Aynı şekilde bu veritabanı bir Pydantic model'i (attribute'lara sahip bir obje) de kabul etmez; yalnızca bir `dict` kabul eder.

Bunun için `jsonable_encoder` kullanabilirsiniz.

Bir Pydantic model gibi bir obje alır ve JSON ile uyumlu bir versiyonunu döndürür:

{* ../../docs_src/encoder/tutorial001_py310.py hl[4,21] *}

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[1,13] *}

**FastAPI**, sizin için `BackgroundTasks` tipinde bir obje oluşturur ve onu ilgili parametre olarak geçirir.

Ainsi, un objet `datetime` doit être converti en une `str` contenant les données au [format ISO](https://en.wikipedia.org/wiki/ISO_8601).

De la même manière, cette base de données n'accepterait pas un modèle Pydantic (un objet avec des attributs), seulement un `dict`.

Vous pouvez utiliser `jsonable_encoder` pour cela.

Elle reçoit un objet, comme un modèle Pydantic, et renvoie une version compatible JSON :

// in the usual way by the opcode itself. Asm must use AMRC for both instructions, so
// we return the opcode for MRC so that asm doesn't need to import obj/arm.

	if op == arm.AMRC {
		op1 = 1
	}
	bits, ok := ParseARMCondition(cond)
	if !ok {
		return
	}
