* `tax: float = 10.5` has a default of `10.5`.
* `tags: List[str] = []` has a default of an empty list: `[]`.

but you might want to omit them from the result if they were not actually stored.

For example, if you have models with many optional attributes in a NoSQL database, but you don't want to send very long JSON responses full of default values.

]

[tool.coverage.run]
parallel = true
source = [
    "docs_src",
    "tests",
    "fastapi"
]
context = '${CONTEXT}'
omit = [
    "docs_src/response_model/tutorial003_04.py",
    "docs_src/response_model/tutorial003_04_py310.py",
]

[tool.ruff.lint]
select = [
    "E",  # pycodestyle errors
    "W",  # pycodestyle warnings

    But the example here uses `PATCH` because it was created for these use cases.

!!! note
    Notice that the input model is still validated.

    So, if you want to receive partial updates that can omit all the attributes, you need to have a model with all the attributes marked as optional (with default values or `None`).

...all these parameters are required because the default value is `...` (Ellipsis).

But now it's possible and supported to just omit the default value, as would be done with Pydantic fields, and the parameters would still be required.

✨ For example, this is now supported:

```Python
from fastapi import Cookie, FastAPI, Header, Path, Query

Puedes instalarlos con `pip install fastapi[all]`.
