Django Session Auth and DRF Knox JWT
I have an API from which users can login to get a token so they can make requests, etc and I have also made a a session login as there are a few scenarios where I need the user session token. Now if a user logs in to the API and afterwards they need to login using the session Auth its all good however the reverse does not work. If you are logged in using session Auth and then want to login via the API to release a token I get a response of Forbidden. Could someone please offer some insight? -

How to implement a verification system? Django
The task is to implement a verification system for the following actions: registration, password reset, change of email address, change of phone number. What do I mean by this task? Need to generate tokens and then send them to user email address or phone number. After using them, user will be verified. For myself, I have identified a bunch of options, but I don’t know which one to choose. Generate the same type of token for SMS and email. This token is a code, six-digit, for example. Store them in redis, where the key is the user id and the value is the token itself. When the code comes from the client, search for it in redis. If it does not exist, then it is possible that it expired, or it did not exist at all. Store codes in the Django model, delete expired ones on access and make a management command so that we can delete those that have not been accessed. Generate only digital codes for SMS, and character tokens for email. It is possible that there is no best option at all among those listed. Please tell me the best practices. I am interested in what method … -
Problem with testing custom admin actions
Running into some problems when testing my custom admin actions. First I can show you an example of a test that works and the actions it's testing. custom action, Product model @admin.action(description="Merge selected products") def merge_products(self, request, queryset): list_of_products = queryset.order_by("created_at") list_of_products = list(list_of_products) canonical_product = list_of_products[0] list_of_products.remove(canonical_product) for p in list_of_products: for ep in p.external_products.all(): ep.internal_product = canonical_product ep.save() p.save() canonical_product.save() related test class MockRequest(object): pass class ProductAdminTest(TestCase): def setUp(self): self.product_admin = ProductAdmin(model=Product, admin_site=AdminSite()) User = get_user_model() admin_user = User.objects.create_superuser( username="superadmin", email="superadmin@email.com", password="testpass123" ) self.client.force_login(admin_user) def test_product_merge(self): self.boot1 = baker.make("products.Product", title="Filippa K boots", id=uuid4()) self.boot2 = baker.make("products.Product", title="Filippa K boots", id=uuid4()) self.external_product1 = baker.make( "external_products.ExternalProduct", internal_product=self.boot1 ) self.external_product2 = baker.make( "external_products.ExternalProduct", internal_product=self.boot2 ) self.assertEqual(self.boot1.external_products.count(), 1) self.assertEqual(self.boot2.external_products.count(), 1) request = MockRequest() queryset = Product.objects.filter(title="Filippa K boots") self.product_admin.merge_products(request, queryset) self.assertEqual(self.boot1.external_products.count(), 2) self.assertEqual(self.boot2.external_products.count(), 0) Might not be the pretties test but it works, so does the action. The code above works as it should but has been running into problems when trying to test an almost identical action but for another model. custom action, Brand model @admin.action(description="Merge selected brands") def merge_brands(self, request, queryset): qs_of_brands = queryset.order_by("created_at") list_of_brands = list(qs_of_brands) canonical_brand = list_of_brands[0] for brand in list_of_brands: if brand.canonical: canonical_brand = brand list_of_brands.remove(canonical_brand) … -
Trouble in setting only one serializer field to read_only Django Rest Framework
I have this model serializer and it has a lot of fields I want to use fields="__all__" but still be able to set one field to read_only = True. I tried having it like this: class InstitutionSerializer(serializers.ModelSerializer): class Meta: model = Institution fields = "__all__" def __init__(self, *args, **kwargs): super(InstitutionSerializer, self).__init__(*args, **kwargs) for field in self.fields: if field == "owner": self.fields[field].read_only = True But it still flags "owner": ["This field is required."] which is unneccessary for me because I want it to be able to set it on my view. I also tried extra_kwargs = {"owner": {"read_only": True}} and read_only_fields = ("owner",) but still fails. -
clean() method in Django ModelForm to avoid duplicate entries creates another instance upon updating the data. And doesn't even save a new instance

Django form is not being valid, how to fix it?

How do I JSON parse a Django queryset?
So I'm trying to parse each object in my Django queryset, and deal with the data through JavaScript. Below is my code (simplified) : views.py (using Django Paginator, but the basic idea is the same.) def main_page(request): all_contents = Contents.objects.all() paginator_contents = Paginator(contents,10) page = request.GET.get('page') all_contents_paginated = paginator_contents.get_page(page) context = { 'contents' : contents, 'all_contents_paginated' : all_contents_paginated } return render(request, 'main/home.html', context) template {% for c in all_contents_paginated %} <div class="text-m"> {{c.author}} </div> <div class="text-s" onclick="DetailModal('{{c}}')"> {{c.body}} </div> {% endfor %} <script> function DetailModal(c) { } </script> Now obviously, the '{{c}}' cannot be parsed into JSON since it's string. I want to parse it into JSON in function DetailModal() and display the data in a separate modal element or do any other stuff with each data. But I can't figure out how to parse each object in the Django queryset. Any ideas? Thanks. -
Fill out Django form with data obtained from URL
I want to create a new Fallacy (see models.py) via the form to which I get over the url path('<slug:slug_tree>/new/', views.CreateFallacyView.as_view(), name='create_fallacy'),. So the user is on the TreeDetailView (which corresponds to a certain Tree), and he can add a new Fallacy to this tree. The user should input title and detail, but the Tree (ForeignKey) should be assigned in the code. It should be assigned to the corresponding Tree from which he was directed to the CreateFallacyView. The slug of the tree is inside the URL, so I thought I could use that information somehow, but I have no idea how I can proceed with that information. Any help is appreciated! Or probably there are other more elegant solutions? Many thanks! models.py class Tree(models.Model): title = models.CharField(max_length=50) detail = models.TextField() slug = models.SlugField(allow_unicode=True, unique=True, null=True, blank=True) class Fallacy(models.Model): title = models.CharField(max_length=50) detail = models.TextField() tree = models.ForeignKey(Tree, related_name='fallacy', on_delete=models.CASCADE) views.py class CreateFallacyView(generic.CreateView): form_class = forms.FallacyForm forms.py class FallacyForm(forms.ModelForm): class Meta: model = models.Fallacy fields = ('title', 'detail') urls.py app_name = 'argtree' urlpatterns = [ path('', views.TreeListView.as_view(), name='all'), path('<slug:slug_tree>/', views.TreeDetailView.as_view(), name='tree_detail'), path('<slug:slug_tree>/new/', views.CreateFallacyView.as_view(), name='create_fallacy'), -

django get_queryset() with conditional filter()
I have a custom model manager on model such as: class MyCustomManager(models.Manager): def doFoo(self, user, s_format): qs = super().get_queryset().filter(created_by=user) return qs which is returning data based on the user passed as the argument. However, how would I go about adding more AND conditions to the above query based on if conditions? Something like this: class MyCustomManager(models.Manager): def doFoo(self, user, s_format): qs = super().get_queryset().filter(created_by=user) if <condition 1>: qs.filter(mode='A') elif <condition 2>: qs.filter(mode='B') return qs If I do the above, even if <condition 2> is true, it's not generating created_by=1 AND mode='B' SQL I'm basically trying to do the equivalent of the following but split by conditions qs = super().get_queryset().filter(created_by=user, mode='A') -
How to configure celery for concurrent execution with multi process?
I have a task that talks to an external API, the json response is quite large and I have to make this call multiple times followed by further python processing.

Python/Django - How to check url endpoint with an attached JWT?
I need to connect to a server from my Django application (Connection Test). The problem is that the server I'm trying to connect to only returns http_200 if an attached JWT token at the Authorization Header is given. How can I attach a JWT to a request I send from my application? Currently, I generate the JWT for the test connection like so: user = self.context['request'].user jwt_payload = jwt_payload_handler(user) access_token = str("Bearer " + jwt_encode_handler(jwt_payload)) Thanks in advance -

I checked <project folder>/media/images/user_6badb4b8-33ba-4bb9-aa9a-2e3afb359960/7afbaf6f-67ef-4879-bd61-026cc947933b.jpg and the file I'm trying to render is definitely there. Why is React Native not rendering the image URL? -

How do I make a POST request using axios in react?
I am having issues with the axios post request. When I click on the Button, nothing happens. What is supposed to happen is that the data that I enter into the input fields is submitted to the API. However, no redirect or anything happens when I click the Button. I am not sure whether the onClick function in the Button is never being triggered or whether the issue lies with the call of axios and then the useNavigate function. I have tried several different ways of using these function but none worked. It might be a syntactic issue as I am a beginner with react. Any help would be appreciated! Full Code: import axios from 'axios'; import React, { useState } from 'react'; import { Container, Button } from 'react-bootstrap'; import { useNavigate } from 'react-router-dom'; const AddContact = () => { const [first_name, setFirstName] = useState("") const [last_name, setLastName] = useState("") const [mobile_number, setMobileNumber] = useState("") const [home_number, setHomeNumber] = useState("") const [work_number, setWorkNumber] = useState("") const [email_address, setEmailAddress] = useState("") const history = useNavigate(); const AddContactInfo = async () => { let formField = new FormData(); formField.append('first_name', first_name) formField.append('last_name', last_name) formField.append('mobile_number', mobile_number) formField.append('home_number', home_number) formField.append('work_number', work_number) formField.append('email_address', email_address) …
