How to link between django views components
Actually, I am pretty new in Django. I have created three views in my views.py. This is my following code in views.py : from django.shortcuts import render import pymongo from .models import * from .serializers import * from .forms import * from .codes.scraping import scrap def home_view(request): context = {} context ['form'] = Scraping() return render(request,'home.html',context) def loading_view(request): return render(request,'loading.html') def datatable_view(request): client = pymongo.MongoClient("mongodb://localhost:27017/") db= client["aliexpress_db"] col = db["segment"] products = col.find() context = {'products' : products} return render(request,'datatable.html', context) My question is that I want to get a method in order to get the home_view first then my loading_view while the scraping is processing then my datatable_view. I don't know how to link between these views. I am completely beginner. Any help would be great. -
React index.js in Django Project doesn't render imported components
I am trying to build a project with a hybrid architecture with Django as Backend and React as Frontend. For this I use Webpack and Babel to pipe the js files into djangos static index-bundle.js. However I encountered a problem which I don't understand. Apparently I can not import other components into my index.js react file. Instead, the root div stays empty. While this works and the text is visible in the Browser... ReactDOM.render( <h1> React in Django </h1> document.getElementById('root') ); ... importing it from another component doesn't work (div "root" has no inner elements) ReactDOM.render( <App />, document.getElementById('root') ); class App extends Component { render() { return ( <h1>React in Django</h1> ) } } In the end I want to have the "normal" react behaviour inside the django project. -

Deleting object in Django
What is the best practice to delete object in Django? Using simple "a tag" with the link to the view like this: def deleteStudent(request,id): student = get_object_or_404(Student, id = id) student.delete() return redirect('/') or using post method: <form method="POST"> {% csrf_token %} Are you want to delete this item ? <input type="submit" value="Yes" /> <a href="/">Cancel </a> </form> and in views: def deleteStudent(request, id): student = get_object_or_404(Student, id = id) if request.method =="POST": student.delete() return redirect('/') return render(request, "delete_view.html") I saw in courses that people use both of the methods (it's example code, I'didn't test it or secure views). So if we can delete objects with "POST" method, can I say in the job interview that "POST method can be also used to delete objects"? Thanks for all answers. -

Django Microsoft Graph Authentication
I'd like users to be able to login to my Django app using their Microsoft personal, work or school account. I have no interest in any profile or other data from the user's account. I just want authentication. I've been playing with django-allauth and and Azure portal and have successfully set things up so I can log in with my personal outlook.com account. I've set the AD tenants up to allow for personal and institutional accounts. I've successfully served the .wellknown json and was able to verify the app in Azure. I run into trouble when I try to log in with a Microsoft 365 work or school account. The consent form shows the app as "unverified" and indicates that the app wants profile information and to store data. I ended up in a rabbit hole of Microsoft AD documentation about MPN IDs and such. Before I go further I want to know if I what I want to do is even possible. Keeping in mind that I'm not interested in profile information, can I achieve authentication in Django with a users Microsoft Work or School account? If so, what do I have to do? -

Cross-Origin-Opener-Policy header error when making GET request in Django
I'm making a stock app which displays live market data via Alpaca API. The error is The Cross-Origin-Opener-Policy header has been ignored, because the URL's origin was untrustworthy. It was defined either in the final response or a redirect. Please deliver the response using the HTTPS protocol. You can also use the 'localhost' origin instead. Here's how I'm making the request: symbol = 'AAPL' url = f'https://data.alpaca.markets/v2/stocks/{symbol}/trades/latest' requests.get(url, headers={ 'APCA-API-KEY-ID': API-KEY-ID, 'APCA-API-SECRET-KEY': API-SECRET-KEY, }) My request works when market is closed, but not open. However, if I run the code in a console during open hours, it still works so the API endpoint should be correct. In Django settings, I have: ALLOWED_HOSTS = ['market-master.herokuapp.com'] CSRF_TRUSTED_ORIGINS = ['https://market-master.herokuapp.com'] My site is https, is there an additional header I'm missing?
