🚀 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.

📝 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.

📝 Add an option to rename schemas (#505)


Right now schemas are registered like regular python classes, their name is just type(...).__name__ we need a way to rename schemas in the openapi.

I propose adding __dmr_schema_name__ special attribute to do that.

This will also require a test case for the openapi.

📝 Remove `WPS354` (#3601)


This rules has more problems that it solves:

1. Two yields and yield from are two different things
2. Async iterators cannot use yield from, but WPS354 still raises even in async def

So, it is time to remove this rule. I was wrong about that :(
See other rules with disabled_since attribute on how to disable a rule.

📝 Bug: AsyncAPI documentation fails when Confluent uses oauth bearer authentication (#2774)


Describe the bug
When using Confluent Kafka with oauthbearer authentication, the generated AsyncAPI schema is:

 "securitySchemes":{"oauthbearer":{"type":"oauth2","$ref":""}}

An empty $ref: "" causes the AsyncAPI React component to attempt file resolution via readFile. This is a FastStream bug in schema generation.

How to reproduce
Include source code:

from faststream.confluent import KafkaBroker

broker = KafkaBroker(
config={ ...config... },
security=SASLOAuthBearer(use_ssl=True)
)
...

Expected behavior
AsyncAPI documentation is correctly generated.

Observed behavior
It fails with a file cannot be read error.

Screenshots
If applicable, attach screenshots to help illustrate the problem.

Environment
Running FastStream 0.6.5 with CPython 3.13.11 on Darwin

📝 Improving XML processing in `XMLParser` for correct validation of Pydantic models (#541)


The current implementation of XMLParser in django_test_app (and the example in the documentation) leads to massive validation errors (400 Bad Request) during automated testing via Schemathesis. The problem is caused by two factors:

1. Extra nesting (Root Element): xmltodict.parse always returns a dictionary where the data is nested in the key corresponding to the name of the root tag. Pydantic models (for example, _RequestModel) expects the data to be "flat", which is why validation crashes with the field required error for all fields, since they are wrapped in the tag name.
2. Type mismatch for empty tags: XML does not have built-in types. Empty tags () are parsed by xmltodict as None. If the Pydantic model expects str, it causes an error validation, although in the context of XML, an empty tag is often equivalent to an empty string.

Most likely, this bug ( #499 ) is related to this, but the problem may be complex.

📝 Add `auth=` parameter to `sse()` function (#546)


I forgot to add auth= to parameters of

django-modern-rest/dmr/sse/builder.py

Lines 63 to 79 in 8866e4c

This is totally required. Docs and tests are also required :)

📝 `WPS457` false positive with `while` in `try` / `except` (#3603)


I have the following code:

def factory() -> Iterator[bytes]:
try:
while True: # noqa: WPS457
yield async_to_sync(async_anext)(iterator)
except StopAsyncIteration:
pass

It should not raise WPS457, because while is in try / except.
It can clearly raise and we handle the error. So, it is not infinite.

PRs are welcome! 👍

📝 Feature: Static membership for aiokafka broker (group_instance_id) (#2782)


Hi!

Seems like aiokafka broker missing group_instance_id argument which required for static membership to work.

https://aiokafka.readthedocs.io/en/stable/api.html

group_instance_id (str or None) – name of the group instance ID used for static membership (KIP-345)

For confluent kafka it exists #2606

📝 Support `etag` (#572)


Docs: https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/ETag
Implementation example: https://docs.litestar.dev/latest/usage/responses.html#etag

We already can set etag as a header in @modify with NewHeader.
What do we need exactly?

1. We need ETag dataclass to represent the parsed header. It should also know how to unparse itself into a header
2. We need docs about sending ETag header and getting header If-Match back

📝 Add `Settings.semantic_responses` flag (#589)


Users might not need our semantic responses at all. It needs a kill switch.

We need to add Settings.semantic_responses flag, which should be True by default.
If set to False, we should not add any extra response specs to the final metadata.

Probably, we should add if check for this in EndpointMetadata.response_spec_providers

This would need several tests:

1. Snapshot test for the resulting OpenAPI spec
2. Test that response validation would still be required, missing responses must raise 419

Also, this would require docs in configuration.rst

📝 Add 3 more tests for component schema generation (#603)


There are several cases that we don't cover in tests/test_unit/test_openapi/test_schema_snapshots.py

1. We need to test Query component schema generation with one field in __dmr_force_list__ and one other regular field

 django-modern-rest/tests/test_unit/test_openapi/test_schema_snapshots.py

 Line 66 in 8555cd5

2. We need to test Query component with at least one field in

 django-modern-rest/tests/test_unit/test_openapi/test_schema_snapshots.py

 Line 67 in 8555cd5

These corner cases can just be added to the existing _QueryModel

1. We also need to test at least one file field as a list, add one field to __dmr_force_list__ for FileMetadata component as well

 django-modern-rest/tests/test_unit/test_openapi/test_schema_snapshots.py

 Line 122 in 8555cd5

This can be added to _SeveralFiles model.

This is a super easy issue for first-timers only :)

📝 Make an `@overload`ed function from `load_schema` (#625)


Currently load_schema can accept just a single argument if should_generate_examples is False.
Otherwise it needs extra params:

django-modern-rest/dmr/openapi/mappers/schema_loader.py

Lines 21 to 28 in 6c06cd9

This needs to be an overload.
This is a very easy task :)

We will only provide en-us translation for now. Later more can be added if needed.

📝 Formalize our CDN / static files support for OpenAPI renderers (#678)


I think that we should be able to configure: do we want to use local static files, served by django for OpenAPI renderers and interactive APIs, or should we use CDN for this.

Currently:

• Swagger uses local static files
• Scalar / Redoc use CDNs

Plan:

1. Introduce openapi_static_cdn: {'scalar': 'https://cdn_url.com'} option, where we can specify when these libs should use CDN
2. Only when some lib has this explicit setting, we should use the CDN. Otherwise, they should use local static files which should be copied to dmr
3. We need to document the EXACT versions we have bundleded in our static files
4. We need to copy their licenses as well, not just static files. Because we take their code / build result. They can go to our LICENSE.md at the very bottom, specify why it is there

📝 Make an `@overload` from `SchemaGenerator.__call__` (#679)


This code right now is not ideal:

django-modern-rest/dmr/openapi/generators/schema.py

Lines 22 to 31 in 8917dd3

Because when skip_registration=True, we know that we return a Schema object only.
While it is skip_registration=False we can return Schema | Reference.

This needs to be an @overloaded function with correct return types.
This is a very easy task for first-timers only :)
