How to call Dajngo render view from another APP render view template

This selector HTML have the drop-down boxes with the options for the user to choose nothing else than this. def selectionView(request, *args, **kwargs): return render(request, 'selector.html') Second view def dataView(request, *args, **kwargs): //code here to look into the database and then use the data in the HTML. //The filter will be taken from the dropdown box created in the above //selector.HTML FILE. return render(request,'tableContent.html', {'users': users}) My question here is there any way I can call the data view with values of dropdown box passed using JQuey or javascript or python from the first view. What I am looking for? Use the selection view as a landing page with the drop-down options and then use that dropdown option to call the data view and show the results. The records received are in thousands. Question? Is there any way I can do this like calling the render view from the HTML template of other Django view and passing the dropdown values as parameters to the view I want to call -
Running django tests in github actions causes Error code 137
I have an app made up of multiple containers that I run with docker-compose. I've tried adding a .yml file to my .github/workflows folder in order to run unit tests on every push to the repo. The containers start up fine but when it comes to the step for running the tests, there is an error: Error: Process completed with exit code 137. After looking up that exit code online, I found that this is a memory error but I can't figure out what is causing it and how to fix it.

Create subdomains like Shopify in pythonanywhere
My domain name is 'example.com' and I need to create subdomain for every store created in that site like 'store1.examaple.com', 'store2.examaple.com'. Code for every subdomain is the same. currently my project is deployed on pythonanywhere and I already have custom domain. So is it possible to dynamically create multiple subdomain in pythonanywhere same as Shopify ? -
Adding a transient ranking field to djangorest class and serializer
I am new to djangorest and am not sure how to even go about this. I have a Rest API that takes a post-request (with a list of parameters) and returns a list of items from a model via a serializer. It all works great. I need to add a "rank" or rather a "relevancy score" to the items in my returned list. I can calculate the rank fine - I am doing it in the REST view - what I don't understand is how to pass the rank back with the serialized model class in the response. I could create an entirely new object and pass it with the item ids.... but what I would rather do is attach a transient field: {"rank": value } to each item in my list. Can I do this? -
How to apply filtering after serialization with Filter backend in DRF?
For the context I will explain the current flow: The model Document has a field document_signing_status which has 2 possible values: SIGNED/NOT_SIGNED. However, in the serializer, I override this field by having a custom SerializerMethodField() which applies some modification and instead of returning 2 values it can return 4: "EXPIRED", "WAITING_FOR_ME", "WAITING_FOR_OTHERS", "SIGNED" I don't want to store these values on the database level, but I need to apply filtering. Right now I use filters.FilterSet, but it uses QuerySet so I can't simply specify filtering fields and pass "EXPIRED" since, in the model field there is only "SIGNED" or "NOT_SIGNED". How should I approach this issue? I thought about iterating the query set and applying modifications for that field to have one from possible 4 options, instead of 2, but not sure if it is a valid point and if even possible. -

I need to get an image from database (entered by me on Django-admin interface), and i need to display it in my pdf generated. I have first get the image for each specifc user logged in like that in the views.py: image1_full = CustomerPersonalData.objects.get(user_related=request.user) obj_image1 = CustomerPersonalData._meta.get_field('image1') value_image1 = str(obj_image1.value_from_object(image1_full)) in the pdf_generated.html, I have define it like that: <img src={{value_image1.url}} /> ----> but like that there is no image displayed.

Doubts about Django models primary_key and UniqueConstraint for composite primary key
Usually primary key means also unique (and more conditions like not null, etc.). If I have UniqueConstraint with 2 fields, including the primary key, I have 2 unique conditions (one because the primary key and another because the constraint). So that's is not the same than having a composite primary key with only one unique condition. For example, with this code: class MyClass (models.Model): field1=models.IntegerField(primary_key=True) field2=models.IntegerField() UniqueConstraint(fields=['field1', 'field2'], name='ConstraintName') Can I insert these values (1,1) and (1,2) since the field1 value is repeated and the primary key should be unique? In that case, what's the real meaning of primary key on Django models? Doesn't it imply a unique condition? Thanks a lot and regards. -
Adding frontend (Next.js/React) to django-oscar
I want to create an ecommerce app using django-oscar framework and self-build frontend. The docs explain how to change the website appearance but the base is build with bootstrap and standard django templates. To completely change storefront I just point at another folder in my project directory and create duplicated templates with the same name (for example if in framework there is product page then I need to create product_details.html template and code there). Now- I want to use Next.js (since React itself isn't great in terms of SEO) to build the storefront. What should be my approach? I don't know a lot of Next.js yet, in React I guess I would just generate .js file for every template (index.js for main page, product_details.js for products etc.). The REST API isn't a problem, there is django-oscar DRF version ready to use. -

Creating a game picking web app in django
I am having issues in writing code for my game picking app, I managed to get a model form working for admin game insertion to database (matchweek, game, result etc) but I am having trouble with writing a form and logic for user picks. I would like user to choose a week (I did this part) and then the form should have all games for that week, user and user picks. The logic is that you get one point for each game guessed right in a week, and than the user with most points gets 25 points for the summary point table. I am trying to get this gamepicking form working with formsets but I am not really sure anymore if my database logic is okay, I have a table called Bet containing user,game_id (FK) ,user pick. I am really stuck on this part. -

How to convert beforefilter from cakephp to Django?
I am moving website created in cakephp to Django rest framework. In cakephp, every controller has parent class as AppController. There is beforefilter in AppController which is checking authentication/permission and depending on permission other function is being called to set value of public variable present in that class. class AppController extends Controller { public temp1 = ''; public temp2 = array(); public function beforeFilter(){ } } I want to create it using Django Rest Framework and send json response to the react app. As far as login authentication is concerned, I used simple-jwt. class index(APIView): def get(self,request): data = {} return JsonResponse(data) Do I need to implement AppController in django separately, create function beforefilter() and call beforefilter() every time I create any api and What about checking whether user is authenticated or not ? Is there any simpler method to apply beforefilter? -
My unit tests don't work with multiple databases
I'm working on a project where there are two databases, and I need to create unit tests for my models and etc. these are my databases: DATABASES = { 'default': {}, 'auth_db': { 'NAME': 'name' 'ENGINE': 'django.db.backends.postgresql', 'USER': 'user' 'PASSWORD': 'password' 'PORT': 5432 'HOST': 'localhost }, 'base': { 'NAME': 'name, 'ENGINE': 'django.db.backends.postgresql', 'USER': 'user', 'PASSWORD': 'password', 'PORT': 5432, 'HOST': 'locahost, } } At first I'm creating only the unit tests of the models from django.test import TestCase from base.models import User class UserModelTest(TestCase): @classmethod def setUpTestData(cls): # Set up non-modified objects used by all test methods User.objects.create(first_name='Big', last_name='Bob') def test_first_name_label(self): author = User.objects.get(id=1) field_label = author._meta.get_field('first_name').verbose_name self.assertEqual(field_label, 'first name') But when I do sudo python3 manage.py test, it returns me the error: AssertionError: Database queries to 'base' are not allowed in this test. Add 'base' to base.tests.test_models.UserModelTest.databases to ensure proper test isolation and silence this failure. When I was working with just one database, it wasn't giving a problem, however, when I separated it, I had this problem. I've looked everywhere and haven't found a solution.
