PyCharm Cannot load Django project after last update
I just opened PyCharm to work on a small side-project. A django app that does some stuff (I think irrelevant to the problem.) I am on Tumbleweed Operating System: openSUSE Tumbleweed 20240517 KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.0 Kernel Version: 6.8.9-1-default (64-bit) Graphics Platform: Wayland Processors: 12 × 12th Gen Intel® Core™ i7-1255U Memory: 31.0 GiB of RAM Graphics Processor: Mesa Intel® Graphics Manufacturer: LENOVO Product Name: 21C1002HGE System Version: ThinkPad L14 Gen 3 and I don'T know, maybe it's related to "the big tumbleweed update with kde6 and changing to wayland" or whether it's a pyCharm problem: The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/home/kevin/PycharmProjects/VocabelTrainer/manage.py", line 22, in <module> main() File "/home/kevin/PycharmProjects/VocabelTrainer/manage.py", line 13, in main raise ImportError( ImportError: Couldn't import Django.

Is there a better way to update all relation rows with `ForegnKey` relation in `Django ORM`
I have two models, one like this: class PhysicalSensor(models.Model): name = models.CharField(unique=True, max_length=255) def __str__(self) -> str: return self.name class Sensor(models.Model): physical_sensor = models.ForeignKey(PhysicalSensor, on_delete=models.RESTRICT, null=True, blank=True) So, when I want to add a PhisycalSensor record, I want to set the Sensor records to that. Right now I handle this in my Serializer class: class PhysicalSensorSerializer(ModelSerializer): sensors = SensorSerialiazer(required=False, many=True) class Meta: fields = ("__all__") model = PhysicalSensor def create(self, validated_data): sensors = validated_data.pop("sensors") ph_sensor = super().create(validated_data) for sensor in sensors: s = Sensor.objects.get(sensor["id"]) s.physical_sensor = ph_sensor s.save() and for edit of PhysicalSensor, I use the same thing in .update() method of my Serializer. Is there any batter way of doing this or a best practice for this ? -
"'BillInvoice' instance needs to have a primary key value before this relationship can be used" Error

How to upload and store multiple images in Django 4
Django 4 Need user to be able to upload either an archive of images or just a few images at a time. Then these pages are numbered according to the order in which the user has placed them and stored in the database. Thus, when you open a page with images, there will be all the images just uploaded for this page in the correct order UPD: I would also be grateful if you could tell me how to rename files, change their extension, for example from .png to .jpg and in the path of saving in the model, for example, poster = models.ImageField(upload_to=‘posters/’, blank=False, null=False, verbose_name=‘Posters’) in the attribute upload_to add a value depending on what page the images are uploaded to. For example, if the page is called ‘opera’, the image path would be ‘posters/opera/1.jpg’, ‘opera/2.jpg’, etc. For the ‘Romeo and Juliet’ page it would be ‘posters/Romeo-and-Juliet/1.jpg.’ -

Data Flow in Django Rest Framework?
I have recently started learning Django Rest Framework, and hit a little roadblock trying to understand the data flow in DRF. From what I understand, views take in a web request and return a web response, so they are the first component in the DRF data flow right? (after the urls). Then what's the second step? Views generally refer to a serializer, so does our serializer get executed next. If so, why not our model because serializer is used to convert complex data types such as model instances into JSON. I have this and a couple of related questions after going through the DRF docs tutorial part-4. CONTEXT: In the docs we are creating code snippets and now we want to associate users with the snippets they created. We follow the steps below in the following order to achieve this: Below in the tutorial, we are creating a serializer to represent a user. How does a serializer help in representing a user, aren't serializers used to convert data? 1 Adding endpoints for our User models Now that we've got some users to work with, we'd better add representations of those users to our API. class UserSerializer(serializers.ModelSerializer): snippets = serializers.PrimaryKeyRelatedField(many=True, queryset=Snippet.objects.all()) … -
Django Model Form, seems like there is an anomaly where my user creation form's clean_username method is not throwing a ValidationError when it should
Background I have a custom User model that I have extended from BaseUserManager and AbstractBaseUser. Similarly, I have a custom sign-up form that I've extended from UserCreationForm (all these custom items are extended from django.contrib.auth). The custom UserCreationForm I've made has a method called clean_username() that checks for usernames that do not have any alpha-numerical characters (-@, --_, +@-_, etc.) and throws a ValidationError if that is the case (aside: the method also checks for usernames that, when slugified, would result in non-unique slugs). Problem When I test the aforementioned ValidationError, it still is somehow returning the form as valid, which causes the rest of my view's logic to run, which causes the User Model's clean() method to run, and in the User Model's clean() method, I have the same checks I have in the form's clean_username() method (for User's created without using this particular form). These checks throw a ValueError, which is not ideal because I need the form to be re-rendered with the proper ValidationError message so that users can fix what's wrong and still sign up. None of this makes sense. I've put print messages in my clean_username() method so that I know for sure the branch … -

Displaying images from static folder in Django

Mock patching an endpoint unittest that makes several requests to third party
I have a single endpoint written using django ninja. This endpoint executes a crawler that performs several requests. The sequence of requests has 3 different routines depending on whether or not the crawler already has valid login credentials in its session. I want to write e2e tests for these 3 routines and each of the possible exceptions that might be raised. The problem is there are up to 6 different requests in one sequence to a few different pages with a few different payloads. All I can think to do is patch each of these requests individually for each test but that is going to get ugly. My other thought is that I should just be satisfied with sufficient unit test coverage of the individual components of my crawler controller. Here is simplified code illustrating my issue api.py # This is what I want to test @api.get("/data/{data_id}") def get_data(request, data_id): controller = SearchController(crawler=Crawler, scraper=Scraper) response_data = controller.get_data(data_id) return api.create_response(request=request, data=response_data, status=200) # I have 5 of these right now and more to come @api.exception_handler(ChangePasswordError) def password_change_error_handler(request): data = { "error": "Failed to login", "message": "Provider is demanding a new password be set.", } return api.create_response(request=request, data=data, status=500) crawler.py Crawler(BaseAPI): def … -

django admin causing latency to load instances , the models have a related hierarcy
Case: I have relationships: 1 Distributor:M resellers, 1 reseller: M customers, 1customer: M domains, 1 Domain: M mailboxes. The model admin panel is taking a long time to load the objects for all the model admin. Does the default django return queryset return all the instances or load only that required in page 1 and then page2 on click etc. Why is there latency? Checked the pagination related document. But where does it say that all the objects in the queryset are retrieved at a time or only relevant to that page at a time? -
Django: How to use CURSOR .. WITH HOLD in Django ORM
In Django orm we have queryset.iterator https://docs.djangoproject.com/en/5.0/ref/models/querysets/#iterator that uses under the hood Postgres cursor www.postgresql.org/docs/current/sql-declare.html in case we using Postgres as a database of course. By default Django uses it with WITHOUT HOLD setting, which is default in Postgres, that why it is also default in Django. Question is - is it possibe to use django iterator() with WITH HOLD setting (not default) without switching to raw SQL somehow? Thank u
