Get MIME type of file that is in memory - Python Django
I have a form where users can upload files. I only want them to be able to upload images. I have added that in the HTML form but need to do a server side check. I would like to do this check before I save the file to AWS S3. Currently I have this: from .models import cropSession, cropSessionPhoto import magic def crop(request): if request.method == 'POST': data = request.POST images = request.FILES.getlist('photos') crop_style = data['style'] if len(images) <= 0: messages.error(request, "At least one photo must be uploaded.") return redirect(reverse('crop-form')) crop_session = cropSession(crop_style=crop_style) crop_session.save() for image in images: mime = magic.Magic(mime=True) mime.from_file(image.file) upload = cropSessionPhoto(crop_session=crop_session, photo_file_name=image, photo_file_location=image) upload.save() else: messages.error(request, "An error has occured.") return redirect(reverse('crop-form')) return render(request, 'crop/crop.html') However, I get this error: TypeError: expected str, bytes or os.PathLike object, not BytesIO How do I properly pass the image to magic?

Why fetch does not include credentials everytime with option {credentials: "include"}?
I have been trying to fetch data from my djangorestframework api verifying through cookies. Before reaching to the main problem, My computer IP on LAN: 192.168.1.50 Running localhost at port 80: 127.0.0.1 Running django at port 8000: 192.168.1.50:8000 - (tried vice versa as well: 127.0.0.1:8000) Now, assuming my django is running on 192.168.1.50:8000, I figured out that if I send fetch request to djangorestframework from 192.168.1.50 the cookies are attached with the request.

How to serialize json to sql?
I have a list of words and I should send requests to an API and get the information about the words. I want to convert the API data which is in JSON format to SQL(my DB is PostgreSQL) format in Django. How can I do that? Do you know any good source to learn to serialize json to sql? I have just started learning Django. It is the API's JSON data: [ { "word": "hello", "phonetics": [ { "text": "/həˈloʊ/", "audio": "https://lex-audio.useremarkable.com/mp3/hello_us_1_rr.mp3" }, { "text": "/hɛˈloʊ/", "audio": "https://lex-audio.useremarkable.com/mp3/hello_us_2_rr.mp3" } ], "meanings": [ { "partOfSpeech": "exclamation", "definitions": [ { "definition": "Used as a greeting or to begin a phone conversation.", "example": "hello there, Katie!" } ] }, { "partOfSpeech": "noun", "definitions": [ { "definition": "An utterance of “hello”; a greeting.", "example": "she was getting polite nods and hellos from people", "synonyms": [ "greeting", "welcome", "salutation", "saluting", "hailing", "address", "hello", "hallo" ] } ] }, { "partOfSpeech": "intransitive verb", "definitions": [ { "definition": "Say or shout “hello”; greet someone.", "example": "I pressed the phone button and helloed" } ] } ] } ] this is my models.py: class Words(models.Model): word = models.CharField(max_length=50) american_phonetic= models.CharField(max_length=50) american_audio= models.URLField(max_length = 200) british_phonetic= models.CharField(max_length=50) british_audio= models.URLField(max_length … -
Django resets user permissions
I am building a site using React for the frontend and Django for the backend. The login page sends a request to this view function when the login button is pressed. @api_view(['POST']) def api_authenticate_login_view(request): body = request.data username = body['username'] password = body['password'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) content = {"authenticated": True} return Response(content) else: content = {"authenticated": False} return Response(content) When trying to access any other page in the site, a request is first sent to this view function to make sure the user is logged in @api_view(['GET']) def api_is_authenticated_view(request): if request.user.is_authenticated: content = {"authenticated": True} return Response(content) else: content = {"authenticated": False} return Response(content) If it returns false they are redirected to the login page. The issue is that this works great for most of our users, but for a select few, their user permissions in the provided Django admin page are constantly reset. What I mean by that is, in the user section of the Django admin page, you can select a user and see their permissions. On our page this shows a tick box next to the tags Active, Staff status, Superuser, and others(see image link below) Django user … -

ValueError at /login invalid salt
I am creating a django app and have run in to a problem with the login portion of it. Everything seems to be working fine but when I login in with the stored information I receive the ValueError with invalid salt. I've looked on here for solutions but nothing seems to be doing the trick. I tried using the encode('utf-8) solution but that doesn't work either. def login(request): if request.method != 'POST': return redirect('/') user = User.objects.filter(email = request.POST.get('email')).first() if user and bcrypt.checkpw(request.POST.get('password').encode(), user.password.encode()): request.session['user_id'] = user.id return redirect('/quotes') else: messages.add_message(request, messages.INFO, 'invalid credentials', extra_tags="login") return redirect('/') return redirect('/quotes') The issue seems to stem around the if user and bcrypt.checkpw() but I don't know what to do different? -
Django overriding filter() without change existing code logic

Django - Admin - Defualt Add/Change Form
I am wondering what is the best method and how to add in an informational field to the built-in admin add/change forms. Here is my case: I have 3 models each one is tied to another by a foreign key investor --> investment distribution --> investment So with proper a query I can easily look up from the distribution table which investor received which distribution If I want to add a distribution using the built in Django admin forms - the selection option for "investment" field for the distribution add form the dropdown list will include all the investments. The issue I am having is, if I have the same investment name for 2 investors, I do not know which option to select. So I would want the form to lookup the Investor using Investment --> Investor while on the distribution add/change this way when I add a distribution to an Investment I can select which investor it applies to. i.e. Investor Paul has Investments AAPL, GME, BB Investor Alan has Investments TSLA, GME Adding distribution for Investment GME ---> that form would should 2 GME options but I would like to know which is Pauls and which is Alans … -
How to integrate ldap to saml2 in Django
I have a django app that initially used LDAP to authenticate. Because of changing times I had to move the app over to use django-saml2-auth-ai, which initially I thought was fully working. A month after getting saml to "work" I noticed that this part of the code no longer worked. groups_owners=register.user.user_ldap.groups_names And I keep getting the following error. 'User' object has no attribute 'ldap_user' I use the command above to find all the ldap groups the user using the system belonged to. So how do I integrate SAML to work with LDAP or what do I need to add to SAML to get the ldap groups from the SAML authentication. From my saml trace tool all groups come from login.com/names/groupNames. When I try to query the attributes from SAML_AUTH they are empty SAML2_AUTH = { # Required setting 'SAML_CLIENT_SETTINGS': { # Pysaml2 Saml client settings (https://pysaml2.readthedocs.io/en/latest/howto/config.html) 'entityid': 'https://reg-dev.com', # The optional entity ID string to be passed in the 'Issuer' element of authn request, if required by the IDP.

Using User Model outside of Django Web App with Django Rest Framework
I have a model called File in my Django Web App. At the moment it looks like this: from django.db import models from django.conf import settings class File(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='files_owned', on_delete=models.CASCADE, default) file_name = models.CharField(max_length=20, default=None, blank=False, null=False) file_path = models.CharField(max_length = 50, default=None, blank=False, null=False) I have an endpoint using the Django REST Framework, where I can get a list of all Files and create a new File. Currently the endpoint looks like this: The POST request at the moment only allows for file_path and file_name to be entered, I want to be able to enter a user ID or a User model, but the script that uses the endpoint is outside of the django web app so cannot access the User model.

Django + MongoDB connection error after deployment to Heroku
I'm using Django(djongo) + MongoDB Altas(pymongo). So I developed this web app locally where I use Javascript's fetch method to read and write data to MongoDB.

I've tried these steps: Destroying a Postgres DB on Heroku How to change DATABASE_URL for a heroku application but nothing worked. I've also made my own MONGODB_URI config var but at no use.

Add model methods to Django model on a per-app basis? Model shared among apps
I am curious as to how best to handle this situation: I've got an app that has a User model (AbstractUser); it includes all the usual attributes (username, is_superuser, is_staff, etc.) This app is shared among multiple projects (which all have their own apps) The structure looks like something like this: Project X App A App B Project Y App A App C App D Project Z App A App E App F I'm at a point where I need to add a model method on that User model in Project Z to make life easier. It would do some business logic involving other models from the other related apps. Filtering stuff from App E and App F and what not. I can't add that method directly to the User model, because then the other projects would fail since they don't have access to those other projects.
