Django REST Framework User Registration Privacy Issue: Looking for best practice to not show exception if user with given email exists already
I am suprised I have not found anything on the web regarding the following issue which I thought should be common? I may just have used the wrong search terms so I am happy to receive links with more info. My problem is that when using ACCOUNT_EMAIL_VERIFICATION = 'mandatory' I want to not give a clue to any user except the owner of an email address whether that mail is registered on my website, i. e. not show a "A user is already registered with this e-mail address." if an existing email is entered. My assumption is that that would require for the registration endpoint to return the same response independent of whether the email exists or not. I see several possible approaches, but none seems to be a good one: Use a custom exception handler to remove the exception in question from the error messages sent. That means I have to somehow identify the abovementioned exception among all error messages sent so I can still keep the others in the response. I guess I have to identify the exception message by a string the actual error message (possibly dependent on language settings?). If there are multiple error messages I … -
Connect to Django Admin over SSH using Apache and Port Forwarding
I would like to be able to restrict access to the Django admin for all requests, except for requests that come from inside the server, after connecting via SSH (which I have set as the default on my Ubuntu server) using port forwarding. I am using Ubuntu OS, and Apache server to serve my Django app with a React front-end here. I came across a wonderful description of how to do this with Nginx here. I also saw that it is possible to use <Location> blocks to restrict access to a URI. Can someone please assist here? -
Empty querydict request.data using Django Rest Framework
I am using Django REST Framework, and I use a post request but I have some troubles... I mean when I send this using the parameter Media Type : application/json : { 'name': 'List', 'comment': 'test', 'description': '', 'renders': [ 'application/json', 'text/html' ], 'parses': [ 'application/json', 'application/x-www-form-urlencoded', 'multipart/form-data' ] } It works very well. But when I send that : { 'name': 'List', 'comment': 'test', 'description': '', 'times': [{ 'start': '2020-11-10T14:00:00Z', 'end': '2020-11-10T20:00:00Z', }], 'renders': [ 'application/json', 'text/html' ], 'parses': [ 'application/json', 'application/x-www-form-urlencoded', 'multipart/form-data' ] } I got an empty querydict for the request.data. Could you help me please ? Thank you very much ! -
CSRF cookie not set Django cross-site iframe in chrome
I'm trying to use an iframe of my django site in a different domain, however whenever I submit a form, It says the CSRF cookies is not set. This occurs in chrome and safari. I am running Django 3.1.0. I've tried adding the following settings in my settings.py: SESSION_COOKIE_SAMESITE = 'None' SESSION_COOKIE_SECURE = True X_FRAME_OPTIONS = 'ALLOWALL' CORS_ORIGIN_ALLOW_ALL = True CORS_ALLOW_CREDENTIALS = True CSRF_COOKIE_SECURE = False CSRF_COOKIE_SAMESITE = None CSRF_COOKIE_HTTPONLY = False CSRF_TRUSTED_ORIGINS = [ 'otherdomain.com', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', ] Further, I can confirm the csrf token is being set in the form using: {% csrf_token %} Lastly, I've also added the @xframe_options_exempt decorator to the form page. Unfortunately the csrf exempt decorator is not an option for me. I've tried clearing my cookies, though it does not solve my problem. Any help would be greatly appreciated! -
Django add User and Listing model to a Watchlist model
I'm trying to add a Listing model for an eCommerce app to a Wishlist model, but I'm not quite sure where I'm going wrong.

SynchronousOnlyOperation error when upgrading from python 3.6 to python 3.7 using django channels
I've been attempting to upgrade python from 3.6 to 3.7 for our Django & Django channels application. With that change, Django throws a SynchronousOnlyOperation anytime any HTTP request is made (even if it has nothing to do with websockets). My guess is that somehow the python upgrade has made the Django check more strict. I believe that django channels is serving both the HTTP requests and websocket requests so it expects all code to be async compliant. How do I get Django channels runserver to run the wsgi app synchronously, while the channel consumers asynchronously. # project/asgi.py application = ProtocolTypeRouter({"http": get_asgi_application(), "websocket": routing}) # project/wsgi.py application = get_wsgi_application() Stacktrace: It's clear to me that the auth middleware that is running for a normal wsgi view is not async compliant, how can I get it to run in a sync environment?

Is there a way to list the column properties of my PostgreSQL tables?
I'm working in a Django project utilizing an old database from the project. The problem is: Migrating with Django don't give me a good fresh database, some fields that should be nullable are not, some are missing, and this breaks the site. The old database is missing some fields too. I need to compare the old database with the new one, but since there are almost 70 tables and lots of columns, I was hoping there is a way to let me visualize this in a easier way... Any ideas? -
How to Convert UTC Time To User's Local Time in Django
I undrestand that this question is repeated, but unfortunately I cannot find any answer. My impression is that Django already takes care of converting server time to local user as long as I have TIME_ZONE = 'UTC' USE_TZ = True in my settings. Even more if the db is postgresql that setting also doesn't matter and every thing will be still converted. however I tried all the followings: {% load tz %} {{ obj.date }} {{ obj.date|localtime }} {{ obj.date | timezone:"Canada/Mountain" }} and only last one works and the rest gives me UTC time. Last one also is not useful as the time would be only correct for users in that zone. I was wondering if I am missing anything here. I have a very simple test model: class TimeObject(models.Model): date = models.DateTimeField(auto_now=True) -

Django REST Framework - Migrate fails when splitting serializers
I'm trying to split the models, serializers and views of my app to get small, readable files. So, I moved from this: app/ recipes/ migrations/ models.py serializers.py views.py To this: app/ recipes/ migrations/ models/ __init__.py tag.py serializers/ __init__.py tag.py views/ __init__.py tag.py Somehow, everything was working fine until I restarted Docker.

Adjusting images in django
I am working on a django website, the code works pretty well but I'd like to make a few adjustments in order to make the web more professional. There's a section in the web called latest posts.

Remove file objects from children models on delete
My model File has as main purpose to link multiple files for one Invoice. class File(models.Model): invoice = models.ForeignKey(Invoice, related_name = 'files', on_delete = models.CASCADE) file = models.FileField(upload_to = 'storage/invoicing/') def delete(self, *args, **kwargs): self.file.delete() return super(File, self).delete(*args, **kwargs) When i delete one instance of my model File, the file stored in storage/invoicing is also deleted because of my modified delete() method. However, if i delete the instance from the parent model Invoice, the file is not deleted. Even with the File instance being removed from the database, the file is still acessable. How can i code the parent model to delete everything from the children model, including the files? I've searched a bit and i know that probably signals like post_delete can help me here, but i really don't know how to code it. -
Django Rest Framework serializing queryset fetchedn with value_list

How can i handle overlaps, reservation and open/close times for a business with django?
Im working on a project that is for making reservations, the business that are registered have open and close times: open_times = [{opens: 09:00am, closes: 13:00}, {opens: 15:00am, closes: 21:00}] --> Naps are really common in Uruguay so everyone closes theirs business after lunch xD an between those times an user can make reservations.
