You can declare multiple `File` and `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `multipart/form-data` instead of `application/json`.

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.

## Important Notes

### No Database Changes Required

- Language configuration is entirely file-based
- No database or OpenSearch index updates needed
- Settings are loaded at application startup and cached

### Fallback Mechanism

If a translation is missing in `fess_label_[locale].properties`, Fess automatically falls back to the base `fess_label.properties` (English).

### Language Code Format

Later, when reading about how to structure bigger applications ([Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md)), possibly with multiple files, you will learn how to declare a single `dependencies` parameter for a group of *path operations*.

## Global Dependencies { #global-dependencies }
