The `TestClient` is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, and luckily, we can use it directly to test the API.

## Example { #example }

Например, он не принимает объекты `datetime`, так как они не совместимы с JSON.

В таком случае объект `datetime` следует преобразовать в строку соответствующую <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">формату ISO</a>.

Точно так же эта база данных не может принять Pydantic-модель (объект с атрибутами), а только `dict`.

		setMap[a.Column.Name] = a.Value
	}

	for _, ref := range rel.References {
		fkNil[ref.ForeignKey.DBName] = nil

		if ref.OwnPrimaryKey && ref.PrimaryKey != nil {
			ownerPKNames = append(ownerPKNames, ref.PrimaryKey.DBName)
			primaryColumns = append(primaryColumns, clause.Column{Name: ref.PrimaryKey.DBName})
			foreignColumns = append(foreignColumns, clause.Column{Name: ref.ForeignKey.DBName})

Here are the steps to help with translations.

#### Tips and guidelines

            "schemas": {
                "HTTPValidationError": {
                    "properties": {
                        "detail": {
                            "items": {
                                "$ref": "#/components/schemas/ValidationError",
                            },
                            "title": "Detail",
                            "type": "array",
                        },
                    },

	rlk, err := RLockedOpenFile(f.Name())
	if err != nil {
		t.Fatal(err)
	}
	isClosed := rlk.IsClosed()
	if isClosed {
		t.Fatal("File ref count shouldn't be zero")
	}

	// Increase reference count to 2.
	rlk.IncLockRef()

	isClosed = rlk.IsClosed()
	if isClosed {
		t.Fatal("File ref count shouldn't be zero")
	}

	// Decrease reference count by 1.
	if err = rlk.Close(); err != nil {
		t.Fatal(err)
	}

For example, it doesn't receive `datetime` objects, as those are not compatible with JSON.

So, a `datetime` object would have to be converted to a `str` containing the data in <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO format</a>.

The same way, this database wouldn't receive a Pydantic model (an object with attributes), only a `dict`.

There are many other ASGI middlewares.

For example:

* <a href="https://github.com/florimondmanca/msgpack-asgi" class="external-link" target="_blank">MessagePack</a>

OpenAPI також додала `example` і `examples`  до інших частин специфікації:

* <a href="https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object" class="external-link" target="_blank">`Parameter Object` (в специфікації)</a> використовується FastAPI для:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`

これを使うことで、いくつかのFlaskフルスタックジェネレータを作成することになりました。これらは私 (といくつかの外部のチーム) が今まで使ってきたメインのスタックです。
