📝 Bug: Logger not properly passed to Confluent Kafka Producer and AdminClient (#2691)


Describe the bug

There are two related issues with logger configuration in the Confluent Kafka components:

1.

 Late Logger Setup in AsyncConfluentProducer

 In faststream/confluent/helpers/client.py at line 46, the Producer object is created before the _setup() method is called for loger_state. This results in the Producer receiving a NoSetLoggerObject instead of the intended logger passed during initialization.

2.

 Missing Logger in AdminClient
 The AdminClient in AdminService does not accept a logger parameter, even though it should. Currently, only the configuration is passed, leaving the AdminClient without proper logging.

How to reproduce
Include source code:

import logging

import uvicorn
from fastapi import FastAPI
from faststream.confluent.fastapi import KafkaRouter

logger = logging.getLogger("faststream")

router = KafkaRouter(
    bootstrap_servers="kafka:9092",
    enable_idempotence=True,
    allow_auto_create_topics=False,
    schema_url="/asyncapi",
    include_in_schema=True,
    logger=logger,
)

app = FastAPI()
app.include_router(router)

uvicorn.run(app, host="0.0.0.0", port=8000)

Expected behavior

1. The Producer in AsyncConfluentProducer should use the logger passed to KafkaRouter.
2. The AdminClient should inherit the same logger as other components.

Observed behavior

1. The Producer uses NoSetLoggerObject instead of the provided logger.
2. The AdminClient lacks logger configuration, leading to potential silent failures or inadequate logging.

Environment
Running FastStream 0.6.3 with CPython 3.13.1 on Linux

📝 Support `orjson` as a possible backend for `JsonParser` / `JsonRenderer` (#857)


Currently we always use json as a module in JsonParser and JsonRenderer:

django-modern-rest/dmr/parsers.py

Lines 132 to 134 in 69822ff

But, we can make this module customizable. We can pass orjson module there, since it also has a similar API.

Something like:

class JsonParser(Parser):
    __slots__ = ('_json_module', ...)
    def __init__(self, json_module: _JsonModule = json, ...) -> None:
       self._json_module = json_module

And later self._json_module.loads(...)

This would need multiple test cases: install orjson as unit-test dependency and add unit tests for this new renderer / parser.
And we can document that with an example in the integrations.rst docs.

📝 Add a Django command to export OpenAPI schemas (#858)


It migth be useful to people who want to share the schema. Or automate something with it.

I propose to add a django command: dmr_export_schema.
Args:

• Where to find schema, I think we should reuse import_string logic from Django. Required
• All json formatting ones: sort_keys and indent
• Format: json or yaml, check that yaml is installed. Default is json

We should print it to the stdout always. Usages:

# regular:
python manage.py dmr_export_schema server.urls:schema

# pretty:
python manage.py dmr_export_schema server.urls:schema --format json --indent=2 --sort-keys

This would need tests, we can test it as a subprocess, it is a django command after all.
And docs.

📝 UnsolvableAnnotationsError when subclassing a concrete Controller subclass` (#873)


What's wrong?

Bug: UnsolvableAnnotationsError when subclassing a concrete Controller subclass

Description

When creating an intermediate concrete controller class and then subclassing it,
__init_subclass__ raises UnsolvableAnnotationsError even though the serializer
is already resolved on the parent.

Reproduction

from dmr import Controller
from dmr.plugins.pydantic import PydanticSerializer
from dmr.serializer import BaseSerializer
                                                                                                                                                                            
 
class BaseController[T: BaseSerializer](Controller[T]):                                                                                                                     
    pass        


class PydanticController(BaseController[PydanticSerializer]):
    pass


# This raises UnsolvableAnnotationsError
class UserController(PydanticController):
    def get(self) -> ...:
        ...                                                                                                                                                                 
 
Error                                                                                                                                                                       
                
dmr.exceptions.UnsolvableAnnotationsError: Type args () are not correct for <class 'UserController'>,
at least 1 type arg must be provided

Expected behavior

UserController should inherit the serializer from its concrete parent PydanticController,                                                                                   
which already has serializer = PydanticSerializer set.

Thanks for the awesome library, I just started exploring it and I'm really enjoying it so far!

### How it should be?

Subclassing a concrete `Controller` subclass (one that already has a resolved serializer)                                                                                   
should work without requiring the type argument to be re-specified.                                                                                                         
                                                                                                                                                                            
`UserController(PydanticController)` should behave the same as `UserController(BaseController[PydanticSerializer])`.

📝 Feature: Support broker-level ack_policy default with per-subscriber override (#2826)


Problem

Currently ack_policy can only be set per-subscriber:

@broker.subscriber("orders.topic", ack_policy=AckPolicy.NACK_ON_ERROR)
async def handle_order(msg: OrderMessage) -> None:
    ...

There is no way to set a default ack_policy at the broker (or router) level. In practice, most services want the same policy across all subscribers — typically NACK_ON_ERROR for at-least-once delivery with DLQ. This forces every @broker.subscriber() call to repeat the same ack_policy= argument, which is error-prone: forgetting it on a single subscriber silently falls back to ACK_FIRST (at-most-once), which can cause silent message loss.

Proposed solution

Add an ack_policy parameter to KafkaBroker (and equivalently to RabbitBroker, NatsBroker, etc.) that sets the default for all subscribers registered on that broker. Individual subscribers can still override it.

broker = KafkaBroker("localhost:9092", ack_policy=AckPolicy.NACK_ON_ERROR)

# Inherits NACK_ON_ERROR from broker
@broker.subscriber("orders.topic")
async def handle_order(msg: OrderMessage) -> None:
    ...

# Overrides to ACK for this specific subscriber
@broker.subscriber("notifications.topic", ack_policy=AckPolicy.ACK)
async def handle_notification(msg: NotificationMessage) -> None:
    ...

The resolution order would be: subscriber-level > broker-level > built-in default (ACK_FIRST).

Why this matters
• Safety: ACK_FIRST as a silent default is dangerous for services that use DLQ or need at-least-once delivery. A broker-level default lets teams enforce their delivery guarantee in one place.
• DRY: Services with 10+ subscribers shouldn't need to repeat ack_policy=AckPolicy.NACK_ON_ERROR on every one.
• Consistency with other broker-level settings: decoder, middlewares, security, and logger are all broker-level defaults that subscribers inherit. ack_policy is the notable exception.

📝 Optimize `dmr_rf` and `dmr_client` test features for faster tests (#889)


We provide our own fixtures that are subclasses of Django's builtin one.

Django has this code inside: https://github.com/django/django/blob/7dc826b9758d634623a6f5ca05d0ca2048a0ce48/django/test/client.py#L450-L458

    def _encode_json(self, data, content_type):
        """
        Return encoded JSON if data is a dict, list, or tuple and content_type
        is application/json.
        """
        should_encode = JSON_CONTENT_TYPE_RE.match(content_type) and isinstance(
            data, (dict, list, tuple)
        )
        return json.dumps(data, cls=self.json_encoder) if should_encode else data

We need to optimize this method, because json.dumps is slow, but msgspec is fast.
It won't be noticable on 1 tests, but will be on 2k tests (which is the case for our own test base).

See how we conditionally dump our schema here: https://github.com/wemake-services/django-modern-rest/blob/master/dmr/openapi/dump.py

Maybe we should reuse the same for tests?

📝 TagSchema and RoleSchema do not enforce max_length, causing unhandled DB errors (#944)


What's wrong?

The Tag and Role Django models define name = CharField(max_length=100), but the corresponding Pydantic schemas accept any-length strings.

class TagSchema(pydantic.BaseModel):
      name: str  <!-----------------------------HERE                                                                                                                                                                 
                                                        
  class RoleSchema(pydantic.BaseModel):                                                                                                                                                                     
      name: str  <!-----------------------------HERE

When a client sends a name longer than 100 characters, Pydantic validation passes (HTTP 422 is never raised), and the value reaches the database layer where PostgreSQL raises DataError: value too long for type character varying(100). This results in an unhandled 500 instead of a proper 422 validation error. On SQLite the value is silently stored without truncation, masking the bug in tests.

How it should be?

Add max_length constraints to match the model definition:

                                                                                                                                                                                                            class TagSchema(pydantic.BaseModel):                  
    name: str = Field(max_length=100)
                                                                                                                                                                                                            class RoleSchema(pydantic.BaseModel):

📝 Bug: (#2868)


Describe the bug
Can't forward client_rack to aiokafka consumer through FastStream Kafka API.

How to reproduce
Include source code:

from faststream import FastStream

from faststream.kafka import KafkaBroker

# Attempt to configure at broker level

broker = KafkaBroker(
    "localhost:9092",
    client_rack="us-east-1a",  # not supported
)
app = FastStream(broker)

And/Or steps to reproduce the behaviour:

1. Create a KafkaBroker.
2. Try to pass client_rack to the broker constructor.
3. Observe that the parameter is not accepted.
4. There is no alternative way to configure it via subscriber(...) either.

Expected behavior
KafkaBroker should allow passing client_rack (or generic consumer kwargs) and forward it to the underlying aiokafka.AIOKafkaConsumer.

Observed behavior
client_rack is not supported in KafkaBroker constructor, nor in subscriber configuration, so it cannot be passed to aiokafka.

Screenshots
N/A.

Environment
Running FastStream 0.6.7 with CPython 3.14.5 on Linux

Additional context
aiokafka.AIOKafkaConsumer supports client_rack since 0.14.0 version

📝 Feature: Consumer-Only Mode for KafkaBroker (#2879)


When deploying a subscriber-only service, it's common to provision Kafka credentials scoped strictly to READ + DESCRIBE ACLs on specific topics. Today, KafkaBroker always starts a producer during broker.start(), regardless of whether any @broker.publisher is registered. This causes the producer to attempt a connection using consumer-only credentials, which fails or raises errors at the broker/ACL level.

Proposal:

# Option A: broker-level flag
broker = KafkaBroker("localhost:9092", consumer_only=True)

# Option B: skip producer if no publishers are registered (automatic)
# No API change needed — broker inspects registered publishers at start()

🚀 New issue to wemake-services/django-modern-rest by @sobolevn
📝 Add default admin page for `dmr/security/jwt/blocklist` (#1054)


Right now our app for jwt blocklisting has a default model: https://github.com/wemake-services/django-modern-rest/blob/master/dmr/security/jwt/blocklist/models.py

But, it does not have a default admin.py file.
Good example: https://github.com/Dresdn/django-modern-rest/blob/3324d0aecf32509b5434df7e8826d7be6ddac7a8/dmr/security/token/admin.py

This is a very easy task :)
