List of string with Django and Django restAPI
I have setup my Django and Django restAPI and I'm trying to setup my model to have a list of strings. Here's my code model.py import uuid from django.db import models class TagModel(models.Model): name = models.CharField(max_length=100) class EventModel(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) title = models.CharField(max_length=255) tags = models.ManyToManyField(TagModel) class Meta: db_table = "events" ordering = ['-createdAt'] def __str__(self) -> str: return self.title serializers.py from rest_framework import serializers from .models import EventModel, TagModel class TagSerializer(serializers.ModelSerializer): class Meta: model = TagModel fields = '__all__' class EventSerializer(serializers.ModelSerializer): tags = TagSerializer(many=True) class Meta: model = EventModel fields = '__all__' My code works but not what I expected. I tried on postman to do a GET and POST request. The GET response seems to work well, but the POST request works but only with a dictionnary like the following { "title": "My example title", "tags": [{"name":"string"}, {"name":"pokemon"}] } but I wanna send something simpler like this { "title": "My example title", "tags": ["string", "pokemon"] } how to make this happen? Note: I don't use POSTGRESQL -
How do I unit test writing to a CSV file?
I am currently writing a test for a django script that writes some audit log entries to a CSV file. The system takes one CSV file, parses its contents, then adds entries based on the selections within, and saves it again once its all done. The outline of the test is as follows: class ProjectAuditReportExporterTestCase(TransactionTestCase): (...) def test_csv_generation(self): (...) mock_csv_writer = MagicMock() mock_csv_writer.writerow = MagicMock() with patch("external.exporters.csv_overwrite", return_value=mock_csv_writer) as mock_csv_overwrite: it = ImportTask.objects.create( organization=self.organization, user=self.user, data="force_delete", file=ContentFile(csv_buffer.getvalue(), "test_audit_report_exporter.csv"), importer="TasksAuditReportExporter", ) mock_csv_overwrite.assert_called_once_with(it.file, "Task Audit Report") mock_csv_writer.writerow.assert_called() The applicable bits of code for the export process are as follows: @contextmanager def csv_overwrite(file, filename_prefix) -> csv.writer: with tempfile.NamedTemporaryFile() as temp_file, io.TextIOWrapper( temp_file, encoding="utf-8-sig", write_through=True ) as text_file: yield csv.writer(text_file) temp_file.flush() temp_file.seek(0) file.save(f"{filename_prefix}_{now().strftime('%Y-%m-%d')}.csv", temp_file) (...) class EventsAuditReportExporter(BaseCSVImporter): def _handle_row(self, row): log_entries = self._logs_filter(LogEntry.objects.get_for_model(Event), start_date, end_date) with csv_overwrite(self.task.file, "Event Audit Report") as csv_writer: csv_writer.writerow( ( "Event ID", "Action date", "Action actor", "Action", "Event name", "Event date", ) ) for log_entry in log_entries.prefetch_related("actor", "version"): field_dict = log_entry.version.field_dict if field_dict: csv_writer.writerow( ( log_entry.object_id, log_entry.created.isoformat(), log_entry.actor, log_entry.action, field_dict.get("title"), field_dict.get("date"), ) ) I know there are appropriate log entries available, my debugger will always get into the csv_writer.writerow line with out issue. The issue that I have is that … -
Django: Extended User Model not saving changes to database
I have the following extended user class in models.py: Pro_User(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) access = models.BooleanField def access_update(self, Activated:bool): self.access = Activated self.save() However when I call access_update(True) in the shell it does not store the changes permanently, in the next shell session it is just BooleanField again.

Elasticsearch, Searching by extra field in logging
I'm using Elasticsearch with elastic-apm==6.19.0 configured for Django. After logging an error message like logger.exception( custom_logging_message, exc_info=True, extra={ 'status_code': status_code }, ) I can indeed observe the error containing custom_logging_message in Kibana. In Elasticsearch, I can even use Query DSL to view the document which was created by the above logging event. It also holds the data which was passed to the logger using the extra keyword, as follows: "error": { ..., "custom": { ..., "status_code": 500, } } So far so great, but I want to write a query which is based on one of the extra fields. Like: GET _search { "query": { "range": { "error.custom.status_code": { "gte": 500 } } } } But the result is empty. I tried to figure out whether the respective field is indexed, using the following query: GET _my_error_index/_mapping?pretty. The result did indeed not hold the respective field under "mappings". Is this the reason why I could not use it in the search query? And if so, how to I get it indexed? Is it a setting in the elastic-apm package? I am very new to this topic and appreciate any help. Thank you. -

How to get hierarchal results from models

What does the carat (^) operator do on Django Q objects?
The Django Query documentation mentions three operators which can be used to combine Q objects: Q objects can be combined using the &, |, and ^ operators. But the examples in the docs all focus on | (which is maybe understandable). The & and | operators are (to me at least) fairly obviously analogous to AND and OR. But what does ^ translate to in SQL? -

Rebalancing problem with Faust Streaming consumer
Hello everyone hope I find you well! I'm facing an odd situation when using Faust Streaming in my consumer app. So I have a Kafka Consumer that connects to my Kafka GCP instance on my dev environment in Google Cloud. However when sometimes my Kafka instance restarts or goes down to lack of resources when my consumer tries to rebalance it stays stuck in a loop with the following errors logging: [2023-12-20 10:23:47,912] [11] [INFO] Discovered coordinator 2 for group myapp-dev-processor [2023-12-20 10:23:47,912] [11] [INFO] (Re-)joining group myapp-dev-processor [2023-12-20 10:23:47,915] [11] [WARNING] Marking the coordinator dead (node 2)for group myapp-dev-processor. This is happening frequently for us only on our dev environment but we are investigating what may be the root cause of this issue and how to tackle it so that if it occurs in prod we have an way to act fast. We know the consumer connects to our kafka instance with success but then this error happens and it stays stuck in an endless loop. We tried search for any error log on our kafka instances but we don't find anything so we think this may be a problem within the library somehow. Does anyone have any idea … -

does pagination removed from coinbase wallet library in python?
I am using the Coinbase API to retrieve a list of accounts. According to the official documentation, I expected the response to include a pagination object alongside the data array. This pagination object is crucial for handling data systematically, especially when dealing with large datasets that require efficient navigation through multiple pages. Issue Encountered: However, in my recent interactions with the API, the responses lack the pagination object, and instead, only the data array is returned. This deviation from the documented response structure is causing significant issues in data handling and application functionality. Examples of Responses: Response from my Application: { "data": [ { "allow_deposits": true, "allow_withdrawals": true, "balance": { "amount": "0.00000000", "currency": "BIGTIME" }, "created_at": "2023-11-22T17:19:42Z", ... }, ... ] } Expected Response (Based on Documentation): { "pagination": { "ending_before": null, "starting_after": null, "limit": 25, "order": "desc", "previous_uri": null, "next_uri": null }, "data": [ { "id": "58542935-67b5-56e1-a3f9-42686e07fa40", "name": "My Vault", ... }, ... ] } Does any one have this issue or their is some issue with the old implementation?

Django form validation with foreign keys from two different tables
I have a question with forms validation for Django that I suspect is trivial but I am not Getting what I am missing as I am diving in django without too much understanding of some fundamental aspects and a bit confused by the documentation or issue here. This is not my code but a simplified version of the core problem: So my model would be something like: class Parent(models.Model): class Meta: ordering = ('name',) name = models.TextField(max_length=255, primary_key=True, unique=True) clothing= models.ManyToManyField(Clothing, through='childs') class Clothing(models.Model): class Meta: ordering = ('name',) name = models.TextField(max_length=255, primary_key=True, unique=True) class Childs(models.Model): class Meta: ordering = ('amount',) parent = models.ForeignKey(Parent, db_column='name', on_delete=models.CASCADE) clothing = models.ForeignKey(Clothing, db_column='name', on_delete=models.CASCADE) amount = models.DecimalField(max_digits=5, decimal_places=0) class FamilyDressing(forms.ModelForm): class Meta: model = Childs fields = ('parent', 'clothing', 'amount') which hopefully is right. Lets imagine a way of uploading a csv file with a list of children, their associated parent and associated piece of cloth. To validate such form I thought I first can validate the Clothing model, that seems to work, then validate the childs model with the parent name, piece of cloth and amount but somehow I can only validate parent and amount together but not the three fields at … -

Unable to replicate existing Svelte/Django SPA approach in migration to SvelteKit
I have a Svelte 3 SPA that sits in front of a Django API. Currently, it compiles the prod release into the static folder used by Django. The SPA is served by a Django template to let it take care of auth. Svelte is configured to use consistent names for the compiled artefacts: The Django template to show the svelte app is basically an empty page that links in the SPA: <link rel='stylesheet' href={% static 'svelte/build/bundle.css' %}> <link rel='stylesheet' href={% static 'svelte/build/vendor.css' %}> <script defer src={% static 'svelte/build/bundle.js' %}></script> Django is setup to handle a couple of URL paths and then pass anything else through to the svelte template. Because it's a Django template, if the user hasn't auth'd when viewing it it takes them through the login process first, then back to the app. This has been working great and has been easy to deploy & explain to others. I'm currently migrating to SvelteKit 2 before a handover (mostly due to the prominence of SK docs over vanilla svelte). I'm following the now recommended approach for SPAs and using adapter-static to produce the build artefacts. With the way the app currently authenticates, I can't fall through at the web … -
Return multiple values in Django Class-based View
I am working on a project for a Django course I am taking but currently struggling a bit with views. In the project I created a View using ListView to display a list of products in my template. By using query_set I am able to get all the objects and return them to display all the products and their attributes in the template by using a for loop. In the same query_set, I tried returning another variable that contains the total items in stock to display this data in the template as well, however, as soon as I add this variable to the return the template no longer receives the returned values. This is the code I tried to return both values: class ShopListing(ListView): template_name = "webshop/shop_listing.html" context_object_name = 'shop_listing' def get_queryset(self): #Get all products products = Product.objects.all() total_stock = products.aggregate(sum=Sum('stock'))['sum'] return products, total_stock In my template I added the value 'total_stock' as shown below but I get nothing, and even the values from 'products' stop working: <strong>{{total_stock}}</strong> items are currently available</p> If I remove 'total_stock' from the return everything goes back to normal.

Using JWT from frontend MSAL to authenticate backend REST API (Django REST Framework, react.js)
My scenario is I have an existing frontend react project that authenticates with SSO using MSAL. This results in the frontend having a JWT token in it's session storage that contains the relevant signed information about the user. I need to create a backend REST API in Django that will be the backend to the react project. My question is: can I send the JWT token to the backend, check for a valid signature, and if it is valid use it to create a user in the database associated with that email? I'm not the most familiar with authentication methods and I'm struggling to find documentation that matches my use case. Although in my particular use case I'm implementing this in Django and React, my question is more on is this authentication method okay from a theoretical perspective? Any advice is appreciated.
