When you type a **command** in the terminal, the operating system **looks for** the program in **each of those directories** listed in the `PATH` environment variable.

For example, when you type `python` in the terminal, the operating system looks for a program called `python` in the **first directory** in that list.

Entonces podemos usar la dependencia con:

/// info | Información

Fíjate que solo estamos declarando una dependencia en la *path operation function*, `query_or_cookie_extractor`.

Pero **FastAPI** sabrá que tiene que resolver `query_extractor` primero, para pasar los resultados de eso a `query_or_cookie_extractor` al llamarlo.

También puedes usar `url_for()` dentro de la plantilla, toma como argumentos los mismos que usaría tu *path operation function*.

Entonces, la sección con:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...generará un enlace hacia la misma URL que manejaría la *path operation function* `read_item(id=id)`.

Por ejemplo, con un ID de `42`, esto se renderizaría como:

```html

        String message = "LDAP operation failed";
        LdapOperationException exception = new LdapOperationException(message);

        assertEquals(message, exception.getMessage());
        assertNull(exception.getCause());
    }

    public void test_constructor_withMessageAndCause() {
        // Test constructor with message and cause
        String message = "LDAP operation failed with error";

 *   <li>The {@code copyOf} methods will sometimes recognize that the actual copy operation is
 *       unnecessary; for example, {@code copyOf(copyOf(anArrayList))} should copy the data only
 *       once. This reduces the expense of habitually making defensive copies at API boundaries.
 *       However, the precise conditions for skipping the copy operation are undefined.

В этом случае они будут применяться ко всем *операциям пути* в приложении:
