In some cases, it's even possible to have both Pydantic v1 and v2 models in the same **path operation** in your FastAPI app:

{* ../../docs_src/pydantic_v1_in_v2/tutorial003_an_py310.py hl[2:3,6,12,21:22] *}

In this example above, the input model is a Pydantic v1 model, and the output model (defined in `response_model=ItemV2`) is a Pydantic v2 model.

### Pydantic v1 parameters { #pydantic-v1-parameters }

 * more ACEs are evaluated until all desired access bits (combined)
 * are "allowed". If all of the desired access bits are not "allowed"
 * the then same process is repeated for inherited ACEs.
 * <p>
 * For example, if user <code>WNET\alice</code> tries to open a file
 * with desired access bits <code>0x00000003</code> (<code>FILE_READ_DATA |
 * FILE_WRITE_DATA</code>) and the target file has the following security
 * descriptor ACEs:

Bevor wir tiefer in das **Dependency Injection** System eintauchen, lassen Sie uns das vorherige Beispiel verbessern.

## Ein `dict` aus dem vorherigen Beispiel { #a-dict-from-the-previous-example }

Im vorherigen Beispiel haben wir ein <abbr title="Dictionary – Zuordnungstabelle: In anderen Sprachen auch Hash, Map, Objekt, Assoziatives Array genannt">`dict`</abbr> von unserer Abhängigkeit („Dependable“) zurückgegeben:

            Maps.asMap(graph.adjacentNodes(node), successorNodeToValueFn));
  }

## Check the username { #check-the-username }

Here's a more complete example.

Use a dependency to check if the username and password are correct.

Combining encryption and compression is not safe in all setups.
This is particularly so if the compression ratio of your content reveals information about it.
See [CRIME TLS](https://en.wikipedia.org/wiki/CRIME) as an example of this.

Therefore, compression is disabled when encrypting by default, and must be enabled separately.

            String url = "http://example.com";
            assertThrows(MalformedURLException.class, () -> new DummySmbResourceLocator(url));

    # o sqlPackage: (NotRequired - Default all packages)
    #  The package of SQL file for outsideSql.
    #  This is basically for narrowing SQL-searching target,
    #  for example, when the project has SQL files for other framework.
    #  So basically you don't need this.
    #
    #  You can use variable '$$PACKAGE_BASE$$' that means 'packageBase'.

By using all the previous alternatives I had the chance to learn from all of them, take ideas, and combine them in the best way I could find for myself and the teams of developers I have worked with.

For example, it was clear that ideally it should be based on standard Python type hints.

Also, the best approach was to use already existing standards.

 * annotated by {@link TestSubtype}.
 *
 * <p>These declaration methods rely on Java static type checking to make sure what we want to
 * assert as subtypes are really subtypes according to javac. For example:
 *
 * {@snippet :
 * class MySubtypeTests extends SubtypeTester {
 *   @TestSubtype(suppressGetSubtype = true, suppressGetSupertype = true)
 *   public <T> Iterable<? extends T> listIsSubtypeOfIterable(List<T> list) {
