Using sourcedefender with Django
I have a python Django code that I wish to encrypt and can still run the django server from the encrypted folder. I read the PyPi specifically under Integrating encrypted code with Django and I could not get it to work. My python Django project structure is as follows: -- backend ---- config directory (where the settings.py file, wsgi.py are) ---- services directory (contains multiple directories of which all are encrypted, service1, service2, service3 which contains the Django rest framework APIs and code logic) ---- manage.py -- requirements.txt For me, it is not important the config directory, manage.py, and requirements.txt to be encrypted. What is important is that the services directory is encrypted. So how can I achieve that? Here is what I have tried. cd backend sourcedefender --remove encrypt --password 1234abcd --salt dcba4321 services In the manage.py, and wsgi.py I add import sourcedefender to the very top and then run python3 -m sourcedefender manage.py runserver and I get ImportError: manage Any help is appreciated. -

What is the advantage of binding to a socket instead of an IP?
I'm following this guide to deploy a flask application to production using gunicorn I get to this line gunicorn --bind 0.0.0.0:5000 wsgi:app and it works perfectly After that the author recommends this instead gunicorn --workers 3 --bind unix:/home/movieapp/app.sock -m 777 wsgi:app So my (dumb) question: what is the advantage of binding to a socket instead of an IP?

Issue with Datetime from database and Django
I'm trying to generate some basic chart data, but I cannot, yet anyways. Whenever I retrieve datetime values from Django models, it gives me this output: [print(i) for i in UserAnalyticsMeta.objects.all().values('created_at')[:3]] {'created_at': datetime.datetime(2022, 8, 15, 22, 43, 23, 88381, tzinfo=datetime.timezone.utc)} {'created_at': datetime.datetime(2022, 8, 15, 22, 48, 43, 944993, tzinfo=datetime.timezone.utc)} {'created_at': datetime.datetime(2022, 8, 15, 22, 48, 49, 95255, tzinfo=datetime.timezone.utc)} Which translates to: 2022-08-15 22:43:23.088381+00:00 2022-08-15 22:48:43.944993+00:00 2022-08-15 22:48:49.095255+00:00 However, when I try to print out the date, this is the output I get: [print(i) for i in UserAnalyticsMeta.objects.all().values('created_at__date')[:3]] {'created_at__date': None} {'created_at__date': None} {'created_at__date': None} While I expect: 2022-08-15 2022-08-15 2022-08-15 What I've also noticed is that an old function I used also doesn't work anymore, and I feel like it has something to do with this. select_data = {"date_created": """strftime('%%m/%%d/%%Y', created_at)"""} qs = self.extra(select=select_data).values('date_created').annotate(models.Sum("page_visits")) return qs Now gives me the error: OperationalError at /admin/app_name/model_name/ (1305, 'FUNCTION app_name.strftime does not exist') Any help would be appreciated!

How to execute javascript code after htmx makes an ajax request?
Im currently building a website with django and htmx and i like the combination so far. Lets say I use an htmx attribute on a button to replace a div in the DOM with another div that is supposed to contain a wysiwyg editor. Now the wysiwyg editor has to be initialized with javascript. How do I do this? Can I just return the script tag under the editor div that is being requested with htmx? Wouldnt that be also a little ugly or bad practice because youd have script tags in the middle of the html body? Whats the best way of solving this? Thanks in advance -

This is my last brain cell speaking. I have a model called Post with title, body, author, logo and pub_date fields. There is a page in my app that the user can Update/Edit the post. I want the user to be redirected to the Post's Detail page if they tried to access it without being logged in. The problem is that I can't reference the Post's pk to redirect the user to the related page, If I want to put it simply: the user trying to access .../2/edit/ will be redirected to .../2/ if they aren't logged in I Tried using LoginRequiredMixin to block the user but I can't redirect the user to the relative details page. urls.py: urlpatterns = [ path('', PostListView.as_view(), name='index'), path('<int:pk>/', PostDetailView.as_view(), name='details'), path('new/', PostCreateView.as_view(), name='new_post'), path('<int:pk>/edit', PostUpdateView.as_view(), name='update_post'), ] views.py: class PostUpdateView(LoginRequiredMixin, UpdateView): model = Post login_url = reverse_lazy('details', args=[self.object.pk,]) form_class = PostUpdateForm template_name = "posts/update_post.html" I also tried: class PostUpdateView(LoginRequiredMixin, UpdateView): def get_login_url(self) -> str: super().get_login_url() UpdateView.get(self, self.request) self.login_url = reverse_lazy('details', args=[self.object.pk,]) model = Post form_class = PostUpdateForm template_name = "posts/update_post.html" But it returns an empty/none value Is LoginRequiredMixin even the right way to do this? I know this can easily be achieved without … -

Limit the choices of a choice field in the model class
This SO answer shows how to limit a choice field in the form. However, I have a choice field with options that should never be shown to the user. Hence, I want to limit the choice field options in the model class to adhere to the DRY principle and to prevent myself from forgetting to adding code in future forms. Any idea how to achieve this? -
how to declare a serializer field containing list of ids in django
Models: class Author(Base): name = models.CharField(max_length=100, unique=True) class Book(Base): name = models.CharField(max_length=100, unique=True) class AuthorBookAssn(Base): author = models.ForeignKey(Author, on_delete=models.PROTECT) book = models.ForeignKey(Book, on_delete=models.CASCADE) I have an api to create a book, and along with the book data we would also get a list of author ids how should the serializer field be created such that it is a list of ids. for example: [1, 2, 3] This field would not be present in any models we only need to use these fields to create records in the AuthorBookAssn table. -
Separate Django permissions per group per user's companies
I have a CustomUser model, each user could be linked to multiple companies. I have initiated my application with 3 generic Django groups; viewer, editor, and supervisor and each user could be a member in only one group. Permissions I have used some global Django permissions like the {app_label}.add_{class_name} permisison with the editor group for an instance. In parallel, I used also django-guardian to have some object-level permissions to get deeper with my objects' permissions as they vary depending on some of the object attributes' values. So, at the end of the day, each user (depending on his group) has some global permissions and some object-level permissions. It works fine that way with no problem so far. Problem As stated earlier, each user is linked to multiple companies. Additionally, each object in my database is linked to a specific company. So, I need to have a higher level of permissions so that each user can deal and interact ONLY with the objects that are linked to one of his companies weather he/she is a viewer, editor, or supervisor. Proposed solutions Those are the solutions that I thought about, but each one of them has some drawbacks and I don't prefer …
