Uploading Python Django Project to GitHub
I am new in Django. My friend and I are starting to create projects to add them to our portfolio for job hunting purposes. I have a few questions for you - the professionals. Exactly which folders should be present on GitHub when uploading Django projects? Should folders like django_env, .idea, or files like .DS_Store and .gitignore be present there? Where exactly should the requirements.txt and README.md files be located? [enter image description here](https://i.stack.imgur.com/OnhPg.png) In general, how and what exactly should be uploaded to GitHub to present a project professionally? -
Django rest framework use router with pk in URL
I use DRF on my project and have some routes like: router.register(r'user', views.UserView, basename='user') router.register(r'user/{pk}/note', views.NoteView, basename='user') So I want to have an opportinuty to do GET,POST,PUT etc. actions with a note. Some part of NoteView: class NoteView(ModelViewSet, CreateModelMixin, RetrieveModelMixin, UpdateModelMixin, DestroyModelMixin): filter_backends = [DjangoFilterBackend] def get_queryset(self): return Note.objects.all() def list(self, request, *args, **kwargs): ... def create(self, request, *args, **kwargs): ... def update(self, request, *args, **kwargs): ... def destroy(self, request, *args, **kwargs): ... def get_serializer_class(self): if self.action == 'list': return NoteListSerializer return NoteSerializer But it doesn't work with this route, how should I define it? -
Proper use of prefetch_related() and select_related() in Django
I have a scenario which I believe is a good candidate to use prefetch_related() and select_related() in. As the documentation states that these should be used with care, I want to confirm that I am in fact improving performance rather than inadvertently hurting it. Here is the query: foo_items1 = Foo.objects.filter(bar=True) prefetch1 = Prefetch('baz__foo_set', queryset=foo_items1, to_attr='foo_bar1') foo_items2 = Foo.objects.filter(bar=False) prefetch2 = Prefetch('baz__foo_set', queryset=foo_items2, to_attr='foo_bar2') for item in queryset.select_related('baz').prefetch_related(prefetch1, prefetch2): print(item.baz.foo_bar1) print(item.baz.foo_bar2) Essentially, each item has a relation baz, which in turn has a reverse relation foo_set. I would like to optimally iterate over each item, and filter the foo_set on baz depending on whether bar is True or False. Am I doing this right? Or am I overengineering this? -

How to manage dependencies in a shared git subtree?
Lets say I have four git repos named A,B,C, & D A,B, & C (customer repos): Each repo contains a Django project for customers 1, 2, & 3 respectively Each customer exists in an air gapped environment From a user perspective, each of the Django projects are, more or less, functionally the same The repos have similar dependencies, although, they may vary in their versions (Django 2.x vs Django 4.x, PostgreSQL 13 vs 14, PostgreSQL vs SQLite, python package versions, etc.) D (common repo): This repo contains the code (Django apps & utilities) that is common across the customer repos This repo has been added as a git subtree to each of the customer repos The problem occurs when their is a dependency clash between the code in the customer repos and the common repo. For instance, if there was a line of code in the common repo that relies on Django 4.x and repo A depends on Django 2.x, then there will be errors. This same type of problem may occur with other dependencies. I've thought of two "solutions": Converge towards a single set of dependencies for all repos. In order to get this to work, however, each customer … -

Why am I getting a Bad Gateway Error sending bulk emails with Django
I have a need to send bulk emails, as much as 60 at a time, using an action in the Admin module. I do this by selecting certain cases and then running an admin action. Sometimes when I do this, not all 60 emails send. Sometimes they seem to go in batches of 20/30 and there could be a delay of a few hours between batches. This time I got an incomplete batch being sent and a 'Bad Gateway' error, with 8 emails not being sent. Those that what sent were sent twice. I can't see anything wrong with my code that would cause this. Any ideas would be greatly appreciated. I have the following Admin Action in my admin.py file: emailset=queryset.all().order_by('customer') for q in emailset: customer=q.customer email_to = q.customer.email html_content = render_to_string("accounts/email_template_staff_registration.html", {'q':q}) text_content = strip_tags(html_content) email = EmailMultiAlternatives( #subject "Staff Registration Email", #content text_content, #from settings.EMAIL_HOST_USER, # rec list [email_to], ['INSERT EMAIL ADDRESS FOR CC'] ) email.attach_alternative(html_content, "text/html") email.send() updated=len(queryset) self.message_user(request, ngettext( '%d Staff Registration Email was successfully sent.', '%d Staff Registration Emails were successfully sent.', updated, ) % updated, messages.SUCCESS) send_staff_reg_email.short_description="Send staff registration email" ```
