How to hide `Schemas` section in `/docs`?

from fastapi import FastAPI
from pydantic.main import BaseModel

app = FastAPI()

class Model(BaseModel):
    a: str

@app.get("/", response_model=BaseModel)
def get():
    return {"a": "b"}

After uvicorn app:app, /docs shows this:

Is there any way to hide Schemas section with the BaseModel? I don’t want to remove the schema definitions from the API spec. Instead, I just want to remove them from the render. I’ve checked out Extending OpenAPI, but didn’t find anything related.

I found How to hide the Models section in Swagger UI? which mentions a field called defaultModelsExpandDepth, but not sure how I could configure such a thing through FastAPI.

FastAPI now supports passing swagger parameters, so to hide the schemas you can do it as below:

app = FastAPI(
    title="API",
    swagger_ui_parameters={"defaultModelsExpandDepth": -1}
)

I found out how to do this, I had to add defaultModelsExpandDepth: -1, (like the SO answers say) to https://github.com/tiangolo/fastapi/blob/master/fastapi/openapi/docs.py#L40, and then serve the custom generated HTML myself through https://fastapi.tiangolo.com/advanced/extending-openapi/#serve-the-static-files. Will open formal merge request for this soon, and close issue around then.

it works. thank’s.
