I can't connect to postgresql database in deployment
Hello I just want to deploy my django project in python anywhere .... and when I run the command py manage.py migrate it shows this error message django.db.utils.OperationalError: connection to server at "<Host name>" (<IP address>), port 5432 failed: Connection refused Is the server running on that host and accepting TCP/IP connections? I think that the problem in python anywhere because when I connect to the server in pgadmin using the same info in the settings.py file I don't get any error messages and you have to know that I am using neon.tech for my postgresql database DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': '<the database>', 'USER':'<User>', 'PASSWORD':'<Password>', 'HOST':'<Host>', 'PORT':5432, } } and I am sure that all information is right because I used it to connect to the server in pgadmin in my local machiene -
can we integrate websockets (ws) in our current project which only uses http.Can websockets and http can work together in one project .DJANGO CHANNELS
I created a social network site using django and my project or site was only using django with http protocols. I only have crud like features in my site but now i discovered about django channels. Django Channels allow django project to not only handle http but can also work with websockets protocol. So can we integrate websockets protocol in the website which only uses http ?. Can http and websockets protocol can work together in one project or one website ?. Can we integrate django channels in the existing django project which only uses http protocol ?. Is any website only have to use one protocol ? Hope you will help me in my journey. 😊 I tried using django channels and django in one project and it was working fine . Both http and websockets protocols was working fine but i want answer from a experience developer bcoz i don't have much knowledge about networking and protocols and i never used websockets before. -
how to do makemigrations/migrate in gnadi(python/postgresql web hebergement)
I am a python developer and new to GANDI (python/PostgreSQL web hosting). There is no document to migrate databases to their server. they have their document to deploy a Project Django but not very clear there are a lot of things missing. After taking a lot of time on the internet, I managed to deploy a Django project in their server. The site works smoothly with an SQLite database. Now I would like to make a Django Project with PostgreSQL. I have an emergency console, but I would like to work locally and then I would like to migrate the DBs to their phpPGadmin server. I just need your help to do makemigrations/migrate to thier PostgreSQL(PhpPGadmin) server. Thanks in advance. -
Different behavior between multiple nested lookups inside .filter and .exclude
What's the difference between having multiple nested lookups inside queryset.filter and queryset.exclude? For example car ratings. User can create ratings of multiple types for any car. class Car(Model): ... class Rating(Model): type = ForeignKey('RatingType') # names like engine, design, handling user = ... # user Let's try to get a list of cars without rating by user "a" and type "design". Approach 1 car_ids = Car.objects.filter( rating__user="A", rating__type__name="design" ).values_list('id',flat=True) Car.objects.exclude(id__in=car_ids) Approach 2 Car.objects.exclude( rating__user="A", rating__type__name="design" ) The Approach 1 works well to me whereas the Approach 2 looks to be excluding more cars. My suspicion is that nested lookup inside exclude does not behave like AND (for the rating), rather it behaves like OR. Is that true? If not, why these two approaches results in different querysets? -

Is good convention to define list_select_related always for all model ForeignKey fields?
I'm just doing some optimizations in my Django app and I wondered if it's a good convention when I always define list_select_related with all model ForeignKey fields in the model Admin. Now I'm not talking about ManyToMany etc where I should use prefetch_related on my own in queryset. -
Django ORM vs raw SQL - security
My django project makes use of lots and lots of database queries, some are complex and some are basic SELECT queries with no conditions or logic involved. So far I have been using the sqlite3 module to manage my database, instead of the django ORM which has worked very well. One problem or drawback I am aware of using raw SQL queries is their security flaws when compared to django's ORM, such as being viable to SQL injection attacks when passing in user input into my raw SQL queries. My question is - Is it absolutely necessary to use django's ORM for queries involving user input or can I use a general function to remove any potentially malicious characters eg (,' -, *, ;) def remove_characters(string:str): characters = ["'", ";", "-", "*"] for char in characters: if char in string: string = string.replace(char, "") return string example of vunrable query in my project username = "logan9997" password = "x' or 'x' = 'x" def check_login(self, username, password): sql = f""" SELECT * FROM App_user WHERE username = '{remove_character(username)}' AND password = '{{remove_character(password)}' """ Without the remove_characters function a hacker could gain access to someone else's account if the inputs were … -

Importing a file to a Django project - errors when running manage.py due to location of script
So, I know the source of my error, and I can fix it in a kind of hacky way, but I want to know the sort of best practices way of solving it - especially as my hacky way runs into issues when running stuff via commandline - and throws errors in my IDE. So, I have a django project, the folder tree looks like this (edited out irrelevant parts) ├── manage.py ├── simulator │ ├── angus_testing.py │ ├── events.py │ ├── parser.py │ ├── parser_test.py │ ├── patch.py │ ├── simulator.py ├── VSPOMs │ ├── settings.py │ ├── urls.py │ └── wsgi.py └── VSPOMsApp ├── admin.py ├── apps.py ├── models.py ├── tests.py ├── urls.py └── views.py When I run manage.py that is obviously running in the . directory. views.py is in the VSPOMSapp directory. If I have the following imports in views.py from ..simulator.patch import Patch from ..simulator.simulator import Simulator The IDE doesn't throw an error - and this is correct as it is searching in the parent directory for a file called patch in a folder called simulator that is in the dir above. However, when I run manage.py this causes me to get an error ImportError: attempted … -

Python Django Interaction with Third Party Backend via Client Library
I am programming a web frontend and backend with Python Django for a FinTS client (https://python-fints.readthedocs.io/en/latest/). The FinTS client library provides an API to communicate with a third party backend. The communication with the FinTS client has to be done in multiple steps: first connect then the backend asks for a TAN number the TAN number has to be provided then transactions can be fetched Basically the sequence looks like this: Sequence I am struggling with the question how I could realize this in detail with Django. I did some experiences with Django, Django Channels and Websockets, but without real success. I tried so far: A Django view provides a Django form The web client creates a websocket connection to a WebSocketConsumer The WebSocketConsumer provides its Django channel name to the web client The web client posts the form with credentials including the channel name When the form is posted, the view sends a message via a Django Channel to a BackgroundWorker inlcluding the web socket channel name The BackgroundWorker instantiates the FinTS client object and initiates the connection. The BackgroundWorker sends a message to the WebSocketConsumer asking for the TAN The WebSocketConsumer sends a web socket message to the … -

In Django, why does queryset's iterator() method reduce memory usage?
In Django, I can't understand why queryset's iterator() method reduces memory usage. Django document says like below. A QuerySet typically caches its results internally so that repeated evaluations do not result in additional queries. In contrast, iterator() will read results directly, without doing any caching at the QuerySet level (internally, the default iterator calls iterator() and caches the return value). For a QuerySet which returns a large number of objects that you only need to access once, this can result in better performance and a significant reduction in memory. In my knowledge, however, wheather iterator() method is used or not, after evaluation, the queried rows are fetched from the database at once and loaded into memory. Isn't it the same that memory proportional to the number of rows is used, wheather the queryset do caching or not? Then what is the benifit of using iterator() method, assuming evaluating the queryset only once? Is it because raw data fetched from the database and data that is cached (after instantiating) are stored in separate memory spaces? If so, I think I can understand that not performing caching using the iterator() method saves memory. -

Django DRF Djoser - change default User model to custom model which is not equal but inherited from AUTH_USER_MODEL
In django have the following custom user structure: class CinemaUser(AbstractUser): ... class CinemaAdmin(CinemaUser): .... class Cinemagoer(CinemaUser): ... Logic is that I have Cinemagoer - an ordinary user, CinemaAdmin - kind of administrator and superuser. Cinemagoer - can register themselves, CinemaAdmin is created only by superuser in settings: AUTH_USER_MODEL = CinemaUser the problem is with Djoser, a request http://localhost:8000/auth/users/ (with data in body) creates CinemaUser, because Djoser has User = get_user_model(), which means Djoser uses AUTH_USER_MODE, while I need Djoser to use Cinemagoer model to create Cinemagoer). How can I use Cinemagoer with Djoser in this case? I tried to change in Djoser/serializers directly User = CinemaUser ... just for test, it works fine, but it is definitely the wrong way. -
Django/Nginx - 403 on Static Files
I've recently uploaded a django project to an Ubuntu 22.04 DigitalOcean droplet. Nginx, gunicorn, and postgres have all been set up without a hitch, but the static files are all being 403'd. In both development and production, I never used collectstatic. The reason being, I always put all my static files in a static folder in the root of my project, so I figured I didn't have to do it. I'm not sure if collectstatic needs to be done in order for static files to be shown in production, but it seems that other people have still encountered this problem even when they've done collectstatic. My project on the server is called pyapps, and in that folder there are the static and media folders. The static folder is further broken down into css, js, and images folders. The media folder is further broken down into photos, then folder by year, month, then day, all of which correlate to the time the photos were uploaded.

I want to check if a field in an incoming request body contains only a list of predefined integers. for example, given: valid_values=[2, 3, 8] [2, 8] should pass the validation and [4, 8] or ['2', 8] should raise a validation error. First I tried using serializers.ChoiceField() but it didn't raise any validation errors for ['2', 8]. also I have tried chaining validators but apparently it's not supported in Django REST framework. so this raised a TypeError: class MySerializer(serializers.Serializer): valid_rules = [2, 3, 8] tags = serializers.ListField(child=serializers.IntegerField().ChoiceField(valid_rules)) and I didn't found anything on the documentation either.
