translations, separated by a colon («:»). Use these translations, do not use your own. If an existing translation does not use these terms, update it to use them. In the below list, a term or a translation may be followed by an explanation in brackets, which explains when to translate the term this way. If a translation is preceded by «NOT», then that means: do NOT use this translation for this term. English nouns, starting with the word «the», have the German genus – «der», «die», «das» – prepended to their...

By default, **FastAPI** would automatically convert that return value to JSON using the `jsonable_encoder` explained in [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Because of that, it's now recommended to instead use the `lifespan` as explained above.

## Review PRs

If a PR doesn't explain what it does or why, ask for more information.

A PR should have a specific use case that it is solving.

* If the PR is for a feature, it should have docs.

//// tab | Info

"title" attributes of "abbr" elements are translated following some specific instructions.

Translations can add their own "abbr" elements which the LLM should not remove. E.g. to explain English words.

See section `### HTML abbr elements` in the general prompt in `scripts/translate.py`.

### Return a Response Directly { #return-a-response-directly }

The most common case would be [returning a Response directly as explained later in the advanced docs](../advanced/response-directly.md){.internal-link target=_blank}.

{* ../../docs_src/response_model/tutorial003_02_py39.py hl[8,10:11] *}

This is because by default, FastAPI will inspect every item inside and make sure it is serializable as JSON, using the same [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank} explained in the tutorial. This is what allows you to return **arbitrary objects**, for example database models.
