## Integrated middlewares

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.

/// note | "Technical Details"

For the next examples, you could also use `from starlette.middleware.something import SomethingMiddleware`.

# o isCheckProcedureDiff: (NotRequired - Default false)
# o loadDataReverseMap: (NotRequired - Default map:{})
# o schemaSyncCheckMap: (NotRequired - Default map:{})
# o propertiesHtmlMap: (NotRequired - Default map:{})
#
# Example:
# map:{
#     ; documentOutputDirectory = ./output/doc
#     ; aliasDelimiterInDbComment = :
#     ; isDbCommentOnAliasBasis = true
#     ; isEntityJavaDocDbCommentValid = true
#     ; isEntityDBMetaDbCommentValid = true

   * Returns the maximal range {@linkplain #encloses enclosed} by both this range and {@code
   * connectedRange}, if such a range exists.
   *
   * <p>For example, the intersection of {@code [1..5]} and {@code (3..7)} is {@code (3..5]}. The
   * resulting range may be empty; for example, {@code [1..5)} intersected with {@code [5..7)}
   * yields the empty range {@code [5..5)}.
   *

With `Form` you can declare the same configurations as with `Body` (and `Query`, `Path`, `Cookie`), including validation, examples, an alias (e.g. `user-name` instead of `username`), etc.

/// info

`Form` is a class that inherits directly from `Body`.

/// info

In Pydantic v1 the method was called `.dict()`, it was deprecated (but still supported) in Pydantic v2, and renamed to `.model_dump()`.

The examples here use `.dict()` for compatibility with Pydantic v1, but you should use `.model_dump()` instead if you can use Pydantic v2.

### About `**user_in.dict()`

#### Pydantic's `.dict()`

To see all the options you have, checkout <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">Pydantic's Type Overview</a>. You will see some examples in the next chapter.

For example, as in the `Image` model we have a `url` field, we can declare it to be an instance of Pydantic's `HttpUrl` instead of a `str`:

//// tab | Python 3.10+

```Python hl_lines="2  8"

You will learn more about adding extra information later in the docs, when learning to declare examples.

/// warning

Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.
As these keys may not necessarily be part of the OpenAPI specification, some OpenAPI tools, for example [the OpenAPI validator](https://validator.swagger.io/), may not work with your generated schema.
