVISORD (permission error)
I'm trying to run Django on AWS/Ubuntu using NGINX/Gunicorn (via supervisord) My Nginx logs keeps throwing a permission error when trying to access app.sock. "app.sock" is created by gunicorn, and gunicorn is run by supervisord, and supervisord is a nightmare. ps aux | grep nginx root 63435 0.0 0.1 55200 1692 ?

And here is my supervisord config file [program:gunicorn] directory=/home/ubuntu/www command=/usr/local/bin/gunicorn --workers 3 --bind unix:/home/ubuntu/www/app.sock matched.wsgi:application user=www-data autostart=true autorestart=true stderr_logfile=/logs/gunicorn.err.log stdout_logfile=/logs/gunicorn.out.log In my config file, I've attempted to tell supervisor to run my gunicorn command AS www-data, but its still creating app.sock as root. It seems like the "user" parameter does not do anything at all. The only solution I see to this ridiculous problem is to run Nginx as root, which I know is a bad idea. I've searched almost every discussion on the web and I cannot … -

csv file stored in Django members directory loaded as directory instead of csv file
I am working in a Django app in a directory myworld. In this directory, I have a members directory with a templates directory with an html file myfirst.html.

Deploying Django app to Elastic Beanstalk Docker platform
Im'm trying to deploy a django app to single docker container platform on EB version Docker running on 64bit Amazon Linux 2/3.5.2.

Django Soak Testing Bulk Request at once
I want to test whether Django can handle heavy load requests at once continuously. How to conduct this scenario? using tests?. Eg: 300 Read requests 300 Write requests within 1 sec. You can take any basic ORM query like User.objects.get(id=`some id) for 1 request and take this as 300 different read requests. Same for write requests as well but change any field of your choice. Later check if that works for at-least 10 sec. You can think of this scenario as multiple concurrent users using the Django app. -
Annotate value to a many to many field in django

I was doing something like this: a=A.objects.filter(id=2).first() a.users.all().annotate(games_played='some condition here') but this statement is returning a queryset of User model. Is it possible to annotate data to a many to many field of an instance and still have an object of model A so that I can do this; a.users.all()[0].games_played
