Django - annotate the most frequent field taken from another model linked with foreignKey
I have a model of users and a model with a survey in which users express their opinion with a vote with an integer number that identified a particular color of eyes. A srcID user describes the color of the eyes of a dstID user according to his opinion. A user can votes himself. It's possible that a user doesn't receive any votes so there isn't a tuple with dstID equal to his ID. The integer number of eyeColor rapresent a specific color, for instance: 1 => blue eyes 2 => lightblue eyes 3 => brown eyes 3 => green eyes ecc. class user: userID = models.AutoField(primary_key = True, auto_created = True, unique = True) name = models.CharField(max_length=100) class survey: srcID = models.ForeignKey(user, on_delete = models.CASCADE, related_name='hookSrc') dstID = models.ForeignKey(user, on_delete = models.CASCADE, related_name='hookDst') eyesColor= models.IntegerField() My goal is to annotate in the user model the most frequent type of eyeColor voted, so the eyesColor that other people think is the eyesColor of that user. If a user doesn't receive any votes I want to annotate 0. In case there are more than one color with the same voting frequency, if the user has voted himself (tuple with srcID = … -
Will I need to create a virtualenv every time I runserver with Django?
Currently taking CS50 Web Programming with Python and Javascript. I'm on the Week 3 Django lecture and trying to follow along but I'm running into trouble while trying to run python manage.py run server. I'm getting the "ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?" error. I'm using Windows, Django IS installed and I've reinstalled it multiple times. I've found a workaround by following the steps from https://www.youtube.com/watch?v=eJdfsrvnhTE&t=296s to set up a virtual env and can proceed after that, but in the lecture Brian doesn't need to setup a virtual env? It just loads straight through for him? Yes I have scoured through reddit, stackoverflow, youtube, and other articles online before asking this here. It's not too much trouble to do so but I'm just wondeirng why he didn't need to make a virtualenv and if I'm actually going to have to make a virtual env for every Django project going forward? Is it because things have changed with python/pip/Django? I would just find it more convenient if I could just run the run server command without having to run the extra 4 commands … -

Django serializer very slow takes 8-10 seconds
I'm trying to develop dashboard API which requires fetching data from several tables for each product, lets I have 5 products I need to query 5-6 other tables to get the data for each table. Those 5 tables are very large table in future it might even reach to 1-2M records.(they are added every minute) I used prefetch related for the backward relation - I agree query time gets reduced a lot, but serializer gets very slow no matter how many fields I have. For dashboard I need to pick the latest record related to entities I'm displaying in dashboars. My Model Class Product(): name Slug Class ProductViewedByUser()// need last user who viewed the product Users Time Similar to ProductViewedByUser I have 5-6 tables from which I need to fetch latest record. I tried Prefetch Related query time is 115 ms for 3 products and nearly 500000 cached rows. When I pass this to serializer no matter what fields are there even with one CharField- time goes to 3seconds When I have multiple fields time goes to 10 seconds I'm expecting serialization to be fast as possible. Is it good idea to create one another table for storing latest records … -

Tweepy .get_me() error when using OAuth 2.0 User Auth flow with PKCE
Trying to get an authenticated user's Twitter ID and Twitter username via the Tweepy package. With authentication through the OAuth 2.0 flow (using a Django view). I've been able to create an instance of the Tweepy pkg's Client class using the OAuth 2.0 User Context flow, but when I use the .get_me() method on it, I get an error. The error is: "Consumer key must be string or bytes, not NoneType" The error would suggest that the method wants a Consumer Key, but in this case, I initialized the Class using the OAuth 2.0 User Context flow with PKCE, which doesn't require it. I created the instance with the snippet below (in the same way it's specified in the Tweepy docs here): import tweepy oauth2_user_handler = tweepy.OAuth2UserHandler( client_id="Client ID here", redirect_uri="Callback / Redirect URI / URL here", scope=["follows.read", "users.read", "tweet.read", "offline.access"], client_secret="Client Secret here" ) access_token = oauth2_user_handler.fetch_token( "Authorization Response URL here" ) client = tweepy.Client("Access Token here") The Client object doesn't appear to be the issue, as I'm getting redirected to Twitter to authorize and redirected back via the callback as it should work. The Consumer Key is a requirement of the OAuth 1.0 User Context flow, but that's … -

Apache webserver with app using GDAL not working on windows
I am trying to deploy a django project using POSTGIS on my windows 11 PC with Apache 2.4. The web page is working as long as I am not using 'django.contrib.gis'. When I add 'django.contrib.gis' to my INSTALLED_APPS and define GDAL_LIBRARY_PATH to point to my gdal installation things stop working. Specifically, trying to access the web app ends up in infinitely loading the page. Weird enough there are no errors in the apache error log. The apache service starts fine. As far as I can see gdal install is correct as the app is working fine on the same machine with the same python environment with the django development server. Actually, I have the same issue with other python libraries that need some dlls, like opencv. So my guess is that it is a security related issue, but I do not find any clues on how to solve it. Any ideas? I tried also to grant rights to the directory where gdal is install in apache conf. But no luck. -

Updating value on django model object does not update value on related foreign key model

Tracking Django sessions with custom cookies
I am looking for a way to track the time users spend on the site. I have found the package django-tracking2, which tracks visitors by the Django session. However, my session expiry is set to 2 weeks, which makes it useless to track daily activity. My thoughts are that I can create a different cookie that expires every day, so that I can use this cookie for tracking. However, I do not quite understand how exactly I would assign a random cookie every day for users, as the Django docs does not quite have examples on this. The desired logic is: When a user opens the app, check if cookie custom_cookie is set If not, create it with a random value (probably uuid4?) The cookie should expire the same day at midnight I have come across this way of creating cookies in the middleware, however I think it will yield different random values in the request and response objects: class MyCookieProcessingMiddleware(object): # your desired cookie will be available in every django view def process_request(self, request): # will only add cookie if request does not have it already if not request.COOKIES.get('custom_cookie'): request.COOKIES['custom_cookie'] = uuid.uuid4() # your desired cookie will be available … -

How can I set Django views depending on api source?

django DRF Performance problems with logic with multiple conditions
The shopping cart model stores cart items for both guest users and registered users. I provide the guest user a unique key using uuid and save it to the cookie. The situation that I want is to link the cart items that is included in the guest user's status to the login user's cart. So I wrote logic considering 3 situations. When you are a guest user, press the shopping cart button to create a cart model. If you fill up the shopping cart before logging in, remove the unique key of the shopping cart model and update it with your user information. If you press the shopping cart button after logging in immediately, create a cart immediately. Does configuring logic under these three conditions adversely affect performance? Is it common to use multiple conditions like this? Is it overloading the server? Help me improve my logic. thanks @api_view(['POST']) def addToCart(request): user = request.user data = request.data guest_id = request.COOKIE.get('guest_user') #if anonymous user puts item in the cart if not request.user.is_authenticated: cart = Cart.objects.create( guest_id = guest_id ) CartItems.objects.create( cart = cart, product = data['product_id'], product_option = data['product_option'], qty = data['qty'] ) serializer = CartSerializer(cart, many=False) return Response(serializer.data) #if guest_user … -
