🚀 New issue to wemake-services/django-modern-rest by @kondratevdev 📝 Enable `positive_data_acceptance` in `schemathesis` (#496) At the moment, this check is disabled in the configuration. We need to enable it (delete the line, because by default we have everything enabled) and fix the error that this check catches. #enhancement #help_wanted #django_modern_rest sent via relator

🚀 New issue to wemake-services/wemake-python-styleguide by @sobolevn 📝 `WPS617` false positive with keyword args (#3596)

self._media_by_precedence = sorted(
    (
        media_type
        for parser in self._parsers.values()
        if (media_type := MediaType(parser.content_type)).quality != 0
    ),
    key=lambda media: (media.specificity, media.quality),  # noqa: WPS617
    reverse=True,
)

It says:

django_modern_rest/negotiation.py

  52:17    WPS617 Found lambda assigned as an attribute
  key=lambda media: (media.specificity, media.quality),
      ^

Which is clearly a bug, it is a named param, not an attribute. PRs are welcome, this is easy to fix. #bug #help_wanted #levelstarter #good_first_issue #wemake_python_styleguide #wps sent via relator

🚀 New issue to wemake-services/django-modern-rest by @sobolevn 📝 Add unit tests for pagination (#484) Right now we only test pagination in the doctests: https://github.com/wemake-services/django-modern-rest/blob/master/docs/examples/integrations/pagination.py Let's add the same test to test_unit as well. Create new test_pagination folder and put it there. This is a very easy task for entry-level controbutors :) #enhancement #good_first_issue #help_wanted #django_modern_rest sent via relator

🚀 New issue to wemake-services/django-modern-rest by @sobolevn 📝 Add `cookies` support to `APIError` (#465) Right now we support cookies in our API: django-modern-rest/django_modern_rest/response.py Lines 78 to 85 in ddfe907 But, APIError does not allow to set any cookies: django-modern-rest/django_modern_rest/response.py Lines 64 to 75 in ddfe907 This is unfortunate. We need to be able to do anything we can do with a regular response with APIError.

🚀 New issue to wemake-services/django-modern-rest by @sobolevn 📝 JWT token blacklist app: design conditional apps (#462) We need to design how we can add conditional django apps that have models to the framework. For example, right now we can add an app to blacklist some jwt tokens. What's interesting about that? 1. We need to design this app in a way that it is not required by default, with no visible parts 2. We need to design it that it will be very easy to install and use. For example: it should provide a mixin class that can be used together with JWTSyncAuth / JWTAsyncAuth and a pre-existing common subclass So, usage will look something like:

from django_modern_rest.some.place.for.app.models import BlacklistedJWTToken

class BlacklistMixin:
     def check_auth(self, user: 'AbstractBaseUser', token: JWTToken) -> None:
        super().check_user()
        if BlacklistedJWTToken.objects.filter(jti=token.jti).exists():
            # Token was blacklisted:
            raise NotAuthenticatedError

We use jti to identify tokens, as other jwt's do. It is now possible after #461 Sources of inspiration: • https://github.com/jazzband/djangorestframework-simplejwt/blob/master/rest_framework_simplejwt/token_blacklist/models.py • https://django-rest-framework-simplejwt.readthedocs.io/en/latest/blacklist_app.html #enhancement #good_first_issue #help_wanted #django_modern_rest sent via relator

🚀 New issue to wemake-services/django-modern-rest by @sobolevn 📝 Add `:language: python` to every single `.. literalinclude` (#458) Sometimes without :language: python sphinx does not render code correctly. Example: 🖼️Image This happens because .. literalinclude there does not have :language: python django-modern-rest/docs/pages/using-controller.rst Lines 171 to 178 in d654770 We need to add it everywhere, where it is missing. #documentation #good_first_issue #help_wanted #django_modern_rest sent via relator

🚀 New issue to wemake-services/django-modern-rest by @sobolevn 📝 Support conditional parsing in components (#453) Right now we support conditional return types: django-modern-rest/django_modern_rest/negotiation.py Lines 212 to 228 in 35051cd But, incomming Body / Headers / Query can also be conditional, depending on the content-type. Should we reuse the same feature for parsing? OpenAPI fully supports this feature:

      requestBody:
        description: Optional description in *Markdown*
        required: true
        content:
          application/json:
            schema:
              $ref: "#/components/schemas/Pet"
          application/xml:
            schema:
              $ref: "#/components/schemas/Pet"

For people who want to solve this: this is not easy! Here's how the process should look like: 1. You present the idea and prototype implementation 2. We iterate on the design (several times maybe) 3. I approve the design 4. We can then continue with the implementation :) #enhancement #help_wanted #django_modern_rest sent via relator

This code falsy raises two WPS430 violations.

  84:9     WPS430 Found nested function: factory

But, the name is correct. decorator name is in whitelist of names. This is a false positive. We need to fix it and add a test case. #bug #help_wanted #levelstarter #good_first_issue #wemake_python_styleguide #wps sent via relator

🚀 New issue to wemake-services/django-modern-rest by @sobolevn 📝 Fix `Sequence[SyncAuth | AsyncAuth]` to be `Sequence[SyncAuth] | Sequence[AsyncAuth]` (#408) I've made a mistake in modify and validate typing: django-modern-rest/django_modern_rest/endpoint.py Line 411 in 65d7638 I used Sequence[SyncAuth | AsyncAuth] instead of Sequence[SyncAuth] | Sequence[AsyncAuth]. Here's the difference: https://mypy-play.net/?mypy=latest&python=3.12&flags=strict&gist=487fad8c5bdaa2e7d2b4e84a3fa25a6d We need to fix the typings of @modify and @validate and add a typesafety/ test that providing both sync and async auth at the same time is a type error.

🚀 New issue to wemake-services/django-modern-rest by @sobolevn 📝 Negotiate response renderer as soon as possible (#402) I think that it would be fair not to do anything if we can't find a renderer for the response. It is better than we do it right now, when we finish all the business logic, just to find out that we can't show a proper response. We should move response_negotiator call before the actual endpoint execution. Maybe here? django-modern-rest/django_modern_rest/endpoint.py Lines 148 to 150 in 697c348 We should also add a test case that endpoint logic is not executed if there's something wrong with the negotiation. #enhancement #good_first_issue #help_wanted #django_modern_rest sent via relator

🚀 New issue to wemake-services/django-modern-rest by @sobolevn 📝 Test that `HttpResponseRedirect` works and provide `APIRedirect` exception (#107) We have a TODO item for redirects: django-modern-rest/django_modern_rest/controller.py Line 187 in be877dc DRF uses regular HttpResonseRedirect and it seems to work well. We need to test that we also can return HttpResponseRedirect in @validate endpoints. In @modify endpoints we should better provide a helper called APIRedirect which should be a subclass of APIError with location field. See the original implementation of HttpRedirectResponse here https://github.com/django/django/blob/ca3e0484ef31d13053af6a9d50667813e22fc282/django/http/response.py#L628-L653 Make sure that preserve_request also works. @Peopl3s are you interested?

🚀 New issue to wemake-services/wemake-python-styleguide by @luminoso 📝 False positive for WPS457 when using asyncio to control loops (#3573) What's wrong For the code:

import asyncio


async def infinite_loop() -> None:
    try:
        while True:
            await asyncio.sleep(1)
            print("I'm alive. And doing work.")
    except asyncio.CancelledError:
        print("Loop cancelled")


t = asyncio.create_task(infinite_loop())
await asyncio.sleep(5)
t.cancel()

WPS457: Found an infinite while loop is raised. But infinite loop is being handled. Just not within the while loop. How it should be Not to raise WPS457. Not 100% sure here if it is the best practice or not. Also probably the solution is too complex and is just easier to add a noqa in the code. Flake8 version and plugins
