Is there a way to get custom user model password before it gets hashed on Django
A custom user model was created in Django. After we create a user, we then send that user details to firebase: # Sync User to FireBase Authentication: @receiver(post_save, sender=Account) def add_user_to_firebase(sender, created, instance, *args, **kwargs): if created: auth.create_user(**{ "uid":instance.firebase_uid, "display_name": instance.username, "email": instance.email, "password": instance.password }) but this is where the issue comes in: when we send the password instance.password the password is then hashed before it gets sent to firebase. We want the unhashed password to get sent to firebase instead. Is that possible? -

Django employee working hours plan app based on date
I need to make an app that runs based on date. The idea is, have a total count on work hours that a divided by some number to get the right number of open positions to be filled with employees. When employees filling positions they should have their status and working hours bound to a from date, to date field, multiple from date, status, working hours, to date fields are necessary. And now visitors should have the option to input some date to view the future of open positions and needed working hours while also shown the employees with the status and working hours within that date range. I want to use django for that but have no clue how to accomplish such task. My idea was bound this whole thing into a calendar and let visitors just click on some date to show them the data but also dont know how to implement that. Do you have any ideas or direction you could guide me to ? -

From within a Django Rest API, how can I return an image from an external image API that requires a key in the address
I am writing an API with the Django Rest Framework that returns a random image from an external image API that I have access to, which requires a private key in the url: imgapi.com/193811&key=2s3kp72a82 Without exposing the key, I want an endpoint in my API to return the image from this url: mysite.com/randomimage I will ise this endpoint as part of a web app that has a button that when clicked, displays a random image loaded via JS with an AJAX call to the endpoint. One of the approaches I tried was: @api_view(['GET']) def random_image(request): response = requests.get('api url with secret key') if request.method == 'GET': return HttpResponse(response.content, content_type="image/jpeg") however when I go to this endpoint in my browser, I get a server 500 error. When I make this a POST endpoint instead, I can get the image to return in Postman, but not in the browser. I have also tried to display the GET request using a Django template, but I cant get that to work either. -
