Remove affects_params lambda. Scoping is now automatic:
Tier 1 - Argument name matching:
If the mutation's args overlap with the context's params by name,
the invalidation is auto-scoped. No developer annotation needed.
@client(context=UserContext)
def user_profile(request, user_id: int) -> UserShape: ...
@client(affects=UserContext)
def update_profile(request, user_id: int, name: str) -> dict: ...
# user_id matches → invalidate: [{context: "user", params: {user_id: 5}}]
Tier 2 - Auth inference (Edge-side, not implemented in framework)
Tier 3 - Broad fallback when no param names match
Also adds function-level affects targeting:
@client(affects='user_profile') # only user_profile, not user_orders
def update_name(request, user_id: int, name: str) -> dict: ...
Function names resolve to their parent context for param lookup.
v1 runtime refetches the whole context regardless, but the protocol
carries the function-level signal for Edge and future optimization.
273 Django tests pass.

mizan (Python)
Django server functions framework. See the monorepo root for full documentation.
Install
uv add "mizan[channels,allauth] @ git+https://git.impactsoundworks.com/isw/mizan.git#subdirectory=django"
Setup
# settings.py
INSTALLED_APPS = ["mizan", ...]
# urls.py
path("api/mizan/", include("mizan.urls"))
# asgi.py (optional, for WebSocket)
from mizan import wrap_asgi
application = wrap_asgi(get_asgi_application())
Define Functions
from mizan.client import client
from mizan.setup.registry import register
from pydantic import BaseModel
class Output(BaseModel):
message: str
@client
def echo(request, text: str) -> Output:
return Output(message=text)
register(echo, "echo")
Register in apps.py:
def ready(self):
import myapp.mizan_clients
Auth
@client(auth=True) # requires authentication
@client(auth='staff') # requires is_staff
@client(auth='superuser') # requires is_superuser
@client(auth=my_callable) # custom check
Contexts
@client(context='global') # fetched once, SSR-hydrated, becomes useCurrentUser()
@client(context='local') # fetched with params, becomes <GreetProvider>
Forms
from mizan.forms import mizanFormMixin, mizanFormMeta
class ContactForm(mizanFormMixin, forms.Form):
mizan = mizanFormMeta(name="contact", title="Contact Us")
name = forms.CharField()
email = forms.EmailField()
def on_submit_success(self, request):
return {"sent": True}
Auto-registers contact.schema, contact.validate, contact.submit. Generates useContactForm() with Zod validation.
Channels
from mizan.channels import ReactChannel
class ChatChannel(ReactChannel):
class Params(BaseModel):
room: str
class DjangoMessage(BaseModel):
text: str
def authorize(self, params):
return self.user.is_authenticated
def group(self, params):
return f"chat_{params.room}"
Generates useChatChannel({ room }).
