coverage won't test the whole files test coverage right?
I'm trying to understand if we we have lot of services file written in the Djano project. We're writing the tests using pytest framework. I have a question related to this command coverage run -m pytest && coverage report && coverage xml So the coverage will not show all the files which has not test cases it will just show the file you have written the test for and how much you have written(in percentage)? is my understanding correct? Can we see somehow for all the files it hasn't covered yet. I tried running the command but its only showing me for one file can someone explain me here -

what is React py and in how much time it will be stable?
React.py is a Python library that enables developers to build web applications using the principles and concepts of React, a popular JavaScript library for building user interfaces. React.py allows developers who are more comfortable with Python to leverage the benefits of React without having to write JavaScript code. At the time of my knowledge cutoff in September 2021, React.py was not a widely recognized or established library in the Python ecosystem. It is important to note that the development of open-source libraries and frameworks can be unpredictable, and it is difficult to determine an exact timeline for when a particular library will reach a stable version. However, typically, the stability of a library depends on factors such as community adoption, active maintenance, and the resolution of any reported issues or bugs. Therefore, it is advisable to check the latest updates and releases from the React.py community to assess the current status and stability of the library. Regarding the differences between React.py and React.js, the key distinction lies in the programming language used. React.js is primarily used with JavaScript, while React.py enables the use of Python for building web applications with React concepts. While React.js has a large and established ecosystem, … -

Managing User Authentication Across Multiple Django Projects with a Custom User Model
I have three Django projects: Project A, Project B, and Project C. Project A serves as the authentication project, Project B is responsible for managing user-related functionalities, and Project C handles restaurant-related operations. In Project A, I have created a custom user model to suit my authentication requirements. Now, I want to utilize this custom user model to access the APIs of both Project B and Project C. How can I achieve this integration between the projects? Specifically, I would like to accomplish the following: Enable user authentication: I want to use the custom user model defined in Project A to authenticate users when they access the APIs of Project B and Project C. Share user information: I need to access user information from Project B and Project C using the custom user model defined in Project A. This includes retrieving user details, updating user profiles, and performing user-related operations. Maintain consistency: It is essential to ensure that any changes made to the custom user model in Project A are reflected across all projects, including Project B and Project C. Here is my Custom user Model from Project A. import uuid from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin from django.db import … -

How to parse value from key in django template
First i want to explain what i want to achieve. at first this my query at view invoices = vendor.invoices.order_by('-due_date') this is the relevant model : class Booking(model.Models): ... invoice = models.ForeignKey('invoices.Invoice', related_name="bookings", on_delete=models.CASCADE, blank=True, null=True) POD_RETURN_STATUS = Choices( (1, 'on_driver', 'On Driver'), (2, 'taken_by_recipient', 'Taken by Recipient'), ... ) pod_return_status = models.PositiveSmallIntegerField(choices=POD_RETURN_STATUS, blank=True, null=True) whats new is i want to add the pod_return_status in template using invoice query. So like {% for invoice in invoices %} ... <td>{{ invoice.bookings.first.pod_return_status }}</td> {% endfor %} but of course it increases the number of query. at first i use prefetch_related but it seems to added more query. So after consulting with chatGPT this is my updated_query: invoices = vendor.invoices.order_by('-due_date').annotate( pod_return_status=Subquery( Booking.objects.filter(vendor_invoice=OuterRef('pk')).values('pod_return_status')[:1] ) ) it looks good on query numbers, but when i want to parse in template like this <td>{{ invoice.pod_return_status }}</td> it display the number like 1,2. what i want to display is the value of it like, 'On Driver' etc. Since im using model_utils.Choice, usually to display in template i use booking.get_field_name_display. but since the pod_return_status is acquired from annotation, not from the parents model. i cant use that. what im trying is to parse "POD_RETURN_STATUS": Booking.POD_RETURN_STATUS, to context_data so … -

Issue with combining data from multiple Django apps into a single form option in admin back office
I'm a fairly novice developer, but I'm aiming to master Django by developing a multi-tenant SaaS application that lets users create their own online stores. I'm still at the beginning of the project, but I've already run into a problem that's blocking me. My aim is to offer basic categories common to all users, while allowing them to create their own customized categories to classify their products. To achieve this, I've set up a multi-tenant architecture with Django-tenants, where each user has his own subdomain, store and categories. However, I'm having trouble grouping shared and custom categories in the user administration interface form, just where they can add a product (and choose the related category). I want users to be able to choose the category of their products from a list that includes both, shared categories and their own custom categories. I've tried several approaches, including the use of ManyToMany fields and custom widgets, but so far I haven't managed to get the desired result. Shared categories are not properly integrated into the category selection field, which limits the functionality of my application. If you have any suggestions, ideas or pointers on how best to solve this problem and group … -

How do I calculate the total number of likes for a user's posts in Django?
I'm working on a Django project and I'm trying to calculate the total number of likes for a user based on their posts (i.e if a user has post with 10 likes and another with 5, the total likes must display 15) .

Django DRF Serializer slice amount in list of nested field based on user

Django strange static behavior
I launched the small Polls app from Django tutorial here: https://docs.djangoproject.com/en/4.1/intro/tutorial06/ The first time i wrote it, all worked fine. Then I tried to add the same style to all other html files in the same dir as index.html: results.hmtl, votes.html and detail.html and then the strangest thing happened. No styles were added to these files also when i tried to change the style of polls/static/polls/style.css , nothing happened. I even renamed the style.css and the styles added to index.html remained unchanged. This means django looks for styles elsewhere. So where is this place? My settings are standard: settings.py: STATIC_URL = 'static/' STATIC_ROOT = "" index.html: {% load static %} <link rel="stylesheet" href="{% static 'polls/style.css' %}"> urls.py: from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('polls/', include('polls.urls')), path('', include('polls.urls')), path('admin/', admin.site.urls) ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) No effect whatsoeveer. I read the documentation, read comments here, nothing flashes, so I'm asking here, hoping for a chance to repair my static. Thanks! -
Integrating Firebase authentication with Django (DRF)
I am developing a Django (DRF)/React web application and have integrated Firebase authentication using the email/password provider. The application requires additional user data, and I aim to link the Firebase user database with the Django user model. The primary objective is to implement a secure and efficient authentication system. Workflow: Web client: Users sign up with their email and password, followed by the receipt of a verification email. Web client: Retrieve the ID token and send it, along with extra user data (e.g., first name, last name, organization, role), to the server. Server: Verify the ID token and authenticate the request using the FirebaseAuthentication class. Server: Check if the user exists in the Firebase database. Server: Create a user record in the Django user model if the user exists, ensuring data consistency between Firebase and Django. I have implemented a Django authentication backend using the FirebaseAuthentication class, as shown below: default_app = initialize_app() class FirebaseAuthentication(BaseAuthentication): def authenticate(self, request): auth_header = request.META.get("HTTP_AUTHORIZATION") if not auth_header: raise NoAuthToken("No auth token provided") id_token = auth_header.split(" ").pop() decoded_token = None try: decoded_token = auth.verify_id_token(id_token) except Exception: raise InvalidAuthToken("Invalid auth token") if not id_token or not decoded_token: return None try: uid = decoded_token.get("uid") except Exception: … -
