Ви можете створювати залежності, які мають підзалежності.

Вони можуть бути настільки глибокими, наскільки потрібно.

FastAPI подбає про їх розв'язання.

## Перша залежність «dependable» { #first-dependency-dependable }

Можна створити першу залежність («dependable») так:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

                .filter(s -> s != null);
    }

    /**
     * Gets the content description from highlighted fields.
     * Returns the first non-blank highlighted field content.
     *
     * @param document the document data map
     * @return the content description with highlighting
     */

		t.Fatalf("Failed to create data with default value, got: %+v", harumph)
	}

	var result Harumph
	if err := DB.First(&result, "email = ?", "******@****.***").Error; err != nil {
		t.Fatalf("Failed to find created data, got error: %v", err)

    class IntegrationTests {

        @Test
        @DisplayName("Should handle multiple consecutive reads")
        void testMultipleConsecutiveReads() throws Exception {
            // First read
            byte[] buffer1 = createValidOplockBreakBuffer((byte) 0x01, createTestData(16));
            notification.readBytesWireFormat(buffer1, 0);

            // Second read with different values

	//      this is OK since r0 == $0, but the latter is preferred.
	ADD $0, R6, R5             	// 7ca60214

        //TODO: the assembler rewrites these into ADDIS $19, R5, Rx and ADD $-10617, Rx, Rx, but the test only sees the first ADDIS
	ADD $1234567, R5                // 3ca50013 or 0600001238a5d687
	ADD $1234567, R5, R6            // 3cc50013 or 0600001238c5d687

	ADDEX R3, R5, $3, R6            // 7cc32f54

    }
  }

  inline fun <reified T : CallEvent> removeUpToEvent(): T = removeUpToEvent(T::class.java)

  inline fun <reified T : CallEvent> findEvent(): T = eventSequence.first { it is T } as T

  /**
   * Remove and return the next event from the recorded sequence.
   *
   * @param eventClass a class to assert that the returned event is an instance of, or null to
   *     take any event class.

Puedes crear dependencias que tengan **sub-dependencias**.

Pueden ser tan **profundas** como necesites.

**FastAPI** se encargará de resolverlas.

## Primera dependencia "dependable" { #first-dependency-dependable }

Podrías crear una primera dependencia ("dependable") así:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

	VSOXEI32V	V3, V2, (X10)			// a761250e
	VSOXEI32V	V3, V2, V0, (X10)		// a761250c
	VSOXEI64V	V3, V2, (X10)			// a771250e
	VSOXEI64V	V3, V2, V0, (X10)		// a771250c

	// 31.7.7: Unit-stride Fault-Only-First Loads
	VLE8FFV		(X10), V8			// 07040503
	VLE16FFV	(X10), V8			// 07540503
	VLE32FFV	(X10), V8			// 07640503
	VLE64FFV	(X10), V8			// 07740503
	VLE8FFV		(X10), V0, V8			// 07040501

            sinceTags.isEmpty() -> {
                fallback?.let { SinceTagStatus.Present(it) } ?: SinceTagStatus.Missing
            }

            sinceTags.all { it == sinceTags.first() } -> {
                (sinceTags.first() ?: fallback)?.let { SinceTagStatus.Present(it) } ?: SinceTagStatus.Missing
            }

            else -> {
                SinceTagStatus.Inconsistent(sinceTags)
            }
        }

**Alt bağımlılıkları** olan bağımlılıklar oluşturabilirsiniz.

İhtiyacınız olduğu kadar **derine** gidebilirler.

Bunları çözme işini **FastAPI** üstlenir.

## İlk bağımlılık "dependable" { #first-dependency-dependable }

Şöyle bir ilk bağımlılık ("dependable") oluşturabilirsiniz:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}
