That's why the current versions are still `0.x.x`, this reflects that each version could potentially have breaking changes. This follows the <a href="https://semver.org/" class="external-link" target="_blank">Semantic Versioning</a> conventions.

Por eso las versiones actuales siguen siendo `0.x.x`, esto refleja que cada versión podría tener potencialmente cambios incompatibles. Esto sigue las convenciones de <a href="https://semver.org/" class="external-link" target="_blank">Semantic Versioning</a>.

For example, it doesn't receive `datetime` objects, as those are not compatible with JSON.

So, a `datetime` object would have to be converted to a `str` containing the data in <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO format</a>.

The same way, this database wouldn't receive a Pydantic model (an object with attributes), only a `dict`.

You can use `jsonable_encoder` for that.
