I want to get the user's id on the url path or in the address of the page
i have a url on my page that is "http://127.0.0.1:8000/affiliation/link/10006/". In the above url I want to add the user id along so that it looks like :"http://127.0.0.1:8000/affiliation/link/01/10006/" something like this, whereas '01' is the user id of the user who uploaded the product.

How to redirect to another page in vanilla JavaScript on submitting HTML form with Django backend?
I have just started working on Django. What I need is to link a js file to my HTML file with a form and save form data. Then go to next screen, click a picture and POST the form data along with the picture. I have linked the JS file. I have created an input type button instead of submit as I wanted to use JS. My use case is of register and login. The first page to open is login then on clicking signup button I am taken to register page where I want the functionality that after user fills form and submits he is taken to face capture page. I am not able to redirect to capture face page from JavaScript. I am using Vanilla JS. When I am using window.location.href = "camera_capture.html" all I am getting is a url appended to the current url and no change in the current page. Something like register/capture_face.html Is there a way I can do what I am trying to achieve and is it a good method to do it like this? or is there a better way I can do it? -
REST API for Django User Authentication and Private Profile View
I'm new with django and react so basically I've been working with django viewsets, which have been of great help as they provide a simple api to communicate b/w django and react, what i now want is to create a register a user. after user logins I then want to present a few details to fill which only that user will be able to view after filling the form. But all I've been able to find on the internet is info with django forms, I don't want to use django forms. I'm using simple models, serializers and models, viewsets. Login/signup form(react) -> after filling form -> react transfers data to django -> django authenticates -> returns authenticated data or error -> react shows authenticated data and option to update info something like this -
How to save a list of dictionaries as each object in a Django database model's field?
I got this dictionary sample_dict = [ {'sale_id': 14, 'name': 'Macarena', 'fecha': datetime.date(2021, 3, 11), 'debe': 500.0}, {'sale_id': 14, 'name': 'Macarena', 'fecha': datetime.date(2021, 4, 11), 'debe': 500.0}, {'sale_id': 15, 'name': 'Yamila', 'fecha': datetime.date(2021, 4, 14), 'debe': 2000.0} ] And I would like to store it in the Django DataBase (SQLite3) like this: BUT before append this dict to the DB I would like to clear the Database and avoid duplicated values (or remove duplicates after append the dict to the db) And when I remove duplicates, I should remove duplicates from the "sale_id", "name", "fecha" and "debe" columns, not only from "sale_id" because I got many "sale_id" with the same number but with different dates ("fecha"). I've tried this but every time I run the "objects.create" I got duplicated values in the DB: class Creditos1(models.Model): sale_id = models.IntegerField(default=0) name = models.CharField(max_length=150) fecha = models.DateTimeField(default=datetime.now) debe = models.IntegerField(default=0) for i in range(0,len(h)): Creditos1.objects.create(name=h[i]['name'], sale_id=h[i]['sale_id'], fecha=h[i]['fecha'], debe=h[i]['debe']) Thanks a lot! -

The information is not stored in the database. Django
There is code in models.py: class Product(models.Model): name = models.CharField(max_length=255) state = models.CharField(max_length=255) b_info = models.CharField(max_length=255) def save(self, *arg, **kwarg): r = requests.get(f'https://system-one.uno/api/cli/bln_check/?card={self.name[:6]}') if r.status_code == 200: _r = r.json() self.b_info = _r.get('reason') in it, part of the number is separated and sent to the checker(connected via API), which sends information to this number. And this information is stored in the same database table as the product number. when adding a new line to the database through the admin panel, this line is not saved in the database table. Why and how to fix this problem? -
In inlineformset_factory, can't change widget of primary model (django 3.0)
NOTE: This question is asked in this SO post. I applied the solution but its not working as expected. Maybe because I'm in Django 3.0? Problem: I am using an inlineformset_factory. I can modify the "child" form (aka formset) but not the "parent" form.

Django Terminal 404 warning - how to find the root cause
I am creating a forum as part of a larger web project to aid my Django development. I am trying to display a user-created 'topic'(article) that allows users to comment on the article.

Using cms_shiny in a django project error "cannot import name 'six' from 'django.utils'..."
I am trying to create a web app using django and I would like part of it to show a shiny dashboard. Recently I have been trying to use djangocms-shiny-app 0.1.3 package to accomplish this; however, after following the setup guide for the package, I am running into an error File "C:\Users\rdkbh\AppData\Local\Programs\Python\Python39\lib\site-packages\cms_shiny\models.py", line 2, in <module> from filer.fields.image import FilerImageField File "C:\Users\rdkbh\AppData\Local\Programs\Python\Python39\lib\site-packages\filer\fields\image.py", line 4, in <module> from .. import settings File "C:\Users\rdkbh\AppData\Local\Programs\Python\Python39\lib\site-packages\filer\settings.py", line 11, in <module> from .utils.loader import load_object File "C:\Users\rdkbh\AppData\Local\Programs\Python\Python39\lib\site-packages\filer\utils\loader.py", line 13, in <module> from django.utils import six ImportError: cannot import name 'six' from 'django.utils' (C:\Users\rdkbh\AppData\Local\Programs\Python\Python39\lib\site-packages\django\utils\__init__.py) If anyone knows what is causing the error (Based on the error message I believe it is something to do with cms_shiny) and how to fix it or if there are any better packages for integrating a shiny app into Django I would greatly appreciate it.

Django/Python: how to analyzing financial stock data (daily/monthly etc.)
I would like to do a lot of analysis/performance/statistics on my stock portfolio, which I plan to track with my app. E.g.: Week performance Month performance Year performance Best performer and a lot of other things I can't imagine right now... Where I'm struggling right now: - What is a good/the best way to archive this? - Also to show this info on a dashboard --> I think I should store this information somehow... But how to do this on a daily/weekly/whatever basis? --> I don't see a way to do such things while runtime? --> furthermore I need to know, when do do such thinks... It's end of the week so do weekly performance calculations... --> Maybe there is also an MVP solution, that can evolve into a top-notch solution?

Shared global variables among apps
Suppose I have two apps: data and visual. App data executes a database retrieval upon starting up. This thread here and this doc advises on how and where to place code that executes once on starting up. So, in app data: #apps.py from django.apps import AppConfig global_df #want to declare a global variable to be shared across all apps here. class DataConfig(AppConfig): # ... def ready(self): from .models import MyModel ... df = retrieve_db() #retrieve model instances from database ... return df In the code above, I am looking to execute ready() once on starting up and return df to a shared global variable (in this case, global_df). App visual should be able to access (through import, maybe) this global_df. But, any further modification of this global_df should be done only in app data. This thread here advised to place any global variable in the app's __init__.py file. But it mentioned that this only works for environmental variable. Two questions: 1 - How and where do I declare such a global variable? 2 - On starting up, how to pass the output of a function that executes only once to this global variable? -

Webpack/babel not compiling ReactDOM.render
Objective: I am trying to get webpack/babel to compile JSX so that I can make a website with react front end, and django rest api backend. I have gone through many tutorials and Stackoverflows, but never gotten JSX to compile to make combo work. I debugged for a LONG time, and found that the crux of the JSX problem seems to be centered around reactDOM.render. If I use react components without reactDOM.render, it all works, with is breaks down with errors such as "App.js:12 Uncaught ReferenceError: ReactDOM is not defined" or the one I get most often, "Module parse failed: Unexpected token (13:12) You may need an appropriate loader to handle this file type" here is the code-- my .babelrc file: { "presets": [ "@babel/preset-env", "@babel/preset-react" ] } webpack.config.js: module.exports = { module: { rules: [ { test: /\.(js|jsx)$/, exclude: /node_modules/, use: { loader: "babel-loader" } } ] } }; packages.json: { "name": "frontend", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "dev": "webpack --mode development --entry ./src/index.js --output-path ./static/frontend", "build": "webpack --mode production --entry ./src/index.js --output-path ./static/frontend" }, "keywords": [], "author": "", "license": "ISC", "devDependencies": { "@babel/core": "^7.14.6", "@babel/preset-env": "^7.14.7", "@babel/preset-react": "^7.14.5", "babel-loader": "^8.2.2", "react": "^17.0.2", "react-dom": "^17.0.2", "webpack": … -

Using Postgres roles and privilege in Django project
I am using Django Rest Framework with postgres. From the beginning of the project we used django-guardian to provide opportunity of using object permissions. But django-guardian can slow down all of the app when we have large amount of users, groups and permissions to them. What about of using postgres roles in django project? What about of storing each user as postgres role? What difficulties can we face? We will have a large number of users and roles, can it give problems to us if we will use postgres? -
