calling a synchronous function asynchronously in django-graphene mutation
My mutation contains a function which calls an API to send SMS. Since this function's execution may take some time, and its result doesn't have anything to do with what the mutation returns (It does not have to be send back to the client); I prefer to run it asynchronously. So that the mutation gets executed as fast as possible. Here's my code: class MyMutation(graphene.Mutation): class Arguments: phone = graphene.String(required=True) success = graphene.Boolean() @classmethod def mutate(cls, root, info, phone): ... ... myfunction() #The client should not wait for this function's execution. return MyMutation(success=True) I couldn't find a proper way to do this in django-graphene's docs. -
Django docker-compose: how to handle migrations and collect static
I have a django app that I have been trying to "Dockerize" . I am pretty close but I am facing a small issue. Essentially, I am trying to understand how should I handle the fact that everytime I run docker-compose up I should run python manage.py migrate. Any suggestions?

Is there a Pythonic way to type a function parameter to a specific django model object?
Let's say I have a model like this: class Foo(): name = models.CharField() And a function like this: def update_foo_name(foo_object): foo_object.name = "New Name" Is there a way to enforce typing on update_foo_name(), so that only a valid object of Foo can be passed here? Ie something like update_foo_name(foo_object: Foo.objects). Apologies if this has already been asked, and thank you in advance for any responses! -
Replit: Why am I getting PR_END_OF_FILE_ERROR for my Django project?
I run a Django repl within Replit. However, I often cannot access the browser preview of my project because of a "PR_END_OF_FILE_ERROR" in Firefox. I also tried using Brave and Chromium, but no luck with them either: they showed an "ERR_CONNECTION_CLOSED" error. When I reached out to Replit Support, they said, "This looks like a problem that someone in our community can help with." Can any of you help? -
Ignore certain fields on update depending on condition
Description: The goal is to update all Spotlight fields on PUT/PATCH (update/partial update) if its status is YELLOW. If status is RED || GREEN, it should update only its status and ignore any other fields. The workaround presented here is kind of smelly and it produces misleading responses when using PUT. Is there any Django way to achieve this better than the presented workaround?

Making price range filter in django
Hi guys I have built an ecommerce site using Django. I want to filter the price ranges and I have found the perfect javascript and html tempelate for that. Problem is I don't have javascript knowledge to put that to my advantage. Here are the codes. Javascript var slider = document.getElementById('price-slider'); if (slider) { noUiSlider.create(slider, { start: [1, 999], connect: true, tooltips: [true, true], format: { to: function(value) { return value.toFixed(2) + '$'; }, from: function(value) { return value } }, range: { 'min': 1, 'max': 999 } }); } html code <div class="aside"> <h3 class="aside-title">Filter by Price</h3> <div id="price-slider"></div> </div> Views def category_products(request,id,slug): products = Product.objects.filter(category_id=id) minmaxPrice = products.aggregate(Min('price'), Max('price')) context={'products': products, 'minmaxPrice':minmaxPrice,} return render(request,'category_products.html',context) Now it shows ranges from 1 to 999 as fixed in the javascript code, but I want it to be dynamic based on the range "minmaxPrice" in views, like this "minmaxPrice.price__min" and "minmaxPrice.price__max". Thank you in advance!!! -
The genre system in django
I'm making a genre system on django based on the videos. I came across a problem that when I select a certain genre and click on the find button, I am thrown a link of the type '/filter/?genre=2', but the problem is that the found books are not displayed, I know for sure that they are, the problem is specifically in the template.The genres themselves also disappear from the sidebar, but the header tag and some others remain.

Validate parent model foreign key by child class in Django
Let's say I have the following parent models in my Django application: class Location(models.Model): name = models.CharField(max_length=100) class Exit(models.Model): location = models.ForeignKey(Location, on_delete=models.CASCADE, related_name="exits") closed = models.BooleanField() And two pairs of corresponding child models: class Submarine(Location): size = models.FloatField() class Hatch(Exit): diameter = models.FloatField() class House(Location): height = models.FloatField() class Door(Exit): width = models.FloatField() height = models.FloatField() In this setup it is possible for a House to have a Hatch as one of its Exits, as well as for a Submarine to have a Door. Is there a way to explicitly prevent this from happening? Ideally, I would like an exception to be thrown on attempt to set an invalid foreign key. Moving the location field from Exit to Hatch and Door is not an option, because I want to be able to use constructions like the following: open_locations = Location.objects.filter(exits__closed=False) and avoid duplication (i.e. writing separate functions for Houses and Submarines). Maybe the limit_choices_to constraint could be helpful, but I didn't manage to figure out how to apply it here. -
CSRF verification fails after having deployed Django on nginx and waitress
I have used the build-in CSRF module in Django, which worked on localhost. After deploying on nginx and waitress on windows server, it gives me the following error: Forbidden (403) CSRF verification failed. Request aborted. Help Reason given for failure: Origin checking failed - https://95.18.243.298 does not match any trusted origins.

How do I best restrict by user and by data model using Django?
I'm using django-guardian and I encountered some issues with the default mixins. And I want to know if there's a better way to do this. Problem: If I want to limit access at both the model and object levels, using these two mixins (PermissionRequiredMixin, PermissionListMixin) is not a very easy task. Because the permissions_required attribute is overridden. To get around this I had to create a new attr "object_permission" and do the following: Model Looks like: # Create your models here. from django.db import models from localflavor.br import models as localModels from django.contrib.auth.models import AbstractUser class User(AbstractUser): pass class Customer(models.Model): user: User = models.OneToOneField(User, on_delete=models.CASCADE) def __str__(self): return f'{self.user.first_name} {self.user.last_name}' class Company(models.Model): user: User = models.OneToOneField(User, on_delete=models.CASCADE) customer = models.ForeignKey(Customer, on_delete=models.CASCADE, related_name='comapnies') def __str__(self): return f'{self.user.first_name} {self.user.last_name}' class Project(models.Model): name = models.CharField(max_length=100) owner = models.ForeignKey(Customer, on_delete=models.CASCADE, related_name='projects') class Meta: permissions = (('read_project', 'Read Project'),) def __str__(self): return self.name class House(models.Model): rooms = models.IntegerField() postal_code = localModels.BRPostalCodeField() project = models.ForeignKey(Project, on_delete=models.CASCADE) Here I needed to create a new attribute ("object_permission") to limit object-level access in the View: class ProjectsListView(PermissionRequiredMixin, PermissionListMixin, ListView): template_name = 'home/projects.html' model = models.Project permission_required = ["homepage.view_project"] object_permission = ["read_project"] redirect_field_name = 'next' login_url = 'login/' get_objects_for_user_extra_kwargs = … -

Django dumpdata: "Unable to serialize database" error due to a BitFlagField var
I've been trying to create a fixture of a table, but it's always been failing with the following message: CommandError: Unable to serialize database: __str__ returned non-string (type method). The stacktrace was equally unhelpful, pointing to one of the Django files as the culprit. After some fiddling about, I've managed to pinpoint the culprit in the models.py: class UserExtra(model.Models): (...) blocked = BitFlagField( flags=( 'manual', 'system', 'tries', 'expired', 'inactivity', 'nosys_nobypass' ), db_column='ind_block' ) The class is only a list of vars and lacks any sort of function.
