Django: avoid multiple DB queries for recursive model
I have following models: class Topic(models.Model): ... class Article(models.Model): ... class ArticleInTopic(models.Model): topic = models.ForeignKey(Topic, on_delete=models.PROTECT) article = models.ForeignKey(Article, on_delete=models.PROTECT) depends_on = models.ForeignKey(ArticleInTopic, on_delete=models.PROTECT) class Meta: unique_together = ('topic', 'article', 'depends_on') With this models set I'm trying to express the following situation: there are some studying topics, each consists of multiple articles. However, in order to learn a topic one should read the articles related to the topic but not in any order, rather in order defined by article dependencies. This means that in context of a topic an article may have another article which is required to be read before reading this article. It is guaranteed that the article on which the current article depends on comes from the same topic. So, basically, this whole structure looks like an acyclic (it is guaranteed) graph with parent-child nodes relation. In the business logic of my app I'm going to sort the graph topologically so I can tell the user which Article to read 1st, 2nd, etc. However, the problem is the way Django fetches ForeignKey's data from the database. AFAIK it uses N+1 request to fetch all foreign keys. There is a solution to it - using select_related but this … -
Trying to create a one-time calculated field in Django model
Building my first Django app, and I'm running into a snag. I have a Django model that creates Job objects, and I want each job code to be unique and auto-generated, with a particular format. The format is: aaaMMnnYYYY, where aaa is a 3-letter client identifier that we set, nn is a counter that represents the nth job from that client in that month., and MM and YYYY are month and year respectively. e.g., for the 3rd job from client "AIE" in feb 2023, the ID would be AIE02032023. Using a calculated field with the @property decorator causes the field to be continuously updated, so I'm trying to do this by modifying the save() method. There's also a related Cost object that has Job attributes via Foreign Key. The way I have it now, when I add a Cost, the 'iterating' part of the job code iterates, changing the job code, which causes uniqueness errors as well as URL errors (I'm using the job code in the URLConf. As a side note, I'd also like to be able to override the job code. Is there a way to set flags within a model, such as job_code_overridden = False, etc.? Here's … -

This backend doesn't support absolute paths Django Google Storage
I have a Django app in Compute Engine. I set up a Google Cloud Storage as storage for my media files. In one endpoint, you can request for the file information including the file path. When I POST for this endpoint it returns: This backend doesn't support absolute paths. For simplicity my view for the endpoint look like this: class FilesView(APIView): permission_classes = (permissions.AllowAny,) def post(self, request): ... path = layer.file.path response_message = {'file': path } return Response(response_message, status.HTTP_200_OK) I have done the following: Create a service account and download the JSON. Configure it to my Django settings. I added the service account to the permissions in the bukcet i.e. set as Storage Admin. I added allUsers to have permission: Storage Legacy Object Reader. I changed the bucket from Uniform to Fine-grained. Here is in my settings: DEFAULT_FILE_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage' STATICFILES_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage' GS_BUCKET_NAME = 'sample-bucket' GCP_CREDENTIALS = os.path.join(BASE_DIR, 'sample-bucket-credentials.json') GS_CREDENTIALS = service_account.Credentials.from_service_account_file(GCP_CREDENTIALS) -
Link Django models together via GenericKey?
i have the following models: class Team(models.Model): users = models.ManyToManyField("User") class User(AbstractUser): ... class Subscription(models.Model): team = models.ForeignKey("Team", on_delete=models.CASCADE) name = models.CharField(max_length=64) class Package(models.Model): name = models.CharField(max_length=64) # packageA, packageB max_activation_number = models.PositiveIntegerField(default=1) class Activation(models.Model): subscription = models.ForeignKey("Subscription", on_delete=models.CASCADE) package = models.ForeignKey("Package", on_delete=models.CASCADE) created = models.DatetimeField() class PackageA(models.Model): ... class PackageB(models.Model): ... A team has one subscription and it can activate one or more package and the same package could be activated more than one time. (number of times specified with "max_ativation_number") Example: A team has a subscription called Suite and the available packages are: EmailAccount and Calendar The team choose to activate 3 EmailAccount and 2 Calendar (packages are not tied to each other) For that reason the team could activate the same package more times. For every activation i need to create a new instance on PackageA or PackageB (it depends on the choice a team made) and then i should "link" to that instance somehow. Should i use GenericKey field inside Activation model? I not only need the name of the chosen package but I also need to figure out which instance. -
Firebase get method returning a list for one object of objects and a dict for another
Im using django with firebase and have 2 objects of objects in the database, everything about them is the same, the way i store them in the database, the way im trying to access them.

[Django Rest Framework, try to call a specific header

TemplateDoesNotExist at /accounts/login/
I have checked the answers here, here, here, and here, and though I am getting the same error apparently I have a different root cause since those answers do not work for me. Here's the problem: I am using Django's LoginView, overriding the template name, but it only sometimes works. If I get to the login screen from the navbar, it works great, but the same url when gotten to from a different method throws a template does not exist error. My URLs file: from django.urls import path from django.contrib.auth import views as auth_views from . import views app_name = "accounts" urlpatterns = [ path( "login", auth_views.LoginView.as_view(template_name="accounts/login.html"), name="login", ), path("logout", auth_views.LogoutView.as_view(), name="logout"), path("signup", views.SignUp.as_view(), name="signup"), ] I have a nav item for the login screen, and it works great. The relevant section in the template: {% else %} <li class="nav-item"><a href="{% url 'groups:all' %}" class="nav-link">Groups</a></li> <li class="nav-item"><a class="nav-link" href="{% url 'accounts:login' %}">Login</a></li> <li class="nav-item"><a class="nav-link" href="{% url 'accounts:signup' %}">Sign Up</a></li> {% endif %} If someone clicks the login link in the navbar, it takes you to http://127.0.0.1:8000/accounts/login and works great.

Django create and register model backed by mongo

Cannot runserver from Pycharm using Vagrant Interpreter. Path for manage.py is wrong, don't know where to fix it
I'm trying to configure correctly Pycharm (for a Django project) + Vagrant, to launch the runserver remotely from my host machine (and thus enable debugging). The command for such seems simple but the path is wrong, so it fails. It tries to run /home/vagrant/.virtualenvs/[myprojname]/bin/python /vagrant/[myprojname]/manage.py runserver 0.0.0.0:8000 Second parameter is wrong, it's missing either the initial /home/ or it isn' a relative path. My run configuration I'm running a host windows machine, and a vagrant ubuntu 20.10 guest VB. I setup my remote interpreter with what I suppose are the right parameters. In my vagrantfile I have setup the shared folder as following (Project name is PoeMogul) config.vm.synced_folder "PoeMogul", "/home/vagrant/PoeMogul" In my vagrant box, everything is setup fine (I think). I have my venv. In my /home/vagrant/PoeMogul dir i can see my working directory from PyCharm. I can manually (through vagrant ssh) run the server. But i cannot make Pycharm invoke the manage.py file correctly, it tries to access "/vagrant/..." and not "/home/vagrant/...". -
How to paginate multiple queries in a single function-based-view or class-based-view in django?
I have a search function that queries multiple models. I have the expected results displayed in a html template and so far all is fine.

I have other class based views working well paginating single models. def search_results(request): if request.method == 'POST': searched = request.POST['searched'] books = Book.objects.filter(description__icontains=searched, title__icontains=searched).order_by('-id') sermons = Sermon.objects.filter(description__icontains=searched, title__icontains=searched).order_by('-id') other_sermons = SermonsByOtherFathers.objects.filter(description__icontains=searched, title__icontains=searched).order_by('id') other_books = BooksByOtherFathers.objects.filter(description__icontains=searched, title__icontains=searched).order_by('-id') context = { 'searched': searched, 'sermons': sermons, 'other_sermons': other_sermons, 'books': books, 'other_books': other_books, } if searched == "": return HttpResponse('Please type something in the search input.') return render(request, "search_results.html", context) This is a simplified version of my html template. {% for book in books %} <tr> <td> <a href="{{ book.book_instance.url }}"> {{ book.title }} </a> <p> {{book.author}} </div> <p> {{ book.category }} </p> <p> {{ book.description }} </p> </td> </tr> {% endfor %} <-- ...and the same loops goes for the rest of the other querysets. --> {% for book in other_books %} <-- code here --> {% endfor %} {% for sermon in sermons %} <-- code here --> {% endfor %} {% … -

Django: How to go to a URL with select option using views.py GET or POST instead of a JavaScript function
I show two solutions, one with GET, the other with POST. In both I have errors. GET case In templates I have the following form (I omit the JavaScript call that submits the form) <form id="myform" action="{% profiles:profile-detail slug=x.user %}" method="GET"> <select> <option value="view">View</option> </select> </form> In views.py I have class ProfileView(DetailView): model = Profile def get_object(self, *args, **kwargs): slug = self.kwargs.get('slug') user = User.objects.get(username=slug) profile = Profile.objects.get(user=user) return profile This approach takes me to the profile page of {{x.user}}=user1, however when I click the backward button in the browser, it goes from mypath/user1 to mypath/user1?. I don't like this ?. To go back to the previous page I would need to click the backward button twice. I would like to click it only once and remove this ? transition step. POST case In templates: <form id="myform" action="{% profiles:profile-detail slug=x.user %}" method="GET"> {% csrf_token %} <input type="hidden" name="slug" value={{x.user}}> <select> <option value="view">View</option> </select> </form> In views.py class ProfileView(LoginRequiredMixin, DetailView): model = Profile def post(self,request,slug): myslug = request.POST.get(slug) User = get_user_model() user = User.objects.get(username=myslug) profile = Profile.objects.get(user=user) return profile This shows the error DOESNOTEXIST. User matching query does not exist. the error page shows myslug=None and slug=user1. What would be an …
