Change form input from text value to model instance in django
I want to create Aviz entry using AJAX form. In the form the input material has a jquery ui function autocomplete, that gets all the material names from the Material Model.

How to create a base serializer to custom generate file field urls
I'm using Django's django-private-storage When an api is created using drf, in the case of a general file field, the url starts with http:// in local and https:// in dev and prod. But for privateFileField it starts with http:// everywhere. Therefore, I want to create a BaseSerializer and create a custom url when the field is a privateFileField. And I want the model serializer with privateFileField to inherit from that serializer. What should I do? I could use get_value() function, but I don't want to implement that function in every model serializer with privateFileField. I want to reduce repetition. Also, the settings that change http:// to https:// are already applied. Only privateFileField is a problem. -

Author page in django migrations and questions
I want to make a website for eBooks with a page that has all the books published by one of the authors. The problem is that I have no idea how to do that. I will mention that I am a beginner. I tried this int the model file class Author(models.Model): author = models.TextField() class Product(models.Model): … author=models.ForeignKey(Author,on_delete=models.CASCADE) The result in the terminal was: File "/home/user/petnet/petnet-env/lib/python3.10/site-packages/django/db/backends/sqlite3/base.py", line 264, in check_constraints raise IntegrityError( django.db.utils.IntegrityError: The row in table 'store_product' with primary key '2' has an invalid foreign key: store_product.author_id contains a value 'anonim' that does not have a corresponding value in store_author.id. I think this is caused by the act that I made the author field later and there were already authors fields from before, but then, when I tried to revert back to what I had before doing this, I got some errors regarding migrations. Also the views were: def author_detail(request, slug): author = get_object_or_404(Author, slug=slug) products = author.products.filter(status=Product.ACTIVE) return render(request, 'store/author_detail.html', { 'author':author, 'products':products }) But I am also curious if there is a chance I could use only this for models so I could use the form for adding a product in a much easier way. class Product(models.Model): … -
Django: Problems passing a list and the results of the list treated by a function as two separate variables to the template
I'm trying to make CV website which has a sudoku generator and solver. The generator and solver are two separate functions in the functions.py file imported into the views.py file. My sudokus are stored in a list of 9 lists of 9 ints. from views.py: from functions import * def sudoku(request): grid = make_sudoku() # generates unsolved sudoku list solved = solve(grid) # generates solved list of unsolved list fed in. count = [i for i in range(9)] context = { 'grid': grid, 'solved': solved, 'count': count } return render(request, 'main/sudoku.html', context) if I print grid, I get an unsolved sudoku list. If I print solved, I get a the same list which has been solved. Everything works dandy up until that point, but if I go to sudoku.html and type {{ grid }}, I get a solved sudoku list. As the tree said to the lumberjack, I'm STUMPED! I'm completely baffled as to why this might happen because at no point in sudoku.html do I refer to grid or solved outside of passing them on to sudoku.js which actually makes the puzzle. -
I can't connect to postgresql database in deployment

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)

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.

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.

And I got the following error : Can't add file /var/lib/docker/overlay2/8a4e2447c4fc77a20c1f075fc5d887520fe22dd6ee559cfd480287e4914a1c5c/diff/run/apache2/wsgi.24.0.1.sock to tar: archive/tar: sockets not supported Some informations on my env : . ├── .dockerignore ├── .env ├── .git ├── .gitignore ├── .gitlab-ci.yml ├── Dockerfile ├── Project ├── README.md ├── docker-entrypoint.sh ├── requirements.txt ├── site-config.conf ├── user └── utils Dockerfile : FROM debian:bullseye-slim RUN apt-get update RUN apt-get install -y apt-utils dialog RUN apt-get install -y nano curl apache2 apache2-utils RUN apt-get -y install python3 libapache2-mod-wsgi-py3 python3-venv RUN ln /usr/bin/python3 /usr/bin/python RUN apt-get -y install python3-pip RUN pip install --upgrade pip ENV PYTHONUNBUFFERED 1 RUN mkdir /code/ WORKDIR /code/ COPY requirements.txt /code RUN python -m venv .env RUN pip install -r requirements.txt COPY . /code/ ENV F_FROM_DOCKER=True RUN chmod 775 docker-entrypoint.sh ADD ./site-config.conf /etc/apache2/sites-available/mpn.conf RUN a2dissite 000-default RUN a2ensite mpn RUN service apache2 start EXPOSE 80 3500 CMD ["./docker-entrypoint.sh"] It's a Django project using apache.

How can I send swift json to django server?
Swift code: static func send(url: URL, data: Data) async { var request = URLRequest(url: url) request.httpMethod = "POST" let json: [String: Any] = [ "order_details": ["meal_id":"6", "quantity":"1"], "restaurant_id": "1", "access_token": "FUJMNpU77OyuLiohOl5wzRQkGpHleV", "address": "13" ] let jsonData = try? JSONSerialization.data(withJSONObject: json) request.httpBody = jsonData print(String(data: jsonData ?? Data(), encoding: .utf8)) do { let (_, response) = try await URLSession.shared.data(for: request) guard let statusCode = (response as? HTTPURLResponse)?.statusCode, 200..<300 ~= statusCode else { throw URLError(.badURL) } } catch { print(error) } } Print: Optional("{\"address\":\"13\",\"order_details\":{\"quantity\":\"1\",\"meal_id\":\"6\"},\"restaurant_id\":\"1\",\"access_token\":\"FUJMNpU77OyuLiohOl5wzRQkGpHleV\"}") JSON looks normal. BUT in my django server I get this: if request.method == "POST": print(request.POST) Print: <QueryDict: {'{"address":"13","order_details":{"quantity":"1","meal_id":"6"},"restaurant_id":"1","access_token":"FUJMNpU77OyuLiohOl5wzRQkGpHleV"}': ['']}> i.e. my request becomes a key I tried to compose the request in different ways, I used JSONEncoder and JSONSerializer but nothing happened
