* `upgrade`: Upgrades

Das System (in diesem Fall **FastAPI**) kümmert sich dann darum, Ihren Code mit den erforderlichen Abhängigkeiten zu versorgen („die Abhängigkeiten einfügen“ – „inject the dependencies“).

Das ist sehr nützlich, wenn Sie:

* Eine gemeinsame Logik haben (die gleiche Code-Logik immer und immer wieder).

# Security Tools

When you need to declare dependencies with OAuth2 scopes you use `Security()`.

But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

        String scope(); // default: all

        /**
         * Returns the type of pointer, which is always DEPENDENCIES for a DependenciesPointer.
         *
         * @return the DEPENDENCIES pointer type
         */
        @Override
        default Type type() {
            return Type.DEPENDENCIES;
        }
    }

    interface ChildrenPointer extends Pointer {
        /**

 * followed by <dfn>flattening</dfn> and <dfn>resolution</dfn>.
 * The version selection is done for each dependency during the collection phase.
 * The flatten phase keeps only a single version per ({@code groupId}, {@code artifactId}) pair.
 * The resolution phase actually downloads the dependencies (or artifacts) that have been computed.

## Create a `get_current_user` dependency { #create-a-get-current-user-dependency }

Let's create a dependency `get_current_user`.

Remember that dependencies can have sub-dependencies?

`get_current_user` will have a dependency with the same `oauth2_scheme` we created before.

            mockThemeHelper.install(artifact);
            assertTrue(true); // Should complete without exception
        } catch (Exception e) {

            assertTrue(true);
        }
    }
