I'm very new to programming. I would like to pass data from html input to update view and then save it to my database. Tried to search for it but with no luck.

How to Join Subqueries in Django ORM
I'm a beginner Django and I have been stuck on the following problem for a while. The basic thing I would like to achieve is that when client makes a GET list api request with a time period parameter (say 3 months) then the server would return an aggregation of the current 3 months data and also show an extra field comparing the difference with previous 3 months. I have models as: class NTA(models.Model): nta_code = models.CharField(max_length=30, unique=True) ... class NoiseComplaints(models.Model): complaint_id = models.IntegerField(unique=True) created_date = models.DateTimeField() nta = models.ForeignKey( NTA, on_delete=models.CASCADE, to_field='nta_code') ... The sample output I would like to get is something like: [ { "id": 1, "nta_code": "New York", "noise_count_current": 30, # this would be current 3m count of NoiseData "noise_count_prev": 20, # this would be prev 3m count of NoiseData "noise_count_diff": 10, # this would be prev 3m count of NoiseData } ... The raw SQL query (in Postgres) is quite simple as below but I'm really struggling on how to make this work in Django.

Multiple container app: execute container from another container
I have a multi container Django app. One Container is the database, another one the main webapp with Django installed for handling the front- and backend. I want to add a third container which provides the main functionality/tool we want to offer via the webapp. It has some complex dependencies, which is why I would like to have it as a seperate container as well. It's functionality is wrapped as a CLI tool and currently we build the image and run it as needed passing the arguments for the CLI tool.

Verifying AzureAD access token with Django-REST-framework
Before anything I would like to warn you about my extremely limited knowledge on the subject. Now that you've been warned, what I need to ask is how can I verify and azureAD access token with Django/django-rest-framework. I have a app that I need to sing in to with azureAD, which means I need to get an access token from azureAD, and thankfully this is will be done on the frontend side with Angular what I need to do is verify that token on the backend side with django/django-rest-framework and I have no idea where to start from, can anyone suggest a way to do this or send me in the right direction ?

Django/Flask : Rewritting an Flask Azure B2C authentication in Django, issue with the scope

Why homebrew installs everything in /opt/homebrew/Cellar, while my python project looks for everything in /usr/local
I'm new to macos using Monterey on an M2 macbook Air, and having a hard time satisfying dependencies for a django project. To make it clean and simple, I've build python 3.8 from source, --with-openssl=/also/built/from/source, created a bin/python -m venv django, went source ./django/bin/activate, and installed the project requirements.txt. After running a project, i keep encountering missing library errors, like '/usr/local/lib/libssl.1.1.dylib' (no such file) '/usr/local/lib/libcairo.2.dylib' (no such file) '/usr/local/lib/libffi.8.dylib' (no such file) etc. Even though in the case of libssl for example, i would have expected python to know the location of the custom built openssl, i've went ahead and installed these system dependencies with brew install openssl@1.1 cairo libffi etc. but the errors persisted until i linked (ln -s) each library from /opt/homebrew/Cellar/libffi/3.4.2/lib/libffi.8.dylib to /usr/local/lib/libffi.8.dylib. Why is all this happening? Why is homebrew not populating a static library path? -

Django ORM query optimisation with multiple joins
In my app, I can describe an Entity using different Protocols, with each Protocol being a collection of various Traits, and each Trait allows two or more Classes. So, a Description is a collection of Expressions.

Tall Trait 2: Weight Available Classes: a. Light b. Medium c. Heavy John's Description: Expression 1: c. Tall, Expression 2: b. Medium My model specification (barebone essentials for simplicity): class Protocol(models.Model): name = models.CharField() class Trait(models.Model): """ Stores the Traits.

How do I import a Json file into a django database whilst maintaining object references
I have a C# desktop app and a django webapp that share a set of common class/model types. The C# app is exporting json files containing instances of these models, and I am trying to import these into the django database. The complication is that the parent model contained within the json file has properties that may reference the same sub-model in multiple places. For example, the json file looks something like this: { "$id": "1", "SubModels": { "$id": "2", "$values": [ { "$id": "3", "name": "Dave", "value": "123" }, { "$id": "4", "name": "John", "value": "42" } ] }, "PreferredSubModel: { "$ref": "4" } } Which was created using the using System.Text.Json.Serialization C# library with the ReferenceHandler = ReferenceHandler.Preserve serialisation option. In django, I've converted the json file into a dictionary using model_dictionary = JSONParser().parse(json_file). Are there any existing functions (in the django Python environment) that can handle this $id/$ref system to maintain class instances, or do I need to code my own deserializer? If the latter, does anyone have any suggestions for the best way to handle it? I'm new to django and json files, so hopefully I've just been googling the wrong terms and something exists... -
