+## Using with other query params
+
+When you use Pydantic model schema along with other query params you'll get Pydantic model schema in request body which is wrong:

+
+This is limitation (or bug) from FastAPI. There's already [open issue](https://github.com/fastapi/fastapi/issues/12402) and [related discussions](https://github.com/fastapi/fastapi/issues/12402#issuecomment-2416720739) for this. However, we've nice workaround for [this](https://github.com/fastapi/fastapi/issues/12402#issuecomment-2520205504).
+
+We just have to replace `Query()` with `Depends()` and it'll work as expected:
+
+```diff
+- pagination: Annotated[PaginationPageSize, Query()],
++ pagination: Annotated[PaginationPageSize, Depends()],
+```
