## Segunda dependência, "dependable" e "dependente" { #second-dependency-dependable-and-dependant }

Então, você pode criar uma outra função para uma dependência (um "dependable") que ao mesmo tempo declara sua própria dependência (o que faz dela um "dependente" também):

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

Vamos focar nos parâmetros declarados:

///

### Importando `Depends` { #import-depends }

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

### Declarando a dependência, no "dependente" { #declare-the-dependency-in-the-dependant }

Da mesma forma que você utiliza `Body`, `Query`, etc. Como parâmetros de sua *função de operação de rota*, utilize `Depends` com um novo parâmetro:

This is quite simple (not very useful), but will help us focus on how the sub-dependencies work.

## Second dependency, "dependable" and "dependant" { #second-dependency-dependable-and-dependant }

Then you can create another dependency function (a "dependable") that at the same time declares a dependency of its own (so it is a "dependant" too):

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

Let's focus on the parameters declared:

## Zweite Abhängigkeit, „Dependable“ und „Dependant“ { #second-dependency-dependable-and-dependant }

Dann können Sie eine weitere Abhängigkeitsfunktion (ein „Dependable“) erstellen, die gleichzeitig eine eigene Abhängigkeit deklariert (also auch ein „Dependant“ ist):

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

Betrachten wir die deklarierten Parameter:

        return project;
    }

    private Dependency toDependency(MavenProject mavenProject) {
        Dependency dependency = new Dependency();
        dependency.setGroupId(mavenProject.getGroupId());
        dependency.setArtifactId(mavenProject.getArtifactId());
        dependency.setVersion(mavenProject.getVersion());
        return dependency;
    }

    * Required scopes `["items"]` with the dependency:
    * `get_current_active_user`:
        *  The dependency function `get_current_active_user` has:
            * Required scopes `["me"]` with the dependency:
            * `get_current_user`:
                * The dependency function `get_current_user` has:
                    * No scopes required by itself.
                    * A dependency using `oauth2_scheme`.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection" { #what-is-dependency-injection }

## Segunda dependencia, "dependable" y "dependant" { #second-dependency-dependable-and-dependant }

Luego puedes crear otra función de dependencia (un "dependable") que al mismo tiempo declare una dependencia propia (por lo que también es un "dependant"):

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

Centrémonos en los parámetros declarados:

Ele sempre terá os escopos de segurança declarados nas dependências atuais de `Security` e todos os dependentes para **aquela** *operação de rota* **específica** e **aquela** árvore de dependência **específica**.

Es ist so konzipiert, sehr einfach zu verwenden zu sein und es jedem Entwickler sehr leicht zu machen, andere Komponenten mit **FastAPI** zu integrieren.
