Adding root_path breaks admin page

Describe the bug

I have multiple endpoints and admin panel. I want my endpoints to be in root path of /api/v1/, but admin to be just /admin/. So, I added app_configs["root_path"] = f"/api/v{settings.APP_VERSION}", and admin panel breaks down.

Steps to reproduce the bug

app_configs: dict[str, Any] = {"title": "Itinerago API"}
app_configs["root_path"] = f"/api/v{settings.APP_VERSION}"

app = FastAPI(**app_configs)
app.include_router(auth_router, prefix="/auth", tags=["Auth"])
app.include_router(core_router, prefix="", tags=["Main Logic"])


admin = Admin(app, engine)

# admin.add_view-s here

Commenting out second line fixes admin, however, it does not give desired output.

Expected behavior

APIs will have /api/v1/ prefix, but, admin will not. Admin will load without a problem.

Actual behavior

Admin breaks down completely:

and

Links are also broken:
In the first image, when you click one of the models it goes to: /api/v1/admin/model/list

Debugging material

No response

Environment

Windows, Python 3.10, Dockerized Fastapi
sqladmin version 0.12.0

Hey,
not sure if I get your question right.
I can think of two points:

• Use can use Admin(base_url=...) to configure the URL.
• In your app you don't se the root_path in path, instead that's the prefix in your routers.

Generally I think this makes sense since you want to handle multiple API versionings in your app, running at the same time so setting the version on the whole app might not be a good idea.

Default base_url suits me, however, whenever set any root_path, admin gets messy like I showed in screenshots. You second point would work, but, it is hassle to add api/v1/ to every app's router. I think admin should be independent of root_path and have its url.

Anyway if you want to do that you can just modify admin.app which is just another FastAPI app so you can do any config you want.

How? Just adding root_path breaks admin panel. Is it expected?

[aminalaee]

I haven't tested this before, doesn't setting this work?

admin.app["root_path"] = ...

[mmzeynalli]

Just checked, no it does not work. Change the line to:
admin.app.root_path = "", but as app passed to admin is the global fastapi app, I am overriding global root_path => All endpoints are without /api/v1/

@mmzeynalli have you solved this problem?

[mmzeynalli]

To be honest no, unfortunately, have been super busy for the last couple of months.

A workaround I found is to use a middleware:

@app.middleware("http")
async def fix_admin_root_path(request, call_next):
    if request.url.path.startswith("/admin/"):
        request.scope["path"] = app.root_path + request.url.path
    return await call_next(request)
